Purdue MET 10200: Glass Bottle Catapult
Autodesk Inventor Professional 2022
Assembly Modeling & Documentation
In this project, I had the opportunity to design a machine that would either crush a can of soda or break a glass bottle. The machine had to incorporate a chain and sprocket drive system or a belt drive system, a minimum of two simple machines (lever, wheel and axle, pulley, inclined plane, wedge, or screw), at least one type of bearing, one motor, and proper welding or mechanical fasteners. Additionally, the machine had to fit on a surface that was 30 inches wide and 60 inches long.
I decided to create a machine that would break a glass bottle as I believed it would be more entertaining to experience than a soda can being crushed. I started by developing a series of detailed sketches that indicated the layout of my machine and how all of the criteria were utilized throughout the design. I had to present these sketches to classmates for feedback, and further design or source all of the brackets, supports, and table mounts that I decided to use. I had to consider the use of standard parts as it would reduce the cost and time to acquire such parts. Additionally, I had to consider technical standards and apply fits or tolerances to ensure proper functionality.
The deliverables of this project included a full set of mechanical drawings that depicted all parts utilized. This included a fully annotated assembly drawing as well as individual drawings for all custom parts. I also had to provide a drawing for my gear, chain/sprocket, or belt drive systems to gain practice on how to develop such mechanical drawings. This project not only allowed me to develop my technical skills, but also gave me the opportunity to think critically and creatively about the design process.
