Description

  The present invention provides a mechanism design support method and a mechanism design for navigating a worker by various methods in addition to presenting work contents to be performed by the worker to a worker who performs a mechanism design work of a specific model of a certain product. The present invention relates to a support system and a mechanism design support program.

  In the past, when designing a new product, the mechanism design was performed while performing the work of determining the physical shape, dimensions of each part, necessary parts, the positional relationship between parts, etc. while repeating trial and error. . Until now, it was necessary for a single designer to repeatedly design products of the same category many times in order to be able to design in a short period of time while maintaining a quality level above a certain level. In addition, by repeating product design of the same category many times in this way, you will gradually become accustomed to the design of that product, and you will be able to acquire your own design know-how. It was difficult for them to share such know-how with other designers.

However, as the demands of product buyers diversify and multi-product, low-volume production becomes more common, it will be necessary to bring many models into the market one after another even in the same category. Along with this, there is an increasing demand to significantly reduce the time required for designing each model. For this reason, it has become an important issue to design inexperienced designers in many product design sites with a certain level of quality and in a short period of time for each model.
An object of the present invention is to solve such a problem.

  In order to solve the above-described problems, the present invention provides a mechanism design support method, a mechanism design support system, and a mechanism design support program that support a designer who performs a mechanism design of a product using a computer.

  Therefore, on the computer, design specifications, component parts, design items, relations between the design specifications and the component parts, and relations between the design items and the design specifications or the component parts necessary for designing the product are calculated. A construction process for defining and registering in the database is provided. Specifically, when developing and designing a product, first, what design items, what design specifications, and what parts are needed from engineers who are familiar with the design of the product We will conduct interview surveys and register the results in the database.

  And, for a specific model of the product, by providing a design specification determination step that presents the design specification to the designer by a computer, and prompts the determination of the contents of the design specification by adding, changing, and deleting as necessary. Based on the relationship between the design specifications registered in the construction process and the component parts, the component parts used in the specific model are extracted from the database and presented to the designer, and added / changed / deleted as necessary. Providing a component part determination step that prompts the designer to determine the component part on the computer, and based on the relationship between the design item registered in the construction step and the design specification or the component part, the specifying by the computer The design items necessary for the model are extracted, the design items used for the specific model are extracted from the database and presented to the operator, and added / changed / The design item determination process that prompts the operator to determine the design item is performed on the computer, and the specific work contents of the design item determined in the design item determination process are presented to the designer by the computer, and the design is performed. A design item execution step is provided for navigating the person and encouraging the execution of the work contents.

  Further, in the construction step, the respective temporal priorities are set for each design item, and the design items extracted in the design item extraction step are set based on the prior relationships set for each. A design flow diagram can be created on a computer. For example, the setting of the predecessor relationship is a design item that must be completed in order to start work on a certain design item, or a design item that can be started when work on a certain design item is completed. This can be done by associating.

  Further, when there is a document relating to each design item in the construction process, the document and the association data between the design item and the document are stored, and in the design process execution process, an operator performs a specific work on the design item. Sometimes, when there is a document associated with the design item, the content can be extracted based on the association data and presented to the operator.

  In the design item performing step, the once completed design item can be returned to an unfinished state while leaving the obtained data, and the execution of the design item can be performed again.

  As described above, according to the present invention, the design specifications, component parts, design items, the relationship between the design specifications and the component parts, and the design items and the design specifications or the configurations necessary for product design are described. By defining the relationship with the parts and registering them in the database, the designer is encouraged to determine the contents of the design specifications for the specific model of the product, and the component parts used in the specific model are extracted from the database and designed To the designer and add / change / delete as necessary to prompt the designer to determine the components, extract the design items necessary for the specific model and present it to the designer, and the design The specific work content of the design item extracted in the item extraction process can be presented to the designer, and the designer can be navigated to promote the execution of the work content. As a result, even if a designer with little experience in designing the product, who does not know in detail what kind of work should be done in accordance with the procedure, even if the work proceeds according to the contents of this navigation, Design can be performed at a standard, and the time required for design can be shortened.

  A design navigation system realized as an embodiment of the present invention will be described below with reference to the drawings. The design navigation system of this embodiment is basically composed of a computer and a computer program executed on the computer. Further, a system can be configured by combining a computer and a computer program executed on the computer.

  The design navigation system of this embodiment can be broadly divided into two modes, “construction mode” and “execution mode”. “Building mode” refers to the overall shape of a certain product, for example, a mobile phone, the physical shape of each part, the parts expected to be used, the positional relationship between parts, the strength required for each part, etc. In this mode, the design specifications required to perform mechanical design, the mechanical components that are expected to be used, and the design items that are expected to require design work are correlated with each other and registered in the database. . In other words, in this mode, information necessary for navigating the design work of the mechanism designer is prepared in advance prior to the design work.

  On the other hand, the “execution mode” is a design item or design specification necessary for mechanism design of a specific model of a certain product (for example, a specific model of a mobile phone product) based on the information prepared in the construction mode. In this mode, mechanical parts are extracted and, for example, an operator who actually performs design work on a CAD system is navigated.

  In this embodiment, the execution mode is divided into two stages of “concept design” and “detailed design” in consideration of the contents of the design work. In “concept design”, a design flow is generated that indicates the extraction of design items necessary for performing the mechanical design of the model and the order in which those design items are executed. In the “detailed design”, according to the design flow shown in the conceptual design, design items to be mechanically designed at that time are presented to the detailed designer, and necessary design work is urged in the design items. However, the division of “concept design” and “detailed design” is merely an example, and the present invention is not limited to such division, and the execution mode is a series of procedures, or three or more It is also included in the technical scope of the present invention.

