Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a development support system such as a CAD system used for designing components of various mechanical devices such as those for automobiles.

(Prior Art) Currently, computer-based design support systems (CAD systems) are being developed in various fields.

Currently, this CAD system is ahead of the curve in the field of electronic components such as ICs, which have relatively simple wiring patterns that are repeated, but is lagging behind in the field of targeting mechanical parts with complex shapes. It seems that

A CAD system that designs mechanical parts registers a large amount of shape data for each part that makes up the product to be designed in a database, and then selectively retrieves the necessary shape data from the database to create it. It is designed to be incorporated into the drawing inside.

As disclosed in Japanese Patent Application No. 63-138466, a method for managing the shape data registered in the database is to organize the configuration of each part forming a product to be designed into a tree consisting of a parent part and child parts. There are things that are managed in the form of structures.

(Problems to be Solved by the Invention) In the conventional CAD system for the above-mentioned mechanical parts, shape data stored in a database is managed in a tree structure format. For this reason, it is necessary to create a tree structure for each product to be designed, which poses a problem of requiring labor and time.

Furthermore, each time a component is changed due to a design change, it is necessary to change the tree structure, which is a problem in that it is labor-intensive and time-consuming.

Furthermore, in conventional CAD systems, since the data stored in the database is mainly shape data, they tend to remain as mere drawing support systems. For this reason, it is necessary to transfer knowledge about past achievements, know-how, etc. from design experts to design personnel orally or in writing.

In addition, in conventional CAD systems, the data stored in the database is mainly shape data, so when designing a new item that has not been used, it is necessary to search for documents that record past experimental data and conduct experiments. There is a problem that it takes time to design.

Furthermore, in conventional CAD systems, parts are classified using a unique method that takes only the efficient operation of the system into consideration. For this reason, there is also the problem that it becomes difficult for designers who are used to classification methods based on conventional in-house standard parts before the introduction of the CAD system.

Furthermore, in addition to the shape data of the part, drafting also requires the writing of additional symbols specifying surface roughness, dimensional accuracy, etc. However, conventionally, such additional codes have not been registered in a database, so there is a problem that designing them requires a lot of effort and time.

In addition, conventional CAD systems only deal with design drawings, and specifications that describe how to confirm characteristics and the like are prepared in separate documents. For this reason, the amount of effort and time required to create specifications in a series of design tasks is increasing.

(Means for Solving the Problems) According to the development support system of the present invention, various parts constituting a part to be designed are classified into a plurality of part standards while being grouped based on the connection method of each element, For each part standard, a shape data file is created as part of the data file.

Further, for at least a part of the part standard, a design guide file in which design considerations are described and a supporting data file including experimental data are created as part of the data file.

Further, various parts constituting the part to be designed are classified using criteria different from the part standard, and files of shape data of these parts are created as part of the data file.

Drafting standard data including open frames and drafting symbols are also created as part of the data file.

Hereinafter, the operation of the present invention will be explained in detail together with examples.

(Embodiment) FIG. 1 is a system configuration diagram showing the configuration of a development support system according to an embodiment of the present invention.

This development support system includes a processor 10, a database 20, and an end device group 30.

The processor 10 includes a terminal interface module 11
and a file search module 12.

As shown in FIG. 1, the contents of the database 20 are comprised of a part standard database (D/B) 21, a standard parts database 22, and a drafting standard database 23.

The part standard, as illustrated in FIG. 2, is a classification of various parts constituting the part to be designed, grouping them based on their connection methods. For example, if the object to be designed is an automobile part, applicable parts include common parts, mechanical fuel parts, mechanical functional parts, electronic actuators, sensors, and the like.

On the other hand, methods of joining the various parts that make up these parts include fixed, releasable, airtight, bearing, transmission, and single-function fitting. These include soldering, electrodeposition, botting, shrink fitting, and adhesion.

Major classification symbol (
Z, V, etc.) are assigned, and the part standards constituting each part are divided into groups, and each group is assigned a subclassification symbol (Z, A, etc.). Further, item numbers in a serial number format are assigned to all part standards constituting each part. This combination of major classification symbol, minor classification symbol, and item number is used as part of the file identification code of the part standard database 21.

Referring to FIG. 1, for each part standard mentioned above, a design guide 211, supporting data 212, shape data list 213
and shape data group 214 are created and managed.

