Abstract

There are three main objectives in producing the thrower mechanism of the tennis ball machine. The first objective is to design a prototype of thrower mechanism for tennis ball machine. While for the second objective is to fabricate a prototype of thrower mechanism for tennis ball machine. Last but not least is to reduce the production cost of this machinery by using low cost materials. For this project, there are three different concept designs generated. Each design has its own characteristics. One of them needs to be chosen to pursue this project. So Pugh Concept Selection Method is used to select the best concept design for this project. Then concept design which used rotating wheels is selected as the best concept design. The fabrication of this tennis ball machine is using materials which are easily available in markets. The materials selection is based on the lower price because one of the project’s objectives is to reduce the production cost. Furthermore, local and recycles products are used as the machine’s components. This project not only focuses on the thrower mechanism, but generally the whole tennis ball machine is constructed. So when the construction finished, this machine can benefit many people especially Malaysian tennis players.
