Solution Overview
Problem
The recycling of aluminum alloy rims is hindered by variations in elemental composition and unknown compositions, leading to difficulties in grouping and processing, as existing methods lack efficient methods to utilize serial numbers for categorization and contaminant removal.
Innovation Solution
A method involving scanning aluminum alloy rims for serial numbers to categorize and batch them, followed by shot blasting to remove contaminants, using a data processor to determine appropriate processing based on composition ranges and contaminant thresholds, and allocating batches to specific manufacturers for targeted recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If aluminum alloy rims are recycled without categorization by serial number, then processing speed is maintained, but material composition accuracy deteriorates leading to quality issues
Solution Approach 1:
The system performs preliminary scanning and categorization of rims by serial number before processing. The database stores composition information associated with each serial number, allowing the system to pre-identify rim categories and prepare appropriate processing parameters in advance, thus achieving both accuracy and efficiency
Solution Approach 2:
The feed of aluminum alloy rims is divided into multiple batches based on serial number categories. Each batch is processed separately with composition-specific parameters, ensuring material accuracy while maintaining throughput by parallel processing of multiple categorized batches
2Reliability
If all aluminum alloy rims are processed together without batching, then processing simplicity is maintained, but contaminant removal effectiveness deteriorates
Solution Approach 1:
The system segments the rim feed into multiple batches based on serial number categories and composition. Each batch is processed separately through the shot blasting system, ensuring that contaminants specific to each alloy type are effectively removed while maintaining a relatively simple processing apparatus
Solution Approach 2:
The system uses feedback from serial number scanning and database lookup to determine appropriate processing parameters for each batch. The data processor adjusts shot blasting parameters based on the identified rim category, improving contaminant removal effectiveness without requiring complex manual intervention
3Measurement precision
If serial number scanning and categorization are implemented, then material grouping accuracy is improved, but processing time increases
Solution Approach 1:
Serial number scanning and database lookup are performed as preliminary actions before physical processing. The system quickly identifies rim categories and stores processing parameters in advance, allowing subsequent processing to proceed efficiently without repeated decision-making delays
Solution Approach 2:
The scanning, categorization, and processing operations are conducted continuously in an integrated workflow. Multiple rims are scanned and categorized in sequence while previous batches are being processed, maintaining continuous productive action throughout the system
