  1. Don’t stop. 2.009 Fall 2004 Purple Team

  2. Video introduction

  3. Functional Requirements • Consistent power supply while running independent of a battery • Competitive quality and price • Ergonomic interface • No Running Interference • Durable

  4. Design evolution First generation User feedback Final design

  5. User Interface • Modular design (MP3 Player / Power Tube) • Sliding connector • Ergonomic design • Hip Belt docking • Unending power while running

  6. Internal components

  7. Internal components MP3 circuit (iRiver) Neodymium magnet Clear tube casing Detachable player casing MP4ever circuit 30 AWG magnet wire coil

  8. + - Battery How does it work!? ~ Reciprocating magnet Voltage MP4ever Circuit _ Voltage iRiver Circuit Coils Reflector magnet

  9. Number of coils Size of tube Gauge of wire Number of turns per coil Magnet / Coil details • Theoretical Model Predict effects of changing variables • Optimization Tests Final Design • Double Coil design • 1100 turns each • 6 in. tube length • 1 in. tube ID • 28 AWG wire Location of coil

  10. AC from coil Wave Rectifier Driver Chip Capacitor Bank Switching Regulator Output Filter Voltage regulation • Input 2 Hz AC 10 V Max. peak-to-peak 0.45 W Max. • Output 1.4 V 0.15 W Min. Steady Waveform

  11. Coil output Full Bridge Rectifier Capacitor Bank Switching Voltage Regulator Average = 5.5-10V Average = 1.4 V AC from coil Wave Rectifier Driver Chip Capacitor Bank Switching Regulator Output Filter Voltage regulation

  12. AC from coil Wave Rectifier Driver Chip Capacitor Bank Switching Regulator Output Filter Voltage regulation 50-80% Efficient

  14. Develop product alone • Requirements Raise capital Manufacture, market product • Evaluation No initial brand recognition Crippling initial start-up cost • Conclusion Might never regain initial capital

  15. License concept • Requirements Obtain patent Find partner, broker deal • Evaluation No running / production costs Collect royalties ~ 5% of sales (wholesale) • Conclusion Best option for profitability

  16. Cost and competition Competitor prices Flash memory iRiver 128MB $ 120 Sony-Philips 128MB $ 140 MPIO 128MB $ 114 Rio Sport 128MB $ 124 HD players Apple iPod 40GB $ 400 Apple iPod mini 4GB $ 250 CL NOMAD 30GB $ 228 Cost breakdown MP3 player circuit $ 5 128MB Flash memory $ 20 Circuit, coil $ 10 Magnets $ 7 Battery $ 2 Casing $ 1 Cost to produce $ 45 Wholesale price $ 90 MP4EverRetail price$ 150
