  1. George Cameron Mobile charging device for electronics

  2. Back Story • Imagine that you are in a meeting on the phone and your phone dies with no way to charge it or continue your meeting.

  3. Initial Problem Statement • 3 Words: • Scavenging • Energy • Charge • Problem Statement • Today’s batteries die after prolonged use without a way to quickly charge them on the spot.

  4. Revised Problem Statement • Charging personal electronic mobile devices is inefficient and hard to accomplish without direct access to a power outlet. • Design a product that will harness energy in nature and process that power into a charging system

  5. Article Critiques - 1 • APA Citation: • Qin, Y., Wang, X., & Wang, Z. L. (2008, February 14). Access : Microfibre|[ndash]|nanowire hybrid structure for energy scavenging : Nature. Nature Publishing Group : science journals, jobs, and information. Retrieved November 5, 2010, from http://www.nature.com/nature/journal • Article Summary: • The article tells of a thread material that can harness kinetic motion and transfer it to a battery device. This will be critical to a mobile energy charging system. • Article Type: • Technical

  8. Patents • Patent Number: 2010/0276944 • Patent Description: Describes a process/system that harness power from motion of joints Pros -Compact -Efficient -Simple Cons -

  9. Patents • Patent Number: 2009/0095673 • Patent Description: Describes a system of taking solid organic waste and converting it into a fuel. Pros -Efficient -Recycles -Power Generating Cons -Large -Complicated -Must be maintained

  10. Patents • Patent Number: 2006/0192386 • Patent Description: Describes a system that harnesses the energy from the up and down motion of walking. Pros -Motion Charging -Compact Cons -Backpack -Large

  11. Where We Are Going • A clip system that can be clipped onto almost any material and can harness kinetic motion energy.

  12. Sketches Power Shirt/Power Glove Power Clip

  13. Power Glove • Takes the movement of fingers to rotate electromagnet creating current. • Current harnessed to charge battery. • Charge pad in the palm to wireless charge mobile device.

  14. Power Suit • The material of the suit is a piezoelectric system designed to harness all movement of the body to a central power location. • Currently not feasible.

  15. Power Clip • Modular design to minimize weight. • Central unit designed to process power to a battery and then to mobile device. • Most feasible.

  16. Requirements • From the survey we have given, we have discovered that the product must have the following requirements, and the nice to haves would come later.

  17. Solution Justification and Product Specifications

  18. Decision Matrix

  19. Math and Science Concepts • PE=KE, so KE=mgh for potential vertical motion • Using the walking motion, a magnet can be accelerated up and down changing mechanical to electrical energy (V=I x R (Voltage=Current x Resistance)) • The energy can then be stored in a battery for later use.

  20. Summary • Key Requirement: Charge Mobile Device • Where we are going: Power Clip • Any questions?
