A study of a Smart Folding Chair for Welding Workshops in the Mechanical Engineering Department

Abstract

The Smart Folding Chair is an innovative upgrade of the original Classroom Folding Chair, which was designed to address space limitations in welding workshops. The initial version introduced a foldable frame with wheels for improved space management in confined areas. However, it relied on a manual folding mechanism, which posed challenges in usability and convenience during frequent use. Additionally, the absence of smart features limits its relevance in modern learning environments. The main objectives of this project are to develop an automatic folding chair that can be controlled using a mobile phone, to optimize the physical effort and energy required for arranging and storing chairs in confined learning environments, and to build an electronic circuit system that automates the folding process using an Arduino microcontroller. These objectives aim to improve functionality, enhance user convenience, and support the implementation of smart technology in technical and vocational education settings. The methodology involved integrating an Arduino UNO with a Bluetooth module (HC-05) and motor system into the chair’s frame. The system was programmed to respond to mobile commands for folding operation. The results showed that the upgraded chair successfully performed automated folding within seconds, improving efficiency, user convenience, and overall functionality. This version is more adaptable for use in technical workshops, classrooms, and multipurpose educational spaces. In conclusion, the Smart Folding Chair offers a practical, modern solution that supports Industry 4.0 by introducing automation into traditional furniture. As a recommendation, future developments should focus on improving battery efficiency, enhancing system durability, and exploring features such as solar charging and motion sensors to further increase functionality and sustainability.
