Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single device is used for both network communication and atmospheric condition detection, then device complexity is reduced, but measurement precision and reliability of atmospheric condition detection deteriorate
Solution Approach 1:
The patent divides the atmospheric condition detection function across multiple devices (first device, second device, third device) rather than concentrating it in a single device. Each device performs specific tasks: the first device transmits RF signals, the second device receives signals for communication, and the third device receives signals specifically for atmospheric condition analysis. This segmentation improves measurement precision while maintaining reasonable device complexity through distributed functionality.
Solution Approach 2:
The patent enables devices to perform multiple functions simultaneously. The first device transmits RF signals for both network communication and atmospheric condition detection. The second and third devices receive signals for both communication and environmental monitoring. This multi-functionality reduces overall system complexity while improving measurement precision through specialized roles.
2Productivity
If millimeter wave frequency band is used for communication, then communication bandwidth and speed are improved, but susceptibility to atmospheric conditions increases
Solution Approach 1:
The patent converts the harmful effect of atmospheric conditions on millimeter wave signals into a beneficial measurement mechanism. By deliberately using the frequency band that is susceptible to atmospheric conditions (30-300 GHz), the system can detect atmospheric composition and environmental parameters through the signal modifications caused by these conditions. The same susceptibility that degrades communication also provides the measurement signal.
Solution Approach 2:
The system uses feedback from the received RF signals to detect atmospheric conditions. The third device analyzes the characteristics of received signals (transmitted by the first device and intended for the second device) to determine atmospheric composition. This feedback mechanism allows the system to continuously monitor atmospheric conditions while maintaining communication functionality.
