Abstract: As the consumer individualization is becoming stronger and the customer demand is changing more frequently,the traditional manufacture-active design pattern cannot meet the demands of the present age.It is widely acknowledged that the individualization can be really realized if the consumer could participate in the product design process.At present,the large-scale consumer participation in product design process through Internet is quite prevalent,but the design methodology and theoretical foundation have never been concerned by previous studies.Aiming at these problems,an open design method of large-scale consumer participation was proposed,which could accurately map the consumer's fragmentation and fuzziness requirements to the product model.First of all,based on the similarity recommendation process,consumers were helped to improve their solutions.At the same time,the consumer's self-organizing clustering was realized.Then,based on rough set theory,the convergence decision of a large number of consumer solutions was realized.Finally,taking the washing machine design as an example,the open design process of large-scale consumer participation was illustrated,and the feasibility of the method was verified.
