2
Identification of a Need

PROBLEM Inconvenience for drivers in below
freezing temperatures
NEED An automatic device that will clear the
windshield of frost and ice

3
Problem Definition

Designing a mechanism that will eliminate solid
precipitation on windshield
We want the device to be automatic to reduce
driver inconvenience

4
Search

Triplex Safety Glass Co. has developed a
windshield film called Hyviz
Visteon/Southwall collaborate to design a
windshield film called XIR
Nano-tubes
Rear window defrosters
Ice scrapper
Garage
Solar cells and batteries
Temperature Sensors

5
Constraints

Visibility
Size
Battery - must fit in original car design
Safety must be able to crumble with glass

6
Criteria

Cost of production verse profit
Types of materials used
Appearance of exterior parts
Automatic Device

7
Alternate Solutions

Ice Scraper
Garage
Powered by car battery
Solar Powered Device (Using either conductive
film or nano-tubes)

8
Analysis Ice Scraper

PROS CONS
Save Loss of time
Expenditure of personal Energy
Out in the cold

9
Analysis - Garage

PROS CONS
No frost/snow Expensive to construct
Saves time Not everyone has a garage May
not be room for all needed cars

10
Analysis Car Battery Powered Device

PROS CONS
Lower cost May drain the battery
Saves time

EST. BUDGET
HIGH LOW
CAR BATTERY 80 (12V) 40 (12V)
TEMP SENSOR 150 40
NANO-TUBES 1,000 (2mm long) ????
XIR OR HYVIZ FILM ???? ????
11
Analysis Solar Powered Device

PROS CONS
Decreases fuel emissions Cost
Saves gas
Saves time

EST. BUDGET
HIGH LOW
SOLAR BATTERY 75 (12V) 13.95 (12V)
SOLAR CELLS 55 (12x8.75) 45 (11x8.75)

Hyviz Data

Want a film with a resistance of .52 ohm/square
Wv2/r
Wtotal power in watts
Vsupply voltage
rresistance load in in ohms
WV2/r(sq)d2
ddepth of windshield between busbars
r(sq)ohms/square area
Wpower density in watts/in2
Vsupply voltage

Graph of defrosting times at 0 ºF
15
Specifications of Hyviz Film
Film thickness is around 3000 Angstroms With
this thickness there is around 80 transmission
of visible light through the windshield. Any
power density over .5 W/in2 needs a temperature
sensor to avoid overheating and to conserve power
16
Decision

To satisfy the Constraints Criteria as best as
possible while considering the Identification of
the Need, we will choose the Solar Powered Device
Automatic system
Saves time
Fits all existing vehicle qualities
Not an unrealistic production cost
