Firearm Simulator Pressure Accumulator for Realistic Recoil
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weapon simulators for training purposes fail to realistically simulate the behavior of real firearms, particularly in scenarios where a magazine is removed or reinserted, as they do not accurately replicate the ability to fire a remaining cartridge or require repeated magazine insertion for each shot, and they lack efficient recoil simulation mechanisms.
Innovation Solution
The implementation of an internal pressure accumulator within the firearm's hydraulic device, connected to a converted magazine with an external compressed air reservoir, which allows for continued recoil simulation after the magazine is removed by storing enough compressed air to actuate the breech at least once more, and includes an electromagnetic valve for controlled air supply and a pressure reducer to manage high pressures, along with an electronic storage element for shot counting and magazine intelligence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If an external compressed air reservoir is used to supply the hydraulic device, then the firearm can be refilled for continued use, but the firearm requires repeated magazine insertion for each shot which reduces operational realism
Solution Approach 1:
The patent implements an internal pressure accumulator that is pre-filled with compressed air before the magazine is removed. This preliminary action ensures that sufficient pressure remains in the hydraulic device to enable at least one additional shot after magazine removal, eliminating the need for repeated magazine insertions and maintaining operational realism.
2Productivity
If compressed air is supplied continuously to the hydraulic device, then the breech can be actuated repeatedly, but compressed air escapes when the magazine is removed which wastes the hydraulic medium
Solution Approach 1:
The patent introduces a non-return valve as an intermediary component between the internal pressure accumulator and the hydraulic connection. This valve allows compressed air to flow from the accumulator to the hydraulic device during firing but prevents backward flow and escape when the magazine is removed, thus eliminating waste of the hydraulic medium while maintaining continuous shot capability.
3Force
If high pressure compressed air is used to simulate recoil realistically, then the recoil simulation is accurate, but the system becomes dangerous and requires complex pressure management
Solution Approach 1:
The patent implements a pressure reducer that automatically regulates the high pressure compressed air from the external reservoir to a safe operating level for the hydraulic device. This self-regulating mechanism maintains realistic recoil force while inherently managing pressure safety, reducing the need for complex external pressure management systems.
