Research on the Integration of Product Concept Design and Particular Design Driven by CAI Technology

Specific to problem on the innovation concept scheme that put forward by computer-aided innovation (CAI) technology cannot be output successfully to CAD system, starting from analyzing CAD assembly structure model with product functional and structural information, problems and conflicts of assembling model are analyzed and identified through establishing information model figure of product assembly structure. Then the problems are solved by applying integrated innovation technology of knowledge based engineering (KBE) and semantic processing technology driven by CAI technology, so as to promote product structure design and the problems that existing in the assembly structure are solved in an innovative way. Accordingly, the organic innovation process in sequence of innovation schema generation-forming knowledge-driving structure design is formed, and the integration of concept design and particular design is preliminary realized. Further, the integrated process model consists of product conceptual design and detailed design driven by the CAI technology is constructed. Finally, a no-wear butterfly valve product innovation case study shows the feasibility of the model.
