Toy Counter Design (DE GearMates)

As part of MECE3408, I co-developed DE GearMates, a fully mechanical, screen-free educational toy that teaches 5-year-olds single-digit addition and subtraction through kinesthetic learning. The toy uses a gear-based interface featuring Geneva mechanisms to translate user input into accurate arithmetic outputs. All parts were modelled and assembled using the SolidWorks software. Design intent was considered throughout the creation of the project to facilitate future redesigns and adjustments while taking into account our objectives. For further details on the project please view the final report document below.

A physical prototype was developed using available materials. Acrylic gears were laser cut while Geneva Movers were 3D printed. Magnets served as pivot points. The addition and subtraction functionalities were both included. The primary mechanism successfully demonstrates digit summation and subtraction through gear synchronization and mechanical logic.
