Solution Overview

Problem

Muzzle-loading firearms are cumbersome to load due to the need for single-handed manipulation of multiple components, leading to potential spilling of gunpowder and inefficient use of accessories like short starters, especially in hunting situations where precision and speed are critical.

Innovation Solution

A loading device comprising a first tubular body for containing a premeasured charge and a second tubular body with a delivery end that can be tilted to pour gunpowder into a muzzleloader while minimizing spillage, integrated with a short starter function and a lanyard attachment for hands-free operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional loading device with a chamber sized to receive the projectile is used, then the chamber can contain all load components, but the upper chamber portion becomes oversized for pouring purposes leading to gunpowder spillage

Engineering Contradiction:
ImproveaccuracyVSAvoidpouring precision
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The loading device is divided into two separate tubular bodies: a first tubular body for containing the projectile and a second tubular body for containing and pouring the gunpowder charge. This segmentation allows each component to be optimized for its specific function, with the second tubular body having a size suitable for precise pouring without the constraints of accommodating the projectile.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If multiple separate load components and accessories are manipulated single-handedly, then each component can be handled independently, but the loading process becomes slow and cumbersome

Engineering Contradiction:
Improvehandling flexibilityVSAvoidloading speed
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The loading device merges multiple load components (projectile, gunpowder charge, and accessories) into a single integrated apparatus consisting of two connected tubular bodies. This combination allows the hunter to load all components simultaneously in one operation rather than manipulating each component separately, significantly reducing the time and complexity of the loading process.

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If the chamber body is positioned outside the muzzle during pouring and ramming, then the inner diameter can match the caliber, but the loader must hold both the loading device and rifle in alignment with one hand

Engineering Contradiction:
Improvechamber-muzzle alignmentVSAvoidhands-free operation
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The loading device incorporates a flexible connector that allows the second tubular body (powder charge container) to be positioned dynamically. This flexibility enables the device to adapt to different positioning requirements during loading, allowing the user to hold the device more comfortably while maintaining proper alignment with the muzzle, thereby reducing the difficulty of hands-free operation.

Inventive Principle:
Principle #15Dynamics

4Ease of operation

If a conventional short starter is used with a load carrying device, then the short starter can push the projectile down the barrel, but the short starter must be extended through the entire length of the chamber before reaching the muzzle

Engineering Contradiction:
Improveshort starter effectivenessVSAvoidloading steps
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention extracts the short starter function from a separate accessory and integrates it directly into the loading device structure. The second tubular body itself serves as the short starter, eliminating the need for a separate short starter component and reducing the number of loading steps by allowing direct insertion into the muzzle without extending through the entire chamber length.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A load carrier for a muzzleloader having a muzzle, comprising a first assembly component and a second assembly component, the first assembly component comprising a tubular open-ended charge receiving body configured to receive a charge though an open end section of the charge receiving body with the second assembly component comprising a tubular delivery body comprising a delivery end section and a connector end section, the delivery end section having an external diameter so as to be insertable into the muzzle and a removeable cap engageable with the delivery end section. The connector end section of the second assembly component may be engageable with the open end section of the charge receiving body of the first assembly component. Insertion of at least a portion of the delivery end section into the muzzle during pouring facilitates consistent and speedy loading. The disclosure also provides associated methods.
