UAV Fishing Line Release Mechanism to Prevent Sea Pull-Down
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles (UAVs) used for fishing are prone to being pulled into the sea when a fish is hooked, limiting their effectiveness and safety in pole cast fishing.
Innovation Solution
A fishing system incorporating an unmanned aerial vehicle with a fishing line fixing portion that includes a first and second fixing portion, allowing independent release of the fishing line from the UAV, enabling the UAV to avoid being pulled into the sea by detecting fish hooking and releasing the fixing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the UAV carries the fishing line and artificial bait for pole cast fishing, then the fishing range is extended beyond land-based pole cast limits, but the UAV is pulled into the sea when a fish is hooked
Solution Approach 1:
The fishing line fixing portion is divided into a first fixing portion and a second fixing portion that can be independently released. When a fish is hooked, only the first fixing portion is released to drop the artificial bait, while the second fixing portion remains attached to the UAV to prevent it from being pulled into the sea.
Solution Approach 2:
The harmful effect of the fishing line pulling the UAV into the sea is extracted and isolated by separating the fixing portions. The first fixing portion is extracted and independently controllable, allowing it to be released when a fish is hooked without affecting the second fixing portion that maintains UAV safety.
2Measurement precision
If the UAV is equipped with imaging device and fish tracking capability, then the bait can be precisely dropped on fish location, but the system complexity increases
Solution Approach 1:
The imaging device serves multiple functions: it captures images for fish detection, tracks fish movement, determines bait dropping locations, and monitors whether a fish is hooked. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The imaging device and image processing unit work together to automatically detect fish, track them, and determine optimal bait dropping positions without requiring external intervention. The system processes images and makes decisions autonomously based on the captured visual data.

AI summary
A fishing system includes an unmanned aerial vehicle and a fishing line fixing portion placed on a main body of the unmanned aerial vehicle, the fishing line fixing portion including a first fixing portion for fixing a fishing line and a second fixing portion detachably connected to the first fixing portion. The unmanned aerial vehicle includes an imaging device, a fish school tracking processing unit configured to identify a fish in imaging data captured by the imaging device and control the unmanned aerial vehicle to track the fish. A connection between the first fixing portion and the second fixing portion is released when the fish is hooked on an artificial bait attached to a first end of the fishing line.
