The objective of this work is to design and build a device to reduce the incidence of inadvertent release and ACL injuries for skiers. Inadvertent release occurs when sufficient work is done on a binding to separate the boot and the binding. Inadvertent release often results in loss of control resulting in serious injuries and death. Axiomatic design was used to link functional and physical decompositions and avoid unwanted coupling. In particular, it was important to decouple pitch, roll, and yaw so the spring system only influences fore and aft pitch and vertical displacement. Both roll and yaw loads are transferred through an interlocking "half moon" coupling mechanism. The approach is to increase the "work to release" without impairing the transfer of control loads from binding to ski.
