A goal-oriented, inverse decision-based design method to find satisficing solutions for multiple football helmet components that all work together to achieve a set of conflicting goals is presented. The efficacy of the method is illustrated with the design of the top region of an American football helmet. The prototype helmet was first constructed and tested with a twin-wire drop tower to study the different components effect on the system response. The inverse design method is used to design the foam liner to dissipate the maximum impact energy, and then the composite shell is designed to reduce the weight. The Concept Exploration Framework and the compromise Decision Support Problem are used to find satisficing solutions to the system-level performance goals under uncertainty. The proposed goal-oriented, inverse decision-based design method is generic and will be used to design additional components, the complete helmet, and ultimately helmets for other sports.