  When the design navigation system of this embodiment is activated, a login screen (not shown) appears first. When the user name and password of an authorized user are entered here and the “OK” button is clicked, the dialog box shown in FIG. 1 is displayed. In this dialog box, selection buttons including the above-mentioned “construction mode”, “concept design”, and “detailed design” are displayed, and any one of these can be selected by clicking. Hereinafter, the design navigation system of this embodiment will be described in the order of “construction mode”, “concept design”, and “detailed design”.

[Build mode]
In the construction mode, as described above, information necessary for navigating a designer's design work mainly in concept design and detailed design is prepared on a computer in advance and registered in a database prior to the design work. FIG. 2 is a flowchart showing the overall procedure of the work in the construction mode. Below, the case where information required as a system for supporting the operator who performs the mechanism design of a mobile phone is constructed using this construction mode will be described.

  Even if the product category is a mobile phone, the design will naturally differ for different models. However, if the product is of the same category, such as a mobile phone, there are many common parts even if the model is different. Therefore, in the construction mode, basic information related to the mechanism design of products belonging to the category of mobile phone is registered.

  When the “construction mode” button is clicked in the dialog box of FIG. 1, the system enters the construction mode and the screen shown in FIG. 3 appears. In the dialog box of FIG. 3, three options of “design information registration”, “component registration”, and “design item registration” are displayed, and the work to be performed is selected and clicked. . Here, “design information registration” corresponds to the work “registration of design specifications” (S203) in the flowchart of FIG. 2, and “component registration” corresponds to the work “registration of component parts” (S202) in FIG. The “design item registration” corresponds to the operation of “registration of design items constituting the design flow” (S204) in FIG.

  First, “design information registration” will be described. When the “design information registration” button is clicked in the dialog box of FIG. 3, the screen of FIG. 4 appears. This is a dialog box for registering design information, in other words, design specifications. In FIG. 4, a design information name such as “design specification 1” is already registered in the column “design information name”, but such a design information name is not registered when the system is operated. To register the design information name, right-click on this part and click the “Add” button (not shown) from the several choices that appear. Enter the appropriate name in the design information name entry field that appears. By pressing the return key, the name just entered is added to the end of the column “design information name”.

  The design information name added in this way can be registered in association with the “design information value” on the right side. If the design information value in this case is a form in which the designer selects an appropriate value from a plurality of design information value options at the time of mechanical design, enter and register a plurality of values as options. To do. In the example of FIG. 4, two values “value 3α” and “value 3β” are registered as options for the design information name “evaluation measure 3”. Further, in the column “Please enter comments regarding design information” at the bottom, some information regarding this “evaluation measure 3” can be described as a comment. In addition, the comment described in the column “Please enter comments regarding design information” is useful information that can be easily referred to by the operator when performing detailed design. In the same manner, necessary design specifications are registered in the column of design information name, and appropriate design information values are registered for the respective design specifications as necessary. The registered information is stored in a database (DB) of the system according to a predetermined format.

  Next, “component registration” will be described. When the “Register Component” button is clicked in the dialog box of FIG. 3, the screen of FIG. 5 appears (S202). This is a dialog box for registering mechanical parts that are expected to be used in the product. In the case of FIG. 5 as well, nothing is initially registered in the “part name” column. To register a part name, right-click on this part, click the “Add” button (not shown) from the choices that appear, and enter the appropriate name when the part name entry field appears. Press the return key. As a result, the name just entered is added to the end of the “part name” field. In this way, the part name can be registered by a simple operation.

  Further, information regarding the input component is registered in the right column of the “component name” column. Here, a case where information related to a part “part 1” is registered will be described. In this example, since it is desired to prepare two types of component type A and component type B for “component 1”, the A column on the right side shows a state where a field of “component type name” is created. It is possible to use lower part types. In addition, fields such as “part number” in the B column, “material” in the C column, “cost” in the D column, and “internal design” in the E column are created. These fields can be arbitrarily defined by those who work in the construction mode. The operator inputs necessary values and characters for each of these prepared fields.

  For the part, it is necessary to define the relationship with the design specification (S205). The matrix after the I column is a matrix for defining this relationship. The design specifications registered in the column of “design information name” and the “design information value” registered in accordance with the column are displayed after column J. Right-click on the desired cell and select “Set as extraction condition” to be displayed. A “◯” mark is displayed in that cell. In the example of FIG. 5, the design specification value 1a of the design specification 1 is associated with the component “type A” of “part 1”, and the design type “part B” of “part 1” is associated with the design. A design specification of value 1b of specification 1 is associated.

  In this way, the relationship between the design specification and the parts related to the design specification can be easily defined, and the information defined here is used in the subsequent execution mode (conceptual design and detailed design). For example, if the operator selects “value 1a” in “design specification 1” in the detailed design, “type A” of “part 1” is extracted as a part that matches it. If the operator selects “value 1b” in “design specification 1”, “type B” of “part 1” is extracted as a part that matches the value. In this way, because the computer can automatically extract parts corresponding to the design specifications based on the defined relationship, the necessary and appropriate parts can be selected even if the person performing the design work is inexperienced. It becomes possible.

