EspañolSQUARE WHEEL
(Redirected from Square wheels)
A literal 'square wheel' is a wheel that, instead of being circular, has the shape of a square. A more common use is as slang, meaning stereotypically bad or naïve engineering (see reinventing the square wheel).
A square wheel can roll smoothly if the ground consists of evenly shaped inverted catenaries of the right size and curvature.

A different type of square-wheeled vehicle was invented in 2006 by Jason Winckler of Global Composites, Inc. in the United States. This has square wheels, linked together and offset by 22.5°, rolling on a flat surface. The prototype appears ungainly, but the inventor proposes that the system may be useful in microscopic-sized machines (MEMS).
[4]
Square Wheels also represent a series of illustrations by Dr. Scott Simmerman of Performance Management Company (SC) about, "how organizations really work." The main illustration shows a wooden wagon rolling on wooden square wheels and being pushed by 3 or 4 people at the back and being pulled by a leader using a rope at the front. Communications between front and back is difficult and the view from the back is quite different from the view at the front. The cargo of the wagon is round rubber tires. The ideas for improvement already exist, but people are too busy working to make improvements.
