In order to perform innovative design rapidly and effectively,and to accelerate innovative product design process with advanced technologies,the Computer Aided Innovation（CAI）was integrated with Axiomatic Design（AD）and Theory of Inventive Problem Solving（TRIZ）,and a computer-aided axiomatic design system model integrating TRIZ was proposed.The aspects TRIZ methods integrated in AD framework was extended to simplify design process and obtain innovative design results.A fuzzy design scheme evaluation method based on the information axiom was presented to improve the implementation of AD in design evaluation.The theory of fuzzy mathematics was employed to quantify evaluation indices,promote application of AD in scheme evaluation and provide a scientific basis for decision-making.Finally,aprototype system implementing the proposed model was developed.And the case study of the structure improvement of a parking mechanism demonstrated the validity and practicability of the system.
