摘　　要：将产品设计看作功能实现问题,提出一种基于变功能参数的机械产品创新设计方法。在对机械系统的组成进行分析的基础上,建立了功能特征模型和功能参数知识库,运用变功能参数操作,实现了产品功能的变异和扩展以及结构的重构,从而达到产品创新设计的目的。实例验证了该方法的实用性和有效性。Product design was considered as functional satisfaction problem, and an innovative approach of mechanical product design using function parameter mutation operation was presented. In view of the complexity of mechanical products, the functional characteristic model and the knowledge library of function parameters were established. Through the function parameter mutation operation, then function and structure of products were modified and generated. The design processes can be used to obtain a variety of innovative products. Finally, an example was illustrated the practicality and effectivity of the proposed method.
