Final Design

The Can Opener

The Can Opener was formed by combining all our sketches. It contains a wedge and a hook to lift and pull can tabs, respectively.

The handle was designed in for people who cannot use their thumb - due to either pain, immobilization, or amputation. Therefore, it goes in between the users hand palm and his/her index, middle, ring, and pinky fingers. The handle's curved features allow for maximum user comfort, and the pillar goes in between the middle and ring finger.

Its anatomy gives its user great leverage advantage to open cans with little applied force. Thus, it is also useful for users who can utilize their thumbs.

Dimensions were chosen based on regular can and hand sizes. The Can Opener is comfortable for most users and can be used to open most pull tab cans (including soda and food cans). Detailed dimensions can be found below.

To the left, technical drawings of the Can Opener can be found.

It is a relatively simple part, with the hook being its most complex feature.

Dimensions' units are centimeters.
