Tesla should soon be laser-spraying windshield dirt


Since its conception in 1903 (year of filing of the patent by Mary Anderson), the windscreen wiper has not evolved much. Rubber blade mounted on a swinging arm, it was not until 1951 that William M. Folberth made it automatic and 1963 that Robert Kearns equipped it with intermittent sweeping.

Lots of progress has been made since then with the addition of rain sensors, material work and aerodynamics, but ultimately it’s still a rubber blade rubbing on the glass.

Tesla goes laser

Tesla had been thinking about it for quite a while. In 2019, the brand filed a patent to use lasers to get rid of accumulated dirt. This is not a replacement for traditional brooms at this time, as lasers cannot drive water away, but a complement to maximize efficiency.

An optical system will detect the elements to be eliminated before treating the targeted area automatically (a forced manual control should also be added). A system that could also be adapted to other products such as solar panels, or any other system whose efficiency depends on its cleanliness.

The US Patent Office has just given its approval for Tesla to produce this new system, but it would be surprising to see it on a production car before next year (on the Roadster for example).

Tesla innovates, for the better or…?

The least we can say is that Tesla is committed to the progress of vehicles. With the constant growth of artificial intelligence, the manufacturer is gradually approaching a completely autonomous vehicle.

However, to want to be too much in the future, some technologies are put on the market without being perfectly functional. To stay in the field of the windscreen wiper, we can mention the lack of efficiency of the detection of the rain which passes through the neural network of the company instead of a classic sensor.

Indeed, in the ideal of Elon Musk, the Tesla will use fewer and fewer sensors and more and more processing of the images taken by the cameras of the vehicle thanks to artificial intelligence. A desire to reduce the complexity of the hardware, but unfortunately subject to the whims of the software.
