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.
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
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
Solution: Stand Alone Device • Fixed and stable • Easily Accessible • Unobstructed entrance • Simple Mechanism
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
Timeframe • March • Assess areas that need improvement. • Reduce noise of motor. • Safety issues. • Begin preparing our final design for presentation. • Begin analyzing body stresses. • Add comfortable, user-friendly features to the device . • April • Estimate the cost and possible price of the device. • Complete work on final presentation & prototype. • Complete comfort and safety improvements.
Costs • Winch: $150-$200 • Angle iron: $0.60/foot • Welding materials: $10 • Resources • BME lab workshop • Machine Shop
Team Qualifications • Jaime Alvarez – ME, Experience with Robotics and Formula SAE participant • Austin Chamberlain – BME • Trey Smith – BME • Jung Hoon Kim - BME, EE , Electrical Engineering expertise for possible use in device control system and operation
Advisers & Consultants • Dr. Paul H. King- Professor of Biomedical Engineering • Jason Roberts- State of Tennessee's Employment Security • Professor Barnett – ME Professor • David Owens – Owen Business School Professor • Gary Chamberlain - Welder/ Carpenter
