Description

  The present invention relates to CAD design, and more particularly to a design support program, a design support method, and a design support system for presenting information necessary for selecting products and parts to be used for design in cooperation with a CAD database and a purchase database. .

  In product design, CAD (Computer Aided Design) design using a computer is generally used. In CAD design, detailed design is divided into parts from the overall concept design, followed by design flow such as assembly design. At this time, using standard parts as much as possible, the design and product costs can be kept as low as possible. Done. For this reason, the CAD system stores already designed parts data and purchased parts data as standard parts in a database and uses these standard parts. In addition, based on parts stored in a database, similar data is designed by changing those data.

  In product design, when selecting a part in order to use a standard part, a designer searches a database and displays it on a display of a CAD system to check whether the part is a desired part. In addition, some standard parts are listed as candidates for selection, and when you want to use the parts with the highest usage amount or the parts with the lowest cost, search the purchasing database to find the usage amount and cost. I was going to investigate.

As a technique related to these, a design method capable of registering and searching for standard parts has been proposed. In this method, when registering standard parts, design information that defines the basic structure, attribute values that define detailed specifications, and shape feature data that represents shape features are associated and registered in a database. A method of searching for a standard part that matches the input data from a database has been proposed (for example, Patent Document 1).
Japanese Patent Laid-Open No. 9-179892

  As described above, in CAD design, a database storing standard parts is provided, and the parts to be used are searched from the database and displayed on the display, and it is confirmed whether or not the parts are obtained while checking the dimensions. In addition, in order to check the usage amount and cost, the CAD system is once removed and the purchase system is accessed and checked. In addition, graphs were made using other systems to see trends in usage. For this reason, it took a lot of time to select the parts to be used, and the design was not necessarily efficient.

  The method proposed in Patent Document 1 can search for standard parts in a short time, and is considered to contribute to improvement in design efficiency. However, information to be given as attribute values varies greatly depending on the type of component to be registered, and no consideration is given to which part is called by what name and registered as an attribute value. In addition, it does not present information such as how much the standard parts are purchased and what the unit price is.

  In the present invention, CAD data of a product or part to be registered and attribute information determined corresponding to the product or part are registered in association with each other, and the CAD data of the product or part to be searched for at the time of use is determined. It is an object of the present invention to provide a design support program, a design support method, and a design support system that can be searched by attribute information and can obtain purchase record data in a seamless cooperation with a purchase database.

The design support program, the design support method, and the design support system of the present invention are configured as follows.
(1) 1st invention 1st invention is matched and registered with the attribute information defined in the registration of CAD data of a product or a part, a search is enabled by this attribute information, and the searched product or part This is a design support program that acquires purchase results data of products or parts selected from among them and displays them in a graph.

  The principle will be described with reference to FIG. The first invention is a CAD terminal connected via a network to a CAD server having a CAD database and a purchasing server having a purchasing database. The CAD terminal programs are a CAD data registration procedure 10, a CAD data search procedure 20, and a purchase data search procedure. 30 and purchase result display procedure 40. These individual components will be described.

  The CAD data registration procedure 10 registers CAD data of a product or a part used for the product in the CAD database in association with attribute information defined for the product or part. For example, if the part to be registered is a gear, CAD data of the gear is registered in association with attribute information defined for the part called gear. If the part to be registered is a pulley, the attribute information is determined for the part called a pulley.

  The CAD data retrieval procedure 20 retrieves a corresponding product or part from the CAD database by inputting a part or all of the registered attribute information.

  The purchase data search procedure 30 searches the purchase database for purchase results of products or parts selected from the products or parts searched in the CAD data search procedure 20. At this time, the search is performed under the specified search condition, and the purchase result information which is the search result is stored. The designated search condition is, for example, a purchase period.

The purchase record display procedure 40 displays the stored purchase record as a graph under specified conditions. The designated condition is, for example, a graph type such as a bar graph or a pie graph.
(2) Second invention In the second invention, the CAD data registration procedure according to the first invention provides a registration template corresponding to the inputted identification information by inputting the identification information for identifying the product or part to be registered. indicate. Then, the information entered in the displayed registration template is registered in association with the CAD data of the product or part. The information input to the registration template is product or part attribute information.
(3) Third invention According to a third invention, the CAD data search procedure according to the first invention is a search template corresponding to the input identification information by inputting the identification information for identifying the product or part to be searched. Is displayed. Then, a search is performed based on the information input in the displayed search template. The information input to the search template is product or part attribute information.

