基于象元的形态创新方法及其应用研究

The diversification, specialization and taste-self of user requirements, are pushing the personalized customization into a hotspot in manufacturing research and application. Consumers-centered products form personalized customization is a e difficulty but key problem..This study will seek a consumer-oriented method in product's form expression and the modelling innovation process showed in a more direct, convenient, easily-operated and interaction experience way..Refer to the concept and connotation of traditional Chinese “symbol”as well as the relative thoughts from modern morphology and semiotics, this paper puts forward the concepts in “meta symbol”. That means a complex form can be broken down into a variety of morphological characteristics, which can be represented as different meta symbols. With meta symbol and language logical characteristic in all kind of deformation needs of customers, this article has presented and built three relation operations and their rules of replace operation, merge operation and interpolation operation. Meta symbols and their operations are basic to the method “Meta Symbol Adjusting”. The MSA jumps out of the body of point, line and plane to control in the form of 3d virtual model of CAID traditional ideas, so as to reduce the 3d integrated deformation of learning difficulty and complexity of operation..As a result of above research, this study puts forward a fast wheel innovation system on line, and shows the APP design. Through with the intuitive and simple operation, users quickly get the satisfactory results as well as the correlative information.

本研究旨在探寻一种基于CAFD技术平台的、面向消费者使用的新型形态表达方法，用以实现直观、便捷、易操作的、具备良好设计交互体验的产品形态创新过程，从而实现消费者主导的个性化形态定制目的。参考中国古文论中“象”概念及现代形态学相关思想，本研究提出“象元”概念：描述物体形态特征变化种类与程度的单元。以二维图形符号为表现形式，象元具有可视性、确定性、定量性、转换性和三维形态关联性。象元构成是形态变化特征基因，象元运算是形态特征转化与演变的依据和媒介。象元构成与象元运算是象元调型功能在CAFD平台实现的理论与方法基础。象元调型法跳出以点、线、面、体来调控三维虚拟仿真形态的传统CAID造型思路，从而降低三维形态创造过程的学习难度和操作复杂度。最后将象元调型法应用轮毂私人定制手机APP用户端设计。通过直观、简单的操作，快速获得不同轮毂形态调整方案，从而快捷、高质量地实现轮毂产品的线上个人定制。

随着网络化制造的不断发展，以消费者为主导的定制服务逐步成为产品服务的主流方式，尤其是产品形态在线定制化对服务型制造企业有着重要意义。现有产品创新与设计方法创新也逐渐从创意思维引导向计算机辅助设计引导转变。本研究旨在探寻一种基于CAFD技术平台的、面向消费者使用的新型形态表达方法，用以实现直观、便捷、易操作的、具备良好设计交互体验的产品形态创新过程，从而实现消费者主导的个性化形态定制目的。. 项目着眼于产品形态创新设计方法与平台建设，通过将“象” 的概念与现代形态学结合，建立象元表达法展现产品形态特征，并以象元运算建立形态特征间的关联。在此基础上构建了一系列轮毂形态个性化定制设计方法，从而满足消费者和轮毂制造企业的多元化需求。. 运用象元形态设计法，构建了基于象元运算的轮毂形态设计方法。同时融合可拓学内容，探索了一种满足用户个性化需求的快速生成的产品智能设计方法。基于轮毂企业延续品牌特征的需求，创建了一种产品品牌DNA特征转录的轮毂形态定制方法。为扩展轮毂形态库品类，将参数化引入轮毂形态设计中，构建汽车轮毂参数化仿生形态模型。针对轮毂复杂组合形态美感一致度判定问题，提出了一种“审美匹配临界值法”，构建出基于感知匹配的轮毂形态定制优荐系统。在轮毂造型构建后需进行结构优化分析，为此构建了基于SolidThinking的轻量化轮毂结构形态优化路径，同时建立了基于象元的个性化轮毂定制流程与技术框架，并获批“轮毂形态在线设计系统V1.0”和“轮毂造型定制平台V1.0”两项软件著作权，从而实现轮毂形态个性化在线定制，为后续轮毂3D云设计技术研究奠定基础。. 相关研究的进展与突破，创造性地改变产品造型设计的过程和方法途径，提升智能化造型设计水平。定制平台与在线设计模块协同创新，初步实现3D设计批量化和自动化，有效提升了轮毂企业设计人员工作效率。创新方案应用于实际生产取得了良好的产业收益，实现了项目研究预期目标。
