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. A need exists for a device to aid them in standing up alone.
Objective: The device should be simple to operate, affordable, and covered by health insurance.

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

5. Current Design

6. Design Background and Possible Features
Ballscrew or Chain/pulley system for lifting
Stable welded steel frame for strength
Movable armrests for easy seat access
Tilting seat movement to aid the user in exiting the lift.
Simple easy access seat
Sufficient handlebars and supports to enter the seat

7. Possible Solutions Ball Screw Mechanism Linear Motion Guide
Using Ball screw

8. Model Pictures

9. Timeframe February March April
Begin modeling the device using demonstrative tools. Assess any design concerns or ideas for improvement. Apply concepts learned from our senior design course to our project such as design for failure, safety issues, biomaterials selection, FDA concerns, etc.
March
Finalize design and test the design to find weakness or flaws in the design in order to refine and improve the device. Minimize or eliminate any errors in our design. Begin preparing our final design for presentation.
April
Complete work on final presentation & prototype. Consider improvements. Gather information about the feasibility and liability of our design.
