Abstract: 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.

Key words: generation of creative idea, theory of inventive problem solving, computer-aided innovation, product conceptual design, process model
