U-Shaped Fish Hook Removal Device via Rotational Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing a fish from a hook or lure often require physical contact, which can be undesirable due to the fish's slimy surface or potential for injury from fins, and lack cost-effectiveness and simplicity in design.
Innovation Solution
A U-shaped device with a straight section and gripping handle that applies rotational and gravitational force to dislodge the hook from the fish without direct contact, made from durable, water-resistant materials with a minimal number of parts to reduce costs and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a user manually removes a fish from a hook by touching it with their hands, then the removal process is simple and requires no additional device, but the user is exposed to physical contact with the fish which can cause injury from fins or discomfort from the slimy surface
Solution Approach 1:
The patent introduces a fish removing device as an intermediary tool between the user and the fish. The device includes a U-shaped portion that engages the fishing line and a gripping section that allows the user to hold the device without touching the fish. This mediator enables hook removal while preventing direct physical contact with the fish, thus eliminating exposure to harmful factors like sharp fins and slimy surfaces.
2Object-affected harmful factors
If a device is designed with multiple parts and complex structure to improve fish removal safety, then user protection is enhanced, but manufacturing cost and device complexity increase
Solution Approach 1:
The device is segmented into two main functional portions: a U-shaped portion for engaging the fishing line and a gripping section for user handling. This segmentation allows each part to be optimized for its specific function while keeping the overall structure simple. The U-shaped portion can be formed from a single piece of material, reducing manufacturing steps and costs while still providing effective fish removal capability.
Solution Approach 2:
Different portions of the device have different structural qualities optimized for their specific functions. The U-shaped portion has an open configuration designed to engage the fishing line, while the gripping section has a closed or partially closed configuration designed for comfortable user holding. This local differentiation of structural qualities allows the device to perform multiple functions effectively without requiring a complex overall structure.
3Ease of manufacture
If a device structure is simplified to reduce manufacturing cost, then ease of manufacture is improved, but the ability to prevent physical contact with fish may be compromised
Solution Approach 1:
The device is designed to perform multiple functions with a single unified structure. The U-shaped portion serves both to engage the fishing line and to provide a mechanical advantage for hook removal. The gripping section simultaneously provides user comfort and secure holding. This multi-functionality allows the simplified structure to maintain effective fish removal capability while reducing manufacturing complexity.
Solution Approach 2:
The device incorporates dynamic elements that allow it to adapt during operation. The U-shaped portion can flex and adjust as the fishing line is pulled through, while the gripping section allows natural hand positioning. This dynamic capability ensures the device remains effective across different fish sizes and hook types without requiring a complex adjustable mechanism.

Function Achieved in This Case
Enables easy, low-cost, and safe removal of fish from a hook or lure with minimal user contact, allowing for efficient handling and reduced risk of injury, while being easy to use and manufacture.
Implementation Method 1
The fish is rotated on the fishing line, which applies rotational and gravitational force to the fish thereby dislodging the hook from the fish
Implementation Method 2
The fish is rotated on the fishing line, which applies rotational and gravitational force to the fish thereby dislodging the hook from the fish

AI summary
The present invention relates to a device for removing a fish from a line. The fish removing device has a generally U-shaped portion that extends into an elongated straight section. The straight section bends into a gripping section, which in one embodiment includes a first and second gripping member. After a fish is caught with a hook on a fishing line, the fishing line is caught in the U-shaped portion and slid down to the hook. The fishing line is then positioned horizontally between a first hand and the fish removing device held in a second hand. The fish is rotated on the fishing line, which applies rotational and gravitational force to the fish thereby dislodging the hook from the fish without having the user coming into physical contact with the fish.