The design guide 211, which is created and managed for each part standard, is composed of columns for writing reasons for settings and points to be noted, etc., columns for describing explanatory drawings, columns for recording recommended specifications, etc., as illustrated in FIG. 3. There is. In the fields for setting reasons and points to note,
The reason for setting the shape and dimensions of each part in the explanatory diagram with corresponding symbols as shown in the explanatory diagram, and matters to be kept in mind during design are described. Instead of the reasons for such settings and points to note, design guidelines may be written with a title such as establishment mechanism or main design item. The main design guidelines are described based on past experimental data.

In the "Category" column provided for each item in the design guideline above, design memos that are considered important are written with symbols. Applicable conditions regarding the type, material, usage environment, etc. of this part standard are described in the margin of the design guideline in Section 1.

In the column for recommended specifications, recommended values regarding various dimensions described in the explanatory diagram are described as "basic dimensions", "tolerances", etc.

In this way, the design guide created for each part standard fully incorporates the knowledge of experienced design experts. Therefore, by referring to this design guide, relatively inexperienced designers can perform high-level designs comparable to those of experts.

As illustrated in FIG. 4, the supporting data 212 created and managed for each part standard includes various data that support the contents of the corresponding design guide. This supporting data is mainly based on what was collected during the past design process.

This supporting data is particularly useful in determining the degree of risk associated with designing a design that deviates from the range of recommended specifications described in the corresponding design guide.

Shape data list 2 created and managed for each part standard
13, as illustrated in FIG. 5, is composed of a correspondence table between parameters related to various dimensions, such as diameter, and identification codes of shape data files that hold shape data having these dimensions. As the above-mentioned parameters, the orientation and drawing method of drawing, such as a front view, side view, and cross-sectional view, may be used for the same part standard.

In addition to the part standard database 21 described above, various parts constituting the part to be designed are classified using criteria different from the part standards described above, and files of these shape data are created and managed as a standard parts database 22. Ru.

This standard part is an in-house standard part classified based on a conventional classification method. As shown in FIG. 1, this standard parts database 22 is composed of a shape data list 221 and a plurality of shape data selected by referring to this shape data list.

The shape data list 221, as illustrated in FIG.
It consists of a combination of types of parts and their respective drawing modes. A plurality of shape data 222 corresponding to these combinations are held in a shape data file having a file identification code written in the shape data list.

Referring again to FIG. 1, data file 20 also includes a drafting standards database 23.

As shown in FIG. 1, this drafting standard database 23 is composed of a data list 231, diagram frame data 232, drafting symbol data 233, and specification format data 234.

The drawing frame data 232 is classified according to the size of AO-A4 drawing paper and the format of the title block, and a file identification code is attached to each.

In addition, drafting symbol data consists of symbols that indicate surface finish accuracy, dimensional accuracy such as coaxiality and parallelism, welding symbols, and symbols of electrical and electronic elements, and a file identification code is attached to each symbol. There is. Furthermore, the specification data consists of a specification cover page, the next page of the specification, and a figure frame in a predetermined format that describes the specifications for confirming the functions of the designed parts, each of which is assigned a file identification code. There is. The data list 23 shows the correspondence between the file names of the above-mentioned drawing frame data, drafting symbol data, and specification format data and the file identification codes assigned to each.
1 in the form of a list.

When a user, who is a designer, inputs a necessary file identification code from one of the terminal devices 30, the file search module 12 in the processor 10 is activated, and the data file with the file number held in the database 20 is retrieved. is searched and the terminal interface module 11
is transferred to one of the corresponding terminal devices 30, displayed on that display device, and referred to by the designer.

By referring to the design guide, supporting data, etc. displayed on the screen of the terminal device, the designer can perform a design as sophisticated as that of a design expert. In addition, the designer also checks the drawing frame data, shape data, and
You can copy drafting symbol data, etc. onto the screen that is currently being displayed, or draw figures on the screen via the drawing module in the terminal device (thereby creating a design drawing. The drawing is saved in a save file within the terminal device.

Various data in the database 20 are registered or updated based on data created by a design expert, and are managed by adding a file identification code.

In the above, a configuration has been exemplified in which the drawing function and the function of storing design drawings that are being created or have been created are distributed and provided to each of the terminal device groups. However, these functions cannot be implemented by the processor 10.
It is also possible to have a configuration in which the functions are concentrated on.

(Effects of the Invention) As explained in detail above, the development support system of the present invention classifies various parts constituting a part to be designed into a plurality of part standards by grouping them based on the connection method of each element. death,
