Design analysis of suitcase stabilizer and zipper protector

Abstract

Abstract In recent years we have seen a major shift and trend to the use of four-wheeled suitcase with the reason of easiness to manage and perhaps a better balance. Unlike four-wheeled suitcase with single storage platform with the edge opening models which provide rolling stability and comfort handling, four-wheeled suitcase with splitting storage platforms with the middle opening models is often given rolling instability and less comfort handling because the underside sometimes is uneven position and affects the movement of the wheels. Pushing beside and pulling behind a suitcase with rolling wheels instability over a long period of time can induce musculoskeletal disorders. Through the analysis of existing suitcase designs, the questionnaire was used to collect customer voice data from a random sample of 126 respondents. After that, a research was conducted to design products and simulate tensile strengths for several types of materials. Here, silicone is the best option for material of the product.
