六西格玛设计与TRIZ集成和应用研究

河北工业大学硕士学位论文i六西格玛设计与TRIZ集成和应用研究摘要DMADV是以6σ质量水平为目标的设计方法。DMADV主要在产品、流程需要重新设计，或需要对产品、流程进行重大的突破性改进时使用，它按照合理的流程、运用科学的方法准确理解顾客需求，开发出创新性强的产品，实现6σ甚至更高的质量水平。众多国内外大型企业通过实施DMADV项目，提高了企业的竞争力，为企业带来了巨大的经济效益。在实施DMADV过程中，设计人员常常采用传统方式获取和分析顾客需求，这种方式偏重于改善已有需求，而很难提出潜在的新需求。在确定产品设计概念时，设计人员往往因为缺少一种用来生成、评价、选择产品的设计概念的系统化、结构化的方法或流程而导致产品概念缺乏创新性、竞争力。本论文在分析和研究DMADV的基础上，针对在实施DMADV过程中的测量顾客需求阶段及分析产品设计概念阶段存在的一些不足，将TRIZ中的需求进化定律、技术进化定律及其路线、冲突解决原理、物质—场分析及76个标准解、9窗口法等设计方法及工具集成到DMADV中。应用需求进化定律获取、分析已有需求和提出新需求，应用技术进化定律确定创新性高的产品设计概念，并通过冲突解决原理改善产品设计概念，进而建立基于TRIZ的需求进化定律和技术进化定律与DMADV集成模型。本论文首先介绍了DMADV以及TRIZ的需求进化定律、技术进化定律、冲突解决原理、物质—场分析、76个标准解等设计方法及工具，然后将TRIZ的相关工具、方法与DMADV集成，建立基于TRIZ的需求进化定律和技术进化定律与DMADV集成模型，最后通过对新型指甲刀概念设计和塑料导爆管自动切割机的改进设计对DMADV与TRIZ的集成流程模型进行验证。关键词：六西格玛设计，DMADV，TRIZ，需求进化定律，技术进化定律，冲突解决原理DMADV与TRIZ集成的应用研究iiRESEARCHONINTEGRATEDANDAPPLICATIONOFDESIGNFORSIXSIGMAANDTRIZABSTRACTDMADVisadesignmethodbasedon6σqualitylevel.DMADVismainlyusedinproductneedtoredesignorbreakthroughimprovement.It'saccordingtoreasonableflows,usingscientificmethodstoaccuratelyunderstandneeds,developinginnovativeproducts,toachieve6σevenahigherqualitylevel.ManylargeenterprisesathomeandabroadthroughtheDMADVprojects,improvethecompetitiveness,andbringtheenormousbenefitstoenterprises.IntheprocessofDMADVimplementation,designersoftenadoptthetraditionalwaytoobtainandanalyseneeds.Thiswayfocusonimprovingtheexistingneeds,butitisdifficulttoputforwardnewneeds.Indeterminingtheconcepts,designersoftenaslackingasystematic,structuralmethodorflowusedtogenerate,evaluation,selectionconcepts,causeconceptslackofinnovation,competitiveness.BasedontheanalysisandstudyDMADV,aimingatsomeshortagesintheMeasureandAnalyse,integratetheLawsofneedsevolution,Lawsoftechnologicalevolution,principleofcontradiction,Su-FieldAnalyse,76StandardSolutions,Multi-screenapproachintoDMADV.ApplicationLawsofneedsevolutiontoobtainandanalyseexistingneedsandputforwardnewneeds,applicationLawsoftechnologicalevolutiontodeterminedesignconcepts,throughprincipleofcontradictiontoimproveconcepts,thensetupDMADVandTRIZintegratedmodelbasedoncoordinationofLawsofneedsevolutionandLawsoftechnologicalevolution.ThispaperfirstlyintroducesDMADVandtherelatedtoolsofTRIZ,andthenintegrateDMADVandTRIZ,setupDMADVandTRIZintegratedmodel.Finally,throughthenovelnail-clipperconceptdesignandtheautomaticshearingmachineforthenoneltubetoverifytheintegrationmodelofDMADVandTRIZ.KEYWORDS：DesignforSixSigma,DMADV,TRIZ,Lawsofneedsevolution,Lawsoftechnologicalevolution,principleofcontradiction河北工业大学硕士学位论文iii目录第一章绪论...................................................1§1-1课题研究背景........................................................................................................................................1§1-2DFSS研究现状......................................................................................................................................11-2-1国外DFSS研究现状.......................................................................................................................21-2-2国内DFSS研究现状.......................................................................................................................21-2-3目前DFSS存在的不足...................................................................................................................3§1-3课题研究的意义....................................................................................................................................5§1-4课题研究的主要内容............................................................................................................................61-4-1课题研究的主要内容......................................................................................................................61-4-2论文的组织结构..............................................................................................................................6§1-5本章小结................................................................................................................................................7第二章六西格玛设计概述.......................................8§2-1引言........................................................................................................................................................8§2-2DFSS的产生与发展..............................................................................................................................8§2-3DFSS的定义..........................................................................................................................................92-3-1六西格玛的基本含义......................................................................................................................92-3-2DFSS的定义..................................................................................................................................10§2-4DFSS项目选择及团队组建................................................................................................................112-4-1DFSS项目选择.............................................................................................................................
