Abstract: To make product design meet market requirements and be identical with new demands generated by technological innovation rules,a method system used to determine innovation demands was proposed under "the mixed mode integrated market-pull and technology-driven",In this method system,the technology-feasible degree of innovative ideas was obtained by integrating Intuitionistic Fuzzy Sets (IFS) with Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS);the matched-degree between innovative ideas and market requirement was got by integrating TOPSIS with Gray Relational Analysis (GRA);a new method called vector-cosine was proposed which counted innovation ideas as vectors and represented them by two parameters of length and angle;the integrated organic degree between technology and market demand was calculated through projection-cosine value,and innovation demands were determined.A case study of washing machine's innovation design was provided to illustrate the validity of proposed approach.
