Tail Harness Fish Stringer for Quick Release Without Gill Injury

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing fish stringers often injure fish by being inserted through their gills or mouth, are difficult to attach and detach, and do not allow for easy removal of individual fish without causing further harm.

Innovation Solution

A fish stringer that attaches to the tail of the fish using a tail harness with adjustable loops and a swivel clip, allowing secure and quick attachment and detachment without harming the fish, and enabling easy release of individual fish.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a hook or line is inserted through the gills or mouth of the fish, then the fish can be securely attached to the stringer, but the fish is injured and stressed

Engineering Contradiction:

Improvesecure attachment of fishVSAvoidinjury and stress to fish

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Instead of inserting the stringer through the fish's mouth and gills (conventional approach), the invention inverts the attachment point to the tail portion of the fish. The tail harness with loops engages the tail, and the line attaches to the harness, completely avoiding insertion through sensitive areas like gills and mouth, thus eliminating injury and stress while maintaining secure attachment

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If traditional stringers are used, then fish can be attached, but attachment and removal are difficult and time-consuming

Engineering Contradiction:

Improvesecure attachment of fishVSAvoidattachment and removal ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The invention divides the attachment system into separate functional components: a tail harness with multiple loops for securing the fish tail, and a separate line with attachment mechanisms. This segmentation allows the fish to be quickly attached by simply looping the tail through the harness loops and engaging the attachment mechanism, and just as quickly removed by releasing the mechanism without complex manipulation

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The tail harness incorporates dynamic elements including adjustable loops that can be easily opened and closed, and a releaseable attachment mechanism that allows quick engagement and disengagement. These dynamic features enable rapid attachment and removal operations while maintaining secure holding when engaged

Inventive Principle:

Principle #15Dynamics

3Quantity of substance

If traditional stringers are used, then multiple fish can be stringed, but individual fish cannot be easily removed without causing harm

Engineering Contradiction:

Improvenumber of fish on stringerVSAvoidindividual fish removal ease

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

Each fish is independently secured through its own tail harness with separate loops and attachment points on the main line. This segmentation allows any single fish to be independently accessed and released by simply engaging the release mechanism at that specific location, without affecting other fish on the stringer. The system maintains the ability to hold multiple fish while enabling easy individual removal

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The tail harness acts as an intermediary component between the fish tail and the main line. It provides a dedicated attachment point with a release mechanism that can be independently activated for each fish. This intermediary structure allows selective release of individual fish without disturbing the rest of the fish on the stringer, and without requiring harmful manipulation of the fish bodies

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A fish stringer with a releasable connector designed to simplify and hasten the attachment and removal of a fish to a fish stringer, and even more particularly to a fish stringer that attaches to the tail portion of the fish and not the gills, fins, or mouth of the fish.
