Based on the temporal correlation and function complement between morphological methods and theory of inventive problem solving (TRIZ) on generating and analyzing the principle solutions in product design process, a doublematrix integrated model which combined morphological matrix and conflict resolving principles was proposed. The model system consists of concept model, process model and relation model which build models from approach idea, design process and relations between methods respectively, and follows a topdown spiral design approach. Based on the background of systematic design approach, the applicable scope of morphological analysis is extended to concept level by the model, and the combination capability of principle solutions can be analyzed, so that the coupling problems can be found in the early front-end of design process; the conflict resolving principles ars used on generating solutions and solving design decoupling in order to ensure the continuity of the design process and the creativity of the results. Taking the innovative development process of a hand driller as an example, the application process of the double-matrix on new product design and the implementation of the nested sub-cycle on variant design were validated, and the flexibility and operability of the model when facing deferent designing problems were proved.
