Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the auxiliary Bluetooth circuit continuously operates in sniffing mode to monitor packets, then the device can quickly respond to environment changes, but power consumption increases and standby time decreases
Solution Approach 1:
The auxiliary Bluetooth circuit dynamically switches between sniffing mode and relay mode based on packet throughput conditions. When packet throughput exceeds a threshold, it operates in sniffing mode for rapid environment monitoring; when throughput is low, it switches to relay mode to conserve power, thus extending standby time while maintaining responsiveness when needed
Solution Approach 2:
The system changes the operational parameter (mode) of the auxiliary Bluetooth circuit based on the packet throughput parameter. By monitoring packet throughput and comparing it against a threshold, the system adjusts the circuit's operating state to optimize between responsiveness and power consumption
2Use of energy by moving object
If the auxiliary Bluetooth circuit operates in relay mode to forward packets, then power consumption is reduced, but the ability to independently detect environment changes is lost
Solution Approach 1:
The main Bluetooth circuit acts as an intermediary that receives packets from the remote device and forwards them to the auxiliary Bluetooth circuit when the auxiliary is in relay mode. This allows the auxiliary circuit to conserve power while still receiving necessary data through the main circuit, maintaining system functionality without independent detection capability
3Use of energy by moving object
If the main Bluetooth circuit forwards all received packets to the auxiliary Bluetooth circuit, then the auxiliary circuit can operate in low-power relay mode, but data transmission overhead increases
Solution Approach 1:
The main Bluetooth circuit performs partial forwarding of packets to the auxiliary circuit - only forwarding when the auxiliary is in relay mode and only when necessary for maintaining its operational state. This partial action reduces the overall data transmission overhead compared to continuous forwarding, while still enabling the auxiliary circuit to operate in power-saving relay mode

AI summary
A main Bluetooth circuit for use in a multi-member Bluetooth device is disclosed including: a first Bluetooth communication circuit, a first packet parsing circuit, and a first control circuit. In a period during which the auxiliary Bluetooth circuit operates at the sniffing mode, the first control circuit utilizes the first Bluetooth communication circuit to receive packets transmitted from the remote Bluetooth device. In a situation of that a throughput of packets sniffed from the remote Bluetooth device by the auxiliary Bluetooth circuit is lower than a predetermined threshold, the auxiliary Bluetooth circuit switches from the sniffing mode to the relay mode. In a period during which the auxiliary Bluetooth circuit operates at the relay mode, the first control circuit utilizes the first Bluetooth communication circuit to receive the packets transmitted from the remote Bluetooth device and to forward received packets to the auxiliary Bluetooth circuit.
