UWB Tyre Sensor Integration for Sensing, Communication, and Ranging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tyre monitoring systems require multiple components to perform sensing, communication, and localisation functions, leading to increased complexity and cost.
Innovation Solution
A tyre monitoring sensor utilizing an ultra-wideband (UWB) device that operates in three modes: sensing to determine tyre properties, communication to transmit data to a control unit, and ranging to localise the sensor relative to a controller node.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate components are used to perform sensing, communication, and localisation functions, then each function can be performed reliably, but the device complexity and bill of materials increase
Solution Approach 1:
The patent combines sensing, communication, and localisation functions into a single integrated UWB device mounted on the tyre. The UWB device performs all three functions using a unified hardware platform, eliminating the need for separate components and reducing overall system complexity while maintaining functional reliability through multi-mode operation
Solution Approach 2:
The UWB device is designed with multi-functionality to perform sensing (tyre property determination), communication (data transmission to control unit), and localisation (ranging relative to controller nodes) within a single device. This universal approach allows one component to fulfill multiple roles that traditionally required separate dedicated components
2Reliability
If multiple separate components are used for sensing, communication, and localisation, then each function can be optimised independently, but the overall cost of the system increases
Solution Approach 1:
By merging sensing, communication, and localisation into a single UWB device, the patent reduces the bill of materials and overall system cost. The integrated approach eliminates redundant components and reduces assembly complexity, making the system more cost-effective while maintaining all required functional capabilities
Solution Approach 2:
The multi-functional UWB device reduces manufacturing cost by using a single platform for multiple functions. Instead of procuring and assembling separate components for sensing, communication, and localisation, the system uses one universal device that performs all three functions, thereby reducing both component costs and assembly costs
