MOBILE DEVICE CHARGER PROPOSAL
Mike, Nicole, and Nick
To come up with a device that uses two alternate sources of energy to charge a
mobile device
OBJECTIVE
NEEDS AND REQUIREMENTS
To develop a solution that would be useful in many situations where a standard wall charger would not be available. (Ex. desert, out at sea)
Combine two different sources of alternative energy
Portable (small/light weight) Easy to use and safe Durable in extreme environments
IDEA #1“SHOE CHARGER”
Utilizes Kinetic and Thermal energy
Kinetic energy From movement inside sole
Thermal Energy change of body temperature
via the feet
IDEA #1“SHOE CHARGER”
Estimated Weight: 1 pound Easy to use. “as easy as putting on a shoe.” Affordable save you money in the long run
Disadvantages Restricted to using only that shoe Selection may be limited
IDEA #2“WINDMILL SOLAR CHARGER”
Utilizes wind energy and solar energy Wind energy taken from the wind Solar energy taken from sun
IDEA #2“WINDMILL SOLAR CHARGER”
Estimated weight: 2 pounds Easy to set up and safe to use Affordable price
Recycled materials
Disadvantages May end up not sunny and windy at the same
time Can only be used outside Not easily transported
FINAL PROPOSAL“SOLAR CRANK CHARGER”
Utilizes Solar energy and Mechanical energy Solar energy taken from sunlight Mechanical energy taken from when user
turns the hand of the crank
FINAL PROPOSAL“SOLAR CRANK CHARGER”
Device is easy to use and could be folded up and taken anywhere with ease
Hand crank enables the charger to be used indoors as well as out doors
FINAL PROPOSAL“SOLAR CRANK CHARGER”
SIZE AND WEIGHT
29in x 9in (unfolded)
5in x 9in x 1.25in (folded)
1 pound
SOLAR PANEL
Solar Power Output: 4 watt ( 5 V @ 800 mA)
Charging time: 1 to 2 hours
HAND CRANK
Maximum output voltage: DC 6V
Maximum output current: 300 mA
Battery charging time: 1 minute translates into 3-5 minutes of talking time
FINAL PROPOSAL“SOLAR CRANK CHARGER”
HOW IT WORKS
Sun Photoelectric Cells Battery USB Mobile
Device
Crank Coil Magnet Electricity
FINAL PROPOSAL“SOLAR CRANK CHARGER”
Main components are not too expensive and are easily available makes the device available at an affordable price
About $100 Solar Panel
Sells for around $100 Crank
Sells for as low as $5
