Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If 5G communication is implemented with high frequency band and increased data throughput, then communication performance is improved, but heat generation increases causing overheating
Solution Approach 1:
The patent implements dynamic operation adjustment of antenna modules based on real-time temperature monitoring. The processor continuously monitors temperature and dynamically changes operational states (operating, restricted, or stopped) to balance communication performance with thermal management, preventing overheating while maintaining optimal data transmission rates
Solution Approach 2:
The system changes operational parameters of antenna modules based on temperature conditions. When temperature exceeds thresholds, the processor modifies operational parameters such as power levels, transmission rates, or beamforming intensity to reduce heat generation while maintaining acceptable communication performance
2Reliability
If multiple antenna modules are deployed for mmWave beamforming, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The patent divides the antenna system into multiple independent antenna modules, each capable of independent temperature monitoring and operation control. This segmentation allows selective operation of individual modules based on thermal conditions, managing complexity through modular design while maintaining overall system reliability
Solution Approach 2:
Multiple antenna modules serve universal communication functions with identical capabilities. Each module can independently perform beamforming, transmission, and reception tasks, allowing the system to maintain reliability through redundancy while managing complexity through standardized, interchangeable components
3Duration of action of stationary object
If continuous operation of antenna modules is maintained for smooth communication, then communication continuity is improved, but heat accumulation occurs affecting user comfort
Solution Approach 1:
The system implements periodic temperature monitoring and intermittent operation adjustment. Rather than continuous operation, the processor periodically checks temperature conditions and adjusts antenna module operations accordingly, creating a rhythm of full operation, restricted operation, and shutdown cycles that maintain communication continuity while preventing harmful heat accumulation
Solution Approach 2:
The system takes preliminary anti-action by monitoring temperature trends and adjusting operations before dangerous heat levels are reached. The processor identifies rising temperature patterns and proactively reduces power or shuts down modules before overheating occurs, preventing harmful effects while maintaining communication smoothness
