Abstract

With the influence of rational consumption and low carbon life, people like high-quality and durable products. Now some products are not fit for the varied requests of children, pregnant and other people .So the theory of the user life cycle design (ULCD) is proposed in this paper. Four kinds of ULCD design methods are summarized. Those are design methods of alternations in human body dimension, motor function, human cognition and synthetical functions. The ULCD process is described in this paper. So the method of decision-making is explained in the process of ULCD and proved by the case of baby product.
