  2. Design Activities • Customer Needs Assessment • External Search • Concept Generation • Morphological Chart • Pugh Charts • Triz • Final Design

  3. Project Management Order of Tasks to be Completed • Lighting Type • Type of Battery • Location of Battery Within Cabin • Location of Lights Within Cabin • Casing to Protect Battery • Wireless Capabilities • Design Meets All Necessary Requirements

  4. Weighted Hierarchal Customer Needs List • 1.0 Durability (.225) 1.1 Lights withstand crash and weight of people 1.2 Battery withstands crash • 2.0 Brightness (.205) • 2.1 .5 LUX in General • 2.2 2.5 LUX on Stairs • 3.0 Visibility (.177) • 3.1 Lights are easily distinguished • 3.2 Doors and stairs are visibly lit • 4.0 Time Requirement (.142) • 4.1 Emergency lights remain lit for a minimum of 20 minutes • 4.2 Lights can be manually shut off at any time • 5.0 Power Source Accessibility (.125) • 5.1 Battery can withstand a crash • 5.2 Battery is incased in a protective area • 5.3 Easily accessible • 5.5 In close proximity to cabin to be wired to lighting system • 6.0 Battery Source (.069) • 6.1 Wirelessly connected to train’s main battery source • 6.2 Wired to backup battery • 6.3 Enough energy to sustain appropriate LUX requirement for necessary amount of time • 7.0 Cost (.041) • 7.1 Lowest Possible Cost • 8.0 Visual Appeal (.017) • 8.1 Color indicates an emergency path

  5. Revised Problem Statement After researching the problem, we came to the conclusion that there were three main problems we had to solve. We had to decide on a power source that would be able to provide the lighting system with enough power to meet the requirements, where the power source would be located so it would not be damaged in the event of a crash, and which type of lighting would be best to illuminate the area to the specifications of GE.

  7. Concepts Generated for Power Supply Battery Gas Powered Generator Solar

  8. Concepts Generated for Lighting Types Photo luminescent LED Fiber Optics Incandescent Fluorescent Halogen Bulbs

  9. Generated Concepts for Location of Power Supply Nose of Cabin Underneath Elevated Area of Cabin Ceiling of Cabin

  10. Generated Concepts for Housing Power Supply Steel Aluminum Plastics

  11. Generated Concepts with TRIZ • Power Supply – Complexity of Device vs. Manufacturability • Power Supply Casing – Harmful factors acting on vs. reparability • Lighting Type – Brightness vs. Energy expended • Power Supply Casing – Durability of object vs. Volume

  13. Concept Selection (Power Source) • Choices for the power source, solar panels and a battery. • The battery was the best choice because it would have less damage during a crash, cost less and would be able to supply a constant source of power no matter the weather unlike a solar panel.

  14. Concept Selection (Battery Location) • Choices: Ceiling, Nose, and Underneath the Elevated Area of Cabin • Underneath the raised seat would not be as easily accessible but because of the harder accessibility would provide more protection for the power source and is the best choice.

  15. Concept Selection (Lighting Type) • The three options for the type of lighting are LED’s, fiber optics, and incandescent bulbs. • LED’s were the best choice because they will be able to provide the required lighting, cost less, and are more durable.

  20. Calculations Power Calculation 110 lumens x (1watt/660 lumens) x 6devices = 1 watt 110 lumens / 9.29 m2 = 11.8 LUX Total Cost = $1093.57 We feel this cost is reasonable because the majority of our cost comes from the LED lighting but we feel that the cost needs to be compromised for the overall durability of the design.

  21. Concluding Remarks • 1) The LED lights throughout the cabin provide sufficient illumination, to allow for safe egress from the locomotive cab in the event of a collision. • 2) Emergency interior lighting will be linked to the emergency brake and be able to operate for well over the minimum of 20 minutes, also illumination of our system reaches 12.2 LUX which is well over the minimum. • 3) Emergency interior lighting will operate in all equipment orientations. • 4) The emergency lighting battery power source will provide for a manual reset to extinguish emergency interior lighting.
