A common torchlight comprises of a lighting source fixed in a reflector and a clear lens, battery, switch and enclosed or protected body case. Based on the original design of this torchlight, customers are having problem to hold the torchlight due to poor grip and causing the torchlight easy to slip off and possibly get damaged when it falls into the water. The objectives of this project intend to improve the torchlight design to secure handling, maintenance, and to increase the durability of the torchlight against water using Àoat material which also enables the user to locate the torchlight in a short time. In conclusion, this study also identifies the possible environmental factors that assessed using sustainability tools to ensure the entire design structure will enhance the sustainability issue. Thus, based on the sustainability assessment, the float material able to apply for this purpose to achieve the objective, and the design concept is according to the customer requirement.
