Abstract

Concept generation plays a critical role in product design especially in the early design phase when functional requirements are either uncertain or partially known. To cope with the uncertainty imposed by the varying work environment, resilient design has often been called upon to leverage system capacity from the perspective of functional requirements. While the resilient design has been advanced recently, how to design a resilient product structure so to accommodate more functional requirements at the conceptual design phase remains challenging. To tackle this issue, we propose a methodology to support resilient conceptual design using functional decomposition and conflict resolution. To reduce the impact imposed by potential issues and uncertain environments, the overall system functional requirements are defined based on five principles of resilient design. The redundant conceptual scheme that meets functional requirements is given resilience through functional decomposition and conflict resolution. A case study of the conceptual design of a hard rock coring structure present to demonstrate the feasibility of the proposed approach. The results yielded have suggested that the proposed approach can not only support resilient conceptual design, but also leverage design reliability and robustness under uncertainty, especially in terms of varying work environments.
