The present invention is directed to a system and method for parallel configurable IP design. Alternatively, the electrolyte can be a non-aqueous ionic conducting electrolyte or a solid electrolyte. The recessed engaging trough engages with a hook end of the restricting piece, so the restricting piece can tightly clamp a fixed edge of the elastic air bag. Each plurality of recesses is positioned such that a center of each recess is a point on a circle coaxial to the plate.
