  1. P16680: AATech Universal Oil and Bag System System Design Review 9/29/15

  2. Team P16680 Philip Couturier - Controls Systems (EE) Samantha Orlando - Systems Design (ME) Jessica Reed - Purchasing (ME) Maria King - Project Lead (ISE) Nicole Anklam - Systems Integration (EE) Bryce Mowers - Manufacturing (ME)

  3. System Design Review Objectives • Confirm that all system goals are addressed in an acceptable manner • Inform stakeholdersof current project status • Update engineering requirements if needed • Review action items for team & customer

  4. Agenda Engineering Analysis Test Plan Risk Assessment Project Plan Lessons Learned Q & A Action Item Recap • Use Scenario • Engineering Requirements • Constraints • Functional Decomposition • Systems Architecture • Benchmarking • Concept Generation & Selection • Cost

  5. Updated Use Scenario

  6. Engineering Requirements

  7. Constraints

  8. Functional Decomposition

  9. System Architecture

  10. Drain apparatus Height of table Door handles Oil lines Benchmarking • Pumps • Sensors • Barcode scanners • Microcontrollers

  11. Morphological Chart

  12. Concept Generation Three Potential Concepts • Manual Concept • Automated Concept • Feasible Automated Concept

  13. Concept Selection Selection Criteria: • Ease of use / Ease of troubleshooting • Ergonomic • Can be completed in two semesters • Durable • Fast cycle time • Size (small preferred) • Organized • Automated • Adaptable

  14. Concept Selection - : Less likely to meet criteria + : More likely to meet criteria s : Equally likely to meet criteria

  15. Final Concept Selection • Combination of best components from each system concept • Different fixture for each model • PLC/HMI display with LED lights • Manual Door Slide with electric door interlock • Locate and secure nozzle using a yoke plate (previous MSD team) • Manual input with a scanner • Electric Centrifugal pump to circulate oil • Internal reservoir to store oil • Gravity flow to return oil to reservoir

  16. Cost Budget: $10,000 • Estimated costs of major components based on benchmarking: • HMI/PLC - $800 • Sensors - $250 • Door Lock - $50 • Pump - $500 • Door handles - $10 • Oil lines - $80 Total: $1,690

  17. Engineering Analysis • How many fixtures are needed/What parts need to change? • Prototype different options • How long will a changeover take? • Prototype a fixture and time a mock changeover • Will the pump provide appropriate pressure and duration? • Benchmark • Which type of door lock ensure safety and eliminate leaking? • Benchmark • Will all of the sensors be compatible with the PLC? • Benchmark

  18. Test Plan • Pump--verify the pressure at different points • Pneumatics--verify cylinder actuation and verify no bleed-off • Pressure sensors--verify they meet specs • Fixturing alignment--verify part fit-up with oil injector • Cycle time--different parts and change-over • Door lock--verify that the door will not open during operation • Noise level--verify less than 50dB • Scanner--verify communication with PLC and pulls up correct parameters • LED and HMI--verify the systems output the correct data at the correct time • User interface--verify intuitive controls • System Control--verify system runs correct parameters and operates as planned

  19. Risk Assessment

  20. Project Plan Gantt Chart thru 9/29 Rest of Project Next 3 weeks

  21. Lessons Learned • Have a method to track risks at a high level • Project schedule may vary from MSD schedule • Have document owners • Practice design review with your guide

  22. Questions?

  23. Action Item Recap • From previous review • Receive oil requirements • Receive copy of software/computer • Receive previous MSD fixture • New action items • Add oil filter? • Add emergency stop?
