Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If channels are shut down periodically to save energy, then energy consumption is reduced, but wireless connection quality deteriorates
Solution Approach 1:
The patent implements dynamic energy-saving control by continuously monitoring antenna beam forming information and adjusting channel operations in real-time based on actual service conditions, rather than using fixed periodic shutdown schedules. This allows the system to adapt channel states dynamically to maintain connection quality while saving energy.
Solution Approach 2:
The system uses antenna beam forming information as feedback to determine channel operation states. By monitoring beam forming data and using it to adjust channel shutdown decisions, the system creates a closed-loop control mechanism that prevents connection quality deterioration while achieving energy savings.
2Use of energy by moving object
If time slots are shut down to save energy, then energy consumption is reduced, but service delay increases
Solution Approach 1:
The patent applies dynamic control to channel operations based on real-time antenna beam forming information, avoiding fixed time slot shutdowns. This allows the system to respond flexibly to service demands and prevent unnecessary delays while maintaining energy-saving benefits.
Solution Approach 2:
The system performs preliminary assessment of antenna beam forming information before making channel shutdown decisions. By evaluating beam forming data in advance, the system can predict service requirements and avoid shutdowns that would cause delays, while still enabling energy-saving shutdowns when appropriate.
3Use of energy by moving object
If uniform coarse optimization is applied to all channels, then energy consumption is reduced, but control precision deteriorates
Solution Approach 1:
The patent implements local quality control by applying different energy-saving strategies to different channels based on their specific antenna beam forming characteristics. Rather than uniform coarse optimization, each channel is controlled according to its local conditions, achieving both energy savings and precise control.
Solution Approach 2:
The system changes control parameters dynamically based on antenna beam forming information. By adjusting channel operation states according to varying beam forming parameters, the system achieves precise control adapted to current conditions while maintaining energy-saving effectiveness.
