Engineering Contradiction Analysis
1Reliability
If a conventional radio communication system switches communication paths only after obstacle detection, then the system maintains simplicity in detection mechanisms, but the radio wave communication quality degrades because flying objects cannot be detected before they enter the propagation path
Solution Approach 1:
The system performs preliminary detection of flying objects using a detection unit (such as radar or optical sensor) before they enter the radio wave propagation path. The distance calculation unit computes the distance between the detected object and the propagation path, enabling advance warning. This preliminary action allows the signal control unit to proactively adjust transmission parameters (power, modulation, error correction) before communication quality degradation occurs, rather than reactively switching paths after obstacle detection.
Solution Approach 2:
The system implements a continuous feedback loop where the detection unit monitors the propagation path environment, the distance calculation unit processes position information, and the signal control unit adjusts transmission signal quality indices based on the calculated distance. This feedback mechanism enables real-time adaptation of communication parameters in response to detected flying objects, maintaining communication quality without requiring complex path switching.
2Reliability
If the system proactively detects flying objects and adjusts transmission parameters in advance, then the radio wave communication quality is maintained, but the device complexity increases due to additional detection and calculation units
Solution Approach 1:
The detection unit and distance calculation unit serve multiple functions: they detect flying objects, calculate distances to the propagation path, and provide input for transmission parameter adjustment. This multi-functionality reduces the need for separate dedicated components for each function, thereby limiting the increase in device complexity while achieving proactive communication quality maintenance.
Solution Approach 2:
Instead of adding complex hardware for path switching, the system maintains simplicity by adjusting transmission signal quality indices (power, modulation scheme, error correction level) based on detected object distance. This parameter-based approach allows adaptive communication quality maintenance through software/control logic rather than complex hardware reconfiguration, minimizing device complexity increases.
3Reliability
If the transmission power is increased to compensate for signal degradation, then the communication quality is maintained, but the energy consumption increases
Solution Approach 1:
The signal control unit dynamically adjusts transmission power based on the real-time distance between detected flying objects and the propagation path. When objects are detected at a distance, the system proactively increases power only to the extent needed to maintain quality. When no objects are detected or they are far away, the system returns to normal power levels. This dynamic adjustment prevents continuous high energy consumption while maintaining communication quality only when necessary.
Solution Approach 2:
The system applies partial action by increasing transmission power only partially and only when flying objects are detected in the vicinity of the propagation path. Rather than continuously operating at high power or switching paths, the system applies just enough additional power to compensate for the predicted signal degradation, minimizing energy consumption while maintaining communication quality.
