Application to Artificial Hip Stem Design of an Emergent Design System Applicable in the Early Process of Design

In the early process of design called conceptual design and basic design, diverse design ideas must be obtained from global solution search under the constraint of unclear design conditions. It is difficult to derive an adequatede sign solution to a design object with complicated conception because the current method of deriving current diverse solutions depend solely on designer´s experience and knowledge. Therefore, it is thought that, with a method of deriving diverse solutions globally, it leads to the further improvement of design environment. From these backgrounds, an emergent design system that derives diverse solution is proposed. Then, to construct the emergent design system, this system was applied to the artificial hip stem design. Moreover, the effectiveness of diverse solutions derivation in this system was indicated by comparing the solutions derived from this system with the solution that executed the conventional optimization method, and it contributed to construction of this system.
