项目摘要

Different aspects of the use of parametric 3D CAD software, e. g. "circumscribed thinking" or the WIMP user interface, limit the creativity of the product developer and consequently the scope of the preliminary embodiment designs. Thus the software does not represent an optimal tool for form synthesis at early embodiment design stage. Simultaneously the early, computer-aided creation of preliminary embodiment designs incorporates enormous potential to improve the product quality. In terms of frontloading, the product as well as its functionality and quality could be ensured earlier in the design process, if the geometry information - in contrast to hand-drawn sketches - would be available in a computational form. Based on this consideration the research question of this project emerges: How must a computational method look like to support the product developer in creative form design at early embodiment design stage?A frequently used approach is the utilisation of natural forms of interaction in Virtual Reality. Although research with the objective to integrate CAD and VR – especially in context of freeform creation – exists, no attention is paid to the interaction through natural, tacit knowledge based user interfaces as well as to form design of preliminary embodiment designs starting with effective areas and effective bodies. Therefore the central objective of the two-year research project is to provide a universal method that allows an earlier computer support of the product developer in the creative preparation of form design studies and preliminary embodiment designs through a functional procedure in terms of VDI 2221 Step 5. The method contains a modular kit with form design elements. These elements serve as basic building blocks for the creation of preliminary embodiment designs. For the interaction with virtual models, an existing user interface for natural finger interaction is used. This was implemented in the research demonstration system "i 3 VR" at the Department of Mechanical Engineering of the Friedrich-Alexander-Universität Erlangen-Nürnberg. In order to achieve the central objective, four sub-objectives are necessary. Thereof the content of the four work packages is derived. The structure of the work programme and work packages follows the Design Research Methodology (DRM) from Blessing and Chakrabarti.The expected scientific finding resulting from this research project is evidence about the suitability of a computer-aided method for form synthesis of preliminary embodiment designs using natural forms of interaction and stereoscopic visualisation.

使用参数化 3D CAD 软件的不同方面，例如“限制思维”或 WIMP 用户界面，限制了产品开发人员的创造力，从而限制了初步实施例设计的范围，因此该软件并不代表最佳的形式工具。同时，早期实施例设计的早期计算机辅助创建具有提高产品质量的巨大潜力，可以在早期确保产品及其功能和质量。设计过程中，如果几何信息（与手绘草图相比）能够以计算形式提供，基于此考虑，该项目的研究问题出现：计算方法必须如何支持产品开发人员的创意。早期实施设计阶段的形式设计？一种常用的方法是在虚拟现实集成中利用自然交互形式，尽管存在以 CAD 和 VR 为目标的研究（尤其是在自由形式创建的背景下），但没有注意到这一点。通过自然的、基于隐性知识的用户进行交互因此，这个为期两年的研究项目的中心目标是提供一种通用方法，使产品开发人员能够在创造性准备过程中获得早期计算机支持。通过根据 VDI 2221 步骤 5 的功能程序进行表单设计研究和初步实施例设计。该方法包含具有表单设计元素的模块化套件，这些元素用作创建初步实施例设计的基本构建块。虚拟模型，用于自然手指交互的现有用户界面这是在埃尔兰根-纽伦堡弗里德里希-亚历山大大学机械工程系的研究演示系统“i 3 VR”中实现的。为了实现中心目标，有四个子目标。四个工作包的内容是根据 Blessing 和 Chakrabarti 的设计研究方法 (DRM) 得出的。该研究项目的预期科学发现证明了这一点。使用交互的自然形式和立体可视化进行初步实施例设计的形式合成的计算机辅助方法的适用性。
