  3. Executive Summary • Background • Current System • Client’s new production needs • Design Challenge • History • Rules

  4. Project Description • Create a jig to increase production of cardboard bumpers, while also allowing for a wider range of employees to use the device • Features: • Low cost to build and maintain • Provides mechanical advantage to operator • Simple notification system

  5. Diagram of Systems

  6. Subsystems • Mechanical • Racking System • Clamping System • Electrical • Sensors • Indicators • Sensor control logic • Power Supply • Ventilation

  7. Racking System

  8. Clamping System • Two Part System • U-Bolt Lock • Connective Pin

  9. Mechanical Analysis Force Analysis Speed Analysis Max: 25, Min: 11, Avg: 17.22 Max: 63, Min: 44, Avg: 53.1

  10. Sensors Single unit with LED and phototransistor

  11. Sensor Control Logic Circuit

  12. Gate Level Logic

  13. Containment and Ventilation • Clear acrylic box cut to size • Cheap • Effective • Running temperature nearly indistinguishable from room temperature while outside the box • Positioned small vent holes on sides and top to allow for moderate airflow

  14. Indicator LEDs • Indicators are RGB LEDs • Low cost and long life • Indicators use a well-known pattern

  15. Power Need the jig to be able to use standard 120 volt alternating current Components require a 5 volt direct current

  16. Overview of Device Operation

  17. Responsibilities Ben – Construct and integrate clamping system Jordan – Construct and integrate racking system John – Construct sensor controller, calibrate sensors, mount components in the case, attach the case to the jig Linden – Solder the power supply, attach power supply to the control logic circuit

  18. Cost (Mechanical Subsystems) Mechanical Subsystems Costs

  19. Cost (Electrical Subsytems)

  20. Time Required to Build Prototype

  21. Potential Improvements • Mechanical Improvements • Adjustable Base • Machined Parts • Width Adjustment for Feed Slot • Electrical Improvements • Adjustable sensor mounting • Better Case

  22. Summary Electronic jig Clamping system User friendly Cheap to build and maintain Small improvements can be made
