Flared Double Fish Hook Wedge Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double fish hooks tend to slide and dislodge from fish under pressure, leading to loss due to their design where hooks are typically set at 45-120° and lie in a single plane, causing them to tear the fish's mouth.
Innovation Solution
A double fish hook design with a bifurcation point where the angle between the two bends increases from about 5-15° to 30-90°, creating a wedge effect that secures the hooks in opposite directions, preventing sliding and dislodgment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If double fish hooks are set at 45-120° and lie in a single plane, then the hook structure is simple and easy to manufacture, but the hooks slide and dislodge from fish under pressure
Solution Approach 1:
The patent transitions the hook design from a two-dimensional planar configuration to a three-dimensional flared structure. The bends flare outward from the bifurcation point, creating a wedge shape that extends in the radial dimension. This dimensional change prevents sliding and dislodgment by distributing forces across multiple spatial planes, thereby improving reliability without excessive complexity.
Solution Approach 2:
The patent introduces asymmetry in the angular configuration of the bends. Instead of symmetric angles maintained throughout, the bends flare with increasing separation angles from the bifurcation point toward the points. This asymmetric angular progression creates a wedge effect that enhances holding power while maintaining manufacturing feasibility.
2Reliability
If the angle between bends is constant, then the manufacturing process is simpler, but the holding power against dislodgment is reduced
Solution Approach 1:
The patent varies the angular parameter along the length of the bends. The separation angle between bends increases progressively from the bifurcation point toward the points, creating a flared wedge shape. This parameter change optimizes resistance to dislodgment by distributing mechanical forces across varying angles, balancing improved reliability with manufacturability.
3Object-affected harmful factors
If hooks lie in a single plane, then the structure is simpler, but the force distribution causes tearing of the fish's mouth
Solution Approach 1:
The patent moves the hook structure from a single-plane configuration to a multi-dimensional flared arrangement. The bends flare outward in three-dimensional space, creating a wedge shape that distributes pulling forces across different spatial directions. This reduces concentrated stress on the fish's mouth tissue, minimizing tearing while maintaining structural feasibility.

AI summary
A flared double fish hook having a pair of shanks, said pair of shanks adjacent one another up to a bifurcation point; the shanks bifurcating at said bifurcation point to each form a bend ending in a point; the shanks being separated by an first angle at the bifurcation point, and a second larger angle at the points, such that the bend portion of the double fish hook flares.
