Description

  The present invention relates to design support technology.

  Automotive parts have high quality requirements and must satisfy a number of quality and design requirements. For this reason, the designer needs to confirm whether or not the automobile parts to be designed satisfy many requirements when developing a new product, and the number of designer man-hours is increasing.

  These quality requirements, design requirements, and the like are generally managed by a management server. Therefore, a mechanism has been provided that allows the management server to reliably manage whether the design object satisfies the quality requirement and the design requirement.

  However, conventionally, there has been no consideration of linking the CAD that sets and stores the dimensions of each part of the design object and the management server that manages the quality requirements and design requirements of the design object. Therefore, among these requirements, for example, regarding the dimensions of each part of the design object, the designer manually measures the numerical values designed by CAD and manually inputs them into the management server to determine the quality requirements and design requirements. I was checking whether I was satisfied. For this reason, measurement mistakes and input mistakes may occur. For example, after measuring the dimension of a specific part on CAD, an error has occurred in which the dimension of the wrong part, which is different from the specific part, is input to the management server.

The following patent documents are known as techniques for supporting such a design.

  ADVANTAGE OF THE INVENTION According to this invention, the dimension information preparation apparatus which sets and memorize | stores the dimension of each site | part of a design target object, and the management server which manages the quality requirements and design requirements of a design target object can be made to cooperate.

  A design support system according to the best mode for carrying out the present invention (hereinafter referred to as an embodiment) will be described below with reference to the drawings. The configuration of the following embodiment is an exemplification, and the present invention is not limited to the configuration of the embodiment.

FIG. 1 is a configuration diagram of the present design support system. The design support system includes a CAD (Computer Aided Design) device 1 (corresponding to the shape information creation device of the present invention) that edits and stores shape data of a design object, and an online check device 2 that cooperates with the CAD device 1 ( And a management server 3 that receives, stores and manages information from the online check device 2 and delivers check items such as dimensional rules to the online check device 2.

  The CAD device 1 has a CPU, a memory, a hard disk, a communication interface, a display device, and an input device (pointing device, keyboard, etc.) not shown, and generates shape information and dimension information of a design object according to a user operation. And remember.

  The shape information is graphic information for specifying the shape of the design object, and is described as, for example, a polygon or a set of surfaces in a three-dimensional space. The dimension information is information indicating the dimension of a specific part of the design object, and includes, for example, identification information indicating the part and a dimension value of the part.

  The CAD device 1 has a user interface (not shown) (for example, an icon on the screen) that receives a dimension check instruction. The user of the CAD apparatus 1 can confirm whether or not the dimensions of each part of the design object satisfy a predetermined dimension rule by operating the instruction interface at a desired time. That is, when the instruction interface is operated, the CAD device 1 transfers the identification information relating to the part of the design object and the dimension value of the part to the online check device 2, and the part has the dimension rule in the online check device 2. Ask to check if you are satisfied.

  The online check device 2 includes a CPU, memory, hard disk, communication interface, display device, and input device (pointing device, keyboard, etc.) not shown. The online check device 2 executes a dimension check of the design object by executing an information processing program on the CPU.

  That is, the online check device 2 receives from the management server 3 a dimension check list including identification information given to each part of the design object and a dimension rule of the part and stores it on the hard disk. On the other hand, upon receiving from the CAD apparatus 1 a request for a dimensional check indicating whether or not the identification information relating to the part of the design object, the dimensional value of the part, and whether or not the part satisfies the dimensional rule, The dimension value of the part is compared with the dimension rule to be satisfied by the part, and it is determined whether or not the part has the dimension rule.

  In the example of FIG. 1, the dimension data transmitted from the CAD device 1 and stored in the hard disk is defined as “gap 1:10 mm”, for example. Here, “gap 1” corresponds to the part identification information. “10 m” corresponds to the dimension value. Further, the dimension checklist is described as “gap 1: 20 mm or more”. Here, the dimension rule is defined such that the part specified by the identification information “gap 1” is “20 mm or more”.

  The online check device 2 receives the image data of the part together with the identification information given to each part of the design object from the CAD device 1 and stores it on the hard disk. If the online check device 2 determines that the dimensional rule of a specific part is not satisfied, the image data of the part is read from the hard disk and displayed on the display device 2A.

