Abstract: To inspire innovations of designers, internal relationships among “Analysis Synthesis Evaluation（ASE）”design process paradigm, “width-depth first opportunistic” design strategy and“divergence convergence” thinking mode were explored from the cognitive perspective. Designers thinking mode promoted design practice to follow the design process with design strategies for the principle of implementation. And a design thinking model was established with this principle. The effectiveness of model was verified via cognitive experiment and data analysis method linkograph. Based on the design thinking models, following the thinking law of design process, the theoretical process of computer aided innovative design aiming at inspiring the designers inner thinking mechanism was established, with structuring and pushing resources which supported computer aided innovative concept design system following the design process of thinking characteristics and the preference of design strategy principles. The research provided a theoretical foundation for constructing efficient computer aided innovative design system.
