Duplex Bluetooth Tire Pressure Detection With Host-Controlled Locating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire pressure detectors require lengthy one-way data transmission for positioning, leading to power consumption issues and unnecessary re-transmissions, especially when vehicle stops are temporary, causing errors and interruptions in data reception.
Innovation Solution
A duplex Bluetooth transmission system where a transceiver host and tire pressure detectors engage in bidirectional communication, allowing simultaneous starting and stopping of locating and tire condition programs to optimize data transmission and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tire pressure detector transmits locating data continuously for 10 minutes, then the positioning can be completed, but the power consumption increases and time is wasted
Solution Approach 1:
The patent implements periodic action by transmitting locating data only during vehicle stops rather than continuously. The transceiver host receives locating data at periodic intervals when the vehicle is stationary, eliminating unnecessary continuous transmission and reducing power consumption while ensuring positioning is completed when needed.
Solution Approach 2:
The patent applies preliminary action by completing the positioning process during vehicle stops before the vehicle resumes motion. The transceiver host ensures locating data is received and positioning is finalized during idle periods, so no additional transmission is needed when the vehicle starts again, saving both time and energy.
2Reliability
If the tire pressure detector re-transmits locating data after vehicle restart, then positioning accuracy is maintained, but transmission time is wasted
Solution Approach 1:
The patent implements feedback by having the transceiver host check whether positioning has already been completed before initiating re-transmission. The host receives locating data during vehicle stops and maintains positioning information, so when the vehicle restarts, it can determine that no re-transmission is needed, eliminating wasted transmission time while preserving positioning accuracy.
3Device complexity
If the tire pressure detector transmits locating data at fixed intervals, then the positioning process is simple, but data reception may have errors or interruptions
Solution Approach 1:
The patent applies dynamics by making the data transmission adaptive rather than fixed. The transceiver host dynamically determines when to receive locating data based on vehicle operation states (stopped vs. moving). This dynamic approach improves data reception reliability by ensuring transmission occurs only when the vehicle is stationary, while the host manages the process to maintain simplicity.
4Ease of operation
If the tire pressure detector continues transmitting locating data after complete locating, then the system is simple to operate, but energy is wasted
Solution Approach 1:
The patent implements feedback by having the transceiver host monitor the positioning status and control the continuation of locating data transmission. The host determines when positioning is complete and stops receiving further locating data, eliminating energy waste while maintaining ease of operation through automatic control rather than requiring manual intervention.
