On-board Component Abnormal Site Identification Using Foreign Substance Variables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing on-board component abnormality detection systems face challenges in accurately identifying the site of abnormalities in transmissions, as they often rely solely on rotation speed changes and do not account for foreign substances in the oil, which can vary in type and concentration, leading to incomplete diagnosis.
Innovation Solution
An on-board component abnormal site identifying method that acquires and calculates values using foreign substance variables, including concentrations and color, in conjunction with deviation amounts and traveling distance, to determine the abnormal site with higher accuracy by employing mapping data and neural network-based calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only rotation speed changes are used for abnormality detection, then the detection method is simple, but the identification accuracy of abnormal sites is insufficient
Solution Approach 1:
The patent combines multiple detection approaches by merging rotation speed monitoring with foreign substance analysis in oil. The system integrates data from rotation speed sensors and foreign substance concentration measurements to comprehensively identify abnormal sites, achieving higher accuracy than either method alone while managing complexity through systematic integration
Solution Approach 2:
The patent introduces foreign substance concentration in oil as an intermediary indicator to bridge the gap between rotation speed changes and actual abnormal site identification. By analyzing foreign substances that result from component degradation, the system indirectly identifies abnormal sites with higher precision without directly monitoring each component
2Measurement precision
If foreign substance variables are included in the analysis, then the abnormal site identification accuracy is improved, but the complexity of data processing increases
Solution Approach 1:
The patent segments foreign substance analysis into distinct categories (concentration, type, size) and processes each segment separately. By dividing the complex foreign substance data into manageable segments and analyzing them individually, the system achieves high identification accuracy while controlling data processing complexity through structured segmentation
3Measurement precision
If multiple foreign substance variables (type, concentration, size) are analyzed, then the identification accuracy is significantly improved, but the measurement and analysis complexity increases
Solution Approach 1:
The patent replaces complex manual foreign substance analysis with automated measurement systems that use optical or electrical methods to detect foreign substance properties. By substituting mechanical/chemical analysis methods with modern sensing technologies, the system achieves precise measurement of multiple foreign substance variables while reducing measurement difficulty and operational complexity

AI summary
An on-board component abnormal site identifying method includes executing an acquisition process, a calculation process, and a reporting process by an execution device. The acquisition process is a process for acquiring, by the execution device, values of input variables. The mapping includes, as the input variables, a foreign substance variable, and includes, as an output variable, an abnormal site variable. The calculation process is a process for calculating, by the execution device, a value of the abnormal site variable by inputting, to the mapping, the values of the input variables acquired through the acquisition process. The reporting process is a process for reporting, by the execution device, a calculation result of the calculation process by operating a reporting device.
