【摘要】：世界市场正在步入个性化消费的时代,能够彰显自我独特个性的定制型产品逐渐获得消费者的喜爱。用户需求的多样化、特殊化和自我品味化,使得个性化定制成为制造业研究与应用的热门。目前相关研究大部分是从企业发展战略,以及实施运作等角度来说明定制生产和定制化模式的重要性和可行性。面向消费者的定制方式和方法研究最近几年才出现,消费者对定制产品的认知特点、参与定制能力、定制方法适应、以及定制操作过程的愉悦交互体验等为主题的研究相对较少。本研究旨在寻求一种适于消费者使用的产品形态设计方法,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定制过程。这也是本论文的重点研究目标。参考中国古文论中“象”的概念内涵,以及现代形态学的相关思想,本文提出“象元”概念,用以表征复杂物体形态具有的多种形态特征。利用象元思想完成形态特征的分类与变化程度界定。同时参考消费者对各种形态变化需求的特点,本文提出并建立象元的三种关系运算:替换运算、合并运算和插值运算,并规定各自运算法则。象元分类构成与象元运算是基于象元的形态设计法实现的基础和前提。依据象元分类与构成,以象元作为调节因子,利用三种运算法则实现象元变换,借助一定CAID技术平台完成象元控制的相应三维形态调整,通过一定交互平台实现直观、便捷的在线形态设计过程,称为象元形态设计法。象元形态设计法跳出以点、线、面、体来调控三维虚拟仿真形态的传统CAID造型思路,降低三维形态设计的学习难度和操作复杂度。以汽车轮毂产品为例,论文阐述了轮毂产品的象元提取方法,轮毂象元分类构成以及轮毂象元三种具体运算法则。借助多种CAID工具平台,本文提出象元形态设计法的实现路径和过程。基于曲面建模软件RHINO和参数化建模插件GRASSHOPPER,进行软件二次开发,将象元运算转化为点阵控制因子,以点阵图形控制形态整体变型进而实现形态设计的过程。并进一步指出,轮毂局部形态变型可以在CREO软件中直接建模平台实现,而轮毂组合搭配变型可以利用三维可视化虚拟仿真平台VRP实现定包括色彩定制、图案定制,以及配车效果模拟显示等需求。最后,本文将象元形态设计法应用于个性化轮毂形态定制系统的开发。构建了基于象元的个性化轮毂定制流程与技术框架,重点针对整体形态变型定制、局部微量变型定制和组合搭配需求定制进行了定制方式的设计。设计并实验了轮毂个性化定制手机APP用户端的界面、使用和操作过程。用户通过直观、简单的操作,快速获得不同轮毂变型方案结果,从而快捷、高质量地实现轮毂产品的线上个人定制。APP实验进一步验证了象元形态设计法的易用性和好用性。这种灵活、方便、快速的易学易用型轮毂形态定制系统打通了制造企业与用户端之间的沟通盲区,构建了二者之间体验与交互式的交流平台。
[Abstract]:The world market is entering the era of personalized consumption, and the custom-made products that can highlight the unique personality of the world have gradually gained the love of consumers. The diversification, specialization and self taste of the user's needs make the personalized customization become a hot topic in the research and application of the manufacturing industry. The importance and feasibility of customizing production and customization mode are illustrated and implemented. Consumer oriented customization methods and methods have only appeared in recent years, consumers' cognitive characteristics of customized products, customization ability, customization method adaptation, and joyful interactive experience of customizing operation process are the subject of research. Relatively few. This study aims to seek a product form design method suitable for consumer use to achieve visual, convenient, easy to operate, and well designed interactive experience in the product form customization process. This is also the focus of this paper. In this paper, the concept of "elephant element" is proposed in this paper to characterize the various morphological features of complex objects. Using the idea of the image element to complete the classification and degree of change of morphological features. At the same time, referring to the characteristics of consumers' needs for various forms of change, this paper puts forward and establishes three relation operations of the image element: replacement operation and combined transportation. Calculation and interpolation operation, and stipulate their respective operation rules. The image element classification and image element operation are the basis and premise based on the morphological design method based on the image element. According to the image element classification and composition, image element is used as the adjusting factor, the image element transformation is realized by three algorithms, and the corresponding three-dimensional control of the image element is completed with the help of a fixed CAID technology platform. Shape adjustment, through a certain interactive platform to achieve intuitive, convenient online form design process, called the image element form design method. Like the element shape design method to jump out of the point, line, surface, body to control the three-dimensional virtual simulation form of traditional CAID modeling ideas, reduce the learning difficulty and operation complexity of three-dimensional shape design. In this paper, the method of image element extraction, hub image element classification and hub image element are described in this paper. With the help of a variety of CAID tool platforms, the path and process of the image element form design method are proposed in this paper. Based on the surface modeling software RHINO and the parameterized modeling plug-in GRASSHOPPER, the software is developed for two times. The image element operation is transformed into a lattice control factor, and the shape design is realized by controlling the shape of the shape with the dot matrix figure. Furthermore, it is pointed out that the local shape transformation of the hub can be realized directly in the CREO software, and the hub combination and collocation variant can make use of the three dimensional visual virtual simulation platform VRP to realize the fixed color. Color customization, pattern customization, and simulation display of car matching effect. Finally, the image element shape design method is applied to the development of personalized hub shape customization system. A personalized hub customization process and technical framework based on the image element is constructed, focusing on the overall shape change customization, local micro variant customization and combination and matching needs. Design and experiment the interface, use and operation process of the APP user terminal of the hub personalized custom handset. The user can quickly obtain the results of different hub variant schemes through intuitionistic and simple operation, thus further validates the online personal customization.APP experiment of the hub products. The easy-to-use and good use of the image element form design method. This flexible, convenient, fast and easy to learn and easy to use hub shape customization system has opened the communication blind area between the manufacturing enterprise and the user side, and constructed the experience and interactive communication platform between the two.
