Hands-Free Fish Dehooking Device Using Rotating Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dehooking methods for fish require manual handling, causing stress and potential injury to both fishermen and fish, especially when releasing immature or undesirable catches, as they necessitate lifting the fish out of the water and often require a second person for assistance.
Innovation Solution
A hands-free dehooking device mounted in a fixed location, featuring a rigid ring on an elongated arm that can be adjusted and rotated, allowing the fishing line to be pulled upward to dislodge the hook without direct contact with the fish, enabling safe and stress-free removal of hooks from fish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling methods are used to remove hooks from fish, then the fisherman can control the dehooking process, but the fish experiences stress and potential injury from being lifted out of water and handled
Solution Approach 1:
The patent introduces a fixed dehooking device with a ring and arm mechanism that acts as an intermediary between the fisherman and the fish. The device allows the fishing line to be pulled through the ring, using the line itself as the intermediary to transmit force and dislodge the hook, eliminating the need for direct manual handling of the fish.
Solution Approach 2:
The fishing line serves a dual function: it both catches the fish and serves as the tool to remove the hook. By pulling the line through the fixed ring, the system uses the existing fishing line to perform the dehooking action, making the fish and line work together in the removal process without requiring additional manual intervention.
2Productivity
If pliers are used to pry the hook out of the fish's mouth, then the hook can be removed, but extra stress is put on the fish and more tissue is torn than necessary
Solution Approach 1:
The fishing line acts as an intermediary tool instead of using pliers. The line is pulled through the fixed ring, and this pulling action on the line transfers force to dislodge the hook from the fish's mouth, avoiding direct contact with the fish's tissue and minimizing damage.
Solution Approach 2:
The patent replaces the mechanical prying action of pliers with a pulling action on the fishing line. Instead of using a separate tool to mechanically lever the hook out, the system uses the tension and pulling force applied to the line itself to remove the hook, resulting in less tissue damage.
3Ease of operation
If the fisherman touches the fish to remove the hook, then direct control over the fish is maintained, but the fish's scales and fins may be damaged reducing its survival rate
Solution Approach 1:
The fixed ring and fishing line serve as intermediaries that allow the fisherman to control and manipulate the fish and hook without direct physical contact. The fisherman pulls the line through the ring, and this indirect manipulation achieves hook removal while preserving the fish's scales and fins.
Solution Approach 2:
The fishing line and fixed device work together to perform the dehooking function without requiring the fisherman's hands to touch the fish. The system uses the line's interaction with the ring to automatically achieve the dehooking action, eliminating harmful contact.
4Ease of operation
If handheld dehooking devices are used, then portability is maintained, but the fisherman must relinquish control of the fishing pole or require a second person for assistance
Solution Approach 1:
The patent combines the dehooking function with the existing fishing pole and line system. The fixed dehooking device is mounted in a location that integrates with the fishing setup, allowing the fisherman to use the same line and pole to both catch and dehook the fish, eliminating the need for separate handheld devices or additional personnel.
Solution Approach 2:
The fishing line serves multiple functions: it catches the fish, transfers it to the fixed device, and removes the hook. The fixed dehooking device provides a universal solution that works with standard fishing equipment, eliminating the need for specialized handheld tools or additional helpers.
5Ease of operation
If the fish is lifted out of water for hook removal, then the hook can be accessed, but the fish experiences unnecessary stress and potential injury
Solution Approach 1:
The fixed ring acts as an intermediary that allows the fishing line to be manipulated while the fish remains in or near the water. The line is pulled through the ring to dislodge the hook, providing access to the fish's mouth area without requiring the fish to be completely lifted out of the water.
Solution Approach 2:
The fixed dehooking device is positioned and oriented to allow the fishing line to be pulled through the ring in a manner that maintains the fish at a consistent water level throughout the dehooking process. This eliminates the need to lift the fish out of water, keeping it in its natural environment and reducing stress.

AI summary
A rotatable, hands free fish dehooking device used for safely removing hooks and lures from a fish's mouth and/or body. The hands free dehooking device has a rigid ring located on an end of an elongated arm that is mounted to a fixed or stationary object, such as a box, boat, or other object that anchors the ring and arm in a fixed position for use. The ring and arm may also be rotatable between stored and in-use positions.
