Solution Overview

Problem

Conventional tackle boxes fail to securely store elongate flexible tube flies and lures with articulated structures, leading to tangling and exposure of hooks, which can cause injuries during retrieval.

Innovation Solution

A storage container with a mandrel and mandrel anchor system, where the mandrel is used to detachably engage and secure tube flies, and resilient foam anchors with slits hold the mandrels, preventing movement and exposure of hooks, while optional hooks on the container secure conventional lures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If lures are stored in individual compartments in conventional tackle boxes, then the lures are contained and protected, but the lures move around and become tangled with other items

Engineering Contradiction:
Improvelure stabilityVSAvoidlure retrieval
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The invention divides the storage system into separate functional components: individual compartments for each lure, mandrels for securing elongate lures, and hook securing structures. This segmentation allows each lure to be independently contained and secured, preventing movement and tangling while maintaining easy access for retrieval.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mandrel acts as an intermediary device between the compartment and the elongate lure. The mandrel is inserted through the lure body and secured in the compartment, providing a stable anchoring point that prevents the lure from moving or tangling while allowing for easy retrieval by simply removing the mandrel.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If hooks are left exposed on lures in compartments, then the lures are easily accessible, but persons may inadvertently injure themselves on the hooks

Engineering Contradiction:
Improvelure accessibilityVSAvoidhook injury risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the hook from its traditional exposed position on the lure and relocates it to a dedicated hook securing structure within the compartment. The hook is inserted into a receptacle or secured by a retaining mechanism that keeps it accessible for fishing operations but protected from causing injury during storage and retrieval.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention employs disposable or replaceable hook securing mechanisms such as foam pads with slits, retaining clips, or disposable hook holders that can be easily replaced if worn or damaged. These simple, low-cost mechanisms provide effective hook protection without requiring complex or expensive safety systems.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Quantity of substance

If tube flies are stored in conventional tackle boxes, then the storage space is utilized, but the tube flies become knotted and tangled

Engineering Contradiction:
Improvestorage capacityVSAvoidtube fly integrity
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The invention applies preliminary action by inserting the mandrel through the tube fly body before storage and securing it in place within the compartment. This pre-securing action prevents the tube fly from moving, twisting, or knotting itself during storage, maintaining its integrity while efficiently utilizing storage space.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention transitions from two-dimensional compartment storage to three-dimensional mandrel-based suspension. The mandrel extends vertically through the tube fly, creating a dimensional anchor that prevents lateral movement and twisting, thereby eliminating tangling while maximizing vertical storage efficiency.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Adaptability or versatility

If lures with articulated structures are stored in conventional tackle boxes, then the storage accommodates various lure types, but the articulated structures do not effectively hold the lures

Engineering Contradiction:
Improvelure type accommodationVSAvoidlure holding security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The invention creates a universal storage system where the same mandrel and compartment structure can accommodate multiple lure types including tube flies, articulated lures, and conventional hooked lures. The mandrel can be positioned and secured in various configurations to suit different lure geometries, while the hook securing structures provide universal protection for all lure types with exposed hooks.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A storage container commonly referred to a “tackle box,” that detachably secures an elongate fishing lure, such as a tube fly or the like, within a chamber of a case using a mandrel for detachably engaging the lure and a mandrel anchor for detachably engaging the mandrel. In a disclosed embodiment, the mandrel anchor is formed of foam with slits received therein for receiving one or more mandrels. A distal end of each mandrel may include a clip for snugly engaging the lure to further hold the lure in place in the container.
