Here is the concept for the mechanical design.
1. Places the device over the bottle cap, then clamp it by twisting the handle below. (the lower cylinders are hollow.
2. Press the top dome repeatedly. The gear will turn the clamp with every press.
3. To close the bottle, flip the switch at the top to the opposite direction, and repeat step 2. The gear will turn the clamp in the opposite direction.

....Character development for the bottle aid...
The "Palm + Gear = Bottle Opener" solution has developed into the Bottle Aid. The device clamps to the bottle and the cap. Pressed with the palm, the upper and lower clamp twist in a contra-rotating movement to open the cap. A spiral/helix thread produces a simultaneous turning and lifting motion. The function of the device is to loosen the bottle cap to an acceptable level where it can already be removed single-handedly.
