Dry Fire Training Magazine With Automatic Trigger Cycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dry firing training devices for firearms require manual resetting of the trigger and hammer, which is inconsistent with live ammunition fire and not desirable for training, as they lack automatic cycling of the firing mechanism.
Innovation Solution
A dry firing training magazine with a trigger interface member biased by a spring, coupled to a pivoting lever that actuates a sound-producing element, such as a leaf spring, to simulate the hammer release and firing sound, allowing for consistent trigger control practice without manual resetting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual resetting of trigger and hammer is used in dry firing training, then the training device structure is simple, but the training realism and consistency with live ammunition fire deteriorates
Solution Approach 1:
The patent creates a simplified copy of the live fire mechanism within the magazine. The trigger interface member and pivoting lever replicate the hammer release action, while the sound-producing element copies the firing sound. This allows realistic training without needing the full complex firearm mechanism, resolving the contradiction between simplicity and realism.
2Device complexity
If manual action resetting is required, then the device structure is simpler, but the trigger control training effectiveness deteriorates
Solution Approach 1:
The magazine system performs the resetting function automatically through its own internal mechanism. When the trigger is pulled, the trigger interface member moves, which through the pivoting lever activates the sound-producing element and simultaneously resets the trigger interface member to its initial position via the biasing member. This self-service mechanism eliminates the need for manual resetting, improving training effectiveness without significantly increasing complexity.
3Reliability
If automatic cycling mechanism is added to simulate live ammunition fire, then the training consistency with live fire improves, but the device complexity increases
Solution Approach 1:
The magazine serves multiple functions: it stores ammunition (traditional function) and simultaneously acts as a dry fire training device with automatic trigger cycling and sound production. The trigger interface member and pivoting lever mechanism provide both the cycling function and the sound activation function. This multi-functionality allows the system to achieve training consistency with live fire without adding separate complex mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables consistent and realistic dry firing training by automatically simulating the hammer release and firing sound, enhancing trigger control skills without the need for manual action resetting, thus improving training efficacy.
Implementation Method 1
a trigger interface member which protrudes upwards from the magazine body and which is configured to be pushed by an action of pulling a trigger of a firearm into which the magazine body is inserted, the trigger interface member being biased by a biasing member
Implementation Method 2
The sound-producing element may include a leaf spring which produces a clicking sound when bent by the pivoting lever pushing against it

AI summary
A device for a dry firing training assembly includes a magazine body, and a trigger interface member which protrudes upwards from the magazine body and which is configured to be pushed by an action of pulling a trigger of a firearm into which the magazine body is inserted, the trigger interface member being biased by a biasing member. A pivoting lever is coupled to the trigger interface member. The pivoting lever is arranged to pivot about a pivot and to actuate a sound-producing element.