  The design support program further includes a CAD data registration unit 161, a CAD data search unit 162, and a purchase data search unit 163. The CAD data registration unit 161 includes a registration template extraction processing unit 161-1 and a CAD data registration processing unit 161-2. The CAD data search unit 162 is a search template extraction processing unit 162-1 and a CAD data search processing unit 162-2, and the purchase data search unit 163 is a purchase data search processing unit 163-1 and a purchase record data graphing processing unit 163-2. Consists of. The function of each part of these design support programs will be described next. It is assumed that CAD data of a product or part to be registered is stored in the CAD data storage unit 141.

  The registration template extraction processing unit 161-1 acquires the identification information of the product or part to be registered input from the keyboard 132 by the operator, specifies the registration template with reference to the identification information determination table 143 based on this identification information, The specified registered template is extracted from the registered template storage unit 144 and displayed on the display 131. Then, the attribute information input from the operator for each item of the attribute information of the displayed registration template is acquired.

  The CAD data registration processing unit 161-2 accesses the CAD server 200 via the network 400, and receives the attribute information acquired by the registration template extraction processing unit 161-1 and the CAD data stored in the CAD data storage unit 141. The data is transmitted to the CAD server 200, and these are associated and registered in the CAD database 201.

  The search template extraction processing unit 162-1 acquires identification information for identifying CAD data of a search target product or part input by an operator, and refers to the identification information determination table 143 based on this identification information to search the search template. The specified search template is extracted from the search template storage unit 145 and displayed. And the information (namely, attribute information) input from the operator to the search item of the displayed search template is acquired.

  The CAD data search processing unit 162-2 searches the CAD database 201 of the CAD server 200 via the network 400 using the attribute information acquired by the search template extraction processing unit 162-1 as a search key, and displays the corresponding product or part diagram. The attribute information including CAD numbers and names and CAD data are taken into the CAD data storage unit 141, and the chart numbers, names, and other attribute information are displayed as a list on the display 131.

  The purchase data search processing unit 163-1 acquires the figure number selected by the operator from the products or parts displayed on the display 131 and the search condition input by the operator, and uses the figure number and the search condition as a search key. The purchase database 301 of the purchase server 300 is searched via the network 400. The corresponding purchase record data is displayed as a list on the display 131 and stored in the purchase record data storage unit 142. Further, the purchase data search processing unit 163-1 accepts a figure number directly input by the operator, and enables the search similarly.

  The purchase record data graphing processing unit 163-2 acquires the graphing conditions input by the operator, graphs the purchase record data stored in the purchase record data storage unit 142, and displays the graph on the display 131.

  This is the end of the description of the design support program 160. Next, the identification information determination table 143 will be described. The identification information determination table 143 is a table for specifying a registration or search template corresponding to identification information input by an operator when registering or searching for CAD data. As shown in FIG. It is the table which matched the name of components, ID of a registration template, and ID of a search template. Here, the identification information is a symbol of the upper three digits of the figure number. In FIG. 4, the name is gear corresponding to the identification information CA8, and the ID of the registered template and the ID of the search template are set.

  Next, an example of a registered template will be described with reference to FIGS.

  FIG. 5 shows an example of a list format of registration templates, and FIG. 5A shows an example of a registration template for gears that are machine parts. For example, when the operator inputs CA8 to register a gear, the design support program 160 refers to the identification information determination table 143 and extracts and displays it from the registered template storage unit 144 based on the registered template ID of the gear. FIG. 5A shows an example in which the operator inputs data to each item (becomes an item of attribute information) in the displayed registration template. In this example, the CA 888 of the figure number is entered by the design support program 190 adding a serial number to the upper three digits of the figure number entered by the operator as identification information, the name is entered from the correspondence table described above, and the subsequent numbers The operator inputs the items. The registered template shown in FIG. 5A includes a drawing number, name, inner diameter, tolerance (tolerance for inner diameter), outer diameter, tolerance (tolerance for outer diameter), width, tolerance (tolerance for width), number of teeth, etc. It is an item. FIG. 5B similarly shows an example of a pulley registration template.

  FIG. 6 shows an example of a card type registration template. 6A refers to the identification information determination table 143 based on the identification information input by the operator as in FIG. 5, identifies the ID of the registration table, and extracts the registration template from the registration template storage unit 144. Then, each item of the registration template is sequentially displayed for each item. As described with reference to FIG. 5 (a), the design support program 160 fills in and displays the first and second item card numbers and name cards, and the operator inputs the third item card. Since the next card is not displayed unless it is input, there is no omission of input of attribute information. FIG. 6B shows an example of a pulley card type registration template.

