Solution Overview

Problem

Current methods for sorting and recycling recyclable trash are labor-intensive, inefficient, and costly due to manual sorting processes, which hinder the effective reduction of waste disposal and resource consumption.

Innovation Solution

A trash sorting and recycling method utilizing a deep learning neural network to analyze images of trash and automatically sort recyclable materials into designated regions, reducing the need for manual labor by sending control signals to direct non-recyclable materials to non-recycling areas based on image processing and matching ratios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual sorting methods are used, then labor flexibility is maintained, but labor costs increase and processing speed decreases

Engineering Contradiction:
Improveprocessing speedVSAvoidmanual sorting requirement
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The patent replaces manual mechanical sorting with an automated system comprising image acquisition devices, deep learning neural networks, and robotic arms. The system captures images of trash, processes them through neural networks for classification, and uses robotic arms to automatically sort items into recycling or non-recycling regions, eliminating the need for manual labor while significantly increasing processing speed.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables trash sorting to perform itself through autonomous operation. The deep learning model automatically classifies trash items based on image analysis, and the robotic arm autonomously executes sorting actions without human intervention, making the entire sorting process self-service and highly efficient.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If deep learning neural network is used for image processing, then recognition accuracy improves, but computational complexity increases

Engineering Contradiction:
Improverecognition accuracyVSAvoidcomputational system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary action by pre-training deep learning neural networks with extensive trash image datasets before deployment. The neural networks are pre-trained to recognize various trash categories, and during actual operation, they quickly classify new items based on pre-learned patterns, achieving high accuracy without requiring complex real-time computation for each item.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The computational system is segmented into multiple independent components: image acquisition modules, neural network processing modules, and control modules. Each module handles specific tasks independently, allowing the complex deep learning system to be broken down into manageable segments that can be optimized and maintained separately, reducing overall system complexity.

Inventive Principle:
Principle #1Segmentation

3Productivity

If automated sorting system is implemented, then labor costs reduce, but initial investment and system complexity increase

Engineering Contradiction:
Improvesorting efficiencyVSAvoidsystem structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The automated sorting system is designed with universal components that can handle multiple trash types and categories. The deep learning neural network is trained to recognize various trash categories (recyclable, non-recyclable, different material types), and the robotic arm can adaptively sort different items using the same hardware platform, making the system multi-functional and reducing the need for specialized equipment for each trash type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A trash sorting and recycling method, a trash sorting device and a trash sorting and recycling system are provided. The trash sorting and recycling method includes: acquiring a detection image of trash to be sorted; processing the detection image with a deep learning neural network to judge whether or not the trash to be sorted belongs to recyclable trash; if yes, sending a first control signal, to control to deliver the trash to be sorted into a recycling region; if no, sending a second control signal, to control to deliver the trash to be sorted into a non-recycling region.
