Screwdriver
This ratchet screwdriver was developed for a study of anthropometrics in Industrial Design Sophomore Studio. This particular design delivers a comfortable yet powerful handle grip.
Existing ratchet screwdrivers are simply normal cylindrical screwdrivers, with a built-in ratchet mechanism. However, the obvious advantage of a ratchet screwdriver is that the user’s hand does not have to move once gripping the handle. This design concept delivers a more comfortable and ergonomic handle for the user to grip.
A prototype ratchet mechanism was built into the handle to simulate the ratcheting motion.
The design process.
