Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the auxiliary Bluetooth circuit operates continuously in sniffing mode to monitor packets, then the device can detect signal environment changes and maintain connection reliability, but power consumption increases and standby time reduces

Engineering Contradiction:

Improveconnection reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

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 to monitor signal quality; when throughput is low, it switches to relay mode to reduce power consumption. This dynamic adaptation resolves the contradiction between maintaining connection reliability and reducing power usage.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameter (mode) of the auxiliary Bluetooth circuit based on detected packet throughput. By monitoring packet throughput as a parameter and adjusting the circuit's operating mode accordingly, the system optimizes the balance between reliability monitoring and power consumption.

Inventive Principle:

Principle #35Parameter changes

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 detect signal environment changes is diminished

Engineering Contradiction:

Improvepower consumptionVSAvoidenvironmental adaptation

Core Design Contradiction:

Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The auxiliary Bluetooth circuit dynamically adjusts its operational mode based on real-time packet throughput conditions. When throughput is high, it operates in relay mode for power efficiency; when throughput drops below a threshold, it switches to sniffing mode to detect signal environment changes. This dynamic switching resolves the contradiction between power consumption and environmental adaptability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses packet throughput as feedback to determine the operational mode of the auxiliary Bluetooth circuit. By continuously monitoring throughput and adjusting mode accordingly, the system maintains adaptability to environmental changes while optimizing power consumption based on actual communication conditions.

Inventive Principle:

Solution Approach 1:

The auxiliary Bluetooth circuit performs periodic mode switching between sniffing and relay operations based on packet throughput thresholds. This periodic adaptation allows the system to maintain data transmission efficiency during high-traffic periods while reducing heat generation during low-traffic periods, resolving the contradiction between productivity and temperature management.

Inventive Principle:

Solution Approach 2:

The system changes the operational parameter (transmission activity) of the auxiliary Bluetooth circuit based on detected packet throughput and thermal conditions. By adjusting whether the circuit actively transmits or remains in lower-power relay mode, the system balances data transmission efficiency with heat generation management.

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 while the main Bluetooth circuit receives packets issued from the remote Bluetooth device, and the auxiliary Bluetooth circuit switches from the sniffing mode to a relay mode if the throughput of packets sniffed by the auxiliary Bluetooth circuit is lower than a predetermined threshold. 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 issued from the remote Bluetooth device.
