Engineering Contradiction Analysis
1Productivity
If mmWave bands are used for 5G communication, then data rate is improved, but overheating occurs
Solution Approach 1:
The patent dynamically adjusts communication parameters (bandwidth, MIMO rank) based on real-time temperature monitoring. When overheating is detected, the system reduces these parameters to lower power consumption and heat generation, while maintaining communication functionality. This dynamic adaptation resolves the contradiction between achieving high data rates and preventing overheating.
Solution Approach 2:
The system changes operational parameters (bandwidth, MIMO rank, power levels) in response to temperature conditions. By modifying these parameters, the system can operate at high performance levels when cool and reduce performance to manage heat when necessary, thus resolving the contradiction between data rate and temperature control.
2Temperature
If bandwidth and MIMO rank count are reduced to control overheating, then temperature is improved, but communication performance deteriorates
Solution Approach 1:
The system dynamically adjusts communication parameters based on real-time temperature monitoring. When overheating is detected, the system reduces these parameters to lower power consumption and heat generation, while maintaining communication functionality. This dynamic adaptation resolves the contradiction between achieving high data rates and preventing overheating.
Solution Approach 2:
The patent implements a feedback mechanism where temperature sensors continuously monitor device temperature and provide information to the communication controller. Based on this feedback, the system adjusts bandwidth and MIMO rank settings to prevent overheating while maintaining acceptable communication performance. The feedback loop ensures temperature control without completely sacrificing performance.
