Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional monitoring methods are used for floating waste, then monitoring capability is limited, but system complexity and cost increase
Solution Approach 1:
The patent uses satellite images as a copy or representation of the actual marine waste conditions. Instead of deploying complex monitoring equipment in the ocean, the system captures images from satellites and processes them to identify waste locations, quantities, and types. This copying approach enables comprehensive monitoring capability while avoiding the complexity and cost of in-situ monitoring systems.
2Productivity
If heavy equipment is used to collect floating waste in distant sea, then collection capability improves, but operation difficulty and cost increase
Solution Approach 1:
The system performs preliminary actions by using satellite images to identify and locate floating waste before collection operations begin. The waste information processing unit analyzes satellite data to determine precise locations and quantities of waste, allowing collection vessels to navigate directly to waste sites with appropriate equipment already prepared. This preliminary identification eliminates the need for extensive sea searches and reduces operation difficulty.
Solution Approach 2:
The patent introduces an information processing system as an intermediary between satellite observation and waste collection. The waste information processing unit acts as a mediator that translates satellite images into actionable collection information, including location coordinates, waste quantity estimates, and collection priority assessments. This intermediary layer enables efficient coordination between monitoring and collection operations without requiring direct human intervention in harsh marine environments.
3Loss of time
If waste collection is delayed, then response time decreases, but waste drift and environmental damage increase
Solution Approach 1:
The system implements feedback mechanisms where satellite images continuously monitor waste locations and the waste information processing unit updates collection priorities based on changing conditions. When waste is detected or its location changes, the system immediately processes this information and adjusts collection schedules accordingly. This feedback loop ensures rapid response to waste movements, minimizing drift and environmental damage by keeping collection operations synchronized with actual waste locations.
