Magazine Coupler Catch Geometry for Fast Secure Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magazine coupling devices for firearms are inefficient due to precise alignment requirements, susceptibility to damage, and limited flexibility in magazine orientation, leading to delays in firearm operation when switching between loaded magazines.
Innovation Solution
The development of a magazine coupling apparatus featuring couplers with symmetrically arranged catches on mating faces that can be rotated to align in two opposed configurations, allowing for secure engagement of two magazines with flexibility in orientation, reducing the need for precise alignment and enhancing operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protruding studs and receiving apertures are used to engage magazines, then coupling is achieved, but precise placement is required and studs can catch and break
Solution Approach 1:
The patent employs asymmetric catch designs where protruding catches on one magazine base plate engage with recessed catches on the opposing magazine. This asymmetric configuration provides self-aligning features that guide the magazines into proper engagement without requiring precise manual alignment, while the interlocking asymmetric shapes prevent accidental disengagement and reduce the risk of breaking during coupling operations.
2Reliability
If threaded rods are used to couple magazines, then connection is achieved, but the design is cumbersome and easily damaged by dirt and debris
Solution Approach 1:
The patent replaces complex threaded rod mechanisms with simple, robust catch designs that function as disposable or easily replaceable components. The catches are designed to be simple protruding and recessed features that can be integrated into the magazine base plate structure, eliminating the need for complex threading mechanisms that are prone to damage from dirt and debris. These simplified catch features are easier to manufacture and maintain.
3Reliability
If precise alignment is required for magazine coupling, then secure engagement is achieved, but delays occur in firearm operation
Solution Approach 1:
The patent incorporates preliminary alignment features in the catch design, such as tapered leading edges on protruding catches or guiding surfaces that automatically align the magazines as they approach each other during the coupling process. This preliminary self-alignment action occurs passively during the natural movement of bringing magazines together, eliminating the need for precise manual alignment and reducing the time required for magazine switching while ensuring secure engagement.

AI summary
The present disclosure provides apparatus and methods for coupling an item to another item. The apparatus comprises a coupler mounted on the item and comprising a mating face having a plurality of catches thereon, the plurality of catches comprising at least one complementary pair of catches positioned and shaped to be engaged with corresponding catches of another coupler having an identical mating face when mating faces of two couplers are facewise engaged with and rotated relative to each other to align with each other. The coupler may be implemented as a floor plate of a magazine, as a clip, or in other forms.
