Magazine Coupler Catch Layout for Fast Multi-Angle Attachment
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 arranging magazines, leading to delays in firearm operation.
Innovation Solution
A coupler system with symmetrically arranged catches on a mating face that allows for secure engagement of two magazines in multiple alignments, featuring inward and outward catches and peripheral ridges for flexible alignment and durability, enabling easy attachment and detachment without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a modified base plate with protruding studs and receiving apertures is used to engage magazines, then the magazines can be coupled together, 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 engage with recessed catches on the opposing magazine. This asymmetric configuration eliminates the need for precise alignment while maintaining secure coupling, as the asymmetric geometry guides the magazines into proper engagement automatically.
2Reliability
If a protruding base plate or threaded rod is used to couple magazines, then the magazines can be connected, but the design is cumbersome to engage and easily damaged by dirt and debris
Solution Approach 1:
Instead of using protruding elements that extend outward and are vulnerable to debris, the patent inverts the design by using recessed catches that receive protruding catches from the opposing magazine. This inversion protects the engagement mechanism from dirt and debris, as the recessed geometry shields the critical coupling surfaces.
3Adaptability or versatility
If a coupling device allows only one arrangement of magazines with opposite alignment, then the coupling is simple, but the angle between magazines cannot be modified
Solution Approach 1:
The patent creates a universal coupling mechanism where the catch design allows magazines to be coupled at multiple angles and orientations. The same catch structure that provides secure engagement also accommodates various configurations, enabling operators to attach magazines in different orientations depending on operational needs without requiring different coupling devices.

AI summary
The present disclosure provides apparatus 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.
