Abstract: To avoid the innovative ideas with radical potential being killed in the conventional evaluation process of enterprises and to improve the possibility of the generation of radical innovation,a quantitative evaluation method for the identification of radical innovation ideas in the conceptual design stage was proposed.Based on literature analysis,a set of potential characteristic factors for radical innovation in conceptual design stage was constructed according to the change degree of product itself.By comparing the differences between innovative product cases and mainstream products,the binary quantitative characterization of potential characteristic factors was carried out,and the effective characteristic factors and weights were determined based on the correlation analysis of quantitative results.A radical innovation idea identification model was built based on the similarity matching between innovative ideas and radical innovation case data,and a corresponding computer-aided identification system was developed.The feasibility and effectiveness of the identification method were verified by a series of cases.

Key words: radical ideas identification, radical innovation, concept design phase, similarity matching, product design
