This report describes a lesson in design in which students constructed a device as part of their training in tribology. The device consists of a launcher, a basket and a platform. Steel balls are launched and made to bounce three times on the platform before landing in the basket. By conducting preliminary experiments, problems were identified with the prototype and improvements were incorporated in the final design. The students learned new design methods. This exercise provided students with an opportunity to broaden their knowledge of steel materials, geometrical tolerances, guideways for rolling elements, mechanisms, and 3D-CAD. It is anticipated that design education will continue to incorporate the actual construction of such devices as an integral part of design education.
