Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waste sorting systems face challenges in efficiently sorting waste plastics from mixed garbage due to the need for precise separation and the increasing volume of waste plastics, which complicates recycling efforts.
Innovation Solution
A waste sorting system utilizing air direction control, featuring a robot arm that grabs and moves waste on a conveyor belt using air suction force and releases it using air discharge force, accompanied by an apparatus for air redirection and an artificial intelligence model for target object determination based on a multi-class criteria table.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual sorting methods are used for waste classification, then operational flexibility is maintained, but sorting efficiency and productivity are low
Solution Approach 1:
The patent replaces manual mechanical sorting operations with an automated system that uses image recognition technology and controlled air flow mechanisms. The camera captures waste images, the processor identifies target objects, and air nozzles automatically grab and move sorted waste, eliminating manual labor while maintaining high sorting efficiency.
Solution Approach 2:
The system enables self-service automation where the waste sorting process is performed autonomously without human intervention. The image recognition system automatically identifies target waste, the control unit autonomously determines sorting decisions, and the air blowing mechanism automatically executes the sorting action, creating a fully self-operating sorting system.
2Adaptability or versatility
If traditional waste sorting systems are used, then basic sorting functionality is provided, but adaptability to different waste types and sorting criteria is limited
Solution Approach 1:
The patent implements dynamic adaptability by allowing the sorting criteria to be flexibly configured and changed based on different waste types and recycling requirements. The system can dynamically adjust its recognition parameters and sorting rules without requiring physical reconfiguration, enabling it to adapt to various sorting scenarios including different waste materials, colors, shapes, and sizes.
3Manufacturing precision
If air suction force is applied to grab waste, then sorting precision is improved, but energy consumption increases
Solution Approach 1:
The patent applies local quality by directing air flow precisely only to the specific waste item that needs to be sorted, rather than using broad air flow fields. The air nozzles are positioned and controlled to deliver focused air jets exactly where needed to grab and move individual target objects, minimizing overall air consumption while maintaining high sorting precision.
