Self Raising Mobility Jack

Started Apr. 19, 2023

Abstract or project description

This research focuses on enhancing the traditional single wheel jack and building a semi-automatic short-distance mobility solution for immobilized cars. The primary objective is to enable swift relocation of vehicles in emergency situations, eliminating the need to start the engine and, in the case of hybrid drive-train or electric cars, avoid the necessity of towing. The proposed innovation allows for easier car positioning and movement. This holds significant potential value not only for individual users but also to businesses, particularly those engaged in vehicle maintenance and recovery services, who will be able to use the improved convenience to enhance their efficiency in attending to immobilized vehicles or maneuver cars in highly space constrained places such as small-sized workshops. The technical foundation of this research is to understand the various car jack technologies in existence, bring in other related mechanical engineering and power conversion systems such as hydraulics and wheeled platforms, and integrate them into the concept product. The non-technical aspects considered focus on general utility, affordable costs of manufacture, and ownership and portability. Car jacks currently utilize various technologies, such as simple machines’ mechanical advantage, hydraulics, and pneumatics. This paper explores the potential of employing pneumatics, hydraulics and screw/scissor-jack mechanisms to create portable, motorized jacks equipped with wheels that can be easily attached to any car's jacking points. The proposed end product will use a motorized scissor lift mechanism powered using the car’s battery and will be mobile via omnidirectional wheels mounted on the bottom surface. There will be one jack per corner of the vehicle. To achieve this goal, advanced tools and methodologies, including Computer-Aided Design (CAD) in conjunction with a rigorous process of prototyping and experimentation will be employed. Through this comprehensive approach, the study presents a viable solution that enhances vehicle movement accessibility and efficiency during critical scenarios.
