In this article, we present a working knowledge model (WKM) that collates information from commonly used visual tools to support iterations in conceptual design of mechanical artifacts. The key aspects of the WKM are the notion of mappings and the ability to handle multiple descriptions and alternatives that are encountered during the design process. We show how common visual-models and tools such as House of Quality, function-structure, requirement and parametric diagrams can be described using the elements of the WKM. This connection serves as the basis for development of computational system for (1) acquiring, (2) displaying, and (3) manipulating the working knowledge with minimal disruption to the designer. A case study of the design of a mechanical neck for a humanoid robot is presented. This work demonstrates the ability of the model to accommodate information associated with these tools.
