集成AHP/QFD/AD的产品设计方法研究

目的针对以用户需求为驱动的产品设计模式,完善产品设计方法流程,更有效地理解用户需求,提高产品设计效率和质量。方法使用层次分析法确定用户需求权重,将用户需求及权重输入质量屋,对用户需求与设计需求的相关关系度进行量化评价,构建用户需求与设计需求相关关系矩阵,确定各项设计需求重要度,完成用户需求到设计需求的转化,以相对重要度较高的设计需求定义功能域,进行功能域与物理域之间的映射,利用独立性公理和信息公理进行设计参数分析和设计方案评价。结论构建了一种集成层次分析法、质量功能展开和公理化设计的产品设计方法,对用户需求权重进行了更准确的分析,完善了质量功能展开后续的方法流程,并以板栗采收机概念设计为例进行了应用验证,应用结果表明该方法能够有效地指导产品设计过程,提高产品设计效率和质量。

Product Design Method Integrating AHP/QFD/AD

The work aims to improve the product design method flow in view of the product design mode driven by user demand, so as to understand user demand more effectively, and improve product design efficiency and quality. Analytic hierarchy process was used to determine the weight of user demand, input the user demand and weight into the house of quality, make quantitative evaluation on the correlation between user demand and design demand, build the correlation matrix between user demand and design demand, determine the importance of each design demand, complete the transformation from user demand to design demand, define the functional domain with the relatively important design demand, conduct the mapping between functional domain and physical domain and use independence axiom and information axiom to analyze design parameters and evaluate design schemes.A product design method integrating analytic hierarchy process, quality function deployment and axiomatic design is constructed. The weight of user demand is analyzed more accurately, and the follow-up process of quality function deployment is improved. The application of the method is verified by the case of conceptual design of chestnut harvester. The application results show that the method can effectively guide product design process and improve product design efficiency.
