Rotatable Fish Hook With Swivel Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard treble hooks have limited rotational ability, leading to leverage issues that cause the hook to tear out of a caught fish's mouth, resulting in reduced catch success and lost fish, and require replacement of existing lures for functionality.
Innovation Solution
A rotatable treble hook design featuring a rotation mechanism that isolates the barb and shank from the attachment piece, allowing them to spin freely while remaining connected to a fishing lure, preventing leverage and enabling use with existing lures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard treble hook is used with limited rotational ability, then the hook structure is simple and stable, but the hook gets stuck in a locked position causing leverage against the stopped hook which makes it tear out of the fish's mouth
Solution Approach 1:
The patent applies the dynamics principle by introducing a rotating mechanism that allows the hook assembly to dynamically adjust its orientation during fishing operations. The hook can rotate freely around the attachment piece, transforming from a static structure to a dynamic one that adapts to fish movements and leverage forces, preventing the hook from getting stuck in locked positions.
Solution Approach 2:
The patent segments the hook assembly into distinct rotational components: the attachment piece that connects to the lure, the rotating mechanism, and the hook itself. This segmentation allows independent rotation of the hook relative to the attachment piece, enabling the hook to move freely while maintaining connection to the lure, thus resolving the contradiction between structural stability and rotation freedom.
2Reliability
If a rotating treble hook is implemented to spin freely in any direction, then the leverage causing hook tear-out is eliminated, but the device complexity increases requiring additional rotation mechanism components
Solution Approach 1:
The patent employs the nesting principle by integrating the rotation mechanism within the existing hook structure. The rotating components are nested within or around the hook assembly, allowing the rotation function to be incorporated without significantly increasing external dimensions or overall complexity. The rotation mechanism is concealed within the hook's structural envelope.
Solution Approach 2:
The patent introduces an intermediary rotating mechanism that mediates between the stationary attachment piece and the moving hook. This intermediary component enables free rotation while maintaining structural connection, allowing the hook to spin freely in any direction without requiring complex external mechanisms, thus resolving the contradiction between reliability improvement and device complexity.
3Adaptability or versatility
If an existing lure is used with a hook that can freely rotate, then conversion of existing lures is enabled without replacing them, but the attachment mechanism must accommodate both stationary and rotating components
Solution Approach 1:
The patent applies the universality principle by designing the attachment piece to serve multiple functions: it connects to existing lures while simultaneously housing the rotation mechanism. This multi-functional design allows the attachment piece to maintain compatibility with standard lure configurations while enabling the advanced rotation capability, thus resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The patent merges the attachment function and rotation mechanism into a single integrated assembly. The attachment piece is combined with the rotating components, allowing the entire assembly to attach to existing lures while providing free rotation. This merging eliminates the need for separate attachment hardware and rotation mechanisms, enabling conversion of existing lures without significant complexity increase.

AI summary
A rotatable fish hook is configured for attachment to a legacy fishing lure. The rotatable fish hook may comprise: a barb; an attachment piece for connecting the hook to a fishing lure; and a rotation mechanism, configured to rotationally isolate the barb from the connecting piece. The barb is free to rotate while the attachment piece remains stationary. The rotatable fish hook may comprise: a shank and a bend connected to the shank at a first end and the shank connected to the barb at a second end. The rotation mechanism is configured to rotationally isolate the shank, the bend and the barb from the attachment piece. The shank, the bend and the barb are free to rotate while the attachment piece remains stationary.
