Bluetooth Earbud Paging for Faster Single-Earbud Reconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
True wireless stereo (TWS) Bluetooth headsets experience prolonged reconnection times when one earbud is placed back in the charging case without the other, leading to suboptimal user experience due to delayed connectivity with the terminal.
Innovation Solution
A Bluetooth paging method and system that facilitates rapid reconnection of earbuds within a charging case by utilizing a paging mechanism to establish direct communication between earbuds and the terminal, reducing the need for intermediate connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the earbud in the charging case waits for the other earbud to connect first before reconnecting to the terminal, then the connection sequence is maintained, but the reconnection time is prolonged
Solution Approach 1:
The earbud in the charging case performs preliminary actions by attempting to reconnect to the terminal directly without waiting for the other earbud. The system prepares multiple connection paths in advance, allowing the single earbud to independently initiate reconnection to the terminal while the other earbud simultaneously searches for pairing, thereby eliminating sequential waiting time.
Solution Approach 2:
The connection protocol becomes dynamic by allowing flexible connection sequences based on real-time conditions. When only one earbud is present in the charging case, the system dynamically adjusts to allow direct terminal reconnection rather than following a fixed sequential protocol, optimizing reconnection speed while maintaining connection stability.
2Reliability
If the earbud reconnects to the terminal only after connecting to the other earbud expires, then the proper connection protocol is followed, but user experience deteriorates due to long delays
Solution Approach 1:
The system changes connection parameters dynamically based on the number of earbuds detected in the charging case. When one earbud is detected, the reconnection parameters are adjusted to allow direct terminal connection with extended timeout periods, while maintaining the core protocol structure. This parameter adaptation ensures both protocol reliability and improved user experience.
Solution Approach 2:
The connection protocol transitions from a static, rigid sequence to a dynamic adaptive protocol. The system monitors earbud presence and automatically adjusts the reconnection workflow, allowing single earbuds to bypass the mutual pairing requirement and connect directly to the terminal, thereby maintaining protocol integrity while enhancing user experience.
3Stability of the object's composition
If the system requires both earbuds to be present for reconnection, then connection stability is ensured, but reconnection functionality is lost when one earbud is missing
Solution Approach 1:
The reconnection process is segmented into independent pathways: one pathway handles dual-earbud reconnection maintaining stability, while another pathway handles single-earbud reconnection enabling functionality. The system detects which scenario applies and activates the appropriate segment, allowing both connection stability and reconnection functionality to coexist in different operational contexts.
Solution Approach 2:
The charging case system becomes multi-functional by supporting both dual-earbud and single-earbud reconnection scenarios through a unified system architecture. The same charging case infrastructure serves multiple purposes: maintaining stable dual-earbud connections when both are present, and enabling single-earbud reconnection when one is missing, thereby achieving adaptability without sacrificing core stability.

AI summary
This application discloses a Bluetooth reconnection method, and relates to the field of short-range wireless communications technologies. The method includes: When a charging case is closed, a first earbud breaks a Bluetooth connection, where the first earbud stores a Bluetooth address of a terminal and a Bluetooth address of a second earbud. When the charging case is opened, the charging case accommodates only the first earbud, and a first preset condition is met, the first earbud sends a first paging request to the second earbud based on the Bluetooth address of the second earbud. The first preset condition is that the Bluetooth connection includes a Bluetooth connection between the first earbud and the second earbud. In this way, reconnection duration of the first earbud when the charging case is opened can be reduced.