  Next, “design item registration” will be described. When the “design item registration” button is clicked in the dialog box of FIG. 3, the screen of FIG. 6 appears (S204). This is a dialog for registering the design item itself (left side of the figure) and entering and editing properties related to a specific design item (here "design item 1-1-2") (right side of the figure) Is a box.

  The example of FIG. 6 is a dialog box at the stage where registration of design items has already progressed to some extent, and at the stage when the construction mode is first launched, it is a hierarchy below “main body” in the tree display on the left side of the figure. “Part 1” and the like have been registered, but “part 1-1” and “design item 1-1-1”, which are lower layers, are not initially registered. In this case, the operator can register “parts” and “design items” one by one in a predetermined procedure.

  In the tree display screen on the left side of FIG. 6, in addition to the design items, “parts” that require the design items to be designed and “parts” related to the design items can be registered. However, this is for the purpose of presenting to the operator in an easy-to-understand manner what kind of parts and parts a certain design item relates to, and the parts such as “part 1” registered here. There is no direct relationship with the association with the design items and design specifications performed in other operations of this embodiment.

  When a new item is registered on the tree display screen on the left side of FIG. 6, the item is displayed at a predetermined position in the tree. The depth of the tree hierarchy can be freely determined by the worker in consideration of the ease of construction work and the like. However, in the system of the present embodiment, a rule is set that the lowest hierarchy is a design item. In order to register that the registered item is a design item, the operator designates that separately. As an example, when “design item 1-1-2” is newly registered in the lowest hierarchy of the tree and this is designated as a design item, “design item 1-1-2” is selected. In the state, click on the button “Determine as simulation target” on the right side of the tree (in FIG. 6, since the design item and the set item have already been selected, the display switches to “Remove from simulation target”). The item is registered as a design item, and the operator inputs information on the design item in each column of the dialog box for inputting / editing the property shown on the right side of FIG.

  The design items listed on the tree display screen on the left side of FIG. 6 include not only the design items necessary for the design of a specific model of a product, but also the design items of all products in the category to which the model belongs. It is desirable to do. This makes it possible to navigate the design worker for all products belonging to the category using the present system. As an example, there are about 300 design items required for the design of one model belonging to the product category of mobile phones. This is not limited to this model and is required for the design of all models of mobile phones to be designed using this system. The total design items can reach thousands. In that case, the design items required for the design of a specific model of a certain product are only a part of all the design items of the product listed here, but all the design items are listed in the tree on the left side of FIG. Is done.

  In the dialog box on the right side of FIG. 6, “design item name” indicating that the input / edit dialog box for this property is “design item 1-1-2” is displayed at the top. Below that, columns of “design item function”, “parent information”, “requirement”, and “related know-how” are provided.

  In “design item function”, an explanation of what function the design item has is input. Here, it is desirable to input a description so that a person who performs detailed design later can understand the outline of the design item at a glance.

  “Parent information” is a column for defining a design item (this is referred to as “parent item”) that must be completed in order to execute the work of the design item. This item must be input in order to create a design flow diagram showing the processing procedure of each design item (S207). As shown in FIG. 7, the parent item can be defined by dragging and dropping “design item 1-1-1” to be the parent item from the tree display on the left side to this column. As shown in the table, “design item 1-1-1” is displayed in the “parent information” column, and it is defined that the parent item of “design item 1-1-2” is “design item 1-1-1”. Is done.

  Note that there may be a case where a plurality of design items must be completed in order to start the design of a certain design item. Therefore, the design item to be a parent item is not necessarily one. In that case, a plurality of design items are displayed in the “parent information” column.

  When all the parent information is set for each design item, it is possible to automatically check whether there is a logical contradiction in the set contents by clicking the “simulation execution” button in FIG. This is because a simulator program prepared in advance is executed. In this embodiment, the design item that must be completed in order for the design item to be executed, that is, parent information is registered. However, the design item is newly executed when the design item is completed. It is also possible to register a design item (this is referred to as a “child item”) that enables the user to be able to

  The following “necessary condition” column is a column for associating this design item with the above-mentioned design specification or part, and must be input (S206) (if there is no input, in the design item determining step) Design items that are not extracted). Information set in the “Required Conditions” column of the dialog box on the right side of FIG. 6 defines conditions for extracting design items required for the design of a specific model from all design items. .

  When the “add” button on the right side of the “requirement” column is clicked, a dialog box shown in FIG. 8 appears. Here, all the design specifications and parts already registered through the dialog boxes of FIGS. 4 and 5 are displayed. When a predetermined part is selected from the “component list” on the left side in the dialog box of FIG. 8 and the top check box is clicked, a check mark is displayed in the check box. As a result, this design item is associated with a specific part. Similarly, when a predetermined design information name (that is, design specification) is selected from the “design information list” on the right side of FIG. 8 and a check box at the top is clicked, a check mark is displayed in the check box. As a result, this design item is associated with a specific design specification.

  In the above, the reason that the design item is “associated with the design specification“ or ”part” is as follows. Generally speaking, since the design specification and the part are associated with each other, it can be considered that the design item is associated with only one of the design specification and the part. However, when viewed from the design specifications, the reason why the design item is required may be direct or indirect. The “direct” case is a case where it can be said that “the design item for satisfying the design specification X is α”. For example, if there is a design specification of “increasing the strength positively”, the design items will affect the performance of the product such as “select a material that uses metal instead of resin” or “provide reinforcing ribs”. Design items are required. As another example, when there is a design specification that “provides a texture on the design surface”, a design item “designate a texture treatment” is required. These are not design items required due to the presence of parts.

