Design Project II: Material Handling Dolly
The second design project was focused on creating a dolly which can lift a 35lb cylinder from a cradle, move it across a room and deposit it on a similar cradle. During the project I collaborated with my teammates in designing prototyping analyzing and testing our solution. During integration we had to revise the design on the fly due to issues with massive amounts of friction in the gearbox. Ultimately we pivoted from a 3D printed gearbox to a welded and machined metal gearbox allowing for tighter tolerances and higher rigidity.
When fabricating the creation of detailed drawings allowed all four team members to efficiently parallelize the fabrication process and reach the testing phase sooner, which proved to be critical in meeting deadlines later on.
Overall from this project I learned and practiced the engineering process, identifying and quantifying the problem, conceptualizing a solution, validating and iterating a design through technical analysis, fabricating, testing and documenting. Below you can find various different docuements and photos from the project as well as the CAD model.
