P16680: AATech Universal Oil and Bag System System Design Review 9/29/15 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) 2 P16680 System Design Review Objectives Confirm that all system goals are addressed in an acceptable manner Inform stakeholders of current project status Update engineering requirements if needed Review action items for team & customer 3 P16680 Agenda Use Scenario Engineering Requirements Constraints Functional Decomposition Systems Architecture Benchmarking Concept Generation & Selection Cost 4 P16680 Engineering Analysis Test Plan Risk Assessment Project Plan Lessons Learned Q & A Action Item Recap Updated Use Scenario 5 P16680 Engineering Requirements 6 P16680 Constraints 7 P16680 Functional Decomposition 8 P16680 System Architecture 9 P16680 Benchmarking Pumps Sensors Barcode scanners Microcontrollers Drain apparatus Height of table Door handles Oil lines 10 P16680 Morphological Chart 11 P16680 Concept Generation Three Potential Concepts Manual Concept Automated Concept Feasible Automated Concept 12 P16680 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 13 P16680 Concept Selection - : Less likely to meet criteria + : More likely to meet criteria s : Equally likely to meet criteria 14 P16680 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 15 P16680 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, P16680 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 17 P16680 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 18 P16680 Risk Assessment 19 P16680 Project Plan Gantt Chart thru 9/29 Rest of Project Next 3 weeks 20 P16680 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 21 P16680 Questions? 22 P16680 From previous review Receive oil requirements Receive copy of software/computer Receive previous MSD fixture New action items Add oil filter? Add emergency stop? 23 P16680 Action Item Recap
