In this work, we investigate the potential of using the solution space as constraint in an optimization problem of newly developed components: we propose a workflow to find the best compromise between the mass of a component and its crashworthiness. We provide a link between the solution space methodology - a systems engineering method for crashworthiness - and the shell thicknesses of newly developed components to better exploit the potential of the method itself. To do so, we use the Efficient Global Optimization (EGO) algorithms, constrained by the output of the solution space method - force intervals. By optimizing all components involved in a frontal impact we understand the limitations of the proposed workflow: despite the solution space method providing a guideline to develop all components independently, this is not always possible. We show to what extent one can use the solution space as a constraint in an optimization problem, hence, quickly finding the best compromise between independent development, mass reduction and crashworthiness.
