Abstract: Determine the conflict in the system was the basis of product innovation, the conflict determination direct at Computer Aided Innovation (CAI) based on design centric complexity was studied. The theory for definitions of complexity and complexity types were firstly introduced. Secondly, according to the definitions the unified representation of Design Centric Complexity was proposed, and this representation was used to judge Design Centric Complexity types. Further the unified method of Design Centric Complexity was refined, and was corresponding to the concepts of problems, conflicts and conflict to form a conflict determination principle based on Design Centric Complexity. Finally, the proposed method was applied in engineering examples to verify the principles.

Key words: design centric complexity, representation of complexity, conflict determination, product design

摘要： 确定系统中的冲突是产品创新的基础，研究了面向计算机辅助创新设计过程复杂性理论冲突确定原理，介绍了设计过程复杂性理论中对复杂性的定义以及复杂性的类型；根据相应的定义提出了设计过程复杂性统一表示方法，并应用该方法进行设计过程复杂性类型判定；将设计过程复杂性的统一表示方法进一步细化，并与问题、矛盾和冲突等概念相对应，形成设计过程复杂性冲突确定原理；应用工程实例验证了设计过程复杂性的冲突确定原理。
