This is a pill bottle opener that I designed, manufactured, and assembled. I made it for injured veterans with disabilities such as hemiplegia, amputations, and other motor disabilities that can hinder their ability to open and close medication containers. This design alleviates this problem by featuring a pair of buttons and levers that require minimal strength and no fingers to operate. It also accommodates a wide range of pill bottle sizes.

To use it, a pill bottle is placed on the red platform, which is covered with a layer of silicone, providing enough grip to hold the bottles still without damaging them. Then, the 'plunger' is lowered by the user to compress the bottle's lid to disengage the locking mechanism. The lever at the back rotates the pill bottle to open it. Finally, the blue lever at the top resets the plunger's position to enable the user to retrieve the pill bottle. To close a bottle, the user only needs to follow the same steps in reverse.

The smooth design of this device prevents any injuries to the user during operation, and its weight of 3 lbs makes it highly portable. Additionally, it requires no batteries and can be carried with one arm and no fingers. Its driving mechanisms include compression and extension springs, a ratcheting gear and pawl, a gear and rack system, and a gear train housed within the base.

I performed Finite Element Analysis on the structural components to ensure that the device can withstand greater loads than it will experience during regular use.
