Fly-box with Segmented Bobbin Compartments

Solution Overview

Problem

Fly fishermen face frustration due to tangled nymph rigs when storing and retrieving them from disorganized fly-boxes, which slows down the fishing process and complicates the enjoyment of fly-fishing trips.

Innovation Solution

A fly-box system featuring bobbins and hooks that allow tandem rigs to be securely stored and retrieved without tangling, using a hook-and-bobbin configuration that winds the fishing line around a cylindrical body with ridges, minimizing turns and space, and anchoring the bobbin to the fly-box foam to prevent entanglement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If nymph rigs are stored in a disorganized fly-box, then the fly-box can accommodate multiple rigs, but the rigs become tangled and difficult to retrieve

Engineering Contradiction:

Improvenumber of rigs storedVSAvoidease of retrieval

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The fly-box is divided into multiple compartments, with each compartment dedicated to storing a single nymph rig. This segmentation prevents rigs from tangling with each other while allowing multiple rigs to be stored simultaneously. Each compartment acts as an independent storage unit that maintains organization and facilitates quick retrieval of individual rigs.

Inventive Principle:

Principle #1Segmentation

2Volume of stationary object

If nymph rigs are stored loosely in a fly-box, then storage capacity is maximized, but tangling occurs during storage and retrieval

Engineering Contradiction:

Improvestorage capacityVSAvoidtangling

Core Design Contradiction:

Volume of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The fly-box is divided into multiple compartments, with each compartment dedicated to storing a single nymph rig. This segmentation prevents rigs from tangling with each other while allowing multiple rigs to be stored simultaneously. Each compartment acts as an independent storage unit that maintains organization and facilitates quick retrieval of individual rigs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The nymph rig is nested within its designated compartment, with the rig positioned inside the compartment boundaries. This nesting approach ensures that each rig is contained within its own space, preventing tangling while maximizing the use of available storage volume within each compartment.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Device complexity

If traditional fly-box storage is used, then no additional equipment is needed, but retrieval time increases due to tangling

Engineering Contradiction:

Improveequipment simplicityVSAvoidretrieval time

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The fly-box is divided into multiple compartments, with each compartment dedicated to storing a single nymph rig. This segmentation prevents rigs from tangling with each other while allowing multiple rigs to be stored simultaneously. Each compartment acts as an independent storage unit that maintains organization and facilitates quick retrieval of individual rigs.

Inventive Principle:

Principle #1Segmentation

AI summary

This includes a fly-box to organize flys and multi-fly rigs. It can hold a tandem rig with two or more fishhooks using a fishing line-winder to wind the tandem rig while the fishhooks remain attached.
