【摘要】：产品设计缺陷形成于设计过程，任一阶段处理不当都会对产品的功能和性能产生不同程度的影响，从而产生设计缺陷。设计开发过程的概念设计阶段，对产品最终质量的形成起到决定性作用，可能导致出现产品的功能缺陷和结构缺陷。本文从技术和管理的角度，定性和定量两方面相结合全面分析了硬件产品概念设计阶段缺陷与缺陷因素间的关系，并提出了概念设计缺陷的评估方法和控制措施。论文首先对产品设计缺陷的定义入手，，分析了硬件产品设计开发模式，从过程管理的角度分析了概念设计阶段缺陷的形成机理；详细研究了硬件产品概念设计过程中的各基本设计活动，并运用过程方法的思想，分析概念设计过程中各活动的输入、输出、转换活动所需资源和所处环境、监测评价等六要素，即概念设计缺陷的影响因素，通过概念设计活动与影响因素的关系构建设计缺陷过程要素模型，并通过模糊层次分析法对模型进行定量描述。从设计缺陷形成过程的角度，根据设计活动间不同的时序关系，分析了设计活动内和活动间的缺陷，最终确定设计活动对概念设计缺陷的影响程度，并以手持式打钉机的部分概念活动为例，验证该评估方法的有效性和可行性。以此为基础，从设计过程层次和功能层次建立了硬件产品设计缺陷控制管理体系结构，基于产品设计活动间的关联性，从活动本身和活动间关系两方面提出了硬件产品设计缺陷的控制管理模式。论文研究给出了基于过程方法的硬件产品概念设计阶段缺陷的结构模型，实现了概念设计活动与缺陷因素的定性和定量研究，从设计活动的角度对概念设计缺陷评估，为设计缺陷的预防和控制提供科学决策。
[Abstract]:Product design defects are formed in the design process, any stage of improper handling will have a different degree of impact on the function and performance of the product, resulting in design defects. Play a decisive role in the formation of final product quality, may lead to product functional defects and structural defects. The relationship between defects and defect factors in conceptual design stage of hardware products is analyzed in both qualitative and quantitative aspects, and the evaluation method and control measures of conceptual design defects are put forward. Firstly, the definition of product design defect is introduced, and the hardware product design and development mode is analyzed, and the forming mechanism of the defect in conceptual design stage is analyzed from the point of view of process management. The basic design activities in the process of conceptual design of hardware products are studied in detail, and the input, output, resource and environment of each activity in the process of conceptual design are analyzed by using the idea of process method. Six factors, such as monitoring and evaluation, namely the influencing factors of conceptual design defects, are used to construct the process factors model of design defects through the relationship between conceptual design activities and influencing factors. From the point of view of the forming process of design defects, according to the different time series relations between design activities, the defects within and between design activities are analyzed. Finally determine the influence of design activities on conceptual design defects, and take some conceptual activities of hand-held nail machine as an example to verify the effectiveness and feasibility of the evaluation method. The architecture of defect control management in hardware product design is established from the level of design process and function, which is based on the relevance of product design activities. The control management mode of hardware product design defect is put forward from two aspects: activity itself and the relationship between activities. In this paper, the structural model of the defects in the conceptual design stage of hardware products based on the process method is presented, and the qualitative and quantitative study of the conceptual design activities and defect factors is realized. The defects of conceptual design are evaluated from the point of view of the design activities. Provides the scientific decision for the design flaw prevention and control.
