对机械产品概念设计的定义、内涵进行了畅述,分析了市场需求与产品功能之间的关系,研究了基于工艺动作过程的机械产品概念设计和基于动作基本特征的执行机构库的建立方法.对机械产品概念设计创新性的具体实施方法进行了探讨;研究了计算机辅助机械产品概念设计的关键框架,提出了机械产品概念设计应按机械基本特点建立功能求解模型和组成机械方案.

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.
