中文摘要:

      目的 为了满足客户的实际需求，缩短产品设计周期，避免传统设计方法生成产品结构的过程中易产生设计耦合的潜在问题。方法 以结构设计作为主要目的，提出一种基于公理设计的产品结构设计模型（Axiomatic Design Based Structural Design, ADBSD）。该模型在质量功能展开（Quality Function Deployment, QFD）的基础上，采用KANO模型的赋值计算规则，获得总体客户功能需求权重值，作为结构设计的总功能需求，输入公理设计框架流程中的“Z”字型映射中；并运用TRIZ技术冲突、发明原理等工具进行设计优化，在设计初期解决设计参数之间的冲突问题，得到完整的产品设计结构。结果 通过对小空间自走式消防装备进行设计研究，阐述了运用ADBSD进行产品结构设计的优势，验证了该方法的可行性。结论 该模型为产品创新设计过程提供了新思路和理论参考。

英文摘要:

      The work aims to satisfy the actual requirements of customers, shorten product design cycle and avoid the potential problem of design coupling in the process of generating product structure by traditional design method. Taking the structural design as the main purpose, an axiomatic design based structural design (ADBSD) model was proposed. Based on the quality function deployment (QFD), the value assignment calculation rule of KANO model was used to obtain the weight value of the overall customer function requirement. The weight value was used as the total functional requirement of the structural design to be entered into the “Z” font mapping in the process of axiomatic design framework. Technology conflicts, invention principles and other tools of TRIZ were used to optimize the design, solving the conflict between design parameters in the early stage of the product design, and a complete product structure design was obtained. The advantages of ADBSD for product structure design were explained and the feasibility of the proposed method was verified through the research on the design of self-propelled fire-fighting equipment in small spaces. The ADBSD model provides new ideas and theoretical references for the product innovation design process.
