Solution Overview

Problem

Conventional muzzleloaders face challenges in quick reloading due to issues with wet non-pelletized powder, fouled mechanisms, accidentally loading spent primers, and the risk of dropping propellant or bullet, leading to missed opportunities and potential injuries.

Innovation Solution

A muzzleloading device with a shot holding chamber, plunger, nut, and O-rings that securely holds pelletized or non-pelletized propellant and projectile, allowing for efficient loading by aligning over the muzzle and actuating the plunger to dispense the charge and bullet into the barrel in one action, while preventing debris ingress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If conventional muzzleloading methods are used with separate handling of powder and bullet, then flexibility in loading is maintained, but loading time increases and risk of dropping propellant or bullet increases

Engineering Contradiction:
Improveloading timeVSAvoidloading procedure complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent combines the propellant charge and projectile into a single pre-assembled unit within the shot holder. This merging eliminates the need for separate handling of powder and bullet, reducing loading time and the risk of dropping components while maintaining a straightforward loading procedure through the single-shot dispensing mechanism.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The shot holder allows preliminary assembly of the propellant charge and projectile into a complete shot unit before loading. This pre-preparation of the complete shot eliminates time-consuming separate operations during the actual loading process, while the simple holder design keeps the procedure uncomplicated.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If manual handling of loose powder and bullet is used, then loading flexibility is maintained, but the risk of accidentally loading spent primers and fouled mechanisms increases

Engineering Contradiction:
Improveloading reliabilityVSAvoidloading operation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By combining the propellant charge and projectile into a single pre-assembled shot unit, the system eliminates the risks associated with separate handling of components. The integrated design ensures that only fresh, properly assembled shots are loaded, preventing accidental loading of spent primers or fouled mechanisms while maintaining simple operation through single-unit dispensing.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The shot holder system is designed for single-use or limited-use cycles, where the holder and its contents are discarded or replaced after each loading. This disposable approach eliminates the accumulation of fouled components and spent primers, ensuring high reliability while keeping the operation simple through consistent replacement rather than cleaning and maintenance.

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

3Productivity

If separate loading of powder and bullet is performed, then adaptability to different loading conditions is maintained, but loading speed decreases

Engineering Contradiction:
Improveloading speedVSAvoidloading condition adaptability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The shot holder enables preliminary assembly of complete shots with specific propellant charges and projectiles matched for optimal performance. This pre-preparation allows rapid loading of pre-configured shot units, increasing loading speed while maintaining adaptability through the ability to pre-assemble different shot configurations for various hunting conditions.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides dynamic adaptability by allowing the user to pre-assemble different shot configurations based on anticipated hunting conditions, then rapidly deploy the appropriate pre-configured shots. The shot holder design accommodates various shot compositions while enabling fast loading through the single-unit dispensing mechanism.

Inventive Principle:
Principle #15Dynamics
