Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-member Bluetooth devices experience signal interruptions and increased power consumption due to the high computing load on the signal relay circuit, leading to poor user experiences, especially in scenarios like Bluetooth earphones where audio interruptions occur.
Innovation Solution
A multi-member Bluetooth device architecture with a main Bluetooth circuit and an auxiliary circuit that allows seamless handover of signal relay duties, where the auxiliary circuit sniffs packets from the remote device and replenishes missing packets, reducing the load on the main circuit and preventing signal interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one member circuit is appointed as the signal relay circuit to act as a data communication bridge, then the multi-member Bluetooth device can maintain a stable Bluetooth connection with the remote device, but the signal relay circuit experiences higher computing load, power consumption, and heat generation
Solution Approach 1:
The patent implements dynamic role switching where member circuits can transition between normal operation mode and signal relay mode. The control circuit monitors the status of the signal relay circuit and dynamically appoints a new signal relay circuit when needed, allowing the system to adaptively distribute the communication bridge function across different member circuits to balance power consumption while maintaining connection stability.
2Duration of action of stationary object
If the signal relay circuit continues operating under high load, then the Bluetooth connection can be maintained, but the computing load and heat generation become unsustainable
Solution Approach 1:
The control circuit is configured to detect status information of the signal relay circuit in advance (such as temperature, power consumption levels) and proactively appoint a new signal relay circuit before the current one becomes unsustainable. This preliminary action prevents overheating and excessive power consumption by transitioning roles before critical thresholds are reached, ensuring continuous operation without harmful heat accumulation.
3Use of energy by moving object
If a new signal relay circuit is appointed to replace the exhausted one, then power consumption can be reduced, but signal interruption occurs during the reestablishment of Bluetooth connection
Solution Approach 1:
The patent ensures continuous data communication by configuring the new signal relay circuit to take over the data communication bridge function immediately upon appointment. The control circuit maintains the Bluetooth connection continuity by seamlessly transferring the signal relay role without interrupting the data flow between the multi-member Bluetooth device and the remote device, thus achieving both power reduction and communication continuity.

AI summary
A multi-member Bluetooth device includes: a main Bluetooth circuit capable of bidirectionally communicating with a remote Bluetooth device through a first Bluetooth communication circuit; and an auxiliary Bluetooth circuit capable of communicating with the main Bluetooth circuit through a data transmission circuit. While the main Bluetooth circuit utilizes the first Bluetooth communication circuit to communicate with the remote Bluetooth device, the auxiliary Bluetooth circuit utilizes a second Bluetooth communication circuit to sniff packets transmitted from the remote Bluetooth device. When detected that the auxiliary Bluetooth circuit has missed packets transmitted from the remote Bluetooth device, the main Bluetooth circuit transmits missing packets of the auxiliary Bluetooth circuit to the auxiliary Bluetooth circuit through the data transmission circuit.
