HW
Improve the function of the Bigbelly Solar brand trashcans in the Boston area. Aimed at removing snow from the top in the winter, which inhibits the function of the solar panels and prevents the trash from being compacted and emptied. This involved mechanism design, material selection, force analysis, machining, budgeting, and prototyping.
MECHANICAL TRASH CAN WIPER SYSTEM
PROBLEM >>>
The BigBelly Solar trash cans dispersed throughout Boston get covered in snow in the winter. This covers the solar panel, which prevents the solar-powered compacter from operating.
They are unsanitary. They overflow with garbage and the openings get stuck when the compacter doesn't work.
The handle is dirty. People do not want to use this trash can when it's not clean.
SOLUTION >>>
FINAL PROTOTYPE >>>
We machined all the parts and members to make an entirely mechanical prototype. We designed a wiper system to extend across the surface of the panel along a guide rail, activated by a foot pedal and requiring a reasonably small amount of force by the user, while simultaneously opening the hopper. This makes the trash can hands-free, while also using human power to clear snow from the solar panel.
