I saw some elastic bands recently designed to take up the shape of various animals etc in 2-D.
Today’s invention is to apply this idea to power cords for all sorts of electrical equipment.
The cord would be coated in a slightly stiffer than normal rubberised outer layer. It would thus be maintained in a planar layout, making it much more difficult to trip over and almost impossible to form tangles.
An appliance would still have some flexibility to be moved a small distance away from the wall socket, without drastically distorting the 2-D shape.
This could obviously be used to promote some related product by embodying a logo or message.
