Enterprises face increasing challenge in the designing stage which needs to turn the customer’s needs into technical characteristics. In order to enhance the competitiveness of products, a demand-oriented innovative design model was proposed. This model integrates user demand accessing, technology feature mapping, quality function deployment and innovative solutions generation. During the design stage, designers need to match the acquired customer requirements to corresponding technical features, then apply House of Quality (HOQ) for building the mapping of user requirements to the technical features, analyzing the correlation and weights, and then with the aid of the theory of inventive problem solving (TRIZ) to resolve corresponding technical contradictions. Finally, an innovative solution of car steering demonstrated the feasibility of the demand-oriented innovative design model.

Keywords: Innovative design, QFD, technical characteristics, TRIZ, user requirements.
