Patented Battery-Operated Can Opener
Engineering of mechanical setup of this item had several challenges. First and foremost was to keep cost down while using two electric motors, each driving its own gearbox. Both motors had to produce considerable forces and at the same time not drain rechargeable battery too fast. One motor had to drive can rotation, overcoming resistance of stationery cutting blade. Second motor had to push press plunger with at least 12 pounds of force. And both functions had to be done with a reasonable speed – not too fast and not too slow.
Packing motors, batteries, gears and PCB chips into a handheld device is always a challenge, since device itself has to work pretty much in a human hand of any type: small, large, man’s or woman’s, left and right. Then comes designing and positioning of buttons and latches in such a way that users can hold item in their hand and comfortably and intuitively operate its components.
