Engineering Contradiction Analysis
1Productivity
If the second wireless communication device uses larger electromagnetic wave power to communicate with more terminal devices, then the communication coverage and capacity are improved, but the heat generation increases and affects the first wireless communication device
Solution Approach 1:
The patent divides the wireless relay device into two separate wireless communication devices (first and second wireless communication devices), each handling different communication tasks. The second device communicates with terminal devices while the first communicates with the base station, allowing independent thermal management and preventing heat transfer between functions
Solution Approach 2:
The patent applies different electromagnetic wave power levels to different communication functions: the second wireless communication device uses larger power for terminal device communication, while the first uses smaller power for base station communication. This localized power allocation optimizes each function's performance while managing overall heat generation
2Power
If the second wireless communication device generates more heat due to higher power transmission, then the communication performance with terminal devices is improved, but the heat conducts to the first wireless communication device and causes overheating
Solution Approach 1:
The patent segments the wireless communication functions into separate devices within the relay system, allowing the high-power second device to operate independently without thermally affecting the first device, thus maintaining system reliability
Solution Approach 2:
The patent introduces a thermal isolation mechanism as an intermediary between the two wireless communication devices, preventing heat conduction from the high-power second device to the first device, thereby maintaining thermal stability
