Abstract:
Technical product development requires balancing diverse, often conflicting requirements through highly integrated and iterative design processes. The Design for X concept addresses multiple design aspects systematically, with tolerances crucially affecting product quality and lifecycle performance. However, tolerancing usually only considers aspects of functionality and manufacturabilty, neglecting further Design for X viewpoints, like lifecycle costs. In order to overcome the current hurdles in integrating these different viewpoints, this paper proposes a model-based approach leveraging Model-Based Systems Engineering and Product Lifecycle Management for tolerancing. By integrating simulations, design aspects, and requirements into a unified model, the approach enables targeted, traceable tolerance optimization. A drone development case study illustrates the approach’s practical application.
