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.

摘要： 为激发设计者的创新思维,从认知的角度出发，探索“分析—综合—评估”进程模型、“宽度—深度优先—机会主义”设计策略和“发散—收敛”思维模式之间的内部关系：设计者的思维模式推动设计实践遵循设计进程，以设计策略为实施原则持续进行，由此建立了一个设计思维模型。利用认知实验和linkography数据分析方法验证了模型的有效性。基于该设计思维模型，遵循设计进程的思维特性和设计策略选择偏好原则，组织和推送支持计算机辅助创新设计的系统资源，建立符合设计思维规律、以启发设计者内在思维机制为目的的计算机辅助创新设计流程，为构建高效的计算机辅助创新系统提供理论基础。
