The three-dimensional CAD model input unit 3 generates, for each product, information indicating a connection relationship between components constituting each product based on the three-dimensional CAD model of a plurality of products registered in the model database 2. More specifically, the three-dimensional CAD model input unit 3 expands connection information of parts constituting the three-dimensional CAD model read from the model database 2 in an inter-part connection table as part connection information.

  Returning to FIG. 1, the connection information organizing unit 4 is based on the inter-part connection tables 12, 13, and 14 of the three-dimensional CAD model of each product, and information indicating the parts constituting each product, and all of a plurality of products. The information which shows the connection relation between these parts is produced | generated.

  The connection information organizing unit 4 will be described in more detail. FIG. 6 schematically shows the operation of the connection information organizing unit 4. As shown in FIG. 6, the connection information organizing unit 4 uses the data in the inter-part connection table 12 for the product α, the data in the inter-part connection table 13 for the product β, and the data in the inter-part connection table 14 for the product γ. input.

  Subsequently, the connection information organizing unit 4 organizes which parts are used in which products based on the inputted data of the inter-part connection tables 12, 13, and 14, and indicates information indicating the parts constituting each product. Is generated. In FIG. 6, the all parts usage table 20 corresponds to this. That is, the data of the all parts usage table 20 corresponds to the second information.

  In addition, the connection information organizing unit 4 generates information indicating the connection relationship between all the components across a plurality of products based on the input data of the inter-component connection tables 12, 13, and 14. More specifically, the connection information organizing unit 4 synthesizes the inter-part connection table 12 of the product α, the inter-part connection table 13 of the product β, and the inter-part connection table 14 of the product γ to obtain an all-part connection table 21. Generate. In this embodiment, the data in the inter-component connection table 21 corresponds to the third information.

  The connection information organizing unit 4 outputs the data of the all component usage table 20 and the data of the all component connection table 21 to the module characteristic determining unit 5.

  Returning to FIG. 1, the module characteristic determination unit 5 relates to the grouping policy, the characteristics related to modularization of parts, and the connection to other parts based on the data of the all parts usage table 20 and the data of the all parts connection table 21. Information including constraint conditions is generated for each part. In other words, this information can be said to be information relating to how the parts are used in a plurality of models, that is, information relating to design guidelines for products using the parts.

  FIG. 7 shows the operation of the module characteristic determination unit 5. As shown in FIG. 7, the module characteristic determination unit 5 inputs an all parts usage table 20 and an all parts connection table 21. The module characteristic determination unit 5 generates a module characteristic table 22 based on the input all parts usage table 20 and all parts connection table 21. In this embodiment, the data of the module characteristic table 22 corresponds to the fourth information.

  As shown in FIG. 7, in the module characteristic table 22, a grouping policy, module characteristics related to modularization of parts, and connection restrictions with other parts are registered for each part.

  The grouping policy is information regarding parts to be grouped. More specifically, the grouping policy indicates a group of parts for which all parts are recommended to be grouped with other parts and designed by a single designer.

  For example, the parts A and B are connected to each other in the inter-part connection table 21 and the parts A and B are commonly used for the products α, β, and γ. The module characteristic determination unit 5 sets the parts A and B to be grouped with A and B, respectively, as a grouping policy. The module characteristic determination unit 5 sets the necessity of grouping for other parts. That is, the module characteristic determination unit 5 determines combinations of components used for all products and connected to each other as a grouping component.

  The module characteristic is information indicating whether each part is a platform part, an optional part, or an individual part that is different for each product. More specifically, whether the module characteristic is a platform component that is commonly used by any product, that is, a platform component, or an optional component that may or may not be used by the product. Or any individual part that uses different parts for each product.

  For example, since the parts A and B are used in all products α, β, and γ, the module characteristic determination unit 5 sets the parts A and B as platform parts. Further, since the part C is used for the products α and γ and is not used for the product β, the module characteristic determining unit 5 sets an optional part.

  In other words, the module characteristic determination unit 5 determines the parts used in all products as the parts to be the platform. Further, the module characteristic determination unit 5 determines parts used in some products as optional parts. Further, the module characteristic determination unit 5 determines a part used for one product as an individual part.

  The connection constraint column with other components indicates components that can be connected to a certain component. In other words, the connection constraint column includes constraint conditions for other components to be connected. For example, only the parts D and E can be connected to the parts A and B, and the parts B and D can be connected to the part C. Note that the parts to be grouped are excluded from the parts set in the connection constraint column.

