Tire Performance Characterization Using Precomputed Coefficients
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining tire performance characteristics, such as tire pressure and temperature, are time-consuming and lead to latency in providing maintenance actions, especially in aircraft tire monitoring systems, due to the large volume of data that needs to be processed and retrieved.
Innovation Solution
A method and system that utilize a performance coefficient based on historical tire parameter values over a first time period, allowing for quicker determination of tire performance characteristics by using this coefficient in conjunction with more recent data, thereby reducing the need to process and retrieve large volumes of current data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the first plurality of values are used to determine the tire performance characteristic, then the determination is more accurate, but the time required increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing performance coefficients during a first time period based on the first plurality of values. This pre-processing allows the system to quickly determine tire performance characteristics during the second time period by using the stored coefficients with minimal additional data processing, thus maintaining accuracy while reducing determination time.
2Loss of information
If the first plurality of values are retrieved from memory, then the determination can be made, but the retrieval time increases latency
Solution Approach 1:
The patent extracts and stores only the essential performance coefficients in memory during a first time period, rather than storing and retrieving the entire first plurality of raw values. This extraction of critical information reduces memory retrieval time and latency while maintaining the ability to accurately determine tire performance characteristics when needed.
3Device complexity
If a performance coefficient is stored and retrieved, then the processing is simplified, but the system requires additional memory storage
Solution Approach 1:
The patent transforms the original plurality of tire parameter values into condensed performance coefficients that capture the essential performance characteristics in a reduced parameter form. This parameter transformation simplifies processing by working with fewer, more meaningful values while requiring minimal additional memory storage compared to retaining all original data points.

AI summary
Disclosed is a method of determining a tire performance characteristic of a tire. The method includes obtaining, using a processing system, a performance coefficient of the tire corresponding to performance of the tire during a first time period, wherein the performance coefficient is based on a first plurality of values indicative of a tire parameter over the first time period. The method includes obtaining a second plurality of values indicative of the tire parameter over a second time period, and determining, based on the second plurality of values and the performance coefficient, the tire performance characteristic.
