Abstract

A product design CAD data reconstruction unit 50 reconstructs product design CAD data used for product evaluation regarding an initial design so as to fulfill restrictive conditions obtained from the product evaluation based on a product structure for the initial design. The reconstructed product design CAD data is stored in a product design CAD data database 90. Upon reception of a corrected design obtained by correcting the initial design, the product design CAD data for the initial design is read from the product design CAAD data database 90, and the product design CAD data is corrected along a design surface of the corrected design.

Dependent claims

A product design system for performing structure designing of a product, comprising:

an initial design reception unit for receiving initial design information of the product;
a product design information generation unit for generating product design information containing design procedure information and a structure of the product based on the initial design information and the design procedure information for defining a design procedure of the product;
product evaluating means for evaluating the product based on the product design information;
a product design information reconstruction unit for reconstructing the product design information to fulfill restrictive conditions for the structure of the product defined by the production evaluation, and adding the restrictive conditions to the design procedure information;
a corrected design reception unit for receiving corrected design information obtained by adding correction to the initial design information;
a product design information reading unit for reading the reconstructed product design information;
and
a product design information correction unit for correcting the reconstructed product design information to fulfill the restrictive conditions based on the corrected design information.
