TWS Earphone Pairing Using Time Difference and RSSI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
TWS earphones often experience inefficient pairing due to serial matching or mismatching with surrounding devices, reducing efficiency and reliability.
Innovation Solution
A method for pairing TWS earphones that involves receiving pairing information, determining the time each earphone enters a working state, and controlling the pairing based on a preset duration threshold and RSSI strength to ensure accurate and reliable pairing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one TWS earphone broadcasts pairing information continuously, then other TWS earphones can perform authentication, but the earphone may be serially matched or mismatched with surrounding earphones, reducing pairing efficiency
Solution Approach 1:
The patent changes the time parameter by recording the working state entry time of each earphone and using time difference comparison to identify the intended pairing partner, resolving the contradiction between continuous broadcasting reliability and pairing efficiency
2Reliability
If TWS earphones use traditional broadcast authentication method, then pairing can be established, but pairing time is extended and efficiency is reduced
Solution Approach 1:
The patent performs preliminary action by recording the working state entry time of each earphone in advance, so that when pairing information is exchanged, the intended partner can be quickly identified through time difference comparison, reducing pairing time while maintaining reliability

AI summary
A method for pairing TWS earphone includes: receiving pairing information sent by second TWS earphones, determining a second time when each of the second TWS earphones enters a working state according to the pairing information, obtaining a first time of the first TWS earphone which enters the working state, controlling the pairing between the first TWS earphone and one of the second TWS earphones according to the first time, the second time and a preset duration threshold.
