Abstract: Based on the characteristics of product design, incorporating cognitive psychology, information technology and design theory, a creative qualitative model of product innovation design was developed. The key attributes of the model, namely creative thinking and computer supporting tools, were analyzed. The trend and approaches to improve designers creativity for product innovation were presented. Based on the cognitive process, the design activities were defined and represented. Creative design was conducted under different strategies, and a systematic creative design approach supporting man-machine interaction was put forward. Finally, a prototype software system of computer-aided design for product innovation was developed.

Key words: creative model, creative thinking, product creative design, computer aided creative design

摘要： 根据产品设计的特点，会聚了认知心理学、信息技术和设计理论，建立了产品创新设计的创造力定性模型；分析了产品创新设计创造力的关键属性、创造性思维模式和计算机支持工具，提出了提高产品创新设计创造力的方向和方法。根据认知过程，对设计问题进行定义和表征，并采用不同的策略进行创新设计，建立了系统化的人机交互创新设计方法。在此基础上，建立了一个初步的原型系统。
