  However, the structure may be different even for parts used in the same location. In such a case, it is not easy to standardize the parts, or it is necessary to prepare a large amount of standardized graphic data. For this reason, there is a case where it is not possible to employ a technique for replacing graphic data with data corresponding to a part to be designed as described above.

  An object of this invention is to provide the technique which can perform flexible component design easily.

  In order to solve the above problems, the present invention employs the following means. That is, the present invention sets, in a design support apparatus, structure standardized data acquisition means for acquiring structure standardized data representing the structure of a design part obtained by dividing a part into design units, and design item data necessary for designing the design part. Design item data setting means, and structure standardization data generation means for correcting the structure standardization data acquired by the structure standardization data acquisition means based on the design item data set by the design item data setting means .

  By adopting such a configuration, it is possible to obtain structural standardized data representing the structure of a design part obtained by dividing a part into design units, and modify the design part based on design item data necessary for designing the design part. Shape data representing the shape of is generated. That is, since the structure standardized data prepared for each design part is used, the shape of the part is represented by the combination of the structure standardized data, and the data that is standardized for each part as before is used. It is possible to cope with the design of parts with various shapes. In addition, since the structure standardized data can be corrected, flexible part design can be easily performed.

  In the design support apparatus, the structure standardized data acquisition unit acquires the structure standardized data corresponding to the design part of the part to be designed based on the correspondence relationship between the part, the design part, and the structure standardized data. And

  With this configuration, the correspondence between parts, design parts, and structural standardization data is clarified, so it is possible to easily obtain structural standardization data corresponding to the design part of the design target part. It becomes.

  In the design support apparatus, a part selecting unit that selects a part to be designed from a list of parts, and a design part selecting unit that selects a design part to be designed from a list of design parts constituting the part selected by the part selecting unit. The structure standardized data acquisition unit selects necessary structural standardized data from a list of structure standardized data representing the structure of the design site selected by the design site selection unit.

  With this configuration, a list of parts, design parts, and structure standardized data is used and structural standardized data corresponding to the design part of the part to be designed is selected. Thus, it is possible to perform appropriate support when the operator performs an operation of selecting the structure standardized data.

  In the design support apparatus, the structure standardized data acquisition unit selects the structure standardized data that satisfies the performance requirements of the parts.

  By adopting such a configuration, the structure standardized data that does not satisfy the performance requirements of the parts is excluded from the selection target, and thus the structure standardized data is appropriately selected.

Further, there are a hard disk, a ROM (read only memory), and the like as a recording medium fixed to the computer.

  According to the present invention, efficient component design can be performed.

  A design support apparatus according to the best mode for carrying out the present invention (hereinafter referred to as “embodiment”) will be described below with reference to the drawings. In addition, the structure of the following embodiment is an illustration and this invention is not limited to the structure of embodiment.

FIG. 1 shows a configuration diagram of a design support system according to an embodiment of the present invention. A design support system 10 shown in FIG. 1 supports the design of each part constituting a vehicle.
Aided Design) device 100 and server 200. The CAD apparatus 100 includes a selection unit 102, a display unit 104, an operation unit 106, a structure standardized data DB 108, a parameter setting unit 110, a structure standardized data correction unit 112, a design check item DB 114, and a confirmation unit 116. On the other hand, the server 200 includes a design information DB 202 and a design information reading unit 204.

The CAD device 100 and the server 200 are computers having a CPU, a memory, a hard disk, a communication interface, and the like. The CAD device 100 and the server 200 provide functions as the CAD device 100 and the server 200 by executing a computer program loaded in the memory by the CPU. Since the computer configuration itself is widely known, the description thereof is omitted.

  Although not clearly shown in FIG. 1, the execution results of the CAD device 100 and / or the server 200 or both of them are transmitted and displayed to the user, and the user's input is read, and the CAD device 100 or the server 200 or Such terminals that transmit to both may be provided for user operations.

  The design support system 10 supports the design of parts that constitute a vehicle. FIG. 2 is a diagram illustrating an example of a component. The part shown in the figure is a frame part (pillar garnish) 300 between a windshield of a vehicle and a front door. The pillar garnish 300 includes five design parts (a door opening part 301, a windshield matching part 302, a general part 303, a ceiling matching part 304, and an instrument panel matching part 305) divided into design units.

