This paper adopts the methods of establish matrix list to concept design evaluation, to study the methods of establishing evaluational criteria and the methods of concept design evaluation. It reveals that it is necessary to evaluate the function, use, man-machine interface, physical structure and control, various technology, assembling handicraft, etc. for concept design evaluation. Concept design process exhibits characteristics of diverging, converging, diverging again, converging again, totally converging. The result shows valuation of concept schemes should be carefully chosen by ways of setting up target product model, matrix of standard decision-making, combining perceptual with reason judgement, schemes being improved and chosen. The evaluation should be carried out in such a way that it should take into account the economical value of the scheme and the promotion of the company’s competitiveness during the entire life cycle of the product.