  On the other hand, in the case of “indirect”, the design specification and the design item are not directly related, but “when a certain part B is used, a certain design item is necessary for another part A. This is the case. For example, when the component A is a rear case of a mobile phone and the component B is a vibration motor, the design item “form a rib (for fixing the vibration motor) on the rear case” uses a component called a vibration motor. The vibration motor is a part necessary for satisfying the design specification of “enabling recognition of incoming calls by means other than voice”. As mentioned above, since the design specifications and the parts are associated with each other, it is possible to directly connect the design items to the design specifications. An operator who sets a necessary condition by associating the design specification “Enables recognition of incoming calls by means other than voice” as a necessary condition with the design item “Yes”. It becomes difficult to understand intuitively.

  Therefore, in the present embodiment, the design item extraction condition (required condition) is not limited to either the design specification or the component part, but can be defined for both in order to make it easy to understand intuitively. It is said. Furthermore, logical operations such as “AND” and “OR” can be set for the listed extraction conditions, thereby enabling more intuitive design item extraction conditions to be defined. It should be noted that the logical condition setting of the extraction conditions “AND” and “OR” is also possible in the component parts.

  In the example of FIG. 6, “design specification 1” and “value 1a” are entered in the “necessary condition” column. Note that “Item Spec” displayed in the “Type” field means that a design specification is associated as a necessary condition. That is, the design specifications “design specification 1” and “value 1a” are associated with “design item 1-1-2” via the dialog box shown in FIG. The design specifications or parts associated in this way are used as information when extracting design items from the design specifications or parts in the execution mode. When a component is associated as a necessary condition, “Part Type” is displayed in the “type” field.

  FIG. 9 is a diagram showing a method of registration of related know-how (S208). In the database, various know-how related to design work are stored in advance as a large number of documents. These documents are created during interviews with skilled designers or the like, or are accumulated while the design work is accumulated using this system. Here, an operation for associating a necessary one of these stored documents with each design item is performed.

  First, in FIG. 6, when the “Add” button in the “Related know-how” column is clicked, a dialog box for listing files in a folder storing documents that can be registered as related know-how is displayed as shown in FIG. Is done. These files are documents stored as general files such as Excel and Word (both are registered trademarks of Microsoft Corporation). The contents of these documents include patent information related to the design items, information on product defects, points to be noted in design work, and so-called know-how.

  When the operator selects an appropriate document from FIG. 9 and clicks the “Open” button, the selected document is registered in the “Related Knowhow” column as shown in FIG. In addition, if it is determined that the document once registered is unnecessary, it can be easily deleted. In addition, what is actually registered in this part is the path to the document displayed here, and when an operator clicks on one of the documents during the detailed design described later, it is linked to that document. The application starts automatically, and the document file is read and displayed in the application.

  When the property edit screen on the right side of FIG. 6 has been entered for the design item 1-1-2, clicking the “Close” button on the upper right displays the content entered here as “design item 1-1-2”. Saved as a property.

  As described above, design items and items other than design items can be changed from each other. For example, if “design item 1-1-1” displayed on the left side of FIG. 6 is selected with the mouse, a button “not to be simulated” (not shown) appears on the right side of the tree. Items are registered as design items. In other words, registering as a design item also means that each element constitutes a design flow diagram. On the other hand, when an item already registered as a design item is selected with the mouse, a “Remove from simulation target” button appears on the right side of the tree. Clicking this button removes the item from the design item. Such operations are appropriately performed to add, change, and delete each item, and register and cancel the design item.

  As described above, in FIG. 6, all items in the lowest hierarchy same as “design item 1-1-1” are registered as design items, and a square mark ( "Connection mark") graphically indicates that it has been registered as a design item. On the other hand, all items in the hierarchy above this are not registered as design items, and the square mark displayed in front of them (referred to as the “right-pointing arrow mark”) indicates that graphically. It shows.

  Since the item with the “connection mark” is a design item, it is also a simulation target. In this case, the “Remove from simulation target” button can be clicked. When this button is clicked, this item is no longer a simulation target (design item), and the mark displayed in front of that item is It changes to "Right arrow mark". However, even in this case, the information regarding the property entered in the dialog box on the right side of FIG. 6 for the item is saved without being deleted and can be used later. Conversely, when an item with a “right arrow mark” is selected, a “simulate target” button (not shown) can be clicked, and when this is clicked, this item is a simulation target, that is, a design item. Thus, the mark displayed in front of the item is changed to “connection mark”.

  When the “simulate design item extraction” button in the dialog box on the left side of FIG. 6 is clicked, the items to be simulated, that is, the design items are extracted from all the items, and the “parent” described above is extracted for each design item. With reference to “information”, a design flow diagram as shown in FIG. 11 is created (S209). This design flow diagram is experimental and not a final design flow diagram. The worker who performs the work in the construction mode checks whether or not there is any contradiction in the design flow diagram, and if a logical contradiction or the like is found, the parent information of the corresponding design item is corrected (S207).

  When the design specification is associated with the part (S205) and the design item is associated with the design specification or the part (S206), the system internally checks whether there is a contradiction between these associations (S210). . If a contradiction is found, the worker in the construction mode returns to the relevant association information and performs the work to resolve the contradiction.

