KNOUNIDESIGNS.

The purpose of this project was to create a learning device that could be used in a museum or classroom that requires no instructions on how to use. This device attempts to teach the user of the Archimedes's Screw mechanism.
The Archimedes’ Screw is a machine historically used for transferring water from a low-lying body of water into irrigation channels. Its invention is attributed to Archimedes. It consists of a helicoid inside a hollow pipe. As the shaft turns the bottom end scoops up a volume of water. This water is then pushed up the tube by the rotating helicoid.
Instead of water, a steel marble was used instead. The helicoid was designed in SolidWorks and then was 3D printed. The casing and stands were made from transparent acrylic tubing and were bonded together with acrylic weld epoxy. The reasoning behind using transparent acrylic was to illustrate how the marble gets pushed up by the helicoid.
To minimize friction between the casing and the helicoid ball bearings were used at the top and bottom connections.
