Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional fishing hooks often snag on weeds, trees, and debris, leading to reduced fishing success and potential loss of lures due to entanglement, as existing weed guards are not adjustable and expose the sides of the hook to vegetation.

Innovation Solution

A weed guard body design for fishing hooks that includes a central attachment member and outer members, with adjustable guard members to shield the hook from entanglement, allowing for positional adjustment to reduce snagging risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional weed guards are disposed immediately above the distal end of the hook, then the hook is protected from above, but the sides of the hook are exposed to the weed bed causing entanglement

Engineering Contradiction:

Improvehook entanglement with weedsVSAvoidweed guard position adjustment

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The weed guard is designed with adjustable positioning capabilities, allowing it to be moved to different locations along the hook (proximal end, distal end, or intermediate positions). This dynamic positioning enables the guard to adapt to various fishing conditions and weed densities, resolving the contradiction between providing comprehensive protection and maintaining flexibility in different fishing scenarios.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The weed guard system is divided into separable components that can be independently positioned and attached at different locations on the hook. This segmentation allows the guard to be strategically placed to protect specific vulnerable areas of the hook while leaving other areas exposed as needed, thereby preventing entanglement without sacrificing adaptability.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the weed guard position and height are fixed, then the structure is simple, but it cannot adapt to different fishing conditions and weed densities

Engineering Contradiction:

Improveweed guard positioning flexibilityVSAvoidadjustable mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The weed guard is pre-configured with attachment points and positioning features that enable quick adjustment to different locations on the hook. This preliminary preparation allows anglers to rapidly reposition the guard between casts or fishing sessions without requiring complex adjustment mechanisms, thus achieving adaptability while minimizing added complexity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The weed guard design incorporates self-aligning features and intuitive attachment mechanisms that allow the angler to easily reposition the guard without specialized tools or complex procedures. The guard essentially serves itself by providing built-in positioning capabilities that are simple to operate, balancing adaptability with structural simplicity.

Inventive Principle:

Principle #25Self-service

AI summary

A weed-guarded hook assembly includes a first weed guard body that is attached to a fishing hook. The first weed guard body defines at least one aperture that is configured to receive a weed guard member. The weed guard member can extend through an eyelet so as to define first and second segments of the weed guard member. The first segment can extend into a first aperture of the first weed guard body, and the second segment can extend into a second aperture of the first weed guard body.
