Firearm Magazine Adapter Clamshell Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm magazine adapters often have moving parts, detachable non-native magazines, elements attached to the firearm rather than the magazine, and require firearm modification, which compromises durability and usability.
Innovation Solution
A magazine adapter with clamshell halves and assembly screws that securely attaches to a non-native magazine without moving parts, ensuring the magazine is non-removably affixed when secured in a firearm's magazine well and removably affixed when not, with all elements attached to the magazine or adapter, not the firearm, and no firearm modification is required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If prior art adapters are used, then non-native magazines can be attached to firearms, but the adapters have moving parts that reduce durability
Solution Approach 1:
The adapter is divided into two clamshell halves that can be assembled around the non-native magazine. This segmentation allows the adapter to be constructed from multiple rigid parts that work together to secure the magazine, eliminating the need for moving parts while maintaining adaptability to different magazine types.
Solution Approach 2:
Instead of having the adapter attach to the firearm and allow magazine removal (prior art approach), this invention inverts the logic by having the magazine attach to the adapter in a fixed position. The adapter's clamshell halves are designed to receive and securely hold the non-native magazine, reversing the traditional attachment hierarchy to eliminate moving parts.
2Ease of operation
If prior art adapters allow magazine detachment while secured in magazine well, then ease of removal is improved, but reliability of connection during use deteriorates
Solution Approach 1:
The adapter provides dynamic attachment characteristics through its clamshell design. When the adapter is inserted into the magazine well, the clamshell halves close around the non-native magazine, creating a fixed and secure connection. The design inherently provides both states: secure attachment during use and ease of removal when needed, without requiring additional mechanisms.
3Ease of manufacture
If adapter elements attach to the firearm rather than the magazine, then ease of installation is improved, but adaptability to different magazines deteriorates
Solution Approach 1:
The adapter is designed with universal applicability through its clamshell half structure that can accommodate multiple types of non-native magazines. The interior slot and clamshell geometry are designed to work with various magazine configurations, making the adapter multi-functional and adaptable to different firearm-magazine combinations without requiring firearm-specific modifications.
4Reliability
If firearm modification is required for adapter use, then adapter security in magazine well is improved, but ease of operation deteriorates
Solution Approach 1:
The adapter serves as an intermediary component between the firearm's magazine well and the non-native magazine. The clamshell halves with their interior slot create a mediating structure that interfaces with the magazine well geometry and simultaneously secures the non-native magazine, eliminating the need for direct firearm modification while ensuring secure attachment.

AI summary
A firearm magazine adapter to be affixed to a non-native magazine to allow the adapted magazine to fit and function in a firearm that normally cannot accept the non-native magazine. Embodiments comprise two or three primary elements: two clamshell halves for the body or a one-piece body, and an ejector which is captive, for use with a non-native magazine, in the body. In one embodiment the magazine adapter is free of moving parts. In one embodiment, two screws hold the clamshell halves together and secure the ejector via a partial cylindrical negative volume. In use, the assembly is permanently and removably affixed to a non-native magazine. A single, unmodified release on the firearm releases the adapted magazine from the firearm.