  The design information DB 202 in the server 200 stores design information that is information indicating a correspondence relationship between a part, a design part constituting the part, and structure standardized data representing the structure of the design part. FIG. 3 shows an example of design information. The design information includes a parts list shown in FIG. 3A, a design part list shown in FIG. 3B, and a structure standardized data list shown in FIG.

  The parts list is composed of names of parts that can be designed and link destination information to a design part list that is a list of design parts constituting the part. The design part list is configured for each part that can be a design target. To the structure standardization data list that is a list of the structure standardization data representing the name of the design part constituting the part and the structure of the design part Link destination information. The structure standardized data list is configured for each design part, and includes a name of the structure standardized data representing the structure of the design part and a template that is identification information of the structure standardized data.

  On the other hand, the structure standardized data DB 108 in the CAD device 100 stores the structure standardized data in association with the template. The design support system 10 uses the design information and the structure standardized data to generate shape data representing the shape of each design part constituting the part to be designed. The design check item DB 114 records design conditions to be satisfied for each part, for example, dimensions of specific parts, distances between specific parts, and the like.

  FIG. 4 shows a flowchart of the operation of the design support system 10 according to the embodiment of the present invention. The selection unit 102 in the CAD device 100 instructs the design information reading unit 204 in the server 200 to read the parts list. In response to this instruction, the design information reading unit 204 reads a parts list from the design information DB 202 and outputs it to the selection unit 102 in the CAD device 100.

  The selection unit 102 generates a screen corresponding to the input component list and displays it on the display unit 104. The worker recognizes a component list, in other words, a component that can be a design target, on the screen displayed on the display unit 104. Then, the operator uses the operation unit 106 to perform an operation of selecting any part included in the parts list as a design target. The operation unit 106 outputs an operation signal corresponding to this operation to the selection unit 102. Based on this operation signal, the selection unit 102 selects any component included in the component list, and outputs the selection information to the design information reading unit 204 in the server 200 (S101).

The design information reading unit 204 identifies the selected part based on this selection information. Furthermore, the design information reading unit 204 reads a design part list that is a list of design parts constituting the selected part from the design information DB 202 based on the link information in the part list corresponding to the selected part. For example, when the pillar garnish shown in the parts list shown in FIG. 3A is selected as the design target, the design information reading unit 204 uses the link destination information corresponding to the pillar garnish to design the part that forms the pillar garnish. The design part list (design part list #a) which is a list of is read from the design information DB 202. Furthermore, the design information reading unit 204 outputs the read design part list to the selection unit 102 in the CAD device 100.

  The selection unit 102 generates a screen corresponding to the input design part list and displays it on the display unit 104. The operator recognizes the design site list, in other words, the design site constituting the part to be designed, on the screen displayed on the display unit 104. Then, the operator uses the operation unit 106 to perform an operation of selecting any design part included in the design part list as a design target. The operation unit 106 outputs an operation signal corresponding to this operation to the selection unit 102. Based on the operation signal, the selection unit 102 selects any design part included in the design part list, and outputs the selection information to the design information reading unit 204 in the server 200 (S102).

  The design information reading unit 204 identifies the selected design part based on this selection information. Furthermore, the design information reading unit 204 is a structure standardization data that is a list of structure standardization data representing the structure of the design part selected from the design information DB 202 based on the link information in the design part list corresponding to the selected design part. Read the data list. For example, when the door opening part shown in the design part list shown in FIG. 3B is selected, the design information reading part 204 represents the structure of the door opening part by the link destination information corresponding to the door opening part. A structure standardized data list (structure standardized data list #b), which is a list of structure standardized data, is read from the design information DB 202. Further, the design information reading unit 204 outputs the read structure standardized data list to the selection unit 102 in the CAD device 100.

  The selection unit 102 generates a screen corresponding to the input structure standardized data list and displays it on the display unit 104. The worker recognizes the structure standardized data list, in other words, the structure standardized data representing the structure of the design part to be designed, on the screen displayed on the display unit 104. Then, the operator uses the operation unit 106 to perform an operation of selecting any structural standardized data included in the structural standardized data list according to a predetermined vehicle type or the like. The operation unit 106 outputs an operation signal corresponding to this operation to the selection unit 102. Based on this operation signal, the selection unit 102 selects any one of the structure standardized data included in the structure standardized data list (S103). When design requirements such as the strength of parts are defined, the selection unit 102 may generate a screen by excluding structural standardized data that does not satisfy the design requirements from the structural standardized data list. In this case, since the screen does not include structural standardized data that does not satisfy the design requirements, the screen is not selected by the operator. As a result, the selection unit 102 can select only the structure standardized data that satisfies the design requirements.

