Mobile charging device for electronics

MOBILE CHARGING DEVICE FOR

ELECTRONICS

GeorgeCameron

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.

Initial Problem Statement 3 Words:

ScavengingEnergyCharge

Problem StatementToday’s batteries die after prolonged use

without a way to quickly charge them on the spot.

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

Where We Are Going A clip system that can be clipped onto

almost any material and can harness kinetic motion energy.

SketchesPower Shirt/Power

GlovePower Clip

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.

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.

Power Clip Modular design to minimize weight. Central unit designed to process power

to a battery and then to mobile device. Most feasible.

•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.

Solution Justification and Product Specifications

Decision Matrix

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.

Summary Key Requirement: Charge Mobile

Device Where we are going: Power Clip Any questions?
