Firearm Training Barrel Mechanism for Continuous Firing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing replica guns with laser simulation systems are limited by the slide and magazine mechanism, which prevents continuous firing when the magazine is empty, requiring frequent reloading and not providing a realistic firing experience.
Innovation Solution
A retrofittable barrel mechanism with an extendable projection or finger that simulates the presence of a pellet in the magazine, allowing continuous firing without actual pellets, and includes a pellet ejection system to mimic spent casing ejection, along with a pressure relief valve to reduce ejection force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the magazine mechanism is used to control firing, then the firearm operates with realistic ammunition consumption, but continuous firing is prevented when the magazine is empty
Solution Approach 1:
The patent extracts the magazine follower mechanism from its normal function of controlling ammunition consumption and repurposes it to enable continuous firing. The follower is modified to remain engaged with the slide blocker even when the magazine is empty, preventing the slide from locking back and allowing continuous operation of the training firearm.
Solution Approach 2:
The patent introduces a slide blocker as an intermediary component between the magazine follower and the slide. This blocker acts as a mediator that translates the follower's position into a mechanical signal that prevents slide lockback, enabling continuous firing while maintaining the appearance of realistic magazine operation.
2Loss of information
If the slide mechanism is used to indicate magazine status, then ammunition status is clearly communicated, but frequent reloading interruptions occur
Solution Approach 1:
The patent creates a simulated copy of the ammunition presence by using the magazine follower to mechanically indicate magazine status through the slide blocker system. This copy allows the slide to continue cycling without actual ammunition, maintaining the visual and mechanical appearance of loaded ammunition while enabling continuous training fire.
3Object-affected harmful factors
If laser simulation is used for training, then safety is improved by eliminating live ammunition, but realism is reduced by preventing continuous firing
Solution Approach 1:
The patent replaces the mechanical ammunition feeding system with a laser simulation system while maintaining the mechanical appearance of realistic firearm operation. The laser module emits light pulses synchronized with the slide cycling, creating a visual simulation of bullet trajectory and impact without the hazards of live ammunition, while the modified magazine mechanism enables continuous operation.

AI summary
A firearm training barrel for a replica gun, the gun having a slide and a magazine with a follower. The barrel includes an extended or extendable member positioned or positionable to simulate the presence of one or more pellets in the magazine, whereby the replica gun can be fired even after the magazine's follower has reached the top of the magazine.
