Recently, electric car giant Tesla published patent for a new, magnetically focused wiper blade. The patent has held onto immense talk since its initial reports in early September 2019.
In the previous design, the wiper was comprised of two arms, identical in design, connected to a single wiper blade that stretched the height of the windshield.
The old design comprised of arms with fixed base to move the wiper across the windshield in a single motion. However, due to a flaw in the design, the wiper would not give full coverage to the windshield and the driver’s side would only be partially cleared. The wiper could not cover the main field vision and thus, would be a hazard to the driver.
New Wiper System
The new system is located under the vehicle’s hood. It is comprised of a single wiper arm that is connected to two horizontal bars, running the width of the car’s windshield.
Similar to the way a printer scans across a piece of paper to apply ink, the wiper arm would make its way across the windshield in a sliding motion with the help of magnets.
The magnets may retract the blade across the windshield, using an actuator or a gear. This design aims to give the blade a full coverage in a sweeping motion.
Upgrade for Roadster
The new wipers are designed to enhance the performance of Roadster. In order to prevent any wind resistance, its horizontal bars are upgraded and are located below the windshield— under the hood.
Tesla CEO Elon Musk frequently tries new things to improve the performance of Tesla products. The novel idea of magnetic wipers is one of them. It is curious to see them working in real time on upcoming Roadster supercar.
These changes are crucial for Tesla CEO, Elon Musk as he plans to have the Roadster run at the Nürburgring next year to break the one-lap record.
The company claims that the electric supercar could achieve 0-60 mph in just 1.9 seconds.
