In order to meet the users’ needs,the demand-oriented innovation design model was proposed and the process of designing the steering was demonstrated based on this strategy.The demand-oriented innovative design model integrated user demand accessing,technology feature mapping,quality function deployment and innovative solutions generation.During the design stage,designers acquire the users’requirements and the corresponding technical features,apply House of Quality (HOQ) to build the mapping of requirements to technical features,and analyze the correlation and weights,then resolve corresponding technical contradictions with the aid of theory of inventive problem solving (TRIZ).In this strategy,the steering system meets the users’ needs and achieves the functions of power assisted steering and road feedback by making use of hydraulic system.
