  • Abstract In the e-generation, electricity is required to start all electrical appliances and peripheral equipments. Various plugs are produced for connection with the corresponding socket outlets to transmit the required power. At present the face plates of stationary socket outlets are all parallel to the wall and do not allow adjustment in response to the motion of the hand. Not operating from the neutral position, the wrist becomes prone to injuries. The purpose of this study is to design an appropriate plug angle in order to alleviate the ulnar deviation, radial deviation, palmar flexion and dorsal flexion generated as a result of the user’s plugging and unplugging actions.
    This study first classifies the types of plugs and tests different socket outlets. Users are asked to subjectively evaluate and compare plugging and unplugging difficulties. According to the results, the plugs are divided into 2 types: 90∘and 180∘.
    Through descriptive statistics, two-way ANOVA and LSD, experiment results show the impacts of the angles between 2 socket outlet positions and 10 different plugs on the wrist: 90∘plugs can easily cause dorsal flexion; 180∘plugs are liable to bring about ulnar-radial deviation. The ulnar deviations caused by socket outlet positions are most significant during the test, but no radial deviation is noted.
    In the final stage, an adjustable socket outlet jig is employed to test the wrist in 2 height positions and 14 angles in conjunction with plugging and unplugging of 90∘and 180∘plugs. The deviation of wrist is recorded. Two design proposals, one on middle-position socket outlets and one on lower-position socket outlets, are presented for practical application.
