Firearm Magazine Extension Using Locking Tabs and Spring Plate Orifices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearm magazine extenders are often difficult to couple with Original Equipment Manufacturer (OEM) magazines, are unreliable, not durable, and aesthetically unappealing, limiting their ability to provide a greater number of ammunition rounds.
Innovation Solution
A firearm magazine extension article comprising an extension spring stop and an extension body with locking tabs and spring plate orifices that securely couple to the OEM magazine, using a modified spring plate with a longer tab to prevent lateral movement and enhance stability, and an extension body that secures to the spring stop to increase ammunition capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If magazine extenders are coupled to OEM magazines, then ammunition capacity is increased, but coupling difficulty and reliability deteriorate
Solution Approach 1:
The magazine extender is divided into separate components: an extension body and a spring stop assembly. This segmentation allows each component to be optimized independently for secure attachment while maintaining ease of installation and removal from the OEM magazine.
Solution Approach 2:
The spring stop assembly nests within the extension body, with the spring stop positioned inside the extension body's cavity. This nested configuration reduces overall complexity while ensuring secure coupling between components and the magazine.
2Quantity of substance
If magazine extenders are coupled to OEM magazines, then ammunition capacity is increased, but ease of operation deteriorates
Solution Approach 1:
The spring stop is pre-assembled with the extension body, and the spring is pre-loaded into the spring stop. This preliminary assembly simplifies the field installation process, requiring only attachment to the magazine without complex assembly steps.
3Quantity of substance
If magazine extenders are coupled to OEM magazines, then ammunition capacity is increased, but durability deteriorates
Solution Approach 1:
The magazine extender utilizes composite construction with the extension body and spring stop assembly combining different material properties. The spring component provides elastic durability while the body components provide structural strength, creating a durable composite assembly.
Solution Approach 2:
The spring stop features a curved or contoured design that distributes mechanical stresses more evenly across the coupling interface with the magazine. This curvature enhances durability by preventing stress concentration at sharp corners or flat surfaces.
4Quantity of substance
If magazine extenders are coupled to OEM magazines, then ammunition capacity is increased, but aesthetic appearance deteriorates
Solution Approach 1:
The extension body is designed with aesthetic considerations for its external surfaces that are visible when attached to the magazine. The spring stop remains concealed within the extension body, allowing aesthetic quality to be applied selectively to visible portions while maintaining functional design elsewhere.

AI summary
A firearm magazine extension article generally comprises; an extension spring stop that couples to a distal end of an OEM firearm magazine, and an extension body that couples to the extension spring stop. The extension body further comprises locking tabs receivable by the extension spring stop to secure it and the whole of the article to the OEM firearm magazine. To deter any lateral movement by the article and to further secure the article, the extension spring stop comprises a first spring plate receiving orifice to receive a spring plate tab, and the extension body comprises a second spring plate receiving orifice to also receive the spring plate tab.
