Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-member Bluetooth devices face performance degradation and inconvenience when the data type of packets transmitted from a remote device changes, as the cooperation between main and auxiliary Bluetooth circuits does not adaptively adjust, leading to issues such as increased power consumption, packet loss, and inability to complete operations like firmware updates.
Innovation Solution
A multi-member Bluetooth device with a main Bluetooth circuit and an auxiliary Bluetooth circuit that can dynamically switch between sniffing and relay modes based on packet data type, ensuring effective data transmission and reducing power consumption by optimizing packet handling and forwarding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the auxiliary Bluetooth circuit operates in sniffing mode to monitor packets, then packet reception reliability is improved, but power consumption increases
Solution Approach 1:
The auxiliary Bluetooth circuit dynamically switches between sniffing mode and relay mode based on the detected data type. For multimedia packets with sequence numbers, it operates in sniffing mode to ensure reliable reception through monitoring. For firmware update packets without sequence numbers, it switches to relay mode to reduce power consumption while maintaining functionality through main circuit forwarding.
Solution Approach 2:
The system changes the operational parameters of the auxiliary Bluetooth circuit based on packet characteristics. When sequence numbers are detected in packets, the auxiliary circuit activates full monitoring functionality. When no sequence numbers are present, it transitions to a lower-power relay operation, effectively adapting power consumption to actual reception needs.
2Use of energy by moving object
If the auxiliary Bluetooth circuit operates in relay mode to reduce power consumption, then energy efficiency is improved, but packet reception reliability deteriorates
Solution Approach 1:
The main Bluetooth circuit acts as an intermediary by detecting packet types and determining when relay mode is sufficient. For firmware update packets, the main circuit identifies the absence of sequence numbers and triggers relay mode, where it continues to receive and forward packets to the auxiliary circuit, ensuring reliable delivery without requiring the auxiliary circuit to actively monitor.
Solution Approach 2:
The system uses the inherent characteristics of the data packets themselves (presence or absence of sequence numbers) to automatically determine the appropriate operational mode, eliminating the need for external control or user intervention. The packet structure itself serves as the trigger for mode selection.
3Device complexity
If the Bluetooth circuit configuration remains fixed, then device complexity is reduced, but adaptability to different data types deteriorates
Solution Approach 1:
The Bluetooth circuit configuration transitions from static to dynamic, automatically adapting its operational mode based on real-time packet analysis. The system monitors packet characteristics and switches between sniffing and relay modes, enabling the same hardware to efficiently handle both multimedia streaming and firmware updates without requiring multiple dedicated circuit configurations.

AI summary
A multi-member Bluetooth device for communicating data with a remote Bluetooth device is disclosed including: a main Bluetooth circuit and an auxiliary Bluetooth circuit. In the period during which the auxiliary Bluetooth circuit operates at a sniffing mode, the auxiliary Bluetooth circuit sniffs packets transmitted from the remote Bluetooth device and the main Bluetooth circuit receives packets transmitted from the remote Bluetooth device. But the auxiliary Bluetooth circuit switches from the sniffing mode to a relay mode if the data type of packets transmitted from the remote Bluetooth device changes. In the period during which the auxiliary Bluetooth circuit operates at the relay mode, the main Bluetooth circuit receives packets transmitted from the remote Bluetooth device and forwards the received packets to the auxiliary Bluetooth circuit, and the auxiliary Bluetooth circuit does not sniff packets transmitted from the remote Bluetooth device.
