Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If AtoN facilities are installed and modified in real sea areas based on experiential data and repeated installments, then the disposition can be adjusted according to actual shipping risks, but the operational cost and service burden increase significantly
Solution Approach 1:
The system performs preliminary disposition planning and evaluation in a virtual environment before actual installation. Multiple disposition schemes can be simulated and compared in advance, allowing the optimal arrangement to be determined prior to real-world deployment, thus avoiding repeated installations and modifications in actual sea areas.
Solution Approach 2:
The system creates a virtual copy of the real sea area including geographical features, shipping routes, and traffic patterns. This virtual model allows for realistic simulation and evaluation of AtoN facility dispositions without the costs and complexities of actual installation and modification operations.
2Ease of manufacture
If AtoN facilities are arranged using conventional methods (equal intervals for straight courses, 3-4 facilities at apex for curved courses), then the installation process is simplified, but the effectiveness for maximizing installment effects is insufficient
Solution Approach 1:
The system evaluates multiple disposition parameters including facility position, type, quantity, and arrangement patterns. By simulating different parameter combinations and their effects on shipping safety and traffic flow, the system identifies optimal dispositions that go beyond conventional fixed patterns, achieving both effectiveness and adaptability.
Solution Approach 2:
The system provides dynamic evaluation and optimization of AtoN dispositions based on varying shipping risks, seasonal patterns, and changing traffic conditions. Rather than static conventional arrangements, the system can adapt disposition recommendations to match actual operational requirements and risk profiles.
3Adaptability or versatility
If frequent modifications are made to AtoN facilities due to changing shipping risks, then the disposition can adapt to new risks, but the time and cost burden increases
Solution Approach 1:
The system enables preliminary evaluation of multiple disposition schemes for different risk scenarios before actual installation. By planning for various potential risks in advance through simulation, the system reduces the need for frequent post-installation modifications, saving time and resources.
Solution Approach 2:
The system provides feedback mechanisms that evaluate the effectiveness of AtoN dispositions and identify areas for improvement. This continuous evaluation allows for targeted, data-driven modifications rather than frequent arbitrary changes, reducing overall modification frequency while maintaining adaptability to changing conditions.

AI summary
Disclosed is an AtoN simulator system, allowing an AtoN facility to be freely disposed in advance in a virtual space reproduced in the same condition with a real sea area, before installing an AtoN at the real sea area, by utilizing a simulation technology. For disposition and management of an AtoN, it is practicable to dispose and design in advance the AtoN through a simulator before installing and modifying the AtoN with high difficulty and costs in a real sea area, reducing a term and costs for service. Moreover, preliminarily confirming the pertinence to disposition and design of AtoN to be installed in a real sea area, by way of the simulation, contributes to prevent marine casualties from being caused due to incongruence of the AtoN.
