Abstract

This project focused on the design and fabrication of an automated scissor jack, developed as an improvement over a conventional manually operated model. The primary objective was to enhance usability by integrating a 12V DC motor, which enables a wider range of users, including women, pregnant individuals, and those with physical limitations to operate the jack with ease in emergency situations. The design aimed to promote gender equality and inclusivity while maintaining affordability and user-friendliness. The development process incorporated key engineering calculations to determine the required lifting force, torque, and motor specifications, which ensures the system to function effectively under typical vehicle loads. The final prototype demonstrated the ability to lift part of a vehicle with reduced physical effort, although some performance limitationswere observed under full-load conditions. Overall, the project successfully highlighted a cost-effective and accessible approach to improving traditional lifting tools, with potential for further refinement and real-world application.
