Sat-Nav Solution
THE TASK• We were tasked to come up with a new product
to solve a problem in which users will or have faced
• The problem and the solution could be of our own choosing but would require investigation
• The solution would be one product and must be designed from the point of view from the user and cater to the users wants and needs
• We must produce and/or portray a prototype product as well as the idea of the finished product

PROBLEM IDENTIFICATIONNext we used the research we had gathered to identify the
problem we wanted to pursue:• We decided that we wanted to solve the problem of users;
in particular drivers of cars and vans; looking away from the road in order the receive guidance from their satellite navigation systems
• We found from research that there is a considerable percentage of road traffic accidents contributable to the use of ‘sat-navs’ and mobile phones for GPS assistance whilst driving
• Therefore we decided that their was a definite justification for a product to be created to resolve this problem
PROBLEM RESEARCHOnce we had identified our problem we did more
research related to it• Researching into various products which relate to the
problem• Researching into the different types of users of
various products• Researching into the success of various ‘other’
solutions• Compiling all of the research into mood boards• Below is an example of said mood boards:
PRODUCT CONCEPTS & DESIGN DECISIONSThe next stage was to begin to conceptualise the
product in which we wanted to create• Did we want the product to be similar to other
products already on the market place?• Did we want our product to be completely unique and
re-invent the wheel?• Would our product take advantage of future
technologies no necessarily available for commercial use at this time?
• How would our project be created?

ONCEPTS
PRODUCT CONCEPTS & DESIGN DECISIONS CONTINUED….• Our initial idea was to create a steering wheel mount
for a mobile phone which would allow the user to reduce the time their eyes spent away from the road
• We wanted to attach the mount to the centre of the steering wheel
• Problems with this included things such as:• Legal and safety issues involving placing objects over the
airbag• Issues causing the phone to spin with the wheel meaning any
readout would be impossible to view and use• Issues causing an obstruction of the drivers hands from
effectively turning the wheel
PRODUCT CONCEPTS & DESIGN DECISIONS CONTINUED….• This meant that our solution would need to be redesigned• The redesign and rethink would involve more research
into emerging technologies and in car safety• Our new solution was to create an attachment for phones
and sat-navs which would create a ‘Heads-Up-Display’• The attachment would be mostly transparent and placed
in the drivers eye line on top of the car dashboard.• This meant that the drivers eyes would not be taken away
from the road, but they could still receive the vital information that they needed

PRODUCT CONCEPTS: SKETCHES
Pro Screen can be hidden when not in use with
different suggested methods Simple user interface Design simplicity Simple manufacture
Con low stability (may fall over while in car) no way of connecting the phone to the
device Basic design may not intrigue consumers

PRODUCT CONCEPTS: PROTOTYPESHere is an example of a prototype model of the product:
PRODUCT CONCEPTS: SKETCHES
Here are some designs of the proposed products:
PRODUCT CONCEPTS: SKETCHESPro Good stability do to sticky pads Good incorporation of phone (text
message) High compatibility Hidden screen when not in use Traffic updates
Con Not eye catching Cluncky/Box design Screen to base connection looks weak and
may snap Different dashboard heights may prevent it
being invisible to driver as stated on design
PRODUCT CONCEPTS: PROTOTYPES
PRODUCT CONCEPTS: STORYBOARD
Here the satnav is located behind the steering wheel. The satnav is working but it doesn’t have anything to show the driver therefore the display is in the closed position.
Here the satnav is open, giving the driver clear instructions without hindering his view of the road. The satnav will stay open until the vehicle has completed the maneuver.
Here the satnav is closed. Once the maneuver is complete and there isn’t any more information to give it will close back down so it is out of site and not distracting the driver.

PRODUCT CONCEPTS: SKETCHESPro Display screen for extra information Suckers to stick to dashboard Simple interface LED making it more energy efficient USB making most phones compatible Interesting Design
Con Complex Moving part may be jammed Power source? Dashboards are often curved so the
straightness of this product may prevent it from attaching perfectly.

THE PRODUCT AND POWER • This product will need a power source in order
to function and would be best if it has both battery power and power through the cigarette lighter.
• The battery should also be rechargeable to make it more functional for this product.
• The cigarette lighter supplies a 12v dc power supply so the product must be made compatible.
Portable Power banksThese are used to give a mobile phone an extended battery life. They use a Lithium Ion battery to store the energy for the phone to then use as extra battery life. The lithium ion battery is also able to be recharged so can be used over and over again without the need to purchase a new one.

LITHIUM ION BATTERIESThese batteries are very popular and find use in laptops, mobile phones, iPods and other devices. The
batteries have become so common because they are some of the most energetic rechargeable batteries that are currently available.
Advantages over other batteries Much lighter then other batteries
Hold there charge well
Have no memory effect so do not need to be fully discharged before recharge
Can handle hundreds of discharge and recharge cycles
Disadvantages Start degrading as soon as they have left the factory
Degrade faster under higher temperatures
If completely discharged the battery is ruined
Requires an on-board computer to manage the battery
If the battery fails there is a slim chance that it will burst into flames

FINAL DESIGN SKETCH
JUSTIFICATION OF THE FINAL PRODUCT CONCEPTWe decided that we would go with Sam’s idea, a heads up display that is an oscillating LED strip. We went with this for a number of reasons:• The oscillating LED strip gives the impression of a floating screen, this means that
there isn’t a screen that could obstruct or distort the drivers view.• The device tapers down at the end, meaning that it looks like a piece of the car.
Because car dashboards are curved our device will have a curved base, this will follow the lines of the dashboard, making it look like its part of the dash.
• The small display will give the driver the destination, and other information they will need when setting up the device.
• There will be two ports. One will be used as a reserve power source incase the lithium ion battery runs out, this will also be able to charge the battery. The other will be a USB port that will be used to connect phones and other devices to the satnav.
• The device will be attached to the dashboard with suction feet, this will stop it moving when turning, or jumping off the dash when the car goes over a speed bump.
• There will only be a power button on the device, everything else will be controlled by the phone.

Ports
The minimalist style continues onto the back with only 2 external ports so you can simply plug in and go with the usb of the ultra fast usb 3 port to connect with any phone charger and a power cable to be plugged into the car.
This revolutionary new Sat-Nav display is in the forefront for road safety. The placement of this display, just behind the wheel, allows the diver to keep their eyes on the road and not obstruct their view. This slim stylish device looks at one with your car and the simple minimalistic button makes it easy to use for anyone.
Display
The oscillation of the LED stick means there is no screen that will obscure the windshield screen. The directions appear as if in mid-air as the LED lights corresponds with the oscillation to show simple and clear directions to follow. A second display screen is on the device to show the destination.
Size and weight
Front width – 15cm
Back width – 10cm
Front height – 3cm
Back height – 1cm
Depth – 15cm
Weight – 0.5kg
Body
The unique curved shape of this device lets it sit perfectly on top of your dash board and with its tapered end it makes the Sat-Nav looks like part of the car. The device sits on the dash by the use of its rubber feet so that it stays in place even with a sharp turn of the wheel.
