Fish Hook Spike Structure for Stronger Fish Retention

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing fish hooks often fail to securely retain fish once hooked, leading to fish shaking off or separating due to soft mouth parts, slack lines, or jumping, which complicates successful landing.

Innovation Solution

Incorporating an auxiliary spike or projecting member into the fish hook design to enhance retention, either as a unitary part of the hook or as a separate component, with various attachment methods to stabilize the spike relative to the hook.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional single fish hook is used, then the device complexity is low, but the reliability of fish retention is insufficient

Engineering Contradiction:

Improvefish retentionVSAvoidhook structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The fish hook is divided into functionally distinct segments: the traditional hook portion (eye, shank, point, barb) and the auxiliary spike portion. This segmentation allows each component to perform its specialized function - the hook for initial penetration and anchoring, while the spike provides additional retention by engaging the fish's oral structures, thereby improving overall reliability without significantly complicating the overall device

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The auxiliary spike is integrated with the hook in a nested configuration where the spike is positioned to extend from the hook's eye region toward the gap. The spike and hook share common structural elements (wire construction, attachment at the eye), creating a compact integrated design that improves retention while minimizing additional complexity

Inventive Principle:

Principle #7Nested doll (Nesting)

2Strength

If the fish hook has a simple structure, then the ease of manufacture is high, but the ability to resist fish separation is insufficient

Engineering Contradiction:

Improveresistance to fish separationVSAvoidhook production

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The manufacturing process merges the formation of the hook and spike into a single integrated operation. The wire is formed to create both the hook curvature and the auxiliary spike extension in one continuous process, eliminating the need for separate manufacturing steps for each component. This merging approach maintains ease of manufacture while significantly strengthening the fish's retention capability through the added spike engagement points

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If the spike is formed as a separate component, then the adaptability of the hook is improved, but the device complexity increases

Engineering Contradiction:

Improvespike attachment optionsVSAvoidassembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The eye region of the hook is designed to serve multiple functions: it acts as the attachment point for the fishing line, the structural connection for the hook shank, and the mounting location for the auxiliary spike. This universal design of the eye region allows flexible attachment configurations (integrated or separate spike components) without requiring additional specialized structures, thereby improving adaptability while controlling complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A fish hook having a spike that assists in resisting a fish separating from the fish hook once the fish is hooked by the fish hook. The spike can be integrally formed with the fish hook. Alternatively the spike can be part of a separate spike component that is attached to or supported on the fish hook. The fish hook can be a single fish hook, or be a fish hook of a multiple fish hook such as a double hook or a treble hook.
