Solution Overview

Problem

Existing safety magazine systems risk damaging finely honed surfaces of firearms and can be unauthorizedly moved from the locked position, with locking elements often requiring long adjustment paths and being specific to certain weapon types.

Innovation Solution

A safety magazine design where the locking element adjusts backwards against the impact plate, minimizing surface contact and adjustment length, and can be securely locked and unlocked using a shorter mechanism, with options for manual or electrical actuation, preventing unauthorized use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the locking element engages in the barrel, cartridge chamber, or feed ramp area, then the safety magazine prevents unauthorized removal, but the locking element may damage the finely honed surfaces and can be moved out without authorization

Engineering Contradiction:
Improvesecurity of lockingVSAvoidsurface damage and unauthorized movement
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The locking element is extracted from the problematic areas (barrel, cartridge chamber, feed ramp) and relocated to engage with the impact plate instead. This removes the source of surface damage while maintaining the security function through engagement with a suitable target surface.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The impact plate serves as an intermediary component between the locking element and the firearm structure. It provides a dedicated engagement surface that protects the finely honed surfaces of the barrel and cartridge chamber while enabling secure locking through the form fit connection.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the locking element traverses a long path from unlocked to locking position, then it can engage securely, but the adjustment mechanism becomes larger and more complex

Engineering Contradiction:
Improvesecure engagementVSAvoidadjustment mechanism size and complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Instead of the locking element moving forward into the firearm to engage locking surfaces, the locking element is adjusted backwards against the impact plate for locking. This inverted approach shortens the adjustment path and simplifies the mechanism while achieving secure engagement through the form fit connection.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The impact plate is pre-positioned in the firearm structure to provide the locking engagement surface. This preliminary placement eliminates the need for the locking element to traverse a long path, as the engagement point is already in place to receive the locking element's backward adjustment.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the locking element engages in specialized recesses in the weapon, then secure locking is achieved, but the safety magazine can only be used for specially designed weapons

Engineering Contradiction:
Improvelocking securityVSAvoidcompatibility with different weapon types
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The locking element is designed to engage with the impact plate, a component that exists in various forms across different firearm types. This universal engagement approach allows the safety magazine to be adapted to multiple weapon types without requiring specialized recesses or modifications to the firearm structure.

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

Solution Approach 2:

Rather than requiring the firearm to have specialized locking recesses, the solution inverts the approach by having the locking element engage backwards against the impact plate. This reversal makes the system adaptable to existing firearm designs without requiring specialized modifications.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

The invention relates to a safety magazine (2) for a firearm (1), wherein the safety magazine (2) can be inserted into the magazine well or the magazine retainer (1a) of the firearm (1) and has a locking element (3, 17), wherein the locking element (3, 17) can be brought from an unlocked position into a locked position after the safety magazine (2) has been inserted into the firearm (1), and in the locked position a form closure is formed by the locking element (3, 17) and the firearm (1) in such a way that the form closure prevents the safety magazine (2) from being removed from the firearm (1), wherein an adjustment mechanism (6, 7, 17) and/or drive moves the locking element (3, 17) in the direction of the breechblock bottom (4) upon movement to the locked position.
