Fishhook Remover Rack and Pinion Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishhook removal devices fail to efficiently rotate the hook within a fish's confined organs, such as the stomach, to reverse the barb without re-engaging it into the tissue or requiring manual insertion into the fish's mouth.
Innovation Solution
A device with a tubular housing, extending bar, and removal tool featuring a rack and pinion mechanism that allows the hook holder to rotate up to 200 degrees in a plane parallel to the shaft, enabling safe extraction of fish hooks without re-engaging the barb, using a trigger-activated linear motion to convert into rotational force for hook reversal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional forceps or pliers are used to grip the hook, then the fisherman can manipulate the hook, but the device cannot rotate the hook to reverse the barb direction within the confined space
Solution Approach 1:
The hook holder is designed to rotate dynamically within the confined space of the fish's stomach. The rack and pinion mechanism enables the hook holder to rotate up to 200 degrees, transforming the static gripping function into a dynamic rotation-capable system that can reverse barb direction while maintaining secure hook engagement
Solution Approach 2:
The invention adds a rotational dimension to the conventional linear manipulation approach. By introducing rotational movement around the longitudinal axis of the device, the system can change the orientation of the hook's barb from multiple angular positions, enabling the fisherman to reverse the barb direction without removing the hook from the confined space
2Ease of operation
If the fisherman manually inserts their hand into the fish's mouth to remove the hook, then they can directly manipulate the hook, but this creates safety risks and is impractical for deep lodged hooks
Solution Approach 1:
The device acts as an intermediary tool that extends the fisherman's reach into the fish's stomach without requiring manual insertion. The tubular housing and extending bar provide a protected channel through which the hook holder can access and manipulate deep-lodged hooks, eliminating direct contact between the fisherman's hand and the hazardous environment inside the fish
3Productivity
If the hook is removed without rotation, then the removal process is simpler, but the barb may re-engage the fish's tissue during extraction
Solution Approach 1:
The device performs preliminary rotation of the hook holder to reposition the barb orientation before extraction. By rotating the hook holder up to 200 degrees using the rack and pinion mechanism, the system preliminarily orients the barb away from the fish's tissue path, ensuring that when the hook is pulled out, the barb cannot re-engage the tissue during the extraction motion
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables effective and safe removal of fish hooks from within a fish's organs without re-engaging the barb, allowing for the extraction of both 'J' and 'Circle' hooks, reducing the risk of injury to the fish and eliminating the need for manual insertion into the fish's mouth.
Implementation Method 1
A distal end of the extending bar may include a rack that is configured to interface with a pinion within the removal tool. The rack may be configured to move in a first direction responsive to the trigger being pressed, and move in a second direction responsive to releasing the trigger.
Implementation Method 2
The pinion may be configured to interface with the rack, and convert linear force received by the rack into rotational force. Responsive to the pinion rotating, the hook holder may simultaneously rotate.

AI summary
Embodiments disclosed herein describe systems and methods for a device configured to reverse the direction of a fish hook up to two hundred degrees deep within a fish's gullet. This may allow the hook to be extracted without a barb of the hook re-engaging itself into the fish's tissue, as well as without the fisherman inserting their hand into the fish's mouth.
