Many people use screwdrivers with too much force, which may result in blisters on hands. In order to solve this problem, Wang, Cyun-Kai from Department of Innovation Design Engineering of National Kaohsiung First University of Science and Technology modified the design of a screwdriver with the addition of a click button. When the user keeps clicking the button, the inner gear will push the screwdriver to turn, so the fastener can be tightened or loosened. He said that such a new screwdriver is user-friendly and can save 50% of the time of tightening a screw. In addition, this design offers the interchangeability for bits and makes it possible to turn screws clockwise or counter-clockwise. The grip is quite slim and is suitable for holding and clicking with only one hand.

This design has been awarded by a SPONSOR’S special prize in the ceremony of Taiwan Young Designers’ Award 2014 (YODA) http://www.yoda-tw.com/previous-works/all-previous-works/work/152.html
