Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fishing industry faces inefficiencies in locating fish in marine environments, relying on outdated methods that do not significantly improve the 'last mile' of catching, leading to rising costs and decreased productivity.
Innovation Solution
An unmanned aerial vehicle (UAV) system equipped with sensors and communication components for data collection, analysis, and transmission, enabling the detection, location, and identification of fish and other marine objects, using automated and user-driven object detection, and machine learning for enhanced accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional fishing methods are used to locate fish, then operational simplicity is maintained, but detection precision and fishing efficiency deteriorate
Solution Approach 1:
The patent introduces an unmanned aircraft as an intermediary carrier between the fishing operation and the detection sensors. The aircraft carries multiple sensors (cameras, LIDAR, acoustic sensors) that would be too complex or cumbersome to mount directly on a fishing vessel, thereby achieving high detection precision without proportionally increasing the complexity of the core fishing system
Solution Approach 2:
The unmanned aircraft serves multiple functions: it acts as a mobile platform for various detection sensors, provides aerial navigation to fish locations, and can potentially deploy additional equipment. This multi-functionality consolidates what would otherwise require multiple separate complex systems into a single integrated platform
2Productivity
If unmanned aircraft with multiple sensors are deployed to detect fish, then detection precision and fishing efficiency are improved, but device complexity and operational difficulty increase
Solution Approach 1:
The unmanned aircraft operates autonomously using onboard navigation systems and pre-programmed flight paths. It can independently navigate to coordinates provided by the fishing vessel, perform detection sweeps, and return data without requiring manual piloting or real-time human intervention, thereby maintaining ease of operation while enabling sophisticated multi-sensor detection
Solution Approach 2:
The system uses preliminary actions by having the fishing vessel determine general fish locations using simpler methods first, then the unmanned aircraft performs detailed detection at those predetermined locations. This two-stage approach divides the complex detection task into manageable steps, improving productivity without overwhelming the operator
3Productivity
If traditional fish location methods are used, then fuel consumption is lower, but time consumption and productivity deteriorate
Solution Approach 1:
The unmanned aircraft is deployed selectively only when and where fish are suspected to be present, rather than continuously operating. The vessel uses preliminary detection methods to identify promising areas first, then deploys the aircraft for detailed detection only in those specific zones, achieving high productivity while minimizing unnecessary energy consumption
Data Source
AI summary
The present disclosure describes a system and method for the use of unmanned aircraft systems to detect, locate, and identify objects in, on, or near the water that may provide useful information to people in a different location, such as on a nearby vessel for purposes of ultimately locating fish. The vessel can then take action based on data collected by the unmanned aircraft system, such as move to a new location to catch fish as detected by the unmanned aircraft system.
