User requirements play an important role in product design activities, and the accurate and full acquisition of user requirements is directly related to customer satisfaction with product design. Implicit requirements are potential, fuzzy and subjective. In this paper, a new implicit user requirements process method based on the cloud service platform is proposed to solve the difficulty of implicit requirements acquisition. The method initially collects user requirements data by the metaphor extraction technique on the cloud service platform. Then, the requirements data are clustered and mapped with product attributes. The mapping result is then visualized to intuitively guide product design and optimization. This method is a user-centered innovation paradigm implemented on the cloud service platform, which can realize collaborative design and resource sharing. Finally, an application case is performed to illustrate the method, and the result indicates that the method is effective and can be used in product design.
