CREATIVE MECHANICAL DESIGN & MANUFACTURING

About the course

This course provided an opportunity to gain valuable insights into the principles of mechanical engineering and systems dynamics. Throughout the course, concepts including energy transfer, momentum conservation, constraints, stress, and the significance of motorization in maintaining perpetual motion were applied in the creation of an innovative mechanical design.

A network of interconnected mechanisms forms what is known as a “marble machine,” through which 20 mm steel balls navigate a series of obstacles. The entire system is motorized, enabling it to operate continuously in an endless cycle. When a ball reaches the lowest point of the system and loses momentum, it is lifted back to the initial position, ensuring the cycle continues uninterrupted. This machine comprises 7 distinct mechanisms. The journey of the ball begins at an elevator, where it is raised to the starting point. From there, it moves on to a “seesaw swing”, which serves as a junction between two divergent paths. The first path leads to a mechanism named “Pillars”, followed by “90° swings”. Subsequently, the path curves 180°, guiding the ball back to a rail spiral that leads directly to the elevator. The alternative path leads to a mechanism known as “Two masses on a pulley”, where the ball takes a brief ride on a cart. Finally, the ball traverses bumpy rails that curve into a pair of funnels before returning to the elevator, thus completing the loop.
