Description

  The present invention relates to a design support system and a design support method, and more particularly, to a support technology used when a plurality of persons in charge design a unit mounted on a vehicle.

  In conventional engine development, first, an engineer determines basic specifications of an engine, such as output performance, exhaust performance, fuel consumption performance, and the like. Then, each person in charge of the parts constituting the engine examined the development contents of the parts, and the engine person in charge compiled detailed specifications of the engine determined as a result.

  In the above engine development procedure, each part person in charge examines each part based on information from the engine person in charge. Relied on knowledge of. In this way, the presence or absence of other affected parts and the method of obtaining information about the parts were different depending on the person in charge, so there were cases in which the examination conditions were omitted, the leakage, the examination content was missing, or the leakage occurred. .

  In addition, there was no rule for information exchange between the engineer and the parts manager, and the contents were not centrally managed, so that the work was reworked due to omissions, omissions, misinterpretation of information, and the like.

  The first feature of the present invention is that the specification of the vehicle, the specification of the unit mounted on the vehicle, and the integrated specification table for storing the specifications of the parts constituting the unit in a database, and the design required for the parts are necessary. A business navigation unit that extracts information from the integrated specification table and presents it to a designer of the component together with a design procedure for the component, and a CAD template that three-dimensionally displays the component designed using the business navigation unit A design support system having the first or second symbol of the part change content entered by the designer of the part in the integrated specification table is registered in the part change content of the part specification database in the integrated specification table. The related change review table selects parts and items related to the item in which the first symbol in the part change contents of the integrated specification table is entered, and The first symbol is displayed in the “relevant review required” column and “relevant review status” column for the corresponding item in the screen, and at the same time the display color of the item related to the item with the first symbol is changed The gist is to do.

  The second feature of the present invention is that the specification of the vehicle, the specification of the unit mounted on the vehicle, and the integrated specification table for storing the specifications of the parts constituting the unit in a database, a business navigation unit, a CAD template A design support method using a design support system comprising: a step of registering a basic specification of the unit input by a designer of the unit in the integrated specification table; and the business navigation unit includes the component Information necessary for designing is extracted from the integrated specification table and presented to the designer of the part together with the design procedure of the part, and the CAD template is a three-dimensional view of the part designed using the business navigation unit. The first symbol or the second symbol of the content of the component change input to the integrated specification table by the component designer The stage of registration in the part change contents of the part specification database in the integrated specification table, and the related change examination table are the parts and items related to the item in which the first symbol is entered in the part change contents of the integrated specification table. The first symbol is displayed in the “relevant review required” column and “relevant review status” column for the corresponding item in the part specification, and at the same time, the item related to the item in which the first symbol is entered is displayed. And a step of changing the display color.

  According to the present invention, when changing the specification of a part, by displaying other parts that need to be considered for a change in the specification, it is possible to prevent omission of the examination of the part and eliminate inconsistencies between the parts. A design support system and a design support method with improved quality can be provided.

  Embodiments of the present invention will be described below with reference to the drawings. In the description of the drawings, the same or similar parts are denoted by the same or similar reference numerals.

  As shown in FIG. 1, the design support system according to the embodiment of the present invention includes an integrated specification table that stores an engine specification, a specification of a vehicle on which the engine is mounted, and a specification of parts constituting the engine in a database. 1. Information necessary for the design of parts is extracted from the integrated specification table 1 and presented to the part designer together with the part design procedure, and the parts designed using the business navigation part 6 are three-dimensional. And a related change examination table 31 that defines the presence or absence of the influence of individual component specifications.

  In the embodiment of the present invention, the case where the present invention is applied to engine design will be described, but the present invention can also be applied to a unit other than the engine mounted on a vehicle.

  The integrated specification table 1 has the functions of a vehicle specification database 2 that holds data related to vehicle specifications, an engine specification database 3 that holds data related to engine specifications, and a component specification database 4 that holds data related to component specifications. Yes. The part specification database 4 includes part change contents 32 and part spec 33 data. The integrated specification table 1 collectively manages the data stored in the databases 2 to 4. The integrated specification table 1 further holds data indicating a mutual relationship defined between two or more pieces of data held by the integrated specification table 1. For example, when there are parts that fit together, the interrelationship between the fitting parts is also recorded and held in the integrated specification table 1.

  The engineer or parts manager uses the integrated specification table 1 to register the development contents for each part in the parts change contents 32. Here, “◯” as the first symbol or “×” as the second symbol is input. The integrated specification table 1 extracts specs that need to be examined for the change contents of individual parts in the part specifications 33 from the contents of the part change contents 32 and the related change examination table 31.

  In the extracted part specifications, “◯” is displayed in the “review required” column and “◯” is displayed in the “review status” column, and the display color is changed.

  For the extracted component specifications, the “review status” column is changed from “◯” to “done”, data is registered in the integrated specification table 1 and the display color is restored. The project manager can confirm whether or not the design considering the influence of other parts is made by confirming the “examination status” column.

  When the display of “◯” is selected from the change items of the part change content 5 in the integrated specification table 1, the related change examination table 31 is displayed, and other parts related to the selected change content are displayed.

  When “O” display in the “review required” column of the part specification 33 is selected in the integrated specification table 1, a related change review table 31 is displayed, and the contents of changes of other parts related to the selected part specification are displayed. The person in charge of parts can examine the specifications while confirming other parts that affect the part without omission.

