Firearm Barrel Thrust Rod for Realistic Slide Cycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional simulated firearms fail to replicate the unique characteristics of actual firearms, such as trigger mechanics and recoil, during practice firing simulations, reducing their effectiveness and safety.
Innovation Solution
A moving cylinder with a thrust rod is positioned within the firearm's barrel, triggered by compressed air or CO2, to mimic the action of a cartridge, moving the slide and simulating the recoil and reset of a real firearm, allowing for realistic practice without live ammunition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional simulated weapons are used during practice firing simulations, then safety is improved and economy is maintained, but the unique characteristics of actual firearms (trigger slack, pressure, travel distance, reset) cannot be replicated, reducing training effectiveness
Solution Approach 1:
The patent creates a physical copy of a cartridge inside the barrel (moving cylinder with thrust rod) that replicates the functional characteristics of an actual cartridge without using live ammunition. This copy reproduces the trigger pull characteristics, slide movement, and recoil spring compression, allowing realistic practice while maintaining safety through the use of inert components
Solution Approach 2:
The moving cylinder with thrust rod acts as an intermediary between the trigger mechanism and the slide. When the trigger is pulled, the thrust rod is driven forward by compressed air or CO2, pushing the slide rearward to replicate the firing cycle. This intermediary mechanism transfers the trigger action through realistic mechanical movement without involving actual ammunition
2Reliability
If unloaded firearms are used during simulations, then safety is improved, but the firing cycle does not cycle normally to reset the trigger, reducing training effectiveness
Solution Approach 1:
The system uses the firearm's own recoil spring and slide mechanism to automatically reset the trigger after each simulated shot. When the thrust rod pushes the slide rearward, the recoil spring compresses and then returns the slide to its forward position, which naturally resets the trigger for the next shot. This self-service mechanism replicates the normal firing cycle without requiring manual intervention
Solution Approach 2:
The patent introduces dynamic movement to the simulated cartridge through the moving cylinder and thrust rod assembly. The thrust rod is driven forward by compressed gas, pushing the slide rearward in a dynamic motion that mimics the recoil of an actual firearm. This dynamic action enables the slide and trigger to cycle naturally, providing realistic training experience
3Manufacturing precision
If a moving cylinder with thrust rod is positioned within the barrel to simulate cartridge action, then realistic practice firing is enabled, but device complexity increases
Solution Approach 1:
The moving cylinder with thrust rod is nested inside the existing barrel structure, utilizing the barrel's internal space. The breach nut and barrel nut are positioned at the ends of the barrel, with the moving cylinder fitting between them. This nested arrangement incorporates the simulation mechanism within the firearm's existing geometry, minimizing external additions and reducing overall system complexity
Solution Approach 2:
The patent uses compressed air or CO2 cartridges to drive the thrust rod forward, replacing complex mechanical firing mechanisms. The pneumatic or gas-powered actuation simplifies the moving cylinder assembly by eliminating the need for springs, weights, or complex linkages, reducing the number of parts while achieving realistic slide movement and recoil simulation
