Chilled by the process of scraping my windscreen clear of ice in the mornings, it seemed to me there must be a better way.
Today’s invention is an upgrade to the standard window cleaning device in which a magnetic handle is swept across the inside surface of a window, driving a magnetic pad to clean the outside.
Here, the external pad is equipped with a replaceable plastic blade (in the form of a credit card blank). This can be used to scrape at the ice on a windscreen -without having to stand outside.
The inside section could have a slender handle which would allow the far side of the screen to be reached from the driver’s seat and (if necessary) to carry a wire from the cigarette lighter to a heating coil inside the pad which is in contact with the screen’s inner surface.
This would work best in conjunction with a windscreen wiper motor circuit which, when sensing a fall in temperature below zero, would occasionally activate the windscreen wipers overnight and thus minimise the build-up of ice on the screen.
