Fishhook Remover With Retractable Grabber And Alignment Needle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Anglers face difficulties and risks when removing fishhooks from catches, as existing methods can cause damage to the fish and are inefficient, particularly in securely dehooking without causing harm to the fish's mouth, gill, or organs.
Innovation Solution
A fishhook remover with a hollow shaft, retractable grabber, and fishhook alignment needle that securely engages and retains the fishhook, allowing for easy removal by actuating the grabber between extended and retracted positions, minimizing damage to the fish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional dehooking methods are used, then the fishhook can be removed from the catch, but damage is caused to the fish's lip, gill, and organs
Solution Approach 1:
The patent introduces a fishhook remover as an intermediary tool between the angler and the fish. The device includes a hollow shaft with a grabber mechanism that securely grasps the fishhook, and a needle that threads through the fishhook's eye to control its orientation. This intermediary tool allows the fishhook to be removed without direct manual manipulation that could damage the fish's sensitive tissues.
Solution Approach 2:
The grabber mechanism extracts the fishhook from the fish's body by securely grasping it. The needle extracts the need for complex manipulation by simply threading through the eye to establish proper orientation. This extraction approach removes the harmful element (fishhook) without requiring the angler to directly handle the fish's vulnerable areas.
2Productivity
If manual dehooking techniques are used, then the fishhook can be removed, but the process is time-consuming and inefficient
Solution Approach 1:
The needle is inserted through the fishhook's eye in advance to establish the correct orientation before the grabber engages the fishhook. This preliminary action ensures that when the grabber secures the fishhook, it is already positioned for optimal removal, eliminating the need for time-consuming adjustments during the extraction process.
Solution Approach 2:
The device incorporates movable components including a sliding grabber mechanism and a retractable needle that can extend and retract along the hollow shaft. This dynamic design allows for quick engagement and disengagement of the fishhook, significantly reducing the time required for dehooking compared to static manual techniques.
3Reliability
If a simple grabber mechanism is used, then the device is easy to operate, but it cannot securely retain the fishhook for safe removal
Solution Approach 1:
The patent merges multiple functions into a single integrated device: the hollow shaft provides structural support and guides the needle, while the grabber mechanism attaches to the shaft to secure the fishhook. The needle and grabber work together as a coordinated system within the hollow shaft, achieving reliable fishhook retention without requiring multiple separate tools or overly complex mechanisms.
Solution Approach 2:
The needle is nested within the hollow shaft, and the grabber mechanism is nested within the hollow shaft as well. This nested configuration allows the device to maintain a compact form while incorporating multiple functional components. The grabber can extend from the hollow shaft to engage the fishhook, then retract back into the shaft, providing secure retention without excessive external complexity.

AI summary
A fishhook remover for dehooking a fishhook from a catch is provided. The fishhook remover includes a hollow shaft having a first end, a second end, and a bore extending from a handle provided at the first end to an opening provided at the second end. The fishhook remover includes a retractable grabber within the bore of the hollow shaft and extending out from the second end for grabbing/retaining the fishhook, and an actuating member slidably engaging the hollow shaft between the first and second ends for actuating the grabber between an extended position and a retracted position. The fishhook remover includes a fishhook alignment needle for engaging the eye of the fishhook. The needle can be in proximity to the second end of the hollow shaft and configured to orient the fishhook in a position where it can be engaged by the grabber.
