  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows an embodiment of a search device according to the present invention. The condition setting unit 101 sets conditions for searching for parts. The performance parameter database 102 stores performance parameter data of parts. The search unit 103 searches for performance components that meet the search conditions set by the condition setting unit 101 from the parameter data of the performance components stored in the performance parameter database 102. The display unit 104 displays the result parts searched by the search unit 103.

  FIG. 2 shows an example of an assembly part. The parts 1 and 2 have parameters as shown in the figure, and GapA is defined for the gap. Further, GapB is defined as a reference dimension. In the constraint condition setting unit 101, for example, constraint conditions such as GapA <10 and GapB <10 are set. Further, when the component 2 is changed depending on the change of the component 1, the value of the parameter L of the component 1 is also set as a constraint condition. When the parameter L of the component 1 becomes small, GapB becomes small if the component 2 and the gap GapA remain unchanged. When GapB does not satisfy the constraint condition, GapA may be changed when GapA is changed and the constraint condition is satisfied. However, when the constraint condition is not satisfied, component 2 needs to be changed. In this case, the design man-hours and the production preparation man-hours can be reduced by replacing the parts 2 with parameters having proven results, rather than changing the parameters of the parts 2 and creating new parts.

  FIG. 3 is an example of parameter data of actual parts stored in the actual parameter database 102. In FIG. 3A, a part name 302 and a part type 303 for the record number 301 are stored as an example of the parameter data of the result part. In FIG. 3B, the parameter name 304 and the parameter value 305 of the record number 301 are stored as an example of the parameter data of the result part. In addition, a parameter for determining the arrangement position of the component and a dependency relationship of the reference parameter are stored.

  For example, the search unit 103 has a configuration as shown in FIG. The parameter condition creating unit 401 creates a parameter condition from the condition data set by the condition setting unit 101 and the dependency relationship between the reference parameters stored in the actual result parameter database 102. The parameter search unit 402 searches the actual component parameters stored in the actual parameter database 102 for actual components that meet the parameter conditions created by the parameter condition creating unit 401.

In the case of searching for a replaceable part of the part 2 by changing the L of the part 1 with the device of FIG. 2, the parameter condition creating unit 401 uses GapA ≧ 10, GapB ≧ 10, set by the condition setting unit 101. L = 50
And the condition
GapB = LA-GapA
A parameter condition of A ≦ 30 that is a parameter of the component 2 is created from the dependency relationship stored in the result database. In the case of the parameter data of the result parts stored in the result parameter database 102 shown in FIG. 3, the parameter search unit 402 presents parts satisfying the above conditions as replacement candidate parts.

  FIG. 5 shows the results of the parts 3 and 4 displayed in the part display unit 105 after the parameter search unit 402 searches for the parts 3 and 4 corresponding to the record numbers 1 and 2 as the parts satisfying the above conditions. It is an example of data. Part 3 and part 4 satisfying the conditions and the parameter values of each part are displayed.

  FIG. 6 shows a second embodiment of the search unit 103. The scoring unit 601 has a configuration in which a score is added to the result data searched by the parameter search unit 402 and displayed on the display unit 104. The method of assigning the score is obtained by the following formula, for example, by weighting the parameters so that a value close to the current value becomes a high score.

Σall _parameters {1-ABS (current value-actual value) / (maximum actual value)
-Minimum actual value)} * weight * 100
In addition, the highest possible score may be a high score, and the lowest possible score may be a high score. In that case, the current value of the above formula is replaced with the maximum value of the actual result and the minimum value of the actual result, respectively.

  The parameter weight is set by a setting file as shown in FIG. 7, for example. In this example, the weight 702 for the parameter 701 in the component type B is represented. FIG. 8 is a display example including a score on the display unit. The scores and parameter values of the parts 3 and 4 that satisfy the conditions are displayed.

  FIG. 9 shows an embodiment of the CAD apparatus of the present invention. The actual CAD database 902 stores CAD data of actual parts. The replacement unit 901 selects a result part to be replaced from the result parts searched by the search unit 103, and replaces the selected result part with a replacement source part on CAD data. For example, when the part 3 is selected on the display screen as shown in FIG. 10, the part 2 is replaced with the part 3. FIG. 11 shows an example of the CAD screen after replacement. Part 2 is replaced with part 3.

  Next, FIG. 12 shows an embodiment of a search method according to the present invention. The condition setting step 1201 sets conditions for searching for parts. The search step 1202 searches the actual component that matches the search condition set in the condition setting step 1201 from the parameter data of the actual component. A display step 1203 displays the result parts searched in the search step 1202.

  The search step 1202 is configured in detail as shown in FIG. 13, for example. The parameter condition creating step 1301 creates a parameter condition from the condition data set in the condition setting step 1201 and the dependency relationship between the reference parameters. The parameter search step 1302 searches the actual part parameters for actual parts that meet the parameter conditions created in the parameter condition creating step 1301.

  FIG. 14 shows a second embodiment of the search step 1202. In the scoring step 1401, a score is added to the result data searched in the parameter search step 1302 and displayed in the display step 1203.

  FIG. 15 shows an embodiment of a CAD data replacement method according to the present invention. The replacement step 1501 selects a result part to be replaced from the result parts searched in the search step 1202 and replaces the selected result part with a replacement source part on CAD data.
