【摘要】：產品設計缺陷形成于設計過程，任一階段處理不當都會對產品的功能和性能產生不同程度的影響，從而產生設計缺陷。設計開發(fā)過程的概念設計階段，對產品最終質量的形成起到決定性作用，可能導致出現產品的功能缺陷和結構缺陷。本文從技術和管理的角度，定性和定量兩方面相結合全面分析了硬件產品概念設計階段缺陷與缺陷因素間的關系，并提出了概念設計缺陷的評估方法和控制措施。 論文首先對產品設計缺陷的定義入手，，分析了硬件產品設計開發(fā)模式，從過程管理的角度分析了概念設計階段缺陷的形成機理；詳細研究了硬件產品概念設計過程中的各基本設計活動，并運用過程方法的思想，分析概念設計過程中各活動的輸入、輸出、轉換活動所需資源和所處環(huán)境、監(jiān)測評價等六要素，即概念設計缺陷的影響因素，通過概念設計活動與影響因素的關系構建設計缺陷過程要素模型，并通過模糊層次分析法對模型進行定量描述。從設計缺陷形成過程的角度，根據設計活動間不同的時序關系，分析了設計活動內和活動間的缺陷，最終確定設計活動對概念設計缺陷的影響程度，并以手持式打釘機的部分概念活動為例，驗證該評估方法的有效性和可行性。以此為基礎，從設計過程層次和功能層次建立了硬件產品設計缺陷控制管理體系結構，基于產品設計活動間的關聯性，從活動本身和活動間關系兩方面提出了硬件產品設計缺陷的控制管理模式。 論文研究給出了基于過程方法的硬件產品概念設計階段缺陷的結構模型，實現了概念設計活動與缺陷因素的定性和定量研究，從設計活動的角度對概念設計缺陷評估，為設計缺陷的預防和控制提供科學決策。
[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.
