Tire Pressure Warning System Puncture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire pressure monitoring systems (TPMS) cannot differentiate between tire pressure drops due to punctures and natural pressure drops, leading users to incorrectly assume natural drops and potentially ignore serious tire damage.
Innovation Solution
A tire internal pressure warning system that includes a TPMS sensor transmitter and receiver, and an information terminal device, which uses wireless communication and a control unit to determine whether pressure drops are due to punctures or natural changes by analyzing internal pressure data and displaying appropriate warnings on a display screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional TPMS only monitors tire pressure decrease, then the system is simple and easy to operate, but the user cannot distinguish between puncture and natural pressure drop leading to incorrect judgment
Solution Approach 1:
The patent segments the pressure monitoring function into two distinct analysis modes: natural pressure drop detection and puncture detection. By dividing the monitoring task into separate evaluation criteria (gradual decline pattern vs. sudden drop pattern), the system provides differentiated information without requiring a completely new system architecture.
Solution Approach 2:
The system dynamically adjusts its analysis based on the rate and pattern of pressure change. It transitions between monitoring modes depending on whether the pressure decrease is gradual (natural) or sudden (puncture), allowing the system to adapt its response to different failure scenarios without manual intervention.
2Measurement precision
If TPMS provides only basic pressure monitoring, then the device complexity is low, but the measurement precision for diagnosing tire conditions is insufficient
Solution Approach 1:
The system implements feedback by continuously monitoring pressure changes and providing diagnostic information back to the user. The control unit analyzes the pressure data pattern and feeds back the diagnosis (natural drop or puncture) to the display, enabling precise condition assessment through systematic data evaluation rather than simple threshold alerts.
Solution Approach 2:
The patent utilizes changes in pressure parameters over time to distinguish between different failure modes. By analyzing the rate of pressure change, the pattern of decline, and the magnitude of drops, the system extracts diagnostic information from existing pressure measurements without requiring additional sensors or complex hardware modifications.
3Reliability
If the system only warns of pressure drop without differentiation, then the ease of operation is high, but the reliability of user decision-making is reduced
Solution Approach 1:
The system performs self-diagnosis by automatically analyzing pressure patterns and determining the cause of pressure loss. The control unit independently evaluates whether the condition represents a puncture or natural drop, providing ready-to-use diagnostic information that eliminates the need for user analysis while maintaining simple operation through automated decision support.

AI summary
The present invention provides a tire internal pressure warning system, comprising: an internal pressure data acquisition apparatus for obtaining data of internal pressure of each tire 5 of a vehicle 6 (a TPMS sensor transmitter 1 and a TPMS receiver 2); and an information terminal device 3 for determining whether there is a puncture-based failure or a failure resulting from a natural pressure drop, based on a change in the internal pressure of each tire received from the TPMS receiver 2, and displaying a warning in accordance with the failure condition.
