Retractable Barb Fishing Hook for Secure Catch and Gentler Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barbless fishing hooks struggle with secure hooking and retention of fish, while traditional barbed hooks cause injury during removal.
Innovation Solution
A fishing hook with a removable barb that initially hides within the hook body and extends outwardly after penetration, ensuring secure hooking and minimizing injury during removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional barbed hook is used, then secure hooking and retention of fish is improved, but injury to fish during removal increases
Solution Approach 1:
The barb is designed to be movable rather than fixed, transitioning from a retracted position during insertion to an extended position during retention. This dynamic configuration allows the barb to provide secure retention after hooking while minimizing injury during the removal process, as the barb can be pushed back into the groove to reduce profile when extracting the hook.
Solution Approach 2:
The hook is divided into functional segments: a fixed groove structure in the hook shaft and a separate movable barb component. This segmentation allows the barb to be independently positioned - retracted during insertion to minimize damage, and extended during retention to maximize security. The groove and barb work as separate but coordinated elements.
2Object-affected harmful factors
If a barbless hook is used, then fish injury during removal is reduced, but secure hooking and retention deteriorates
Solution Approach 1:
The barb transitions from a retracted state (appearing barbless during insertion) to an extended state ( providing retention after hooking). This dynamic behavior allows the hook to function as barbless during the critical insertion phase to minimize injury, then automatically provides barbed retention security once the fish is hooked.
Solution Approach 2:
The barb is pre-positioned in a retracted state within the groove before the hooking action occurs. This preliminary configuration ensures that during the critical insertion phase, the hook appears and functions as barbless, minimizing injury to the fish. The barb then activates afterward to provide retention.
3Reliability
If a movable barb mechanism is added, then fish retention and reduced injury are improved, but device complexity increases
Solution Approach 1:
The complexity is managed by segmenting the barb into a separate movable component that interacts with a simple groove structure in the hook shaft. This segmentation allows the barb to be independently positioned without requiring complex mechanisms - it can be pushed into the groove for retraction or allowed to extend for retention, keeping the overall structure relatively simple while achieving the desired functionality.

AI summary
A fishing hook apparatus having one or more removable barbs that may be initially hidden in the body of the hook and which may become extended outwardly from the hook after a fish is caught on the hook. The extendable barbs are configured so they are forcibly urged from a first barb position proximate the hook to a second barb position in which the barb extends outwardly from the hook. The extendable barb has first and second barb ends and is disposed for angular movement with respect to the hook from the extendable barb first end, and the second barb end moves along an arcuate path from the first barb position to the second barb position. A band may be included, circumferentially encircling the hook, slidably movable from first to second band positions. When in the first band position, each barb is held in a slot by the band. When in the second band position, the barb moves into its second position and extends outwardly from the hook.
