Senior Design Project P06201: Modified Home Entry

1. Senior Design Project P06201: Modified Home Entry Robert Karpowicz Brian Long Jeff Webb Josh Ribbeck 2005-2006

2. Introduction • Client: Arc of Monroe County • Sponsor: National Science Foundations • Goal: To create a system to open and close main doors automatically for handicapped residents at two assisted living locations • Locations – 2 Arc of Monroe County Assisted Living Locations • 1969 Middle Road in Rush, NY • 1860 Fairport Nine Mile Road in Penfield, NY

3. Needs Assessment Objectives • Door needs to open and close on its own with only input from an operator. • Activation via a wireless remote. Only individuals with remotes can utilize the system. • System to operate only when not in use. • Preserve regular function of the door. • After opening, the door should remain open until closed or close on its own. • Door should detect an object in its path on either side. • Reliability and ease of maintenance.

4. Major Design Requirements • 1- Door speed should be 15 degrees/second. • 2 - While in motion the system should detect object within 36” in front or behind the door. • 3 - Door should remain open for 30 seconds before automatically closing. • 4 - Remote control should activate with a 2 lbf input. • 5 - Remote Control should operate within 10 ft. • 6 – Resistance of only 5 lbf during manual operation.

5. 4 Concepts for Door Opening • Linear Actuator • Motor and Gear • Hydraulic System • Pulley system

6. 2 Concepts for Lock Actuation • Electromagnetic Acutation • Rack and Pinion with a motor 1 Concepts for System Activation • Wireless remote control, with receiver to activate system.

7. Linear Actuator Design Concept Sketch

8. Linear Actuator – to Open Door • Pros • Complete Electronic Control. • Minimum resistance to Manual Operation. • Simple Integration. • Only 1 moving part low maintenance. • Minimal Changes to the house. • Cons • Long Travel • Cost

9. Motor and Gear System – to Open Door

10. Motor and Gear System – to Open Door • Pros • Off the Shelf Components • Easy integration • Low Cost • Quiet Operation • Low Maintenance • Cons • High resistance to Manual operation.

11. Hydraulic System – to Open Door

12. Hydraulic System – to Open Door • Pros • Off Shelf Components • Simple Design • Cons • Noise • High power Consumption • Cost • High maintenance

13. Pulley System – to Open Door

14. Pulley System – to Open Door • Pros • Cheap • No resistance to manual operation • Cons • Integration • Needlessly Complicated • Fragile operation • In the way of manual Operation • Aesthetics

15. Electromagnetic Unlocking

16. Electromagnetic Unlocking • Pros • Easy set up, and maintenance • Only 1 moving part. • Quiet • Cheap • Cons • Questionable effectiveness

17. Rack and Pinion with Motor Unlocking

18. Rack and Pinion with Motor Unlocking • Pros • Reliability • Off the shelf components • Cons • More moving parts to create maintenance issues. • Bulky assembly in an already tight area.

19. Information about Actuation and Unlocking Systems • Standard Stamp to be used for programming. • Remote control and receiver will be similar to garage door style receivers. • Pros • Easy to use, allows only certain people to use the system. • Cons • Cost and adjustability of programming.

21. Summary • This project provides the unique opportunity to improve the quality of life of the inhabitants of the Arc of Monroe Counties Assisted Living Locations.
