Locking Box Magazine Safety Device for Firearm Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm safety devices either allow locked firearms to accept magazines or live ammunition, posing safety and legal concerns, or add external bulk that prevents proper fitting in storage containers, and similar issues exist for tools with barrel and magazine assemblies.
Innovation Solution
A locking box magazine safety device that inserts into the magazine well, featuring a key-operated lock and chamber plug, immobilizing the barrel and preventing ammunition insertion, while maintaining the firearm's original profile for transport and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a key-operated locking mechanism is used to secure the firearm, then the firearm is rendered inert and secure, but the locked firearm may still accept a magazine or live ammunition
Solution Approach 1:
The invention merges the locking mechanism with the magazine well occupation. The safety device simultaneously performs two functions: locking the action via key-operated mechanism and occupying the magazine well to prevent magazine insertion. This combination resolves the contradiction by ensuring that when the firearm is locked, it cannot accept ammunition through either the action or magazine well.
Solution Approach 2:
The safety device is nested within the magazine well of the firearm. The magazine body portion fits inside the magazine well space, and the locking mechanism is contained within the safety device structure. This nesting approach allows the safety device to occupy the magazine well internally without adding external bulk, while still preventing magazine insertion and maintaining firearm security.
2Reliability
If an external cable or chain lock is used to secure the firearm, then the firearm is locked, but it will no longer fit properly in storage containers or holsters
Solution Approach 1:
The safety device is designed to nest within the existing magazine well dimensions of the firearm. By fitting inside the magazine well space rather than extending externally, the device maintains the firearm's original external profile, allowing it to fit in storage containers and holsters designed for the unmodified firearm.
Solution Approach 2:
The invention transitions from external locking (cable/chain locks that extend outward) to internal locking (a mechanism contained within the magazine well boundaries). This dimensional shift from external to internal placement resolves the contradiction by providing security without altering the external shape or adding bulk.
3Reliability
If a locking mechanism is designed to prevent magazine removal, then the action is secured, but the device complexity increases
Solution Approach 1:
The invention combines the magazine follower function with the locking mechanism operation. The magazine follower serves dual purposes: it normally feeds ammunition and also acts as the operating element that, when pressed, releases the locking arm to allow removal of the safety device. This merging reduces complexity by using an existing component for multiple functions rather than adding separate release mechanisms.
Solution Approach 2:
The safety device utilizes the firearm's own magazine release mechanism and magazine follower to operate its locking and release functions. The magazine follower, which is part of the firearm's existing architecture, is harnessed to trigger the release of the locking arm. This self-service approach reduces device complexity by leveraging existing firearm components rather than requiring entirely separate control systems.

AI summary
A locking box magazine safety device, comprising a magazine body comprising a rigid material shaped to conform to the internal dimensions and features of a box magazine well in a magazine-operated device; a lock cylinder comprising a key-operated lock and an operating rod, the operating rod configured to move when the appropriate key is used in the key-operated lock; and a pivoting arm configured to pivot about an axis, configured to be fixed in place by the movement of the operating rod, and configured to obscure the action of a magazine-operated device when fixed in place.
