Dwell linkages have numerous applications in industry,especially in automation. Traditional use of more expensivecams is due to lack of proper design tools for synthesizingdwell linkages. By systematically and extensively studyingentire motion characteristics of hundreds of linkages, acomprehensive classification system and heuristics weredeveloped. This qualitative classification scheme led to afinite set of linkage models that cover the entire designspace in the sense that any possible design falls under oneor more of the models. Our system, called Dwell-Expert,incorporates design expertise to select the best linkagemodel for a given set of design specifications and to compare that model against alternatives. This new designmethodology and its implementation in AGNESS (A Generalized Network-based Expert System Shell) are explained.A design example is presented. Our system can reduce evenan experienced designer's initial-design time from a day ormore to a minute or less, assuming specifications havealready been formulated. Such results motivate extensionof this design methodology to other areas of mechanicaldesign and engineering design in general.
