Snap-On Weedless Lure Head for Hook Eye and Knot Coverage

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing weedless lures hang up in grass and underwater structures due to the exposed hook eye and knot, and knot, and specialty hooks that make the claim to be weedless.

Innovation Solution

A snap-on, bullet-shaped lure head that covers the areas where grass and underwater structures typically hang up, featuring a thru hole for line passage, a recessed area for soft plastic baits, and a locking mechanism to secure the fishing line, and a locking detent for orientation, and a recessed pocket to cradle the eye or shank for a weighted or non-weighted fishing hook.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing weedless lures are used, then they claim to prevent hanging up in grass and structures, but they still hang up due to exposed hook eye and knot

Engineering Contradiction:

Improveweedless performanceVSAvoidhanging up in grass and structures

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a bullet-shaped head as an intermediary component that covers the hook eye and knot area. This head acts as a mediator between the hook and the surrounding environment (grass/structures), preventing direct contact and eliminating the hanging up problem while maintaining the weedless claim.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The bullet-shaped head is designed as a simple, inexpensive component that can be easily manufactured and replaced. Rather than modifying complex existing lures, this disposable-like component provides an effective solution that can be attached to standard hooks, making the weedless function accessible and reliable.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Reliability

If a snap-on head is added to cover the hook eye and knot, then weedless performance improves, but device complexity increases

Engineering Contradiction:

Improveweedless performanceVSAvoidlure structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The lure is divided into separate functional components: the hook, the soft plastic bait, and the snap-on bullet-shaped head. This segmentation allows each component to be optimized independently and assembled in a modular fashion, reducing overall complexity while improving weedless performance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bullet-shaped head serves multiple functions simultaneously: it covers the hook eye and knot to prevent hanging up, provides a snap-on attachment mechanism for easy installation, and maintains a streamlined shape that doesn't interfere with lure action. This multi-functionality reduces the need for additional components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

One example embodiment includes a portion of an assembly when securing fishing line to a hook. The embodiment includes a method for a snap-on assembly to a hook. The embodiment may also allow for vertical swivel motion along a fixed axis once affixed to the hook. The embodiment is made of a flexible plastic material that allows the snap feature to expand and contract back to its original shape after attaching. The embodiment further includes an internal pocket for properly aligning and securing the eye of the hook. Furthermore, the embodiment provides a pocket that covers the leading edge of a soft plastic artificial bait.
