Abstract

The aim of this study is to design the new personalised insole for industrial workers. Shoe insole is one of the main component of shoes which is design to protect the underside or base of foot from pain. The insole provide comfort during walking or running and working activity. The problem statement of this project is to investigate back pain issues among the production line industrial workers. Standing posture are one of the factor to cause pain of the feet and has possibility to get back pain. There are some solution to overcome the pain that is to create a custom insole but the cost are quite high. This study is suggesting solution to counter the problem which is to design and develop new personalised insole using Additive Manufacturing (AM). AM is the process of joining materials to create an objects from the 3D CAD model layer upon layer. The development of the new design proposal is begin with understanding the level of pain based on area of foot and pressure distribution to carry out the section that contribute the highest pain area. Besides, the anthropometry of the foot is studied specifically according to the respondent in order to determine the suitable measurement for shoe insole. Later, a new design is proposed based on the data collection. The new design was analysed using FEA to find out the pressure. The new design personalised insole is fabricated and validate by using pressure distribution and Electromyogram (EMG). The result shows that by using a new personalised insole, the pressure distribution decrease, but unfortunately the result of EMG increase when using new personalised insole.
