The goal of this MQP was to design and create a prototype of a device which will clean the surface of the dental mirror and restore its reflective qualities during a dental procedure. The project progressed through the engineering design process to a final design and working prototype. After research and consultation with dental professionals, the team created an initial list of design concepts, out of which a wiper-based mechanism was selected. The design concept evolved through the use of several modes of testing and analysis until a final design was reached. The final design is a variation of a slider-crank that utilizes the material properties of its components to clean the mirror through deflection of one of the links. Lastly, recommendations for continuing this project are included.
