Gear ratio can openers
Some hand can openers require notable effort to operate; thinking seniors a near effortless version could simply have an extra gear and a gear ratio 2:1 so that half the effort was needed to open a can. | |
It is possible that people in the developing world do not have electric can openers. Putting an extra gear on a hand can opener with a gear ratio of 2:1 would make opening cans almost effortless which could also be good for seniors.

The next logical step is to have multiple gear ratios for different types of can, and some kind of automatic transmission to switch between them. [+] |

Really? - I would
have thought some sort of CVT mechanism would be
preferred |

Sounds good but might have to do some focus groups to see if people like the round twice can opener. |

If it incorporated a tiny arc-welder it could be a
can-closer as well as a can-opener |

The extrapolation of this means even less effort to get needed calories. An intravenous drip from the farm to your arm. |

We also considered that this would be a perfect application for a minature epicyclic gearbox. |