  In the present embodiment, such online check processing is executed by the online check device 2, but may be executed by the CAD device 1. That is, instead of providing the online check device 2 separately, online check processing may be realized as an application program on the CAD device 1.

The management server 3 includes a CPU (not shown), a memory, a hard disk, a communication interface, a display device, and an input device (pointing device, keyboard, etc.). Management server 3
Includes at least one of storage of dimension data for all parts, dimension checklist including dimension rules, legal conditions, material / characteristic conditions, and appearance conditions at the time of shipment by executing an information processing program on the CPU. Maintains a comprehensive checklist and manages the check status of parts data based on the comprehensive checklist.

  Here, for example, the dimension check list has dimension rules for all parts of all design objects. The management server 3 receives the transmission request of the dimension rule from the online check device 2, and transfers the dimension rule identified by the identification information for each part of the specific design object as a dimension check list of the design object.

  Further, the management server 3 receives dimension data including identification information for identifying a part and a dimension value of the part of the design object from the online check device 2. The management server 3 also performs a dimension check on the dimension data according to the dimension rule in the comprehensive check list.

  In addition, the management server 3 accepts the user's input as to whether or not the legal conditions, material / characteristic conditions, and appearance conditions at the time of shipment are satisfied, and records them in the general check list. Here, the legal condition refers to a requirement obliged by the legal regulations regarding the design object. The material / characteristic conditions refer to requirements other than the dimensions to be satisfied by the design object, for example, rigidity, elasticity, paint material, and the like. The appearance condition at the time of shipment refers to a condition that should be satisfied upon shipment, for example, whether or not a predetermined label is affixed.

  Then, the management server 3 creates a report based on the dimension check result and the comprehensive check result and displays the report on the display unit 3A. In this embodiment, the dimension check result is a result of the management server 3 checking each part of the design object according to the dimension rule. However, the management server 3 may create a report based on the size check result and the comprehensive check result received from the online check device 2.

  FIG. 2 shows the screen configuration and data flow of this design support system. In the CAD device 1, CAD shape data is displayed on the display device 1A. The user edits and operates the shape data via the input device. The CAD device 1 has a function of measuring the dimensions of each part of the created design object or the design object being created. The measured dimension value of each part is combined with identification information indicating each part to form dimension data.

  When the user selects a predetermined user interface (for example, a dimension check icon (not shown)), dimension data is transmitted from the CAD apparatus 1 to the online check apparatus 2 (arrow 101).

  When the online check device 2 receives the dimension data of the design object from the CAD device 1, the online check device 2 determines whether or not the dimension check list including the dimension rules for each part of the design object has been stored in a hard disk (not shown). . When there is no dimension check list for the design object, the online check device 2 requests the management server 3 for a dimension check list for the design object.

Then, the online check device 2 checks the dimensions of each part of the design object according to the dimension rules of the dimension check list. The dimension check result is transferred to the management server 3 together with the dimension data of each part (arrow 102). The management server 3 checks again whether or not each part of the transferred design object satisfies the dimensional rule in accordance with the dimensional rule in the general check list of the management server 3 itself. In addition, the management server 3 accepts the user's input as to whether or not the legal conditions, material / characteristic conditions, and appearance conditions at the time of shipment are satisfied, and records them in the general check list. Moreover, the management server 3 outputs the evaluation result of the design object as a report (corresponding to a report form of the present invention) to the display device 3A based on the result of the dimension check and the comprehensive check list.

  FIG. 3 is a flowchart showing processing of the CAD apparatus 1. The CAD device 1 detects a user operation via an input device (not shown), and creates the shape of the design object according to the user operation (S1).

  When the user operates a predetermined user interface, the CAD device 1 requests the online check device 2 to perform a dimension check on the design object (S2). At this time, the CAD apparatus 1 transmits the dimension value of each part together with the identification information of each part of the design object to the online check apparatus 2.

  Then, the CAD device 1 waits for a return of the check result from the online check device 2. If the check result is not OK, the fact is displayed on the display device 1A, the control is returned to S1, and the user is prompted to create the shape of the design object again.