  Returning to FIG. 1, the module characteristic determination unit 5 outputs the data of the generated module characteristic table 22 to the three-dimensional CAD model output unit 6.

  The three-dimensional CAD model output unit 6 reconstructs a three-dimensional CAD model based on the data of the module characteristic table 22.

  FIG. 8A and FIG. 8B show the operation of the three-dimensional CAD model output unit 6. The three-dimensional CAD model output unit 6 inputs the module characteristic table 22, and the information described in the module characteristic table 22 is input to the three-dimensional CAD model 7 of the product α, the three-dimensional CAD model 13 of the product β, and the product γ. The three-dimensional CAD model 14 is added to the attribute information of each part CAD model.

  Further, the three-dimensional CAD model output unit 6 as the reconstruction unit, for example, changes the configuration of the three-dimensional CAD model 23 of the product before input shown in FIG. 8A according to the grouping policy of the module characteristic table 22, for example. As shown in FIG. 8B, the image is reconstructed like the three-dimensional CAD model 24 after the input. In FIG. 8B, the parts A and B of the product α are combined into one module.

  The three-dimensional CAD model output unit 6 outputs the three-dimensional CAD model of the reconfigured product to the model database 2 and updates the three-dimensional CAD model of each product.

  Next, the overall operation of the product modularization process apparatus 1 will be described.

  FIG. 9 is a flowchart showing the overall operation of the product modularization process apparatus 1. As shown in FIG. 9, the product modularization process apparatus 1 inputs a three-dimensional CAD model from the model database 2 by, for example, an operation input (step S1).

  Subsequently, the product modularization process device 1 generates an inter-component connection table based on the input three-dimensional CAD model (step S2).

  Subsequently, the product modularization process apparatus 1 determines whether there is a non-input three-dimensional CAD model (step S3). More specifically, the product modularization process apparatus 1 displays a display screen for inquiring the user whether there is a three-dimensional CAD model to be further input. The user views this display screen and inputs whether or not there is an uninput three-dimensional CAD model. The product modularization process device 1 determines whether there is a non-input three-dimensional CAD model based on the input result.

  When it is determined that there is an uninput three-dimensional CAD model (step S3; Yes), the process returns to step S1. Thereafter, until it is determined that there is no uninput 3D CAD model (step S3; No), the product modularization process apparatus 1 inputs a new 3D CAD model (step S1) and the inter-part connection table. The generation (step S2) and the determination (step S3) are repeated. By this procedure, the inter-component connection tables 12, 13, and 14 are generated.

  If it is determined that there is no uninput three-dimensional CAD model (step S3; Yes), the product modularization process device 1 uses the all-parts use table 20 based on the generated inter-part connection tables 12, 13, and 14. Is generated (step S4).

  Subsequently, the product modularization process apparatus 1 generates the all-parts connection table 21 based on the generated part-to-part connection tables 12, 13, and 14 (step S5).

  Subsequently, the product modularization process device 1 generates data of the module characteristic table 22 based on the all component usage table generation 20 and the all component connection table 21 (step S6).

  Subsequently, the product modularization process device 1 updates the three-dimensional CAD model included in the model database 2 based on the data of the generated module characteristic table 22 (step S7).

  Subsequently, the product modularization process apparatus 1 reconfigures the configuration of the three-dimensional CAD model in accordance with the grouping policy of the module characteristic table (step S8). After step S8 ends, the product modularization process device 1 ends the process.

  This embodiment is effective for the process of designing a three-dimensional CAD model and determining the parts to be shared and modularized in the initial stage of the design.

  As described above in detail, according to this embodiment, information on the parts included in the three-dimensional CAD model of the product and information on the connection relationship between the parts are displayed (information indicating the parts constituting each product (all Product usage table 20) and information (connection table 21 between all components) indicating connection relations between all parts across a plurality of products, and design of products using the parts based on the information Information about the guidelines can be automatically generated. For this reason, it is possible to automatically obtain design guidelines for products using the parts without inputting various information related to the parts. Therefore, more effective and efficient product modular design is possible. It becomes possible.

  The modularization of the part model constituting the three-dimensional CAD model brings various benefits. For example, even a designer who has little design experience can easily proceed with design using common parts, considering the characteristics of the parts, and keeping connection restrictions.

  For example, a modularized part can be designed without setting individual parts. In addition, considering the component characteristics, it is possible to select a platform part, and based on that, select an optional part or an individual part, so that the design can be narrowed down to make the design procedure more efficient. Is done. In addition, due to connection restrictions with other components, it is possible to prevent an erroneous design that connects components that should not be connected.
