Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If on-site investigation is conducted to determine radio interference, then accurate determination can be made, but it takes too much time
Solution Approach 1:
The patent creates a virtual copy of the radio wave environment by generating synthetic radio waves that replicate actual propagation conditions. This virtual model allows investigators to reproduce and analyze interference scenarios without visiting the actual site, maintaining determination accuracy while eliminating time-consuming on-site travel and manual measurements
Solution Approach 2:
The patent replaces manual on-site investigation methods with automated computer-based simulation. The system uses algorithms to generate and analyze synthetic radio wave data, substituting physical presence and manual measurement tools with computational analysis that provides equivalent or superior determination capability without time loss
2Reliability
If general service quality monitoring is performed, then degradation can be detected, but the cause cannot be quickly identified
Solution Approach 1:
The patent implements a feedback mechanism where the computer generates synthetic radio wave data based on actual propagation conditions, compares this with measured data, and iteratively adjusts the virtual model. This feedback loop enables the system to not only detect service quality degradation but also rapidly identify its cause by matching patterns between synthetic and actual interference scenarios
Solution Approach 2:
The system performs preliminary analysis by pre-generating synthetic radio wave models that represent various interference conditions. When service quality degradation is detected, the system can immediately compare against these pre-prepared models to quickly identify the cause, rather than starting investigation from scratch

AI summary
An interference information outputting device receives signal information that is information relating to quality of a reception signal being the wireless signal received by a wireless reception means, estimates whether radio interference occurs at a location position at which the wireless reception means is located, based on an estimation condition being a condition that is fulfilled when radio interference occurs, outputs interference information being information relating to radio interference, and further calculates a reliability degree indicating a degree of accuracy of the estimation when a result of the estimation is affirmative. The estimation condition includes a condition relating to the signal information. The interference information includes information relating to the location position and information relating to the result of the estimation, and includes information relating to the reliability degree when the result of the estimation is affirmative.
