Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the smart wearable device transmits at maximum power as requested by Bluetooth devices, then the communication reliability is improved, but the power consumption increases and battery life deteriorates
Solution Approach 1:
The patent implements dynamic power adjustment by monitoring communication scenarios and signal quality in real-time, then selecting appropriate power levels from multiple preset options. The system transitions from static maximum power transmission to dynamic adaptive power control, adjusting transmission power based on actual communication needs and environmental conditions.
Solution Approach 2:
The patent changes the power transmission parameter from a fixed maximum value to multiple preset power levels. By introducing variable power parameters selected based on communication scenarios and signal quality metrics, the system optimizes the balance between communication reliability and power consumption.
2Reliability
If Bluetooth devices request maximum power transmission, then the signal quality is improved, but the battery life of wearable devices deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the system monitors communication scenarios and signal quality, then uses this information to adjust power transmission levels. The feedback loop continuously evaluates communication needs and adjusts power accordingly, ensuring optimal signal quality while minimizing unnecessary power consumption that would drain the battery.
Solution Approach 2:
The system dynamically adjusts transmission power based on real-time monitoring of communication scenarios and signal quality, rather than maintaining static maximum power. This dynamic adaptation extends battery life by reducing power consumption during periods when maximum power is not required for adequate communication.
3Speed
If the smart wearable device uses high power transmission, then the communication distance is improved, but the audio lag increases
Solution Approach 1:
The patent applies dynamic power adjustment to optimize the balance between communication distance and audio timing. By monitoring communication scenarios and adjusting power levels in real-time, the system maintains adequate transmission distance while avoiding excessive power usage that causes audio buffer delays and lag.
Solution Approach 2:
The system changes the transmission power parameter from fixed maximum to variable preset levels, selecting appropriate power based on communication distance requirements and audio timing constraints. This parameter optimization reduces audio lag by preventing unnecessary high-power transmissions that create buffer delays.
