Screwdriver
This ratchet screwdriver was developed for a study of anthropometrics in Industrial Design Studio. This particular design presents a comfortable yet powerful grip.
Existing ratchet screwdrivers are simply normal cylindrical screwdrivers, with a ratchet mechanism built-in. The obvious advantage however of a ratchet screwdriver is that the user’s hand does not have to move around the handle. This design concept proposes 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.