  In this way, first, the change contents of the parts are input to the part change contents 32 of the integrated specification table 1. Thereafter, the relevant examination items are extracted from the relevant change examination table 31 and displayed on the component specification 33 in the integrated specification table 1. Thereby, it is possible to automatically determine the relationship between the component specifications, eliminate omission of examination and leakage, and prevent rework. In addition, by digitizing the design procedure, it is possible to eliminate variations in the quality of spec review by the person in charge and to eliminate rework due to missing contents, leakage, misinterpretation of information, and the like.

  A designer of a part constituting the engine uses the business navigation unit 6 to design the part according to a part design procedure provided by the business navigation part 6 and information necessary for the part design. Here, the “information necessary for the part design” provided by the business navigation unit 6 includes information extracted from the vehicle specification database 2, the engine specification database 3, and the part specification database 4. Note that information necessary for the design of the part is extracted from the part specification database 4 when the examination result of other parts constituting the engine is registered.

  The business navigation unit 6 supports the design of parts by the designer, and also has a function of a part design database 7 that holds specifications of the parts designed by the designer. The business navigation unit 6 stores the specification of the part designed by the designer in the part design database 7 and also registers it in the part specification database 4 of the integrated specification table 1. That is, all the contents examined by the parts person in charge (designer) using the business navigation unit 6 are registered in the parts design database 7, and the engine specifications determined from the examination results are the engine specifications database 3. In addition, the specifications of parts required by other parts managers are registered in the parts specification database 4 respectively. Thereby, the examination result of the specification of the said part can be shared with the designer of other parts. Further, the engineer can manage the detailed specifications of the engine determined by the examination result of the parts by checking the engine specification database 3 from the integrated specification table 1.

  As described above, the integrated specification table 1 further holds the mutual relationship defined between two or more pieces of data held by the integrated specification table 1, so that the business navigation unit 6 is a component designed by the component designer. The other specifications having the mutual specifications are presented to the designer. For example, when the designer designs or changes one of the specifications of the parts to be fitted to each other, the business navigation unit 6 presents to the designer so that the other specification having an interrelation with the specification is also considered. . In this way, the part designer can easily recognize that it is necessary to study not only the specifications of the part but also other specifications of the same part or other parts.

  The business navigation unit 6 urges the designer to proceed with the design of the part using the reference document / standard document 5, the market price / experiment database 8, or the CAD template 11. When designing a part using the business navigation unit 6, the designer uses the standard / standard document 5, the market price / experiment database 8, or the CAD template 11 according to the instructions of the business navigation unit 6. Examine specifications and proceed with component design. The CAD template 11 displays a three-dimensional image of a component shape on a predetermined display device, and the designer can proceed with the design of the component with reference to the three-dimensional image of the component displayed on the display device. The CAD template 11 holds the 3D shape data 12 and retrieves it as necessary.

  As shown in FIG. 2, the engine design support system of FIG. 1 is realized via a communication network such as the Internet 17. The integrated specification table 1 in FIG. 1 is constructed in a server (here, the first server 15) connected to the Internet 17 via the router 24a, and the business navigation unit is the same first server as the integrated specification table 1. 15 is built. The second server 16 is also connected to the Internet 17 via the router 24b. The second server (CAD server) 16 holds the CAD template 11 including the 3D shape data 12 of FIG. 1, the standard / standard document 5, and the market price / experiment database 8.

  Normally, an engine is composed of multiple parts, and engine engineers who are responsible for designing the entire engine and engineer parts that are responsible for designing each part of the engine exchange information with each other. We are promoting. These engine staff and parts staff perform design and information exchange using different communication terminals at different locations. For example, a plurality of establishments (here, the first establishment 22 and the second establishment 23) are connected to the Internet 17 via routers 24a and 24d, respectively. In the first office 22, a plurality of communication terminals 19 a to 19 d are connected to each other via the local area network 18. Similarly, in the second office 23, a plurality of communication terminals 21 a to 21 d are connected to each other via the local area network 20. The engineer and the parts manager can design and exchange information at different locations by using the communication terminals 19a to 19d and 21a to 21d, respectively. Specifically, the engineer and the parts manager start the business navigation unit 6 using the communication terminals 19a to 19d and 21a to 21d, and the integrated specification table 1 built in the first server 15 is established. Information necessary for designing the part is taken out from the communication terminals 19a to 19d and 21a to 21d together with the design procedure.

At this time, the component person in charge of the component proceeds with the design of the component by examining using the reference document / standard document 5, the market price / experiment database 8, or the CAD template 11 according to the instruction of the business navigation unit 6.

  (D) In step S05, the component person in charge of the component activates the CAD template 11, displays a three-dimensional image of the component shape on a predetermined display device, and displays the three-dimensional image of the component displayed on the display device. Refer to the design of the part. At this time, the CAD template 11 extracts and displays the 3D shape data 12 as necessary.

  (E) In step S06, the business navigation unit 6 investigates whether there is another specification in which the specification of the part designed by the person in charge of the part has an interrelationship. Present to the person in charge. Steps S04 to S06 are repeatedly performed as necessary, and the design of the component in step S04 proceeds.

  (F) Finally, in step S07, the business navigation unit 6 stores the specification of the part designed by the designer in the part design database 7 and registers it in the part specification database 4 of the integrated specification table 1. According to the above procedure, the person in charge of each part constituting the engine proceeds with the design of the part, whereby the entire engine is developed.