  In the above example, the design specifications and the component parts are associated (S205) by marking the corresponding cells in the matrix in FIG. 5 with “O” (S205), and the necessary information is displayed in the “Required Conditions” column in FIG. The design specification or the component and the design item are associated with each other by the method of setting (S206). FIG. 35 shows an “association tool” for associating a design specification with a component (S205) and associating a design specification or a component with a design item (S206) in a manner different from the above example. Yes.

  The tool shown in FIG. 35 makes it easier to visually understand and easily execute the association between the design specification and the component (S205) and the association between the design specification or the component and the design item (S206). It is a thing. In this tool, various objects indicated by respective symbols are prepared in the object column. Attributes such as “design specifications”, “parts” (corresponding to component parts), and “design items” are set in advance for each object. An operator can create a relationship diagram between design specifications, component parts, and design items by placing the necessary objects in the editing area, entering names, and connecting the objects with lines. it can.

  The object list can be displayed by dragging and dropping an object in the object field to an arbitrary position in the editing area, or by placing the pointer at an arbitrary position in the editing area and right-clicking. By selecting a necessary object from among these, an arbitrary object can be placed at an arbitrary position. It is also possible to change the type of the object once arranged.

  When you add an object that has the attributes of “design specification”, “component”, and “design item”, the data of “design specification”, “component”, and “design item” is registered in the system. Then, the relationship between the design specification and the component, and the relationship between the design specification or the component and the design item are registered in the system from the connection of the objects.

  In the object column of FIG. 35, objects other than design specifications, components, and design items (“function”, “mechanism”, “value”, “memo”, and “OR”) are also prepared. These are not directly related to the association between the design specification and the component part (S205) and the association between the design specification or the component part and the design item (S206), but the operator has the relationship between the design specification, the component part, and the design item. You can work while expressing a logical connection when you define. In addition, using these objects makes it easier to understand the meaning of the diagram when the relationship diagram is viewed later.

  FIG. 36 is a diagram showing a relationship between design specifications, components, and design items created by using the association tool shown in FIG. 35 in the case of constructing a mechanism design support system for an open / close (foldable) mobile phone. Shows the part. In the example of FIG. 36, the specification “open / close detection function” is arranged at the “design specification” on the leftmost side. “Contact type”, “non-contact type”, and other methods considered as methods for realizing the specification of “open / close detection function” are arranged in the “function development” part.

  Here, looking at "contact type", the component "CASE-UPPER-F" requires the design item "Creating a pin for the open / close detection switch of CASE-UPPER-F". "CASE-LOWER-F" requires two design items: "CASE-LOWER-F open / close detection switch hole creation" and "CASE-LOWER-F open / close detection switch positioning shape creation" Is expressed.

  FIG. 37 shows a part of another example of the relationship diagram created using the association tool. This requires a certain function because the part A is required, the design item B is necessary to realize the function, and the part B is necessary to execute the design item B. It is shown that. Even if such a complicated relationship is created by using the association tool, it is easy to visually understand and the prospects are improved.

  Although the “construction mode” has been described in detail above, the work performed in the construction mode can be summarized as follows. In other words, when a certain business establishment develops and designs a mobile phone as a product, for example, when it is planned to support the design work of individual models in the future, an engineer who is familiar with mobile phone design is the first. From the interviews on what design items, what design specifications, and what parts are necessary, the results are shown in the design specifications via the screens of FIGS. , Registration of parts and design items, and association of design specifications and parts, design items and parts or design specifications, and registration of parent information and know-how materials for design items.

  In this way, the necessary information such as product design specifications, component parts, and design process is sufficiently registered in the construction mode, so that the same category in the “concept design” and “detailed design” of the following execution modes. It is possible to navigate a designer who actually designs a specific model of a product belonging to.

[Concept design]
Next, concept design, which is one of execution modes, will be described. FIG. 12 is a flowchart showing an outline of a work procedure in the concept design. When the “concept design” button is clicked on the screen of FIG. 1, a dialog box shown in FIG. 13 is displayed. In this dialog box, the existing orders are displayed in a list, and the procedure is to select an order (model) in charge of conceptual design from among them. In the example of FIG. 13, only one order named “Development-02” is displayed. On the other hand, if you do not have an order yet, you can create your own.

  When “Development-02” is clicked in the dialog box of FIG. 13, a “concept design information input screen” dialog box shown in FIG. 14 appears. This is a screen for performing work for determining design specifications (S1205). In general, design specifications are determined while listening to the opinions of the customer who requested the design and examining what functions or performance are required for the product to be developed.

  The dialog box of FIG. 14 shows each design specification necessary for the design of the mobile phone (“design specification 1”, “design specification 2”, “design specification 3” listed in the middle “design information item” column). ,...), And the contents, that is, the design value, that is, the design value is input in the form of filling in the blank of “design value”.

  However, if similar models have been developed in the past in order to simplify the input work for each design specification and give design tips for inexperienced designers, design of that model The value can be diverted. When diverting part of the design values of a model designed in the past, select the registered model by clicking the down arrow on the right side of the input box “Diverted model name” in the dialog box of FIG. can do. FIG. 15 shows a state in which the design value of “model-01” is displayed in the “reference value” column by selecting the model “model-01”.

