  1. E-GO Chrysalis Sanguk Andrew Park, Pare Chanoknun S., Maykie To Energy-on-the-GO

  2. Pare & Andrew somewhere in the jungle...

  3. Introducing E-go We provide... • Portable Power Charger • w/ Multiple Natural Energy Sources • Combination: Mix & Match - Fast & Convenient - Adjustable to different weather conditions • Attached to the backpack

  4. Table of Contents Product Development Process Product Specification Business Model

  5. Product Development Process

  6. Concept Development Identify Market & Problems Defining the Scope External Search Internal Search Exploring Concepts Concept Selection & Integration

  7. Problems Target Market: Outdoorsmen Not enough battery power for PEDs Lack of electricity outdoors Additional battery issues Subproblems: Existing natural energy portable chargers: Slow & weather constraint Inconvenience

  8. Defining the Scope: Mission Statement

  9. External Search

  10. Existing Portable Charger Brands • Problems • Too much time • Only one source of energy - Limited to certain conditions • Expensive

  11. Lead Users Comments

  12. Interview @ mountain Kim Young-Ik, 29, Ph.D Student Iphone 4 user “iPhone 4 Battery life is enough for one day hike, but overnight hike will require extra battery life without electricity”

  13. Interview @ mountain (cont’d) “Haven’t thought about buying a solar charger. Because I heard it’s expensive and inefficient. I need something more practical” Bae, Jung-Suk, 28 Occasional Hiker

  14. 1.Mix & Match with Cables Inconvenience Exploring New Concepts • 2. All-In-One • Bulky • Design & Feasibility

  15. Directly Connecting Energy Modules with Battery

  16. L E G O mechanism!!! Eureka~

  17. LEGO ModelPrototype #1 • Vertically attach with each module • Limitation • Constraint the capacity/size of each module • Power transferring problem: top & bottom and in between

  18. LEGO ModelPrototype #2 • (Bottom) Battery part • (Top) Energy modules • Flexible size for energy modules • Modules can be easily attached/detached from the battery

  19. Product Specification

  20. Prototype & Demonstration

  21. Product Specification • Battery: $20 • 1400mAh • Multiple Modules • 3.7 Volts (Charges Smartphones, camera, etc.) • Charging time: 3 HRs* (depending on numbers of energy modules) • 2 HRs with USB Ports

  22. Comparison to Existing Chargers

  23. Feasibility Check • Cases of combining multiple energy sources

  24. Cost Check Li-Polymer Battery: $6~ Small Solar Panel: $6~ Bike Dynamo: $7~

  25. Business Model

  26. How do customers buy our products? Battery (Platform) + Energy Modules of his/her choice $20 $15

  27. How do we make money? Profit from battery platform We Produce 3rd Party Manufacturers Royalty fee from energy modules

  28. Future Application • New Technologies Can Be Added as Modules! Static electricity Photosynthesis Piezoelectric

  29. Conclusion • Solves battery life inefficient problem, yet greener way • Captures lost energy • Reduces CO2 emission: contributes to greener earth • Open platform through standardization E-GO

  30. Thank you! Together, we can save the world
