AIR / SOUND WIPER BY TEJASWI LAVETI

2

Statement of the Business Idea

concept: AIR/SOUND WIPER

• Sound waves or compressed air used to clean the windshield of any vehicle.

• No wipers are needed, therefore electric motor is also not required.

• Reduce weight on the Vehicle front body

Current Description

• Wipers, electric motor requires maintenance• Wear and tear in time of the blades and rubber due to

frictional losses• Adds extra weight on the front portion of the vehicle• Operating noice• Reduce the overall performance of the vehicle( 2%)Problems: • Smearing of the wiper blades and the windshield

• Water beads that won’t wipe in all directions• Clogging of the water spray nozzle• Constantly monitoring the water fluid pump

Future Description

• No Chattering , Smearing of the blades• Improve the overall efficiency of the car, as this concept

will shed off the weight of the wiper and motor• Little maintenance costs• No wear and tear of the mechanical components• The burst of Compressed air / Sound waves will cover the

entire area of the windshield ( Uniformity).• No blurred windshield