  In FIG. 15, “value 1a” or the like is entered in the “reference value” and “design value” fields, but a specific numerical value or the like is actually entered. For example, if the “design specification” is the size of the window for the liquid crystal display panel, the size is input in a predetermined length unit, and the “design specification” must be passed by dropping in the drop test. If it is "height", a height value such as 5 meters is input. The concept designer determines each design specification of “development-02” to be newly developed while referring to the design value of each design specification of “model-01”. For example, when designing the same design specifications for many parts even if the models are different, such as when designing a mobile phone, many of the design specifications created in the past can be diverted. The working time can be shortened as compared with the case of creating.

  As explained earlier in the construction mode, since the relationship between each design specification and the component is defined and registered in the database, when the design specification is determined, the component based on the design specification is stored in the database in advance. It can be automatically extracted from the list of registered parts (S1206). FIG. 16 shows a state in which all design specifications are input in the dialog box shown in FIG. At this stage, when the button “Register component” shown in the lower left of the dialog box in FIG. 16 is clicked, the screen of the component table shown in FIG. 17 is displayed on the display.

  In FIG. 17, information on one component is described in one line. As information to identify each part, the fields of “Unit name”, “Sub unit name”, “Part name”, “Part type”, “Part number”, “Cost”, “Material” and “Weight” are used here. Provided. However, information is not necessarily described in all these fields. Also, in the dialog box shown in FIG. 17, all the parts shown here have unit names “main body”. The concept designer decides the parts required for the model to be designed this time while adding, deleting, and changing the displayed parts according to the model currently designed, and displays them in the dialog box shown in FIG. Register at

  In addition, a function for displaying all the parts registered in the construction mode is provided so that addition, change, deletion, etc. of the component parts can be easily performed. When the button “all parts list” is clicked in the dialog box shown in FIG. 17, all parts registered in this system are displayed as shown in FIG. Although not clearly shown in FIG. 18, among all the displayed parts, for the component part selected in the model “Development-02” to be designed this time, the entire line is displayed in a different color from the other parts. Is done. Therefore, when the “all parts list” in FIG. 18 is displayed, it can be seen at a glance what is selected in the component table of FIG. 17 and what is not. To add a new item that has not been selected, click on the row and click the “Register” button in FIG. 18 to add the part to the component parts table in FIG.

  On the other hand, if there is a part that the concept designer has determined to be unnecessary for the model among the parts automatically selected by the system based on the information set in the construction mode, the component parts table of FIG. Select an unnecessary part row and click the “Delete” button. As a result, the part is deleted from the component parts table of FIG. 17, and when the entire parts list of FIG. 18 is displayed thereafter, the row of the deleted part changes to a non-selected color.

  As described above, when design specifications and components are determined, design items necessary for designing this model can be extracted based on information set in the construction mode (S1208). When the “Flow generation” button in FIG. 17 is clicked, the system internally extracts design items for this model, and the above-mentioned “parent information” set for each design item is prepared in advance. Is supplied to an algorithm for generating a flow diagram, and a design flow diagram is generated (S1209).

  FIG. 19 is an example of a design flow diagram generated in this way. In this design flow diagram, square marks such as “design item 1-1-1” below represent one design item. The horizontal axis (toward the right) shows the passage of work time. Accordingly, when two design items (for example, “design item 1-1-1” and “design item 2-1-1”) are compared, the time on the right side (design item 2-1-1) is longer. Will run slower. Moreover, the thing with the same position of a horizontal axis represents that it can perform in parallel. For example, in FIG. 19, any of the design items 1-1-1, 3-1-1, 6-1-1 can be executed first, and if necessary, a plurality of design work can be performed. It is also possible to share the work with other workers.

  From FIG. 19, the following can be understood. First, when the design item 1-1-1 is completed, the design item 1-1-2 and the design item 2-1-1 can be executed. When the design item 3-1-1 is completed, the design item 1-1-1 is completed. Items 4-1-1, 4-2-1 and 5-1-1 are ready to be executed. In order to execute the design item 2-2-1, it is sufficient that the design item 2-1-1 is completed. However, in order to execute the design item 2-2-2, the design item 2-1 Both 1 and design item 4-1-1 need to be completed. In order to execute the design item 6-1-2, the design items 4-2-1, 5-1-1, and 6-1-1 must be completed. In this way, by graphically expressing the relationship between each design item, the worker can visually grasp the progress of the overall design work and what design items can be worked on at the present time. Can do.

  The concept designer first looks at the generated design flow diagram to check whether there is a problem in the design item itself (S1210), corrects the problem (S1211), and if there is no problem, (S1212), and if there is a problem, the design flow diagram is corrected manually (S1213).

  Further, as described above, when the design flow diagram of FIG. 19 is generated, only the information (parent information) of the parent design item is defined for each extracted design item, and an appropriate design flow diagram is generated. Another feature of this system is that it can be generated.

  When the concept design is completed, an operation to notify the system to that effect is performed by “task issue” shown in FIG. This is the same as the dialog box shown in FIG. 13. Here, when you place the mouse arrow on the line “Development-02” and right-click, a button “Issue Task” is displayed. Click this button. To do. Then, this task is transferred from the conceptual design to the detailed design, and as shown in FIG. 21, the task disappears from the “order selection screen” of the conceptual design, and the task is shifted to the detailed design described next.

[Detailed design]
Next, detailed design, which is one of execution modes, will be described. In this detailed design, for example, when a worker actually executes each design item on a CAD terminal different from this system, the work performed by the worker is navigated.

