摘　　要：介绍了用发明问题解决理论(TRIZ)中冲突的概念可得到产品创新的高层次解,在此基础上,进一步阐述了设计问题的五种结构,并对典型的点状问题(物理冲突)从时间、空间域将其划分为三种形式,建立了物理冲突的表达模型。对与之相对应的启发式原理进行了拓展。据此理论,建立了产品概念设计过程模型,并编程实现这一过程。用工程实例说明了应用。High-level solutions of product innovation are gained using the contradiction concept of theory of inventive problems solving (TRIZ). From the basic ideas of TRIZ, five constructions of design problems are ulteriorly expounded. Point problems (physical contradictions) are mainly studied, and are classified three forms from time and space region. Representation model of physical contradictions is developed. The numbers of heuristics principles application of solving physical contradictions are added. Based on this principle, a conceptual design model of product is developed, and the design process is realized with software programming. Using an engineering case shows the application of the process.
