碩士 === 國立臺北科技大學 === 製造科技研究所 === 94 === The adjustable chairs according to the height and size, the user can adjust the position to make them comfortable and to improve working efficiency. The purpose of this research is to develop an adjustable chair. This research collected all literatures about adjustable chairs. The collected literatures including papers and patents were analyzed and classified according to their functional purpose, position of adjustable mechanisms, and time of publication. Adjustable chairs can be classified into four types, namely, basic type, advanced type, luxurious type, and particular-purpose type. Based on the customer requirements, we also use quality function deployment for adjustable chairs. And each position of adjustable mechanisms was finally chosen for concept development by using the analytic hierarchy Process. Then, computer aided design technique was used to design the parts. In addition, stress analysis of the parts for ensuring the quality of the design. The adjustable office chair designed is fitted for the people 140 to 190 cm height, the chair also has the adjustable seat for forward, backward 4 cm, and upward 14 cm adjustment , and also the mechanisms for backrest inclining adjustment up to 30 degrees.
