Rotatable Dehooking Device with Rigid Ring for Fish Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dehooking methods require manual handling of fish, causing stress and potential injury to both the fish and the angler, especially in catch-and-release scenarios or when dealing with small or undesirable fish, as they necessitate lifting the fish out of the water and can damage the fish's scales and fins.
Innovation Solution
A rotatable dehooking device mounted in a fixed location, such as on a boat or storage container, with a rigid ring that allows the fishing line to be pulled upward, dislodging the hook without direct contact, enabling hands-free operation and reducing fish handling stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If hand-held dehooking devices are used, then the fisherman can remove hooks from fish, but the fisherman must touch the fish which can harm the fish's scales and fins
Solution Approach 1:
The patent introduces a fixed dehooking device with a ring as an intermediary tool. The fishing line passes through the ring, allowing the hook to be dislodged by pulling the line upward while the fish remains in the water. This eliminates direct contact between the fisherman's hands and the fish, preventing damage to scales and fins while still enabling effective hook removal.
2Ease of manufacture
If pliers are used to remove hooks, then the hook can be pried out, but the fish must be lifted out of the water which puts extra stress on the fish
Solution Approach 1:
The fixed dehooking device with a ring serves as an intermediary mechanism that allows hook removal without lifting the fish. The ring is positioned so that when the fishing line is pulled upward, the hook catches on the ring and can be dislodged while the fish remains suspended in the water, eliminating the stress of being lifted out of the water.
Solution Approach 2:
The device allows the fishing line itself to perform the dehooking function. By pulling the line upward, the hook is dislodged through the mechanical action of the line passing through the ring, eliminating the need for separate tools like pliers and reducing handling stress.
3Ease of manufacture
If hand-held dehooking devices are used, then the fisherman can remove hooks, but the fisherman must relinquish control of the fishing pole or have a second person present
Solution Approach 1:
The fixed dehooking device with a ring is mounted in a stationary position, allowing the fisherman to guide the fishing line through the ring and remove the hook while maintaining control of the fishing pole with one hand. This eliminates the need to relinquish pole control or have a second person assist.
4Ease of manufacture
If manual handling methods are used, then hooks can be removed from fish, but the probability of injury to the fisherman and/or fish increases
Solution Approach 1:
The fixed dehooking device with a ring acts as a safe intermediary mechanism. The fisherman guides the fishing line through the ring from a safe distance, allowing hook removal without direct contact. This eliminates the risks associated with manual handling, such as needlestick injuries from hooks and damage to the fish, while maintaining effective hook removal capability.

AI summary
A roatable hands free fish dehooking device (1) used for safely removing hooks and lures from a fish's mouth and/or body. The hands free dehooking device has a rigid ring (2) located on an end of an elongated arm (3) that is mounted to a fixed or stationary object (6), such as a box (8), boat (7), or other object that anchors the ring and arm in a fixed position for use. The ring and arm may also be rotatable so the hands free dehooking device may be rotated into a stored position or an operating position.
