Hub Wheel Unit Centralizes Tire Pressure Data Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire pressure monitoring systems in vehicles require each wheel unit to transmit signals independently, leading to excessive energy consumption and reduced battery life, particularly when alerting drivers to tire pressure issues before the vehicle is started, which can compromise safety.
Innovation Solution
Implementing a hub wheel unit that temporarily centralizes communication, allowing bidirectional data exchange using HF or UHF radio waves, grouping signals from peripheral wheel units and relaying them to a remote monitoring device, thereby reducing energy expenditure and improving alert responsiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each wheel unit transmits signals independently to remote monitoring devices, then communication reliability is improved, but energy consumption increases significantly
Solution Approach 1:
The patent introduces a hub wheel unit as an intermediary that collects data from peripheral wheel units and transmits consolidated information to remote monitoring devices. This mediator approach reduces the number of independent transmission channels, lowering overall energy consumption while maintaining communication reliability through centralized data aggregation and relay.
Solution Approach 2:
The patent merges multiple independent transmission operations into a single centralized transmission process. Instead of each wheel unit transmitting separately, the hub wheel unit consolidates data from all peripheral units and performs unified transmission, significantly reducing redundant energy expenditure while preserving data integrity.
2Reliability
If each wheel unit transmits with high power to ensure reception, then signal reception reliability is improved, but battery life is reduced
Solution Approach 1:
The hub wheel unit acts as a mediator that receives signals from peripheral wheel units at lower power levels and then transmits consolidated data to remote devices. This intermediary structure eliminates the need for each peripheral unit to transmit at high power, thereby extending battery life while maintaining signal reception reliability through the hub's centralized transmission.
Solution Approach 2:
The patent applies partial action by having only the hub wheel unit perform high-power transmission to remote devices, while peripheral wheel units transmit at lower power levels to the hub. This selective application of transmission power reduces overall energy consumption while ensuring reliable signal reception at the remote monitoring devices through the hub's amplified transmission.
3Use of energy by moving object
If wheel units transmit alerts at predetermined periodicity, then energy consumption is controlled, but alert responsiveness is reduced
Solution Approach 1:
The patent implements feedback mechanisms where the hub wheel unit and peripheral wheel units can trigger immediate transmissions when critical events occur, such as tire pressure anomalies. This feedback-driven approach allows the system to maintain low energy consumption during normal operation while enabling rapid alert responsiveness when needed, eliminating the delay inherent in fixed periodic transmission schedules.
Solution Approach 2:
The transmission system transitions from static predetermined periodicity to dynamic event-driven transmission. The hub and peripheral wheel units can adjust transmission timing based on real-time conditions, allowing immediate alert transmission when critical events occur while maintaining energy efficiency during normal operating conditions. This dynamic approach resolves the contradiction between energy control and alert responsiveness.

AI summary
A method for communication of a plurality of wheel units with one another and with a device for remotely monitoring and/or controlling the wheel units, the wheel units measuring a pressure value of a wheel of a motor vehicle as parameter(s). The units are identified beforehand and each wheel unit may identify the other wheel units, the communication taking place in accordance with a communication standard allowing a bidirectional data exchange. A hub wheel unit storing the pressure values measured by each of the wheel units is selected at least temporarily, the other units being peripheral. The hub unit sends a signaling frame in the direction of the peripheral units, received in a peripheral unit through scanning. The pressure values are communicated between the wheel units and a device solely via the hub unit.
