Use of Technologically and Topologically Related Surfaces (TTRS) geometrical theory for Mechatronic Ontology

Today, very few research studies have focused on the integration and importance of geometrical knowledge consistency management in the conceptual design for the selection of promising solution concepts related to their 3D component positioning and physical behavioral constraints. As the geometrical data can be multiple and varied, they actually depend on the model they are used in. When considering the mechatronic systems design, geometry challenges mainly relate to their high physical integration, be it to increase their compactness (that needs to be evaluated through metrics), or to take into account multi-physical couplings due to the proximity of components. The definition of a suitable ontology including the geometrical point of view is then required in order to ensure the geometrical data consistency in such a complex mechatronic system design thanks to a Model-Based System Engineering (MBSE) approach. Indeed, semantic knowledge-based engineering can efficiently support an automatic consistent products design.