  FIG. 22 is a flowchart showing an outline of the entire detailed design. As a procedure for detailed design, enter the user name and password on the login screen (not shown) and click the “OK” button until the dialog box shown in FIG. 1 is displayed. This is the same as “concept design”. When the “detailed design” button is clicked in the dialog box of FIG. 1, the dialog box of FIG. 23 is displayed. This dialog box is for “order selection” and corresponds to the dialog box shown in FIG. 13 in the case of conceptual design.

  The task “development-02” exists in the dialog box of FIG. 23. In the dialog box of FIG. 20 described in connection with the concept design, the task is issued for the detailed design, and the task is changed from the concept design to the detailed design. Based on the transition.

  When the “development-02” portion is clicked in the dialog box of FIG. 23, each design item of the detailed design that must be designed for this “development-02” is displayed in a list as shown in FIG. 24 (S2205). . Each design item displayed in a list here corresponds to each design item shown in the design flow diagram of FIG. The operator who performs the detailed design can easily know the design items that the user must perform the design work by looking at the list shown in FIG.

  In the list of FIG. 24, fields of “part name”, “part name”, “design item name”, “state”, “designer”, and “date and time” are prepared. Here, the “part name” field indicates to which part the design item is the work. The “part name” field indicates which part the part belongs to. The “status” field is provided to indicate whether or not the design work can be started. In the “designer” field, the person in charge of the design or the name of the person in charge of the design is displayed (here, it happens to be “unknown”). In the “date and time” field, the date and time when the design item becomes “designable” or the date and time when the design is completed is displayed.

  Whether or not the work for a certain design item can be started depends on whether or not the work for a required design item has been completed before the design item, as described above with reference to FIG. The three design items 1-1-1, 3-1-1, and 6-1-1 that are “designable” in FIG. 24 are the first items that are located on the leftmost side in the design flow diagram of FIG. It corresponds to three design items that can start work. The worker may start from any of these three design items, and the computer acquires the design item selected and clicked by the worker, and the work is being performed.

  Although it is difficult to understand from FIG. 24, in the system of this embodiment, the display method and color are changed according to the contents of the “status field” so that it can be easily distinguished visually. In other words, design items whose “state” field is “designable” are usually displayed in blue, design items whose “design is not possible” are displayed in gray, and design items whose work has been completed are normally displayed in black. The design items that are under way by access from other computers are usually displayed in red.

  In the dialog box of FIG. 24, when the button “display design flow” below is clicked, a design flow diagram almost the same as that shown in FIG. 19 can be displayed (S2206). Thus, the operator can easily refer to the design flow diagram as necessary. In this case, the three design items that are currently “designable” in the displayed design flow diagram are blinked and displayed in a different color from the other design items. Thereby, the worker can grasp at a glance the current situation in the entire work process.

  In FIG. 24, when one of the three design items capable of starting the design work is clicked, the status of the clicked design item is started on the system of this embodiment (S2207). . If “top design item 1-1-1” is selected here, a detailed design screen for this design item shown in FIG. 25 appears.

  In the area on the left side of FIG. 25, the entire design process is displayed as a tree, “design item 1-1-1” under development is highlighted, and other design items are displayed in the list of FIG. Similar to the status field, it is displayed separately by display and color. In the area on the right side of FIG. 25, various information regarding the design item 1-1-1 is displayed. For example, “Development-02”, which is the name of this development project, is displayed in the “Development model name” column. The name of the operator who performed the conceptual design is displayed in the “concept designer” column (the blank in the example of FIG. 25), and the “item function” column indicates the function realized by this design item. Explanation is displayed.

  Although it is possible to newly add information at this stage on the screen of FIG. 25, FIG. 25 basically shows the contents to be performed as the work of this design item to the worker who performs the detailed design. It is for presenting information for guidance. The worker performs the actual design work while confronting the terminal of the CAD system and the like while following the navigation by this system.

  In the “check item” column of the dialog box of FIG. 25, management items that the worker must work on are listed in this design item. Each time the worker completes the work of the management items listed here on the CAD, the operator puts a check mark in the check box on the left side of the management item (S2208, S2209). The design item cannot be completed unless all management items are checked in the program (S2210). With this kind of devise, even inexperienced workers who do not know what items to consider in the design items can reliably perform the necessary work, such as work leakage Can be prevented. The management item can be set in the construction mode in the system of this embodiment.

  Further, in the “Viewer” area on the right side of FIG. 25, an image of a portion related to this design item is displayed. This image data is obtained by extracting and displaying a corresponding portion from CAD design data. As a result, the worker can visually grasp to which part of the developed model the work he / she is currently performing corresponds.

  The operator performs design work on the CAD system in accordance with the instructions of the design navigation system, but both are generally independent. However, if the program for the CAD system and the program for the design navigation system are switched each time, or if both systems are located at separate locations, it is necessary to move from one to the other. Therefore, if the design screen on the CAD system can be referred to on the design navigation system as in the system of the present embodiment, the work efficiency is improved.

  The information listed in the “Knowledge list” column in the middle of FIG. 25 is information on “related know-how” registered in the above-described construction mode (see FIG. 10). The “Knowledge List” column contains documents with file names in general formats such as Excel and Word. These files are used for design work such as know-how and related patents related to this design item. Information useful for the above is described, and the operator can refer to it as necessary (S2212).

