Senior Design Project P06201: Modified Home Entry Robert Karpowicz Brian Long Jeff Webb Josh Ribbeck

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

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.

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.

4 Concepts for Door Opening  Linear Actuator  Motor and Gear  Hydraulic System  Pulley system

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.

Linear Actuator Design Concept Sketch

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

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.

Hydraulic System – to Open Door

 Pros –Off Shelf Components –Simple Design  Cons –Noise –High power Consumption –Cost –High maintenance

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

Electromagnetic Unlocking

 Pros –Easy set up, and maintenance –Only 1 moving part. –Quiet –Cheap  Cons –Questionable effectiveness

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.

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.

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.
