Abstract
In this paper, authors discuss how we can design method to support shoveling, and furthermore, how we should design way to support heavy load work done by human. To do so, we first focused on cycling, as shoveling and cycling both requires gross movement and heavy load work. From the perspective that we gain from the investigation, we designed and built two support-equipments for shoveling based on distributed motion type, which supports shoveling by utilizing another part of body, and based on motor assist type, which support shoveling by embedding actuator in the device. Finally, we proposed design approach from 5 perspectives to support high-load work. 1) using motor to reduce work load, in other word, mechanizing tool, 2) tool-izing machine by removing motor and substituting work done by motor to manpower, 3) specializing machines or tools into specific use to improve efficiency, 4) miniaturizing tool so that it is easy to carry or to use, 5) improving functionality of tool, for example increasing mechanical efficiency of power transmission, by use of machine element.