  The search templates are substantially the same, for example, with some differences in items that can be searched out of the registered templates being set.

  The registration template storage unit 144 stores the format of the registration template shown in FIG. 5 in association with the registration template ID set in the identification information determination table 143. The same applies to the search template storage unit 145.

  Next, examples of items listed as attribute information are shown in FIG. Here, examples of gears, straight pulleys, one-side flat pulleys, both-side flat pulleys, toothed belts, and flat belts, which are mechanical parts, are shown. A registered template in which items of attribute information are set for each component is created and stored in the registered template storage unit 144 in association with the registered template ID. The same applies to the search template.

  Next, the processing flow of the CAD terminal 100 will be described with reference to FIGS. Here, in the CAD data registration and search, the registration template for specifying attribute information and the identification information input by the operator for extraction of the search template use the above three-digit symbol of the figure number. FIG. 8 shows a processing flow of CAD data registration. First, identification information input from the keyboard 132 by the operator is acquired. Subsequently, the registered information ID is specified with reference to the identification information determination table 143 based on the acquired identification information. A registered template is extracted from the registered template storage unit 144 based on the registered template ID. Then, this registered template is displayed on the display 131 (S110, S130).

  Subsequently, the attribute information input by the operator in the displayed registration template is acquired. Then, it is checked whether or not the acquired attribute information is input for all items set in the registration template. If there is an uninput item, the user is prompted to input the item, and the attribute information input again is acquired and checked. If it is confirmed that all items are input, the attribute information and CAD data are transmitted to the CAD server 200 and registered in the CAD database 201 in association with each other (S140-S170).

  Next, the processing flow of search processing will be described. In FIG. 9, the identification information of the search target product or part input from the keyboard 132 by the operator to search for CAD data is acquired. The corresponding search template ID is specified with reference to the identification information table 143 based on the acquired identification information. The search template storage unit 145 is referred to by the search template ID, and the search template is extracted and displayed on the display 132 (S210-S230).

  The attribute information input by the operator is acquired from the displayed search template, and the CAD database 201 of the CAD server 200 is searched via the network 400 using the acquired attribute information as a search key. The retrieved attribute information and CAD data of the product or part are fetched and stored in the CAD data storage unit 141. Then, a list is created based on the attribute information and displayed on the display 132 (S240-S260).

  The figure number selected by the operator from the list is acquired, and further the search condition for the purchase record data search entered by the operator is acquired. The purchase database 301 of the purchase server 300 is searched based on the figure number and the search condition (S270-S290).

  The purchase result data of the search result is captured and stored in the purchase result data storage unit 142. Subsequently, the graphing conditions input by the operator are acquired, and the purchase record data in the purchase record data storage unit 142 is graphed under the graphing conditions. Then, the graphed purchase record data is displayed on the display 132 (S300-S320).

  The description of the processing flow is finished as described above, and an example of search results and graphing processed in this flow will be described next.

  FIG. 10 shows an example of the search result of CAD data. This indicates that the operator inputs CA8 as identification information, specifies the outer diameter of 8 mm in the search template, and searches, and as a result, three gears CA888, CA825, and CA811 are searched.

  FIG. 11 shows an example of a search result of purchase record data. This is an example in which the operator designates CA888 and CA805 having the same inner diameter among the three gears shown in FIG. 10, and designates the purchase results for the most recent half year as the search condition. The search results are arranged in ascending order of unit price.

  An example of graphing the purchase record data is shown in FIG. This is specified to search the purchase results of the most recent half-year of gears having an inner diameter of 1 mm to 8 mm and to graph the results by bar graphs by inner diameter.

  In the description of the above processing flow, the identification information input when registering or detecting CAD data has been described using the example of the upper three digits of the figure number. However, the identification information may be a name. A list of names may be displayed at the time of input of identification information and selected from the list.

  In addition, the operator may input attribute information to the registration template from the keyboard 132 to each item of the registration template. In addition to this keyboard input, the CAD data is graphically displayed to correspond to the item of the registration template. The graphic element to be specified may be specified using a mouse or the like (not shown), and the dimension value may be acquired and input.

  Further, CAD data search results may be displayed in a list, and products or parts designated by the operator may be displayed graphically. By doing in this way, the detailed part of the searched product or part can be confirmed.

  In addition to the above examples, the following additional notes are disclosed.
