“…By form, Kahn meant the essence created by a certain relationship of elements within the whole. Thus, in practical terms, a design problem is characterized in terms of a set of requirements (specifications, goals, and constraints) such that if an artifact or system satisfies the requirements and is implemented according to the proposed design, the design problem will be solved [93], [76], [111].…”

“…In contrast to other design domains, such as software engineering and circuit design [113], a simple and obvious correspondence between specific functional requirements of the artifact and individual components in the design does not usually exist. Due to the tightly coupled and interacting nature of mechanical designs, reasoning from prior design cases is proving to be a suitable design methodology as opposed to direct "decompose and recombine" (or "generate and test") strategies that have successfully been utilized in VLSI design [116], [111]. Cases are the primary way in which engineering students are taught to design.…”

In this paper, we examine the logic and methodology of engineering design from the perspective of the philosophy of science. The fundamental characteristics of design problems and design processes are discussed and analyzed. These characteristics establish the framework within which different design paradigms are examined. Following the discussions on descriptive properties of design, and the prescriptive role of design paradigms, we advocate the plausible hypothesis that there is a direct resemblance between the structure of design processes and the problem solving of scientific communities. The scientific community metaphor has been useful in guiding the development of general purpose highly effective design process meta-tools [73], [125]. His research within engineering design focuses on developing methods to help the designer move from the conceptual phase to the realization of the physical device. To achieve this objective, he has developed the formal general design theory (FGDT), which is a mathematical theory of design. He has developed methods to solve routine design with group technology, genetic algorithms, and simulated annealing, to define computerized architecture, structure, and databases for the conceptual design process, and to develop a framework of logic decomposition and case-based reasoning methodology for mechanical design. He is also co-authoring, with O. Maimon, a book on the foundations of engineering design. Additional interests include real-time scheduling of flexible manufacturing systems, inventory management, risk and decision analyses, and group technology. His papers have been published in several journals, including the IEEE

This paper describes a design methodology for the confguration lmel of design; that is, the point in the design process where the amibutes of the design, not their values, are assigned. This methodology is based on an iterative redesign model previously shown effective at the paramenic lmel of design. In this paper the iterative redesign model is extended for confguration design, and tested in a computer program for the automated design of sheet metal brackets for simple structural joints. Several examples of the program are given and discussed.

“…This technique may be classified as a member of a general class of decompositional (abstract refinement (Mostow, 1984)) approaches to configuration. Other techniques within the same class of approaches have been utilized in (Brown and Chandrasekaran, 1985), (Maher and Fenves, 1985), (Mittal and Araya, 1986), (Mitchell et al, 1985), (Preiss, 1980), (Steinberg, 1987). This configuration methodology is intended for a weakly-connected, "nearly decomposable" (Simon, 1969) configuration artifact.…”

Configuration is a process of generating a definitive description of a product that satisfies a set of specified requirements and known constraints. Knowledge-based technology is an important factor in automation of configuration tasks found in mechanical design. In this paper, we describe a configuration technique that is well suited for configuring “decomposable” artifacts with reasonably well defined structure and constraints. This technique may be classified as a member of a general class of decompositional approaches to configuration. The domain knowledge is structured as a general model of the artifact, an and-or hierarchy of the artifact’s elements, features, and characteristics. The model includes constraints and local specialists which are attached to the elements of the and-or tree. Given the specific configuration requirements, the problem solving engine searches for a solution, a subtree, that satisfies the requirements and the applicable constraints. We describe an application of this approach that performs configuration and design of an automotive component.
