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
