Weedless Lure Body Structure for Snag-Free Fish Hooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing hooks and lures face challenges in avoiding snagging on weeds and ensuring secure fish hooking, particularly in shallow waters, due to design limitations that hinder successful retrieval and often result in lost catches.
Innovation Solution
The development of a weedless lure body with a hollow elliptical cone shape and flexible materials, combined with a hook design that embeds the shank within the cone's side wall and a braided wire connection, allowing the lure to collapse upon fish capture, preventing snagging and enhancing fish engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a guard or protective structure is designed around the hook to avoid contact with weeds, then the hook is protected from snagging on weeds, but the ability to securely hook the fish is reduced due to the geometry of the lure
Solution Approach 1:
The lure body is divided into distinct sections: a head portion, a body portion, and a tail portion. The hook is positioned within the head portion, separated from the main body. This segmentation allows the hook to be protected from weeds by the lure body while still being accessible to fish through the mouth opening, resolving the contradiction between weed protection and fish hooking capability.
Solution Approach 2:
The hook is nested within the head portion of the lure body, which acts as a protective container. The hook shaft extends through the head portion and connects to the body, while the hook point remains accessible through the mouth opening. This nesting structure protects the hook from snagging on weeds while maintaining its ability to secure fish.
2Object-affected harmful factors
If a latch mechanism is added to engage the barbed end of the hook to keep it out of weeds, then protection from snagging is improved, but the device complexity increases and the design fails when fish bite from side angles
Solution Approach 1:
The complex latch mechanism is removed entirely. Instead, the hook is directly integrated into the lure body structure, with the hook shaft extending through the head portion and connecting to the body. The hook point is positioned to be accessible through the mouth opening without requiring any moving parts or engagement mechanisms, simplifying the design while maintaining weed protection.
Solution Approach 2:
The hook and lure body are merged into a single integrated structure. The hook shaft is directly connected to the body portion, eliminating the need for separate latch mechanisms. This integration simplifies the design while the head portion continues to protect the hook from snagging on weeds.
3Reliability
If the hook is exposed to allow fish to bite, then fish engagement is improved, but any part of the wire hook including the barbed end can easily snag or pick up weed it touches
Solution Approach 1:
Different parts of the lure have different properties: the head portion provides protection for the hook shaft, while the mouth opening provides access for the hook point. The hook point is locally positioned to be accessible to fish through the mouth opening, while the rest of the hook remains protected within the head portion, resolving the contradiction between fish engagement and weed snagging.
Solution Approach 2:
The hook is positioned in three-dimensional space within the head portion, with the hook point extending through the mouth opening. This spatial arrangement allows the hook to be protected from weeds in most dimensions while remaining accessible to fish through the mouth opening, effectively separating the protection and engagement functions in different spatial zones.
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
The design ensures secure fish hooking and prevents snagging, enabling successful retrieval and protection from underwater obstacles, with enhanced eel-like action and durability in various water conditions.
Implementation Method 1
The casting lure body (12) includes a flexible tubing housing (15)
Implementation Method 2
The deformable lure body (60) is configured to collapse upon itself in use for retrieval, with a fish hooked onto the hook

AI summary
A weedless lure body has a hollow elliptical cone shape, with an opening in an elliptical shape. The body further includes a first side wall and a second side wall extending downward from a top of the hollow elliptical cone. A shank of a hook is formed with grabbing barbs, which are embedded in the second side wall. The barbed end is fixed relative to the second side wall, transversely within the opening, and vertically below the open end of the weedless lure body in use. The weedless lure body collapses upon itself in use for retrieval, with a fish on the hook.
