Tire Pressure Monitoring Protocol Misinterpretation Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire pressure monitoring systems face challenges in interoperability due to manufacturer-specific protocols, leading to potential misinterpretation of transmission frames by receivers, which can result in incorrect data interpretation and safety issues.
Innovation Solution
The system dynamically adjusts transmitted frames on a frame-by-frame basis to prevent misinterpretation by flipping bits or recalculating checksums, ensuring compatibility with different protocols without altering the data's meaning, thus allowing seamless communication across various receiver configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a manufacturer-specific protocol is used for tire pressure monitoring transmission, then the system can be optimized for specific application needs, but receivers using different protocols cannot interpret the transmissions correctly
Solution Approach 1:
The patent introduces a protocol conversion intermediary that translates between different transmission protocols. The system includes a protocol identifier that detects the incoming protocol type and a converter that transforms the data into the target protocol format, enabling seamless communication between receivers using different protocols without losing data integrity
Solution Approach 2:
The transmitter is designed with multi-functionality to support multiple transmission protocols simultaneously. By incorporating protocol detection and dynamic conversion capabilities, a single device can adapt to various receiver protocol requirements, making the system universally compatible across different manufacturers' receivers
2Adaptability or versatility
If the system dynamically adjusts transmitted frames to prevent misinterpretation, then protocol compatibility is improved, but the processing complexity increases
Solution Approach 1:
The system performs preliminary protocol identification and conversion preparation before actual data transmission. By detecting the required protocol format in advance and pre-processing the frame structure, the system avoids complex real-time adjustments during transmission, reducing processing complexity while maintaining compatibility
Solution Approach 2:
The frame processing is divided into distinct functional segments: protocol identification, checksum calculation, data field adjustment, and transmission. This segmentation allows each component to handle specific tasks independently, simplifying the overall complexity while achieving comprehensive protocol adaptation

AI summary
A determination is made as to whether a frame to be transmitted according to a first protocol is susceptible to being incorrectly interpreted by a receiver in a vehicle as being transmitted according to a second protocol. When the frame is determined to be susceptible to an incorrect interpretation, an internal value of the frame is adjusted, and the adjustment is effective to prevent an incorrect interpretation of the frame being transmitted from the tire pressure monitor to the receiver. The adjusted frame can then be transmitted.
