|Abstract:||The study aimed to design a hand cart for the cart puller in the old Delhi area. We used a Generic Product Development Process as a base to design and test our new cart design for the cart pullers. The process had been used in a sequential procedure to get the best design solution. It also saves time and money which would be wasted in the reiteration of the cart design. It starts with User Research where we find out the basic user needs, which can be conducted via interview. Then to convert the user needs into applicable design specifications, we used a Quality Function Deployment (QFD). The next stage was to design the concepts, to do so we used the Morphological chart which helped us to generate concepts logically. After the generation of concepts, we had to select one concept which is the most promising one, to do so we used Pugh’s Concept Selection method and we landed on one concept. To make the detailed design of the cart we used dimensions from the existing cart and used Indian anthropometric data to add ergonomics into the cart design. A 3D CAD Design was made using detailed dimensions. Finally, based on CAD design a low fidelity prototype was made, and then it was translated into a 1:1 scale prototype. The last stage of testing was done and results were compared with the existing cart design in terms of Rapid Entire Body Assessment (REBA), Hierarchical Task Analysis (HTA) and Verbal interview.|
