A Step Toward Risk Mitigation During Conceptual Product Design: Component Selection for Risk Reduction

  • Daniel Krus

Technical Article---Peer-Reviewed


The objective of this article is to introduce a method that will mitigate product risks during the conceptual design phase by identifying design variables that affect product failures. By using this comprehensive, step-by-step process that combines existing techniques in a new way, designers can begin with a simple functional model and emerge from the conceptual design phase with specific components selected with many risks already mitigated. The risk in early design (RED) method plays a significant role in identifying failure modes by functions, and these modes are then analyzed through modeling equations or lifespan analyses, in such a manner that emphasizes variables under the designers’ control. With the valuable insight this method provides, informed decisions can be made early in the process, thereby eliminating costly changes later on.
