Fish Hook Removal Device Shank Alignment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Barbed fishing hooks are difficult to remove from skin without causing additional tissue damage and increasing the risk of infection when accidentally lodged, as the barb can lead to further pain and complications if not properly guided out during removal.
Innovation Solution
A hand-held fishing hook removal device with a forked tip and removal hook that applies downward pressure on the shank of the fishing hook, aligning the barb with the entry wound for safe removal by combining downward pressure and rearward motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a barbed fishing hook is removed from skin without proper guidance, then removal speed is increased, but tissue damage and infection risk increase
Solution Approach 1:
The device introduces an intermediary tool between the user and the fishing hook. The forked tip engages the shank while the removal hook engages the curve, providing controlled guidance throughout the extraction process. This intermediary mechanism ensures the barb follows a predetermined safe path out of the wound, preventing tissue damage while maintaining efficient removal.
Solution Approach 2:
The device performs preliminary alignment of the barb with the entry wound before actual extraction occurs. The forked tip and removal hook work together to position the barb correctly on the shank, ensuring it will exit through the original wound channel. This preliminary positioning prevents unpredictable barb movement during removal that could cause additional tissue damage.
2Object-affected harmful factors
If downward pressure is applied to the shank to align the barb, then tissue damage is reduced, but device complexity increases
Solution Approach 1:
The device merges multiple functions into a single integrated tool. The forked tip and removal hook are combined on one shaft, allowing simultaneous application of downward pressure and rearward motion. This integration achieves precise barb alignment without requiring multiple separate tools or complex mechanical systems, thus limiting the increase in device complexity.
Solution Approach 2:
The device segments the removal action into two distinct components: downward pressure applied by the forked tip on the shank, and rearward motion applied by the removal hook on the curve. This segmentation allows each component to perform its specific function efficiently, achieving precise barb alignment through coordinated simple motions rather than complex mechanisms.

AI summary
A fish hook removal device (1) used for removing fishing hooks (11) from human skin. The fish hook removal device applies downward pressure on a shank (15) of a fishing hook via a forked tip (4) located on a distal end ( ) of a shaft (3) extending from a handle (2). A removal hook (10) extends from the shaft and engages a curve (13) of the fish hook to apply a rearward motion to the curve of the fishing hook. The simultaneous downward pressure and rearward motion aligns a barb (12) of the fishing hook with an entry point of a wound (18) as the barb is removed from the wound.
