Development of a geometric model retrieval system: a design exemplar case study

Abstract

This paper presents a case study examining design exemplar technology implemented as a search and retrieval tool fortire mould inserts. Limitations of using the geometric-based exemplar approach, such as tediousness of authoring exemplars and time complexity, are identified and addressed through a new parametric-based exemplar approach. Here, the maxima and minima are calculated based upon the specifications of the query mould insert. The design exemplar is demonstrated to be useful primarily in prototyping query mechanisms. Ultimately, customer requirements necessitated implementing the parametric approach as a dedicated software package grounded on the exemplar based prototyped query mechanism.

Beyond assembly features: systematic review of the core concepts and perspectives towards a unified approach to assembly information representation

“…The exemplar can represent geometric, topologic, semantic, and algebraic relationships in a data structure with orthogonal components (a bipartite graph); it was originally used for design problems representation and support pattern matching, property extraction, design validation, and model modification (Summers et al 2004). A case study was developed to show its querying capabilities; however, it was concluded that further work is needed to leverage the workload in creating the exemplars (Srirangam et al 2014). Since the exemplar data structure can store several types of information, we included it in this literature research as an approach that could be applied to assembly in the future.…”
