Keynote presentations
Optimization is Not Innovation
Peter F. Pelz
Darmstadt University of Technology - Department of Mechanical Engineering - Chair of Fluid Systems
For decades, organizations have perfected the art of optimization. Products become faster, processes become leaner, and algorithms become more efficient. Yet history shows that the greatest technological breakthroughs rarely emerge from optimization alone. This lecture argues that optimization and innovation are fundamentally different processes. Optimization improves existing components within a known design space. Innovation creates an entirely new design space by changing the underlying system. Drawing on examples from biology and engineering - from the evolution of blood circulation to Hermann Fottinger's invention of the hydrodynamic torque converter - the talk identifies a universal pattern that governs transformative innovation. The same principles apply not only to natural evolution and engineering, but also to technology organizations. The message for technology leaders is both simple and challenging: organizations that excel at optimization are not necessarily prepared for innovation. Sustainable technological leadership requires knowing when to optimize an existing architecture - and when to abandon it in favor of a fundamentally new one.
Peter F. Pelz is Full Professor of Mechanical Engineering and Head of the Chair of Fluid Systems at Darmstadt University of Technology. He studied mechanical engineering at TU Darmstadt and mathematics at Trinity College Dublin and received his doctoral degree in mechanical engineering from TU Darmstadt in 2000. Following several years in industrial research and development at Freudenberg and Vibracoustic, where he held leadership positions in fluid mechanics, rheology, and advanced development, he was appointed Full Professor at TU Darmstadt in 2006.
Peter Pelz’s research covers a broad range of topics in fluid systems engineering, including turbomachinery, cavitation, tribology, rotordynamics, fluid power systems, and the design and optimization of sustainable and resilient fluid systems. His work combines fundamental fluid mechanics with experimental investigations, mathematical modeling, and systems engineering. From 2013 to 2021, he served as spokesperson of the DFG Collaborative Research Centre 805 “Control of Uncertainty in Load-Carrying Systems in Mechanical Engineering.” Since 2021, he has been founding spokesperson of the research field Energy & Environment at TU Darmstadt, and since 2022, he has been founder and Editor-in-Chief of the diamond open-access journal ing.grid – FAIR Data Management in Engineering Sciences. Since 2025, he has served as spokesperson of NFDI4ING, the German National Research Data Infrastructure for Engineering Sciences. He is also Vice President of TU Darmstadt for Digitalisation, Sustainability and Infrastructure.
