This project proposes Constrained Geometric Morphing (COGEM) as a novel generic mechanical design framework that will allow intuitive geometric modifications of arbitrarily complex baseline designs via shape morphing (deformation) procedures while preserving key prescribed geometric parameters. The goal of the project is to provide new theoretical and computational foundations for COGEM to enable intuitive and efficient geometric modifications of existing baseline designs to satisfy new functional requirements. The anticipated approach will lead to formal foundations for the geometric design of product families of complex mechanical systems, and will be supported by the development of computational algorithms. More broadly, the fact that every parametric update can be expressed in terms of a sequence of shape deformations implies that constrained shape deformation can be thought of as a generalization of parametric design, and could potentially lead to the emergence of a new discipline. The proposed research will enable students to quickly explore the design spaces above and beyond the current capabilities of parametric solid modeling technology. At the same time, the integration of geometric reasoning and algorithmic design into the engineering curriculum will help develop a new generation of engineers that will be able to exploit the potential of modern computer aided design technology in conjunction with traditional mechanical engineering expertise.

该项目提出了受约束的几何形态（COGEM）作为一种新型的通用机械设计框架，该框架将通过形状变形（变形）程序对任意复杂的基线设计进行直观的几何修饰，同时保留密钥规定的几何学参数。该项目的目的是为COGEM提供新的理论和计算基础，以实现现有基线设计的直观有效的几何修饰，以满足新的功能要求。预期的方法将为复杂机械系统的产品家族的几何设计带来正式的基础，并将通过计算算法的开发来支持。更广泛地说，每个参数更新可以用一系列形状变形表示，这一事实意味着，可以将约束形状变形的限制视为参数设计的概括，并可能导致新学科的出现。拟议的研究将使学生能够快速探索超出当前参数固体建模技术功能的设计空间。同时，将几何推理和算法设计集成到工程课程中将有助于开发新一代的工程师，这些工程师将能够与传统的机械工程专业知识一起利用现代计算机辅助设计技术的潜力。
