This disclosure describes a method and design in producing the design of an article of manufacture that includes two or more components and the method satisfies the analytical representation of the boundary distance constraint between the shapes of the two components during the design. The disclosure includes providing a software program executing on a workstation that executes a number of steps that include: Providing the shape of a first component, the shape of a second component, and a boundary distance constraint. The disclosure includes the construction of a shape spectrum. The disclosure searches to find an arrangement of the shapes. The disclosure evaluates the boundary distance constraint to determine if the boundary distance constraint is satisfied. Further, the disclosure evaluates a subderivative of the shape spectrum. Additionally, the disclosure provides that the searching continues until the boundary distance constraint is satisfied, and when satisfied, the design is produced. |

1. A method to produce the design of an article of manufacture that further comprises two or more components of the article and that uses a software program executing on a workstation that satisfies the analytical representation of the boundary distance constraint between the shapes of the two components during the design of the article of manufacture, comprising:
providing a software program executing on a workstation, said workstation includes a processor, memory, and storage, said software program executes the following steps: providing the shape of a first component and providing the shape of a second component; providing a boundary distance constraint, said boundary distance constraint specifies the desired geometric relationship to be enforced between the shape of said first component and the shape of said second component; constructing a shape spectrum of the exterior boundary surface of closest approach associated with the shape of said first component, the shape of said second component, and said boundary distance constraint, wherein said shape spectrum is an analytical representation of the boundary surface of closest approach and forms the analytical foundation for evaluating said boundary distance constraint; searching to find an arrangement of the shape of said first component and the shape of said second component that satisfies said boundary distance constraint; evaluating said boundary distance constraint to determine if said boundary distance constraint is satisfied; evaluating a subderivative of said shape spectrum of the exterior boundary surface of closest approach associated with the shape of said first component, the shape of said second component, and said boundary distance constraint, wherein said subderivative is used in the evaluation of said boundary distance constraint and where the exterior boundary surface of closest approach is the shape that forms the geometric foundation for the step of evaluating said boundary distance constraint; wherein said searching to find an arrangement of the shape of said first component and the shape of said second component continues until said boundary distance constraint is satisfied, and when satisfied, said software program produces the design of the article of manufacture. |
