Duplex Bluetooth TPMS for Faster Tire Sensor Locating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire pressure detectors require significant time and power for one-way data transmission during automatic locating, leading to inefficiencies and potential data loss due to interruptions.
Innovation Solution
A duplex Bluetooth transmission system that allows simultaneous communication between the host and tire pressure detectors for both locating and tire condition detection, reducing transmission time and conserving power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tire pressure detector transmits locating data continuously for 10 minutes, then the locating can be completed, but the power consumption increases significantly
Solution Approach 1:
The system implements periodic action by allowing the tire pressure detector to transmit locating data only during vehicle stop periods when power consumption is acceptable, rather than continuous transmission. The host controls the transmission timing through bidirectional communication, enabling the detector to enter low-power states during vehicle operation while still completing locating when conditions are favorable.
2Reliability
If the tire pressure detector transmits locating data for 10 minutes at fixed time, then the locating can be completed, but the transmission time is excessive
Solution Approach 1:
The system applies dynamics by making the transmission duration adaptive rather than fixed. The host and tire pressure detector negotiate the transmission time dynamically based on signal quality, vehicle state, and locating progress. This allows the system to complete locating faster when conditions are good while still ensuring reliability when conditions are challenging, eliminating the rigid 10-minute transmission requirement.
3Reliability
If the tire pressure detector transmits locating data continuously, then the locating can be maintained, but the system cannot handle interruptions or errors efficiently
Solution Approach 1:
The system implements feedback through bidirectional communication where the host receives locating data from the tire pressure detector and sends control commands back. This feedback mechanism allows the host to monitor transmission quality, detect errors or interruptions, and dynamically adjust the locating strategy by requesting retransmission or modifying transmission parameters, thereby improving error recovery efficiency while maintaining locating continuity.
