A further development of the research has revealed that the solutions obtained from several topological optimizations can be considered as elementary customized modeling features for a specific design task. The topology overcoming the arising geometrical contradiction can be obtained through a manipulation of the density distributions constituting the conflicting pair. Already two strategies of density combination have been identified as capable to solve geometrical contradictions.enCopyright: Cranfield University 2009Computer-Aided InnovationComputer-Aided Conceptual DesignEmbodiment DesignTRIZConference paper
