  1. Stand Alone Group Members: Jaime Alvarez Austin Chamberlain Trey Smith Jung Hoon Kim

  2. Executive Summary • Problem: Elderly or disabled individuals living alone may fall and need help getting to their feet. A need exists for a device to aid them in standing up alone. • Objective: Design and build a device to help people stand from the floor. The device should be simple to operate, safe, and affordable.

  3. Approach • Conduct thorough Biomechanical analysis to yield the best solution: • Conduct research on nature and severity of falls • Consult physical therapist for further information on falls • Analyze feasibility of device for various conditions • Use BME, ME, and EE expertise to design the best solution

  4. The Market and Similar Devices • 1991 NASA study estimated 8 million people could benefit • Many types of lifting devices exist • Problems with existing devices • User has to possess good upper/lower body strength • Don’t lift high enough, descend low enough • Designed for wheelchair transport

  5. Solution: Stand Alone Device • Fixed and stable • Easily Accessible • Unobstructed entrance • Simple Mechanism

  6. Design Background and Specifications • Chain/pulley system for lifting • Protection from moving parts • Stable, welded iron frame for strength • Seat should come down to less than 1 in. from the ground • Seat should lift high enough for all people (at least 3 ft) • Tilting seat movement to aid the user in exiting the lift. • Simple control and easy-access seat • Seatbelt for safety • Cut-off switch • Reduce friction and noise
