Automated Feedstock Identification via Image Annotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual data entry in recycling facilities for quality control is time-consuming, prone to errors, and limits the processing and analysis of data, preventing effective statistical evaluation and visualization of historical data, and lacks the ability to tag contaminants for supplier discussions and future image recognition.
Innovation Solution
A tool-based recycling feedstock identification method that involves recording images, annotating data identifiers for impurities, evaluating quality levels, and connecting to ERP systems, using barcode scanning, and enabling deep learning for improved data processing and decision support, with pre-defined categories and dashboard functionality for quality control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual data entry is used for quality control, then flexibility in data recording is maintained, but time consumption and error rate increase significantly
Solution Approach 1:
The patent replaces manual mechanical data entry with automated optical character recognition (OCR) technology. The system captures images of feedstock and automatically extracts and records data, eliminating the need for manual typing while maintaining recording flexibility through configurable data fields.
Solution Approach 2:
The system creates digital copies of physical feedstock through image capture and stores them in a database. These digital copies can be repeatedly analyzed, shared, and processed without additional time cost, unlike manual entry which must be repeated for each analysis.
2Device complexity
If manual data entry is used, then no additional hardware is needed, but data accuracy and reliability deteriorate due to typos and wrong entries
Solution Approach 1:
The patent replaces error-prone manual data entry with automated image recognition and data extraction systems. The OCR technology and automated processing eliminate human errors such as typos and wrong entries, significantly improving data reliability.
Solution Approach 2:
The system implements automated feedback mechanisms where captured images are immediately processed and validated against predefined criteria. Any anomalies or errors are automatically flagged for review, creating a closed-loop system that continuously improves data accuracy.
3Loss of information
If local electronic storage is used, then data accessibility is improved, but processability and statistical evaluation capability are lost due to free-field entries
Solution Approach 1:
The patent segments data into structured fields with predefined categories and data types. Each feedstock attribute is stored in a specific, standardized format rather than as unstructured free-text, enabling automated processing while maintaining full data accessibility through the digital storage system.
Solution Approach 2:
The system transforms unstructured free-field entries into structured data with defined parameters and constraints. By changing the data organization from flexible text fields to structured databases with predefined schemas, the system enables statistical evaluation and automated analysis while preserving data accessibility.
4Adaptability or versatility
If manual picture management is used, then storage flexibility is maintained, but the ability to tag and analyze contaminants is lost
Solution Approach 1:
The patent replaces manual picture management with automated image processing and recognition systems. The system automatically detects, tags, and categorizes contaminants in feedstock images using computer vision algorithms, eliminating the need for manual annotation while preserving storage flexibility through digital file management.
Solution Approach 2:
The system creates annotated digital copies of original feedstock images with automatically generated metadata tags identifying contaminants. These enriched digital copies retain the original image quality while adding structured information layers that enable automated analysis without compromising storage flexibility.
