Wipers for a VERY curved screen....
Looking for some good ideas on how to wipe a very curved screen, a traditional wiper would just fly off the screen if you tried to move it at any
speed. Any examples of people attempting this?
Thanks,
James

Look at the LeMans race cars and the solutions they use on them.

That was my first thought, but it looks like the curve is low enough to use a traditional setup...

I think what ever you come up with Rainex solution on the screen would be a big help.

It's purely for IVA reasons rather than practical! The manual doesn't give a very clear idea of how much of the screen needs to be
swept...

I would imagine anything within the drivers vision as with cracks or chips.

How about the kind of system they self clean cctv cameras with? there as a design for a dome camera years ago where the blade was secured at the top
of the dome and the bottom and the blade cured to suit the profile. It them rotated through 360 degreees and dragged the water droplets off.
Just a thought

You might be able to modify or make a track so that the blade parks at the top and wipes downwards. If the blade is curved upwards then the water
will move outwards.

The trick with very curved windscreens is to keep the wiper vertical as it sweeps.

Which would lead down to a design of a tracking wiper rather than a rotating one.... cogs whirring

if you built a wiper that attaches to a cog wheel vertically then then driven by motors like a normal wiper would that work?
 
DOES THIS MEAN ANYTHING TO ANYONE OR WAS MY MONDAY am WORK RUBBISH LOL
Its not in perspective but it should work if the cog is the same shape as the window and the axis is set right.

look at the countach wiper arm, a variation on that would probably work though you could do with a rocking motion as well as a side to side

Yep the diagram makes sense - and might work! Just need to think where to park it out of sight...
Can't quite fathom what the countach one is doing, it looks like it's keeping it vertical?

Just replaced the wipers on my Passat. Only apparent when you see them off the car, but they are very bowed and achieve a really good pressure right
across the screen (albeit a much flatter screen). Might work if you can mount them OK, they have a push button fixing rather than the old hook type.
Beware if you buy a pair as they're 2 different lengths.

In which case is leaving the screen off for IVA an option?
Not very Locost but very BEC

I think I have the mechanical solution - just requires a mount oscillated by a normal windscreen motor, and a high angle rose joint at the fixed
end... Should countour around the screen and keep the blade angle against the screen constant....
Too barmy?

It's OK I saw where you were coming from! - by adding the fixed pivot to that it also parks more in line with the body down the side
