Tire Management Apparatus Using Temperature Load Speed Accumulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire management systems fail to accurately identify the usage status of pneumatic tires based on internal tire temperature, despite temperature being measured alongside pressure.
Innovation Solution
A tire management method and apparatus that detects temperature inside the tire air chamber, converts it into multiplication values related to load and speed, and accumulates these values to determine the tire's usage status, using a temperature detector, converter, and accumulator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature inside the tire is measured using a TPMS, then temperature data is obtained, but the usage status of the tire cannot be accurately identified
Solution Approach 1:
The patent transforms the temperature parameter by converting it into multiplication values (temperature × load × speed or temperature × load² × speed) and accumulating these values over time. This parameter transformation enables the temperature data to reflect actual tire usage intensity and duration, accurately identifying tire usage status and remaining lifespan.
2Reliability
If conventional tire management methods are used, then tire life is predicted based on wear amount and durability, but the methods do not utilize temperature data for accurate usage status identification
Solution Approach 1:
The patent makes the existing TPMS temperature measurement system multi-functional by utilizing its temperature data not only for basic temperature monitoring but also for calculating multiplication values that indicate tire usage status. This approach enables accurate tire life prediction without adding separate measurement devices, thereby improving reliability while avoiding increased device complexity.
