Innovation Solution
A system that enables concomitant testing of multiple wheels and rims at multiple locations, integrating eddy current array probes, X-ray fluorescence analyzers, and high-resolution microscopes with predictive modeling and machine learning algorithms for data analysis and predictive maintenance, communicating results through computing systems and ERP systems for improved accuracy and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wheels and rims are shipped to a central facility for inspection, then inspection can be conducted using Magnetic Particle Inspection, but logistics become cumbersome and 50% of wheels and rims shipped are in good condition yet still require shipping
Solution Approach 1:
The patent replaces the mechanical shipping process with electronic data transmission. Portable inspection devices collect data at mine sites, and this data is electronically transmitted to central facilities for analysis, eliminating the need to physically ship wheels and rims while maintaining inspection reliability
Solution Approach 2:
The patent introduces portable inspection devices and electronic data as intermediaries between the wheel/rim and the central facility. These devices enable inspection to occur at the mine site while allowing central facility experts to analyze the collected data remotely, serving as a mediator that bridges the gap between field inspection and expert analysis
2Ease of operation
If visual assessment is used for inspection, then the process is simple, but the assessment is dependent on the skill and experience of the assessor
Solution Approach 1:
The patent replaces human visual assessment with electronic sensing devices that objectively measure wheel and rim conditions. Sensors detect cracks, wear, and other defects through electromagnetic fields and acoustic emissions, eliminating dependence on human skill while maintaining operational simplicity through automated data collection
Solution Approach 2:
The patent implements feedback mechanisms where inspection data is immediately processed and analyzed by algorithms that compare readings against known defect patterns. This automated feedback loop provides objective, consistent assessments that are not influenced by human variability while keeping the inspection process simple through automated decision-making
3Ease of manufacture
If data are manually entered for archiving, then the process is straightforward, but electronic data acquisition and storage capabilities are lacking
Solution Approach 1:
The patent replaces manual data entry with automated electronic data acquisition systems. Sensors and inspection devices automatically capture and digitize inspection results, eliminating manual transcription while enabling comprehensive data storage, analysis, and long-term archiving with complete information retention
Solution Approach 2:
The patent performs data acquisition and digital storage as preliminary actions during the inspection process itself. Data is captured in electronic format at the source and immediately stored in databases, preparing it for future analysis without requiring subsequent manual entry steps
4Ease of operation
If eddy current array testing is conducted on site, then inspection can be performed at mine sites, but it only provides information on the current state and does not provide insight into health and remaining useful life
Solution Approach 1:
The patent performs preliminary actions by collecting historical inspection data and material properties before conducting current inspections. This baseline data is used in conjunction with current readings to predict future behavior and estimate remaining useful life, enabling proactive maintenance planning
Solution Approach 2:
The patent implements feedback loops where current inspection data is continuously compared with historical data and predictive models. This feedback mechanism updates predictions about wheel and rim health trajectories, providing evolving insights into remaining useful life based on accumulated evidence from multiple inspection cycles
