Pressure Sensitive Foil for Tire Deformation Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Tire Pressure Monitoring Systems (TPMS) do not effectively monitor dynamic behavior of the tire's contact area, such as shape, pressure distribution, and deformation, which are crucial for detecting grip issues and aquaplaning, limiting their ability to improve vehicle safety and comfort.
Innovation Solution
A pressure sensitive foil integrated with a tire pressure sensor module that senses deformations and transmits information to a control device via a wired or wireless interface, allowing for real-time monitoring of tire dynamics and enabling improved safety and comfort features like warning indicators and suspension control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a traditional TPMS is used to monitor tire pressure, then tire pressure information can be reported to the driver, but information related to dynamic behavior of the contact area (shape, pressure distribution, deformation) cannot be obtained
Solution Approach 1:
The patent combines the pressure sensitive foil with the existing TPMS components (sensor housing, battery, transmitter) into an integrated sensor system. The foil is positioned within the tire to contact the road surface, and its signals are processed by the TPMS controller, merging deformation sensing with existing pressure monitoring functionality.
Solution Approach 2:
The pressure sensitive foil serves multiple functions: it detects contact area pressure distribution, measures tire deformation, and provides grip condition information. The existing TPMS infrastructure is utilized to transmit and process this data, making the system multi-functional without requiring completely separate monitoring systems.
2Reliability
If pressure sensitive foil is integrated into the tire to monitor contact area dynamics, then real-time deformation information can be obtained, but the device complexity and implementation difficulty increase
Solution Approach 1:
The pressure sensitive foil is divided into multiple sensing elements or zones that can be independently positioned at specific locations within the tire. This segmentation allows the foil to be integrated into existing tire manufacturing processes at discrete points rather than requiring complete redesign of the entire tire structure.
Solution Approach 2:
The patent uses the existing TPMS sensor housing and mounting structures as intermediaries to facilitate the integration of the pressure sensitive foil. The foil connects to the TPMS electronics through existing signal interfaces, serving as an intermediary layer between the mechanical deformation and the electronic monitoring system.
