基于需求和解决冲突的创新设计策略

Strategy of Innovative Design Based on Requirements and Conflicts Solving

为了使产品更好地满足用户的需求,提出一种面向用户需求的产品创新设计模型,并对车辆转向器进行创新设计。这个模型集成了用户需求获取、技术特征映射、质量功能配置和创新方案生成功能。面向用户需求的创新设计,首先获取用户需求并进行规范化表达,并获取相关的技术特征,再利用质量工程屋(HOQ)工具构建用户需求到技术特征的映射和权重关系。技术特征存在耦合矛盾和自有矛盾,针对不同类型的技术矛盾,分别利用发明问题解决理论(TRIZ)中相应的创新工具来解决。运用这种策略,在车辆转向器设计中,分析用户需求,通过引入新型的液压系统,实现助力转向和路感反馈。

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.
