#872: Wiperwindow

It’s always interesting when a great idea gets stretched to the limits of applicability.

One such example is that of windscreen wipers. I was travelling in a bus the other day in which the wipers are over a metre in length. During heavy rain, these need to be flicked back and forth at a speed which is very much faster than is mechanically comfortable for them or effective.


Today’s invention is windscreen wipers for large screens. These move with non-uniform speed, wiping the central region, through which the driver looks most, for a large fraction of the time -only occasionally flicking over the distant corners of the driver’s field of view.

They might even repeatedly execute backwards and forwards oscillation over a central section of the window. This would, of course, require additional coordination between meshing pairs of wipers.
