Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively provide real-time information about ship waves to small ships, making it difficult for them to avoid the influence of waves generated by larger vessels, which can lead to marine accidents.
Innovation Solution
A ship vicinity information display device that includes a detector to identify nearby ships, a module to generate and display ship wave information, and a processing module to graphically represent these waves on a display unit, along with a risk evaluation and alarm system to alert users of potential hazards, allowing for timely avoidance actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ship wave information is not displayed to small ships, then the display system remains simple, but small ships cannot avoid the influence of ship waves caused by larger vessels
Solution Approach 1:
The system performs preliminary action by detecting the presence of larger ships and calculating their ship wave characteristics before the waves reach small ships. This allows advance warning and preventive action, resolving the contradiction by providing ship wave information proactively rather than reactively.
Solution Approach 2:
The display device acts as an intermediary between the ship wave generation source (larger vessels) and the vulnerable target (small ships). It receives ship wave information, processes it through calculation modules, and presents it in a form that small ship operators can understand and act upon, thereby bridging the information gap.
2Measurement precision
If complex ship wave calculation methods are used, then wave information accuracy improves, but system complexity and computational load increase
Solution Approach 1:
The system changes parameters by selecting and adjusting key variables (ship speed, draft, size) that have the most significant impact on wave generation. By focusing computational resources on these critical parameters rather than attempting to model all physical factors, the system achieves adequate accuracy while maintaining manageable complexity.
Solution Approach 2:
The system applies partial action by implementing calculation methods that provide sufficient accuracy for safety purposes without attempting to achieve complete physical precision. The calculation is designed to deliver the minimum necessary information quality for decision-making, avoiding the excessive complexity of full-scale wave modeling.
