4 Elements was hired by Bissell to develop a transmission and power drive for their upright deep cleaning machine. Since the original tools existed for the original product, it was our job to incorporate the new power drive feature with minimal tool revisions to existing tools. We came up with a concept that enabled us to incorporate an electric motor and transmission into the existing housing with minimal changes. Our concept utilized a belt drive which we were able to hide with a small side cover from the wheel to the transmission. 4E prototyped and tested prior to the release of engineering databases for tooling.
