Some Key Problems for Computer Aided Conceptual Design of Mechanical Products

This paper discussed the definition and connotation of the conceptual design of mechanical products. It analyzed the relation between the needs of market and the functions of products. It studied the method of concept design of mechanical products based on the technological action process, and the method of establishment of domain knowledge based on the basic characteristic of action. It inquired into the practical method of creative concept design of mechanical products. It also studied the method and key technology of computer aided conceptual design for mechanical products, and put forward the conclusion that the conceptual design for mechanical products should establish the function design model and mechanical movement scheme based on the basic characteristics of mechanism system.