  On the other hand, if the check result is OK, the CAD device 1 determines whether there are remaining parts (S4). If there are remaining parts, the CAD device 1 returns the control to S1 and prompts the user to design the next design object. If there is no remaining part, the CAD device 1 transfers the designed dimension data of the design object to the management server 3 and requests accumulation (S5).

  FIG. 4 is a flowchart showing the processing of the online check device 2. In this process, the online check device 2 first determines whether or not an online check request from the CAD device 1 has been received (S11). The online check request includes dimension data for each part of the design target (also referred to as a part) to be checked.

  Next, when the online check request is received, the online check device 2 determines whether or not there is a dimension check list of the design object to be checked online (S12).

  When there is no dimension check list, the online check device 2 requests the management server 3 to request transmission of the dimension check list of the design object. Then, the online check device 2 receives the dimension check list from the management server 3 (S13).

  Next, the online check device 2 performs a dimension check on the design object (S14). Then, the online check device 2 returns the check result to the CAD device 1 (S15).

  Next, when the end of the process is instructed, the online check device 2 ends the process. On the other hand, when the continuation is instructed, the online check device 2 returns the control to S11.

  FIG. 5 is a flowchart showing the comprehensive check process of the management server 3. In this process, the management server 3 refers to the check items in the comprehensive check list (S21). The general check item includes, for example, at least one of a dimensional rule, a legal condition, a material / characteristic condition, and a appearance condition at the time of shipment.

Next, the management server 3 refers to the evaluation information corresponding to the check item (S22). The evaluation information is described as a combination of attributes and attribute values. For example, the dimension rule includes the identification information of the part of the design object and the dimension range. On the other hand, the evaluation information for the dimension rule includes the identification information of the part, the dimension value, and the result of suitability determination.

  Further, the evaluation information of the legal condition is described by a combination of identification information indicating the legal condition and information indicating suitability. Furthermore, the evaluation information for the material / characteristic condition is described by identification information indicating the material / characteristic condition and its attribute value. Further, the evaluation information on the appearance conditions at the time of shipment is described by identification information indicating the appearance conditions at the time of shipment and information indicating suitability. Such evaluation information is generated according to user input.

  Next, the management server 3 outputs the reference result of the evaluation information to the display device 3A according to a predetermined report form (S23). Next, it is determined whether the comprehensive check is finished (S24). That is, if there are still remaining check items, the management server 3 returns the control to S21.

  On the other hand, if all the check items are referred to, it is determined whether or not the target value has been achieved by the evaluation based on the evaluation information (S25). For example, when a predetermined number or more of defects are detected, the target value is not achieved. If not, the user begins redesign work. When the target is achieved, the comprehensive check process ends.

  As described above, when the user operates a predetermined user interface, the CAD apparatus 1 generates dimension data from information indicating each part of the created design object and the dimension value of the part. Along with the command for requesting the check, it is transmitted to the online check device 2.

  When the online check device 2 receives the request for the size check, the online check device 2 determines whether or not the size of each part of the design object matches a predetermined size rule, and returns the result to the CAD device 1. Thus, according to the design support system of the present embodiment, the user can determine whether or not the dimension satisfies a predetermined dimension rule online when the shape of the design object is edited by the CAD device 1.

  If the online check is OK, the dimension value of each part of the design object and the result of the dimension check are transmitted to the management server 3 and accumulated. The management server 3 manages a comprehensive checklist of design objects. The comprehensive checklist includes at least one of dimensional rules, legal conditions, material / characteristic conditions, and appearance conditions at the time of shipment of each part of the design object. Therefore, after the CAD apparatus 1 individually checks the dimensions of the design shape, the management server 3 checks the dimensions according to the dimension rules managed as a comprehensive check list. Therefore, in addition to the individual dimension check process on the CAD device 1, the management server 3 executes the dimension check again according to the dimension rule that is centrally managed as a comprehensive check item, thereby preventing a check omission.

  Further, the management server 3 receives and accumulates information on the suitability of the material / characteristic condition and the appearance condition at the time of shipment in addition to the result of the dimension check for each design object. Therefore, the management server 3 can generate a report (report form) related to whether or not the design object is appropriate regarding the result of the dimension check, the material / characteristic condition, and the appearance condition at the time of shipment.
