Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the auxiliary Bluetooth circuit operates in relay mode to forward packets from the main Bluetooth circuit, then power consumption is reduced and standby time is extended, but signal reception quality may degrade and data transmission reliability decreases
Solution Approach 1:
The patent implements dynamic mode switching for the auxiliary Bluetooth circuit, allowing it to transition between relay mode and sniffing mode based on real-time signal quality assessment. This dynamic adjustment enables the system to optimize power consumption while maintaining data transmission reliability by selecting the appropriate operating mode according to current environmental conditions
2Reliability
If the auxiliary Bluetooth circuit operates in sniffing mode to directly receive packets from the remote Bluetooth device, then data transmission reliability is improved, but power consumption increases and standby time decreases
Solution Approach 1:
The system dynamically adjusts the operating mode of the auxiliary Bluetooth circuit based on signal quality indicators. When signal quality is poor, the circuit operates in sniffing mode to ensure reliable data reception. When signal quality is good, it switches to relay mode to reduce power consumption, thus balancing reliability and energy efficiency
3Use of energy by moving object
If the main Bluetooth circuit continuously forwards all received packets to the auxiliary Bluetooth circuit in relay mode, then the auxiliary circuit can operate with lower power consumption, but the main circuit's operational burden increases and overall system performance degrades
Solution Approach 1:
The patent extracts only the necessary packets from the main Bluetooth circuit's received data stream and selectively forwards them to the auxiliary Bluetooth circuit based on packet type and current operating mode. This selective extraction reduces the main circuit's operational burden and improves overall system performance while still enabling the auxiliary circuit to function efficiently in relay mode
4Device complexity
If the multi-member Bluetooth device uses a fixed operation mode configuration, then device complexity is reduced and ease of operation is improved, but adaptability to changing wireless signal environments deteriorates and performance degrades
Solution Approach 1:
The patent implements a dynamic operation mode configuration where the auxiliary Bluetooth circuit can automatically switch between relay mode and sniffing mode based on real-time signal quality assessment. This dynamic adaptability allows the device to respond to changing wireless environments without increasing user-facing complexity, as the mode switching is managed automatically by the control circuit
Solution Approach 2:
The system incorporates feedback mechanisms where the auxiliary Bluetooth circuit continuously monitors signal quality indicators and provides feedback to the control circuit. Based on this feedback, the control circuit automatically adjusts the operating mode, enabling the device to adapt to changing signal environments while maintaining simple operation for the user

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 relay mode, the main Bluetooth circuit receives packets transmitted from the remote Bluetooth device and forwards the received packets to the auxiliary Bluetooth circuit; the auxiliary Bluetooth circuit does not sniff packets issued from the remote Bluetooth device, but will switch to a sniffing mode if a signal reception quality indicator of the auxiliary Bluetooth circuit is superior to a predetermined indicator value. In the period during which the auxiliary Bluetooth circuit operates at the sniffing mode, the auxiliary Bluetooth circuit sniffs packets issued from the remote Bluetooth device and the main Bluetooth circuit receives packets transmitted from the remote Bluetooth device.
