This project aims to design and build an ergonomic bag to help improve posture in adolescents and prevent back problems later in life. The bag will be designed to suit body position and not cause damage from the weight carried. It will incorporate knowledge from different areas and use new technological innovations like wider shoulder straps. The expected results are a bag that promotes good posture, prevents illness or back pain, and can be positioned in the market. It will involve research, design, construction, and exhibition of the bag over approximately one year.
