Motivation: During Hurricane Harvey alone, it is estimated that “as many as a million cars in the Houston metro area” were destroyed1. Floodwaters can corrode a car’s metal components, cause exhaust system failure, engine seizure and overheating, transmission failure, short-circuiting of wires, computer malfunctions, inoperative lights and dashboard, warped/rusted brakes and rotors, ABS malfunctions, airbag/restraint system failures, interior contamination, moldy seats/fabric, and bacteria in the car’s ventilation system. However, few cars are waterproofed and no device exists to reliably protect cars from floodwaters.
The Solution: Aütoflöt! A deployable automobile flotation device that lifts your car above the encroaching flood waters.
Design Considerations:
- Budget of $1000
 - Must be easily carried by average person
 - Must be reasonably stored in trunk of car
 - Must be deployable in under 15 minutes
 - Must be modular to fit multiple vehicle types with redesign or retrofit
 
Results:
- Total cost: $610
 - Full size weight: 150lbs – No single piece over 20lbs
 - Scale model setup time: 10 minutes
 - Maximum stable tilt angle: 50 degrees
