Abstract: For the innovative solution issue of product evolution direction in the early stage of low carbon design,an innovative design method of low-carbon product was proposed with evolution potential and Theory of inventive problem solving (TRIZ)evolution theory.A recursive model of carbon emission algorithm based on function-structure-feature was constructed,and the characteristics of low carbon design were researched.Types and expression way of evolution requirements of low carbon products were analyzed,requirements mapping was driven by environmental quality function deployment and rough set,and the extraction of design features of low carbon evolution was identified with evolution potential value.TRIZ innovation principles,evolution route and design knowledge were related to the design features of low carbon evolution,and the evolution direction and strategy was given to support low carbon design of the updating and upgrading of products.The design case of dishwasher verified the feasibility of the proposed method.
