The USA Patent Workplace has authorized Tesla’s revolutionary electromagnetic wiper design for the next-gen Roadster, paperwork present.
U.S. Patent Workplace paperwork reveal that patent quantity 10,889,267, the “electromagnetic windshield wiper design system” submitted by Tesla on March fifth, 2018, has been authorized. Tesla printed the patent over a 12 months in a while September fifth, 2019, and it was authorized on January 12th, 2021.
Tesla’s Electromagnetic Wiper for the Roadster
Tesla’s patent reveals a one-piece wiper design that’s not typical or comparable in any style to the “regular” two-piece windshield wiper structure. Most automobiles, together with all 4 of Tesla’s present lineup of vehicles, use two wipers that function from the underside of the windshield in an arc form. This provides the motive force protection of the visual view of the automobile they’re working, however it doesn’t clear each raindrop from the floor of the glass. The highest two corners, together with another areas, will not be affected by the standard wiper design or vary of movement.
Nonetheless, Tesla wished to put in one thing barely totally different onto its next-gen Roadster, which might be the quickest automobile to ever navigate on public roads. As an alternative of the standard two-wiper blade design, Tesla’s patent particulars a one-piece wiper system that makes use of an electromagnetic linear actuator to rid the windshield of any rain or moisture fully. It’ll begin from one facet and transfer on to the opposite facet, cleansing the whole windshield with one movement.
The patent states:
“The disclosed electromagnetic wiper system might embody a linear actuator that will embody a information rail and an electromagnetic transferring block. The information rail might embody a plurality of everlasting magnet bars which may be disposed horizontally alongside a curvature of the windshield of the automobile. The electromagnetic transferring block might act as an electromagnetic practice, and should embody a plurality of perforations and no less than an electromagnetic coil that surrounds the plurality of perforations within the electromagnetic transferring block. The linear movement of the electromagnetic transferring block via the plurality of everlasting magnet bars could also be managed to steer the wiper arm which may be coupled to the electromagnetic transferring block, backwards and forwards throughout the whole size of the windshield to wipe an outlined area, for instance, the whole clear space (i.e., close to cent % space) of the windshield. This may increasingly end in minimal friction in the course of the linear movement of the electromagnetic transferring block.”
When the wiper blade isn’t getting used, it will likely be hidden underneath the automobile’s hood. This provides to the Roadster’s clear and trendy design, freed from something that might take away from its aerodynamically-advantageous design, together with side-mirrors.
U.S. Patent Workplace Grants Approval
The USA Patent Workplace formally granted approval on January 12th, documents show.
“U.S. patent quantity 10,889,267 [Application Number 16/291,186] was granted by the patent workplace on 2021-01-12 for electromagnetic windshield wiper system. This patent grant is at present assigned to Tesla, Inc.. The grantee listed for this patent is Tesla, Inc.. Invention is credited to Nicolas Clift, Gonzalo Espinoza Graham, Maithreya Kedambadi Prasanna.”

Roadster Updates from Musk
Earlier this week, Tesla CEO Elon Musk gave some updates regarding the Roadster project, which has been delayed a number of instances because of engineering modifications and battery constraints. Musk informed Joe Rogan throughout his third appearance on the JRE Podcast that he desires the Roadster to hover and that he’s nonetheless making an attempt to determine how one can make that occur.
Musk mentioned:
“I would like it to hover. I’m making an attempt to determine how one can make this factor hover, with out, you already know, killing folks. I believed, perhaps we may make it hover, however not too excessive. So perhaps it may hover, like, a meter above the bottom, or one thing. So, for those who plummet, you blow out the suspension, however you’re not going to die. Perhaps, I don’t know, six ft. If we put a top restrict on it, it’ll most likely be fantastic.”
Whatever the Roadster will hover or not, Musk nonetheless plans to launch a SpaceX package deal that may give three tons of thrust for insane acceleration. Throughout the Q4 2020 Earnings Call, he additionally acknowledged that manufacturing would probably start subsequent 12 months.
Ending engineering this 12 months, manufacturing begins subsequent 12 months. Aiming to have launch candidate design drivable late summer season. Tri-motor drive system & superior battery work had been necessary precursors.
