DESIGN OF AUTOMATIC VIBRATING CHAIR WITH ECCENTRIC-AND-PITMAN FOR PROLONGED SEDENTARY ACTIVITIES

Sedentary behavior has become one of main inducted cause of physical decline. The pressure of modern life has further increased more working or studying time at home or office, contributing to the growing population of sedentary people furthermore. Prolonged sitting will affect people’s physical health, injuring our muscles, and causing physical discomfort. Seriously, it will lead to death. The purpose of this paper is to design a small convenient automatic vibrative chair for sedentary groups, which are driven by eccentric-and-pitman drive system, producing vibration and body movement to relieve physical problems. Double diamond design thinking method was used to find out the health problems including sedentariness and isolation. As a solution, design of the vibrative automatic chair was set as the theme of this study. The automatic vibrative chair was designed with biomimetic method, combining with industrial design principles and mechanical theories throughout structural design. The vibrating performance of the chair was verified using simulation method by adopting SolidWorks software.
