Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If machine learning models and ocean circulation models are used to generate optimal ship routes, then route optimization accuracy and emission reduction are improved, but computational resource requirements and system complexity increase
Solution Approach 1:
The system segments the route optimization process into multiple independent models: machine learning models for weather prediction, ocean circulation models for current patterns, and optimization algorithms for route calculation. Each model handles a specific aspect of the problem, allowing parallel processing and reducing overall system complexity while maintaining high accuracy.
Solution Approach 2:
The patent introduces intermediate data structures and processing layers between raw environmental data and final route recommendations. These intermediaries include processed weather patterns, standardized ocean current data, and pre-calculated route options, which simplify the integration of complex models and reduce computational burden.
2Measurement precision
If high-resolution weather and ocean forecasts are produced to improve route accuracy, then route optimization precision is improved, but computational resource consumption increases
Solution Approach 1:
The system applies partial resolution by using high-resolution forecasts only for critical route segments where environmental conditions significantly impact fuel consumption and safety. For less critical segments, lower-resolution data is sufficient, reducing overall computational requirements while maintaining optimization accuracy where it matters most.
Solution Approach 2:
The patent dynamically adjusts the resolution parameter of weather and ocean forecasts based on route characteristics, ship type, and environmental sensitivity. This allows the system to use high-resolution data selectively rather than uniformly across all routes, optimizing the balance between accuracy and computational energy consumption.
3Adaptability or versatility
If real-time route updates are implemented to account for changing weather and ocean conditions, then route adaptability and safety are improved, but data processing time and operational complexity increase
Solution Approach 1:
The system performs preliminary processing by pre-calculating multiple alternative routes and storing them in advance. When real-time environmental data becomes available, the system only needs to select from pre-computed options rather than generating routes from scratch, significantly reducing data processing time while maintaining high adaptability to changing conditions.
Solution Approach 2:
The patent implements dynamic route updating where the system continuously monitors environmental conditions and automatically switches between pre-calculated route options based on current weather and ocean patterns. This dynamic approach allows real-time adaptability without requiring complete re-processing of route data, minimizing time loss while maximizing responsiveness.
