Generation of creative ideas was critical in the product conceptual design process. The obstacle to idea generation in the process was that desigers didn't make full use of knowledge in different fields. Theory of Inventive Problem Solving (TRIZ) based Computer-aided Innovation Systems (CAIs) provided a platform for knowledge application in different fields. Principles of creative idea generation driven by Computer-aided Innovation (CAI) was put forward, the inventive problem was solved based on the design scenario of CAIs, the extended solution space was set up by (Unexpected Discoveries)UXD which was implied in the source design in order to drive the generation of creative idea, then, an integrated process model of creative idea generation for product conceptual design driven by CAI was developed. Idea generation for a safety isolation butterfly valve was carried out using the process model and demonstrated its feasibility.%创新设想产生是产品概念设计阶段的关键环节,影响该阶段设想产生的障碍是设计人员不能很好地利用多学科领域的知识.鉴于此,基于发明问题解决理论的计算机辅助创新软件系统提供了应用多学科领域知识的一个平台.提出了计算机辅助创新驱动的创新设想产生原理,以计算辅助创新软件为设计场景进行问题求解,基于源设计中的未预见的发现建立扩展解空间,驱动创新设想产生,进而建立了计算机辅助创新驱动的产品概念设计创新设想产生过程模型.通过安全隔离蝶阀创新设想产生验证了该模型的可行性.
