【摘要】 产品设计的水平和能力体现了一个国家和地区工业的创新能力和竞争能力。产品概念设计(Product Conceptual Desing,简称PCD)最能体现设计者聪明才智,是产品创新的核心,具有设计空间大、设计成本低的特点,日益受到人们的高度重视。模块化设计(Modular Design,简称MD)技术以其能缩短产品开发周期,快速响应市场变化,相对延长产品生命周期等优点,得到越来越广泛的应用。绿色制造(Green Manufacturing,简称GM)技术是实现生态工业和社会可持续发展的最佳途径。与清洁生产主要考虑生产对环境与人体影响不同,GM要求在产品的设计和制造过程中综合考虑产品全生命周期中每个环节,从而实现产品全生命周期对人体健康、环境影响最小、资源利用率最高,因而近年来日益受到社会各方面的极大关注。绿色设计(Creen Design,简称GD)作为近年来适应这一需要而兴起的一个现代新的设计理念、设计理论与设计方法,其研究技术正待发展与完善。本文旨在研究绿色模块化设计(Green Modular Design,简称GMD)技术与方法及其在产品概念设计(PCD)中的应用。研究了将模块化设计(MD)和绿色设计技术(GD)相结合应用于产品概念设计(PCD)的过程机理,建立了适合于计算机处理的用于产品概念设计的系统模型(包括用户需求模型、产品功能模型、概念产品结构模型、绿色评价模型、模块化评价模型),根据产品绿色模块化设计技术与方法研究了产品概念设计的系统模型,并以家用冰箱的箱体设计过程为例,分析了绿色产品概念设计的基本流程。分析结果表明:将模块化设计方法与绿色设计方法相结合用于概念设计,在方法上是切实可行的,并有建模方便、概念清晰、推理明确等特点,但要开发出实用性较强的软件还有大量的基础性工作要做,需要许多技术人员来共同努力。主要内容包括:1.从多方面、多角度对模块化设计、绿色设计、概念设计的研究现状进行了分析,介绍了一些典型的研究实例、研究方法与技术。简要分析了现有设计中存在的问题,提出了本文要着重解决的若干问题。2.从计算机信息处理的角度分析了产品设计一般过程,着重分析了概念设计的设计过程,总结了概念设计的特点,分析了绿色设计、模块化设计、概念设计的实质,确立了用模块化绿色设计方法进行产品概念设计流,建立了表达方便、易于处理的模块结构模型。3.采用系统建模理论与方法,建立了适合于计算机信息处理的产品绿色模块化设计的概念设计系统模型,即概念产品模型,其中包括:用户需求模型、产品功能模型、概念产品结构模型以及产品绿色特性评价模型、模块特性评价模型;4.研究了产品模块化绿色概念设计的各个模型间的相互关系,提出了动态需求的概念,建立了需求驱动和功能驱动两种映射方法,完成了从用户需求到产品功能再到概念产品结构的映射求解。5.论文最后以家用冰箱的箱体设计过程为例,分析了绿色产品概念设计的基本流程,对本论文中采用的一些设计方法作了进一步的解释和描述。最后,提出了本文尚待解决的若干问题,以及本文相关的计算机辅助概念设计领域的一些重要问题和发展方向。更多还原

【Abstract】 The level and ability of product design is the embodiment of a country or regions innovation and competition. Being the key element of innovation,the Product Conceptual Design (PCD)has gained more and more recognition. PCD has the advantages of having the biggest design space,low design cost and can mostly reflect the intelligence of the designers.Whether the product conceptual design is successful determines the success design of the product. The Modular Design(MD) has been applied widely because it could shorten the time of the productdeveloping cycle,respond quickly to the changing of the market and lengthen the life cycle of products. The Green Manufacturing (GM) technology is the best way to realize ecological industry and sustainable social development. Different from the clean product manufacturing,Which mainly focus on its influences on environment and humanbeing,GM requires considering each step of the product life cycle systematically in the processes of Product design and manufacturing. It takes the minimum influence on health and environment and the highest utilization ratio of natura1 resources as its design goals. It also brings us the great concerns of different social fields day by day. The Green Design (GD) which meets the requirements of those purposes,is a newly modem design idea. design theory and design method in recent years; its design technology and method is under developing . This dissertation aims at the study of the technology and method of the Modular Green Design (MGD) and its application in PCD. Its tudies the design Process schema of PCD by combining MD and GD techniques,whlch is called MGD for PCD. Asystematic model was proposed for computer-aided PCD including the User Requirements Model(URM),the Product Functions Model(PFM),the Conceptual product Structure Mode(lCPSM),the Products Green Properties Evaluation Mode(lPGEM) and the Modules Properties Evaluation Model (MPEM). The general process of PCD is realized and a prototypical app1ication program on computer aided PCD is developed according to the author ’s researching work on the MGD and PCD. The results of the study shows: the MGD design techno1ogy used for PCD is useful and feasible. The Proposed method has many characters,such as modeling is convenient,concept is clear and deducing has definitely results. But developing an applicable app1ication Program needs a 1arge amount of basic work to do,efforts of a technical staff maybe needed.This paper will probe into some items showed as below:Firstly,research progresses in MD,GD and PCD are analyzed from several aspects,Some typical research examples,research approaches and technologies are introduced,the Existing problems in PCD design are briefly anaIyzed,several research problems are proposed,and Parts of which will be solved emphaticalIy in the dissertation·Secondly, the process of product design is analyzed from the view of computer Information processing , especially the Process of PCD; The advantages and the essence of MGD and PCD are analyzed; and the general process of MGD for PCD,which suitable for computer information processing is established.Third1y,by the use of the system modeling theory and technology the MGD’s system model for PCD , Which is suitable for computer information Processing is built,and its sub-modules include URM,PFM,CPSM,GPEM and MPEM.Fourth1y,the relationships between MGD and PCD are studied,dynamic user requirement module is proposed,and basing on URM and PFM,two kinds of mapping methods,which solve the design problem and give out the conceptual product’s structure are discussed.Finally,a prototypical application program of MGD for PCD is developed based on the Theories which are proposed by the author.At the end of this dissertation,a brief conclusion is given,and some relevant researching work in the future is presented.更多还原
