Presentation Title: From Shapes to Systems: Rethinking Design with Topology Optimization
Abstract: Despite over three decades of research, topology optimization (TO) continues to provoke a mixed reception in the engineering design community. Lauded as a natural companion to additive manufacturing (AM), it is simultaneously criticized as impractical for real-world engineering design. What remains clear is this: TO is not a push-button tool that produces perfect, ready-to-manufacture designs on demand — nor was it ever meant to be.
Yet, in an era of generative AI and conversational design interfaces, where "optimal" solutions are increasingly promised with little more than a prompt, the expectations surrounding automated design tools are shifting. Against this backdrop, TO holds a distinct, and perhaps underappreciated, value: the ability to deliver creative, unintuitive solutions in domains where traditional design intuition fails.
This presentation explores the recent advances of topology optimization — not as a universal tool, but as an essential enabler for complex, multiphysics, and multifunctional systems. In simple, single-function applications, optimized results often align with engineering intuition, reducing the marginal value of TO. However, as modern design problems grow in complexity — requiring interdisciplinary integration and multiphysics/multiscale coupling— human intuition alone is no longer sufficient. Upon reflection of the current research direction in the context of an ever growing class of complex engineering system, the presentation will highlight its capabilities and the substantial challenges that remain.
