Do a prototype sketch on this description: ♻️ EcoBin – Smart Bin for Bottles and Cans ✅ What It Accepts: Plastic bottles Aluminium can drinks 🛠️ How It Works: User drops item into the bin. Step 1: Material Detection The bin uses sensors or weight detection to identify: Is it a plastic bottle? Is it an aluminium can? Or is it other trash? Step 2: Contamination Check The bin checks if the item is clean or still has liquid/food inside. If contaminated, the bin: Uses a simple internal rinse system (like a water spray and drip tray) to clean it. Then sends it to the correct bin hole. If clean, it goes straight into the correct bin hole. Step 3: Wrong Item Handling If the item is not a bottle or can, it is automatically sent to a separate bin so it doesn’t contaminate the recyclables. See more
