Product design of chairless chair based on local components to provide support for active workers

Abstract

One problem faced by active workers is limited seating facilities especially in public transportation where they have to stand as they are carrying out their activities for long periods of time. In industry, the limited work area makes it impossible for operators to use seats, so operators have to stand for long periods when operating the machine. This study aims to design a chairless chair by utilizing local components that are cheap and easy to obtain in the market. The chairless chair product design uses the VDI 2221 method, while analysis of the strength of the chairless chair structure uses Autodesk Inventor 2017 software. In this design, several design variants have been made which are then compared by assessing their volume, mass, production costs and comfort levels, so that the best design variants for prototyping are obtained. Based on the results of the research, a comfortable, safe to use chairless chair was produced with local components. The results of this study become a reference for further development.
