Iris Bin
OUR TRASHCAN MECHANISM IS INSPIRED BY THE MECHANICAL IRIS AND DESIGN IS INSPIRED BY HOW A CAMERA SHUTTER OPENS AND CLOSES. THIS MOTION-SENSING TRASHCAN USES AN ULTRASONIC SENSOR TO DETECT MOVEMENT AND AUTOMATICALLY OPENS THE FLAPS IN AN UNIQUE MOTION. THE MECHANISM IS POWERED BY A GEAR BOX MOTOR AND CONTROLLED USING AN H-BRIDGE (L298N) ALONG WITH AN ARDUINO UNO. WE INCORPORATED A TIMING BELT AND MULTIPLE GUIDE GEARS TO ENSURE SMOOTH AND SYNCHRONIZED OPERATION.

Drawing inspiration from camera shutters and aerospace iris mechanisms, the project explores how precision engineering can transform a common household object. The iris mechanism enables a compact opening system that expands to create a large aperture while occupying minimal space when closed.
Concept
Contactless and hygienic
interaction Space-efficient opening without vertical lid clearance
Improved odor and pest containment
Visually engaging and futuristic form
Large opening area in a compact footprint
Inspiration
Iris Bin is a motion-sensing smart trash bin that automatically opens when a user approaches. By eliminating physical contact, the system promotes hygiene and creates a more intuitive disposal experience in public and private environments.
