Solution Overview

Problem

Existing magazine extensions are unreliable in preventing the magazine from popping out upward during impact, and users need separate magazine holders for concealed carrying, which can be inconvenient.

Innovation Solution

A magazine extension with a steel locking plate that secures to the magazine well using a threaded through hole and a pocket clip integrated with a securing device, providing additional security and eliminating the need for external magazine holders.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a magazine extension is installed to extend magazine capacity, then the ammunition storage capacity is increased, but the reliability of preventing the magazine from popping out during impact deteriorates

Engineering Contradiction:
Improveammunition storage capacityVSAvoidreliability of preventing magazine from popping out
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The magazine extension is divided into separate functional components: the extension housing that increases capacity and the locking plate that provides security. This segmentation allows the locking plate to be specifically optimized for preventing pop-out while the extension housing focuses on capacity expansion.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking plate is integrated with the magazine extension assembly, combining the security function with the capacity extension function. The locking plate works in conjunction with the extension housing to provide both extended capacity and reliable prevention of pop-out during impact.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a separate magazine holder or holster is used for concealed carrying, then the security of carrying an extra magazine is improved, but the device complexity and user convenience deteriorate

Engineering Contradiction:
Improvesecurity of carrying extra magazineVSAvoidcomplexity of carrying system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The magazine extension integrates multiple functions into a single component: it extends ammunition capacity, provides locking security, and includes an integrated pocket clip for concealed carrying. This eliminates the need for separate magazine holders or holsters, reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The magazine extension serves multiple purposes: it increases storage capacity, provides security through the locking plate, and enables concealed carrying through the integrated pocket clip. This multi-functionality replaces what would traditionally require multiple separate accessories.

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

3Reliability

If a steel locking plate is added to secure the magazine extension, then the reliability of preventing pop-out during impact is improved, but the device complexity increases

Engineering Contradiction:
Improvereliability of preventing magazine from popping outVSAvoidcomplexity of magazine extension structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking function is separated into a distinct locking plate component that can be independently optimized for security while maintaining a relatively simple overall structure. This segmentation allows the locking mechanism to be straightforward without compromising reliability.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If an integrated pocket clip is added to the magazine extension, then the ease of concealed carrying is improved, but the device complexity increases

Engineering Contradiction:
Improveease of concealed carryingVSAvoidcomplexity of magazine extension structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pocket clip is integrated directly into the magazine extension assembly, combining the concealed carrying function with the capacity extension and security functions. This integration allows convenient concealed carrying without requiring separate holders or holsters.

Inventive Principle:
Principle #5Merging (Combining)
