Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire pressure measurement systems consume excessive power due to bidirectional communication requirements and need for additional receivers, which increase costs and reduce battery lifespan.
Innovation Solution
Incorporating intelligence into the pressure sensing unit to adjust data transmission rates based on pressure variations, allowing for unidirectional communication and reducing power consumption by switching between low and high repetition rates depending on detected pressure changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bidirectional communication is used for tire pressure measurement systems, then identification and communication capabilities are improved, but power consumption and device complexity increase
Solution Approach 1:
The patent extracts the communication intelligence from the sensing unit and places it in the receiver. The sensing unit only transmits data unidirectionally, while the receiver handles identification, recognition, and communication logic. This eliminates the need for a receiver in the sensing unit, reducing power consumption and device complexity while maintaining full communication capability.
2Reliability
If bidirectional communication is implemented with receivers in sensing units, then communication reliability is improved, but costs and device complexity increase
Solution Approach 1:
The receiver functionality is extracted from the sensing unit and consolidated into a central receiver device. The sensing unit becomes a simple transmitter, reducing its complexity. The central receiver handles all communication protocols, identification, and data processing, maintaining reliability while reducing overall system complexity and cost.
3Productivity
If data transmission repetition rate is increased for pressure monitoring, then detection capability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic transmission rate adjustment based on pressure conditions. During normal operation, data is transmitted at a low repetition rate to conserve power. When pressure variations are detected, the transmission rate automatically increases to provide detailed monitoring. This dynamic adjustment optimizes both detection capability and power consumption.
Data Source
AI summary
In a method for transmitting data, the step of transmitting the data representing a measured pressure or pressure variation is repeated with a first repetition rate if no pressure variation has been detected or repeated with a second repetition rate if a specific pressure variation has been detected. The second repetition rate is higher than the first repetition rate. The different repetition frequencies can be used in a method for determining a tire position in a tire pressure measurement system to switch between a first mode of operation and a second mode of operation. The method for determining a tire position evaluates the repetition rate between the received data packets of transmitted data and extracts a pressure variation out of the received data packets.
