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.

使用通用产品开发流程设计和制造的针对旧德里整个销售市场的新型手推车

该研究的目的是为旧德里地区的拉车设计一种手推车。我们以通用产品开发流程为基础来设计和测试用于推车拉手的新推车设计。该过程已按顺序使用，以获得最佳设计解决方案。这也节省了时间和金钱，这在重复购物车设计时会被浪费。首先从用户研究开始，在这里我们可以找到基本的用户需求，可以通过访谈进行。然后，为了将用户需求转换为适用的设计规范，我们使用了质量功能部署（QFD）。下一步是设计概念，为此我们使用形态图来帮助我们逻辑地生成概念。在产生概念之后，我们必须选择一个最有前途的概念，为此，我们使用了Pugh的“概念选择”方法，并着手了一个概念。为了进行详细的购物车设计，我们使用了现有购物车的尺寸，并使用了印度人体测量学数据来将人体工程学添加到购物车设计中。使用详细尺寸进行了3D CAD设计。最后，基于CAD设计，制作了低保真度原型，然后将其转换为1：1比例的原型。测试的最后阶段已经完成，并且在快速整体身体评估（REBA），分层任务分析（HTA）和口头访谈方面将结果与现有推车设计进行了比较。最后，基于CAD设计，制作了低保真度原型，然后将其转换为1：1比例的原型。测试的最后阶段已经完成，并且在快速整体身体评估（REBA），分层任务分析（HTA）和口头访谈方面将结果与现有推车设计进行了比较。最后，基于CAD设计，制作了低保真度原型，然后将其转换为1：1比例的原型。测试的最后阶段已经完成，并且在快速整体身体评估（REBA），分层任务分析（HTA）和口头访谈方面将结果与现有推车设计进行了比较。
