Deformable Weedless Lure Body with Embedded Barbed Hook
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing hooks and lures struggle to avoid snagging on weeds, leading to difficulties in securely hooking fish and retrieving them successfully, especially in shallow waters.
Innovation Solution
The development of a weedless lure body in the shape of a hollow elliptical cone made of deformable material, combined with a hook design featuring a shank with grabbing barbs and a curved barbed end, which is embedded in the lure body and configured to collapse for retrieval.
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 compromised due to the geometry of the lure
Solution Approach 1:
Instead of protecting the hook from all directions with a rigid guard, the invention inverts the approach by making the lure body itself deformable and collapsible. The soft body collapses inward during retrieval to protect the hook, while maintaining an open structure during fishing that allows fish to access the hook from multiple angles.
Solution Approach 2:
The lure body transitions from a static protective structure to a dynamic, deformable structure that changes shape during different phases of use. The body collapses inward when retrieving to protect the hook, and remains expanded during fishing to allow fish access, providing adaptive protection rather than fixed geometry.
2Object-affected harmful factors
If a latch mechanism is added to keep the barbed end out of weeds, then weed contact is reduced, but the design fails when fish bite from side angles as the guard does not release
Solution Approach 1:
The lure body automatically performs the protection function without requiring a separate latch mechanism. The soft, collapsible body naturally closes around the hook during retrieval through its own deformation, eliminating the need for complex mechanical latches that fail to respond to side-angle bites.
Solution Approach 2:
The invention changes the physical state and shape of the lure body from rigid to deformable, allowing it to dynamically adjust its protective function based on the retrieval motion rather than relying on mechanical parameters of a latch system that cannot adapt to various bite angles.
3Reliability
If any part of the wire hook including the barbed end is exposed, then the hook can effectively catch fish, but it easily snags or picks up weed it touches
Solution Approach 1:
The invention segments the protective function from the hook itself by using a separate deformable body that collapses around the hook during retrieval. This allows the hook to remain exposed and functional for catching fish while the collapsible body provides selective protection during the retrieval phase when snagging occurs.
Solution Approach 2:
The collapsible body is pre-configured to automatically collapse and protect the hook during the retrieval motion before snagging can occur. This preliminary protective action happens naturally as the lure is pulled through water, preventing weed contact before it becomes a problem.
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 solution effectively prevents the hook from snagging on weeds, allowing fish to be hooked securely from various angles and facilitating successful retrieval, while also protecting the hook from getting caught during the catch process.
Implementation Method 1
The hollow elliptical cone is formed of a deformable material and is configured to collapse upon itself in use for retrieval, with a fish hooked onto the hook

AI summary
A weedless lure body having an hollow elliptical cone shape, has an oblique opening angled upward from an elliptical base along a first side wall of the weedless lure body. The body further includes a second side wall positioned around an opposing vertex to the first side wall. A shank of a hook is formed with grabbing barbs, which are embedded in the second side wall. The weedless lure body collapses upon itself in use for retrieval, with a fish on the hook. A casting lure includes a flexible tubing housing encapsulating a flexible braided wire. One end is attached to an interior side of an attachment end of the wire within the flexible tubing housing. A second end of the wire positioned below the first end is attached to a shank of a hook, the flexible tubing including an opening through which the barbed end of the hook extends.