  FIG. 26 shows, as an example, an image that appears when a document “design concept” included in the “knowledge list” of FIG. 25 is clicked. This “design concept” is stored as an Excel file. When this document is clicked, Excel is automatically activated, and a file named “design concept” is automatically read into Excel. It is a mechanism that is displayed as follows. In this way, the designer can instantly refer to the information registered in the knowledge list while performing the work, so even those who have little experience or knowledge of the design work can know the know-how described in these documents. It is possible to carry out design work efficiently and at a certain level or higher while referring to information.

  In addition, if there is a track record of actual design work or a point that the design engineer noticed while performing the actual design work, a new one can be referred to later workers. It can be registered in the design item acquired as know-how (S2213). Furthermore, in order to grasp the relationship between the current design item and other design items graphically, a design flow diagram can be displayed as appropriate (S2214).

  FIG. 27 is similar to FIG. 25, but FIG. 27 is listed in “Check Items” while operating CAD software running on a terminal different from the terminal on which this system is running, for example. The design work is performed on each management item, and the operation of clicking the check box of the corresponding management item is repeated each time one item is finished, and all the management items are checked.

  In FIG. 27, the “check item” field is clicked by the operator to add a check mark. However, depending on the design item, the operator must input some numerical value or wording from the keyboard or the like. There is also. In such a case, the check box may be clicked only after the numerical value is input.

  Further, when setting management items in the construction mode, for example, “3 only”, “3 or more”, “3 or less”, “3 ± 1” can be added to the input numerical values. These represent a state in which only 3 can be input, a state in which only 3 or more numerical values can be input, a state in which only 3 or less numerical values can be input, and a state in which only 2 to 4 numerical values can be input. If a numerical value outside the limit is entered for a management item with such restrictions, the management item cannot be checked, and as a result, as a rule, do not proceed. is there. However, depending on the development status of a new product, it may be necessary to input a numerical value that is outside the limit determined in the construction mode. To deal with such a case, create a document in Word or Excel that describes the reason why you had to enter a numerical value outside the limit, and register it in a specific column (not shown) on the detailed design screen. On the condition that this is done, a check mark may be added to the management item.

  When all the management items shown in “Check Items” in FIG. 27 are checked, the “Design Complete” button at the bottom of FIG. 27 can be clicked. In this way, this system navigates the worker and informs the worker through the computer what kind of design work is required at each stage. But you almost never forget to design the necessary items.

  Here, when the “design completed” button is clicked (S2211), the dialog box shown in FIG. 27 is closed and the dialog box shown in FIG. 28 is displayed. This dialog box is similar to the dialog box of FIG. 24, but with some changes. That is, in the dialog box of FIG. 28, the “state” field of the design item 1-1-1 is changed to “design completed”, and accordingly the “state” field of the design item 1-1-2 is “design ready”. The display is normal.

  Next, the “return” function (S2215) will be described. This function is a function that allows a user to return to a desired design item with a simple operation when he / she wants to redo the previous design item after the work in the detailed design has progressed to some extent. FIG. 29 is a diagram for explaining the “return” function. FIG. 29 shows a dialog box of a list of design processes. As can be seen from this “state” field, some design items displayed here are already completed (“design completed”). There are some that can be designed at the present time (those that are “designable”).

  At this time, it is assumed that design work is being performed for the design item 2-2-2 in which the “state” field is “designable”. FIG. 30 is a dialog box showing a state where the design work of the design item 2-2-2 is being performed. Here, it is assumed that it is necessary to redo the design item 1-1-1 for some reason, and the design work of the design item 1-1-1 is redone using the rework function. In that case, click “design item 1-1-1” in the tree display on the left side of FIG. 30 to select it and click the “NG” button. Then, a confirmation screen shown in FIG. 31 is displayed. Here, a “Yes” button is clicked to display a new design process list screen shown in FIG. As can be seen, one design item 1-1-1 is newly added, and two identical design items 1-1-1 are displayed. Looking at the “state” field of the design item 1-1-1 added here, it can be seen that “design is possible”.

  FIG. 33 shows how the design flow diagram has changed before and after using the rework function. In the design flow diagram of FIG. 33A before reworking, the design item 2-2-2 is displayed as a design item that can be executed at the present time. On the other hand, in FIG. 33B after reworking, the design item 2-2-2 is displayed in a color indicating that it has already been completed, and instead the design item 1-1-1 is displayed. It is displayed as a design item that can be executed at the present time. Along with this, it is necessary to redo the work for the design items 1-1-2, 2-1-1, 2-2-1. For example, when the reworked design item 1-1-1 is completed, FIG. In the design flow chart of FIG. 33 (b), design items 1-1-2 and 2-1-1 that can be subsequently designed are displayed as executable states. The design work is re-executed by the rework function, and when the design work is completed, the design flow diagram is updated (S2217).

  The designer proceeds with the design work while repeating the work described above. Finally, when all the design items are completed and the “state” field of all the design items becomes “design completed” as shown in FIG. 34A, the button “end declaration” can be clicked. (S2218, S2219). When this button is clicked and the “OK” button is clicked on the confirmation screen shown in FIG. 34B, the order “Development-02” disappears from the order selection screen, as shown in FIG. 34C. . This completes the detailed design. As another example, when all the “status” fields are “design completed” on the screen of FIG. 34 (a), a message to that effect is sent to the concept designer by e-mail. It may be possible to look at the contents of the detailed design and approve the contents before finishing the detailed design.