  Furthermore, the selection unit 102 specifies the template of the selected structural standardized data based on the structural standardized data list. Then, the selection unit 102 searches the structure standardized data DB 108 using the identified template as a key, reads out the structure standardized data associated with the template, and outputs it to the structure standardized data correction unit 112. The structure standardization data correction unit 112 generates a model image representing the shape of the design site using the input structure standardization data as shape data, and displays the model image on the display unit 104 (S104).

In a state where the model image is displayed on the display unit 104, the operator uses the operation unit 106 to input parameters as design item data necessary for correcting the shape of the design part. The operation unit 106 outputs an operation signal corresponding to this operation to the parameter setting unit 110. The parameter setting unit 110 sets parameter information corresponding to the operation signal (S105), and outputs the parameter information to the structure standardized data correction unit 112.

  FIG. 5 shows a cross-sectional view of the design site. In FIG. 5, when the shape of the design part 310 needs to be corrected, the coordinate data of points A, B, and C with the predetermined position as the origin is set as parameter information.

  The structure standardization data correction unit 112 corrects the structure standardization data based on the parameter information from the parameter setting unit 110 (S106). A general function of CAD can be used for the correction. Furthermore, the structure standardization data correction unit 112 refers to the design check item DB 114 to determine whether or not the part satisfies a design condition to be satisfied (S107).

  Then, the structure standardization data correction unit 112 generates a model image representing the shape of the design part using the corrected structure standardization data as shape data, and displays the model image on the display unit 104 (S108).

  If the structure standardized data cannot be corrected due to an inappropriate parameter, the structure standardized data correcting unit 112 generates an alarm sound from a speaker (not shown) to notify the operator to that effect. Processing such as output may be performed. Further, a location that does not satisfy the design condition may be displayed together with the model image on the display unit 104.

  The operator looks at the model image based on the structure standardized data after correction, and determines whether or not the desired shape of the design site has been obtained. If the desired design part shape cannot be obtained, the operator further performs an operation of inputting parameters using the operation unit 106. In this case, the operations after S105 are repeated. On the other hand, when the shape of the design part desired by the operator is obtained, the operations after selection of other design parts (S102) constituting the part to be designed are repeated.

  In this way, the design support system 10 generates shape data representing the shape of the design part for each design part obtained by dividing the design target part into design units, and the structure standardized data representing the structure of the design part is Correction is made based on parameters necessary for correction of the shape of the design site, and the structure standardized data after correction is used as shape data. Therefore, the structure standardized data prepared for each design part is used, and the shape of the part is represented by the combination of the structure standardized data, so that it is possible to deal with the design of parts having various shapes. In addition, since the structure standardized data can be corrected, flexible part design can be easily performed.

In addition, in order to urge the designer to check whether the design requirement required for the design is satisfied for the part designed in this way, a function for displaying the design requirement after completion of the part is further provided. It may be provided.
In the flowchart of the operation of the design support system 10 (FIG. 4), the design check item DB 114 is referred to by the structure standardization data correction unit 112 after the structure standardization data correction (S106) based on the parameters and automatically designed. A rule check was performed. However, the implementation of the present invention is not limited to such a configuration and operation. For example, the check based on the design rule may be performed on the structure standardized data in the structure standardized data DB 108 shown in FIG.
Further, as illustrated in FIG. 1, the design support system 10 includes a confirmation unit 116. The confirmation unit 116 has an icon on the screen operated by the operation unit 106 (pointing device or the like) when the designer requests confirmation. When the designer selects a desired confirmation target from the design objects displayed on the display unit 104 and presses the icon of the confirmation unit 116, the check based on the design rule is executed on the confirmation target. In this case, the designer displays the display unit 104.
The confirmation target may be selected from the model of the design shape displayed on the screen, or the designer may select the confirmation target from a list that displays a list of design shape names.
Further, when the icon of the confirmation unit 116 is pressed after correction by the structural standardization data correction unit 112 or after parameter information is set to the parameter setting unit 110, correction is performed based on the data being corrected or the set parameter information. The data to be checked may be checked by a design rule.

  Structural standardization data representing the structure of the design part is prepared for each design part that divides the design target part into design units, and this structural standardization data is modified and used as shape data, so it can be applied to parts design of various shapes Is possible.
