Snapping Fish Stringer With Coated Cable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fish stringers are difficult to open and close while waist-deep in water, and the uncovered lines can cause trauma and damage to fish, leading to premature death.
Innovation Solution
A snapping fish stringer with a locking body, insert, and coated cable that easily opens and closes, allowing secure fish handling and minimizing fish trauma with a low-friction coating for smooth fish movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fish stringers are used, then fish can be held securely, but the stringer is difficult to open and close while waist-deep in water
Solution Approach 1:
The stringer is divided into separate components: a body portion and a closure mechanism that can be independently operated. The closure is segmented into a mouth and a snap button that can be opened and closed with one hand, even while waist-deep in water.
Solution Approach 2:
The closure mechanism is extracted as a separate, easily operable component from the main body. The snap button closure can be independently opened and closed without requiring manipulation of the entire stringer structure.
2Object-affected harmful factors
If uncovered lines are used in conventional stringers, then the structure remains simple, but the lines cause trauma and damage to fish leading to premature death
Solution Approach 1:
The cable is given a special smooth coating only in the portions that contact the fish (the body portion and the loop), while the rest of the stringer structure remains simple and uncovered. This localized modification reduces fish trauma without significantly increasing overall device complexity.
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
Facilitates easy fish loading and unloading, reduces fish trauma, and keeps fish alive longer by allowing easy attachment and detachment while maintaining secure holding.
Implementation Method 1
The cable has a low-friction coating which facilitates easy fish loading and unloading, and the fish can slide along the cable effortlessly

AI summary
A fish stringer has a locking body, an insert received in the locking body and a loop connected to the locking body and the insert. An insert-receiving cavity traverses into the locking body. The insert has a handle portion to be manipulated and a tongue portion within the insert-receiving cavity. A latching mechanism on the insert engages a latch receptacle on the locking body. The latching mechanism is a flexible arm with a tab. The flexible arm is deformed from an equilibrium position as the tab engages with the latch receptacle.
