Abstract

This project titled as “Design and Fabrication of Motorised Suitcase. The motorised suitcase is a combination of a motorized scooter and a suitcase. It can be transformed into an ordinary suitcase with a pulling handle. Carrying heavy luggage bags are always traveller problems. The larger and heavier the luggage, the more at risk for neck, back and shoulder injuries. Lifting and carrying bulky luggage can strain a person’s bones, muscles and joints. Furthermore, travellers waste too much time on dragging around their luggage in the airport. Normally, once they landed, they are all rushing to leave the airport and get to their destination as fast as possible. Besides that, many luggage damage happen due to airline mishandling. When the airline worker transfer luggage up to plane or unload them from the plane, the luggage probably will get squashed into the plane storage. Hence, the aim of this project is to design a motorized suitcase which able to solve the existing problem face by the travellers. Moreover, this project is also aim to develop an economical and affordable motorized suitcase for public that can travel smoothly on streets and airports. After the existing motorized suitcases are studied, the objectives and design requirements of this project are determined. The objectives of this project are to design a suitcase which can travel at a speed up to 25km/h and the mass of the suitcase without load is less than 10kg. Besides that, the suitcase is designed to support user weight up to 100kg and is able to absorb falling impact without damaging itself and the belongings. The size of the resulting prototype is 0.65m x 0.25m x 0.38m. The size is set based on the average size of ordinary suitcases and the space available to fit 5 to 6 foot tall adults comfortably. The prototype enables user to transform it into dragging mode. Basically, it consists of a scooter, aluminium structure, polycarbonate sheets and driving mechanism. The scooter is responsible to drive the whole structure controlled by the rider. The aluminium structure is responsible to support rider’s weight and to accommodate user belongings. The polycarbonate sheets are used as the cover for the suitcase which enable it to absorb incoming impact to itself. The prototype has undergone some testing. The tested speed of the prototype is 23.3km/h where the target speed is 25km/h. The measured weight of the suitcase without load is 15.5kg higher than the target weight. An 85kg and 6 foot tall man had tested the prototype and it worked without any deformation. The polycarbonate sheets have provided the suitcase the feature of impact resistant. According to the feedback from a group of testers, the overall feelings of riding the suitcase was fun and stable. In short, the innovation in this project is to produce an economical, viable and affordable motorised suitcase for public which can carry load and travel smoothly on streets.
