Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only position information of the interference source is considered for estimating the interference area, then the estimation process is simple, but the estimation accuracy is insufficient
Solution Approach 1:
The patent combines multiple types of information (position information of interference source, topographic information of the seabed, and sound speed distribution information) into a comprehensive interference area estimation model. This merging of multiple data sources resolves the contradiction by achieving high estimation accuracy through integrated analysis while managing complexity through systematic processing of each information type.
Solution Approach 2:
The patent utilizes changes in sound speed parameters at different water depths and locations, along with topographic parameter variations, to accurately model interference wave propagation. By incorporating these parameter changes rather than assuming uniform conditions, the system achieves precise interference area estimation that adapts to actual underwater environmental variations.
2Reliability
If acoustic wave communication is performed under water, then communication capability in deep water is achieved, but communication quality is degraded by interference waves from interference sources
Solution Approach 1:
The patent applies preliminary anti-action by estimating the interference area before communication occurs and using this information to prevent interference wave impact. The system proactively identifies regions where interference waves may propagate and communicates this information to the communication apparatus, enabling it to take preventive measures such as selecting alternative frequencies or adjusting transmission parameters before interference degrades communication quality.
Solution Approach 2:
The patent implements feedback by continuously monitoring the underwater environment, estimating interference areas based on current conditions (interference source position, topography, sound speed distribution), and providing real-time interference area information to the communication system. This feedback loop enables dynamic adjustment of communication parameters to maintain reliability despite the presence of interference sources.

AI summary
In order to enable more accurate estimation of an interference area for communication using an acoustic wave under water, an interference area information output apparatus, which is connected to a base station performing wireless communication using an acoustic wave with a wireless communication apparatus being present under water, estimates an interference area being a range where an interference wave possibly interferes with the wireless communication, based on position information relating to an interference source emitting the interference wave being an acoustic wave possibly interfering with the wireless communication, topographic information relating to a periphery of the interference source, and sound speed distribution indicating a sound speed at each location under water in the periphery of the interference source, and outputs interference area information including information relating to the interference area.
