KING KONG cybertruck wiper not very futuristic...here is how to produce the look this trucks deserves...

[CyberGus]

I wonder why they felt the need to wipe the greyed out area? That is a lot torque to overcome for an area not required for road visibility.

The blacked-out wishbone area at the top of the windshield is where the AP cameras are. The wiper needs to keep this area clear.

Elon calls every under the hood stow 'in the frunk'. It's not an engine bay, right?

-Crissa

I just reread Elon's comment and I think that I misread or misunderstood him. When he says 'stows in the frunk' for the electromagnetic wiper he doesn't mean 'is removed and stored in' but, rather, 'is situated in'. So we are both right after a fashion.

What I am unclear about is why that is so difficult. The hood section might not be a part of the exoskeleton but isn't it also the same 3mm stainless? It has to be hinged off something pretty darned sturdy so why couldn't it all be moved back a bit? I have looked at a lot of hoods and they kind of floatover the engine or frunk compartments.

How is the wiper ugly? Looks like a normal wiper to me, just not hidden. Given the functional design of the cybertruck in general - anything efficient should be fine.

I'm worried that with magnets on the inside and outside of the glass being the only thing holding the wiper on... someone could simply walk by, pop it off, and walk away with your wiper.
I don't like it in high winds either.

Magnets strong enough to prevent these problems lead to other problems. Any little iron particle that happens to float by is now seriously scratching your glass, if not affecting operation in worse ways.

Also, exactly how thick is the glass? You'd have to start with some pretty powerful magnets for it to work at all, before overcoming the other problems.

Unfortunately due to the entire shape of the front end I just don't see any elegant solution yet to wipers on the CT. Most vehicles on the down stroke of the wipers push water down and a large portion of the water goes into the channel and moves off horizontally from the windshield. Because the CT design has no channel all of the water pushed down as well as all of the water on the frunk simply pushes back up to the windshield while the vehicle moves forward.

Thanks for that video

I was actually thinking about holes in the window for the wiper connection.

Rev 2 - The drivers side is now longer to cover the entire bottom of the window and the passenger blade is staggered up and it is shorter. The passenger side has a very short stroke and takes care of the camera. (I think) Synchronizing is key. Maybe the passenger blade goes every other stroke of the main wiper.

The advantage of the vertical position is that most water should shed without the blades at all as there is nothing for it to get hung up on. (horizontal stored blades)

With some rain-x type product maybe the only time you would need the blades is with a muddy splash.

To respond to the windshield thickness question, the patent application for armored glass talked a minimum thickness of about 1/4" thick which is about the thickness of the Model Y laminate. The patent talks about thicknesses from 0.5 mm up to 500 mm so it could be just about any thickness over 1/4”..

because any sort of mechanical cover to deploy a concealed wiper device would be frozen over in ice. ... unless that entire mechanism was heated.

...which is worse than the wipers covered in ice how?

I'm wondering if the rumor is that the wiper is made by Berg Regen, an aftermarket parts company. Otherwise, the rumor makes no sense to me.

UPDATE! Try as I might, I cannot find a patent for a regen wiper. But the Electric Viking talks about it here.

The collecting magnetic debris could be a problem for a linear drive wiper. But this could be overcome with the right wiper design to eject and clear debris from the linear motor pathway, and limiting the area it is magnetic.

For example to keep the wiper in place when stowed one could use a mechanical "cubby" or bracket mounted on the a-pillar to stow the wiper into or on or under. You could then delete the electropermenant magnets for stowing which means it will no longer collect magnetic debris when stowed and will mechanically inhibit theft.

Also the wiper would have magnets, or possibly only a ferrous steel plate to as a part of its structure that is embedded into the rubber to make it magnetic on the top and bottom of the wiper. The main magnetic force however would be the electro magnets(coils) from the linear drive that can, and have to be, modulated for it to move. The linear motor can be embedded to keep the gap to the wiper at minimum. The actual wiping blade that covers the most of the screen would not be magnetic at all.

The always vertically orientated wiper blade also means water ejection is on either side and water, debris and snow does not get pushed down horizontally so it can run back up the windscreen. This is a valuable benefit of a vertical wiper design and unlike a standard two blade design doesn't "shuffle" what is being wiped around the windscreen.

If the wiper storage cubby is on the sides, how do you keep the vertical wiper from filling up the cubby with snow & ice or if cubby has a cover, piling snow & ice blocking the cover?

 

[Albern]

Perhaps one of these ideas will make it to production. The current wiper reminds me of one of those AMG GT racers that had a massive hingeless blade right up the middle of the windscreen. I'm not bothered by what's on CT but there is room for improvement.

wipers covered in ice can be cleared of that ice....I do it daily every winter.

Doors covered in ice can be cleared of ice, Door made of steel I'm not afraid of breaking as I do it, either.
