Mechanism Measurements
Used Math Illustrator to determine the correct 4‑bar linkage dimensions needed to move the trash tray from the top of the bin to the disposal slot without tipping. Verified forward and backward motion paths and ensured the tray stayed level throughout the sweep.
Recreated the mechanism in SolidWorks using the measured linkage lengths. Built a full assembly and ran a motion simulation to confirm the tray’s start position, end position, and the closest‑approach clearance between the tray and bin walls.
Captured images of the full trash‑can assembly, Math Illustrator geometry, the tray at its initial and final positions, and the minimum‑clearance point to document the mechanism’s behavior.
Verified the 4‑bar linkage geometry in Math Illustrator, ensuring the tray moved from top to slot without tipping.
Rebuilt the mechanism in SolidWorks using measured dimensions and ran a full motion simulation confirming forward and backward operation.
Captured the full assembly, Illustrator measurements, start and end tray positions, and the minimum‑clearance point inside the bin.
Demonstrated how theoretical linkage design translates into a functional mechanism with predictable, controlled motion.
