Solution Overview

Problem

Current computer simulations of reloading a magazine for hand-operated devices lack realism, as they either require user button presses or lack the physical interaction of ejecting and re-engaging a magazine, diverging from the actual experience.

Innovation Solution

A system that includes a magazine retention mechanism with external or internal interference flanges and sensors to simulate the physical act of ejecting and re-engaging a magazine, allowing the simulation to register the magazine's state and provide a more realistic reloading experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a button press or automatic reload is used in simulation, then the simulation is simple to operate, but the realism of the reloading experience is reduced

Engineering Contradiction:
Improvesimplicity of reload operationVSAvoidrealism of reloading experience
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent creates a physical copy of the magazine that can be ejected and reinserted into the hand-operated device. This physical magazine copy allows users to perform actual reloading actions (ejection and reinsertion) while the simulation software tracks these actions through sensors, thereby maintaining both operational simplicity and realism simultaneously.

Inventive Principle:
Principle #26Copying

2Reliability

If a physical magazine ejection and reinsertion system is implemented, then the realism of the reloading experience is improved, but the device complexity increases

Engineering Contradiction:
Improverealism of reloading experienceVSAvoidcomplexity of magazine retention system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical sensor systems with magnetic sensors that detect the presence or absence of the magazine through non-contact means. This substitution reduces mechanical complexity while maintaining the ability to track magazine ejection and reinsertion actions for simulation realism.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magazine retention mechanism serves multiple functions: it physically holds the magazine in place during operation, enables controlled ejection for reload simulation, and works in conjunction with magnetic sensors to detect magazine presence. This multi-functionality reduces the need for separate systems for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If magnetic sensors are used to detect magazine presence, then the measurement of magazine state is accurate, but the device complexity increases

Engineering Contradiction:
Improveaccuracy of magazine state detectionVSAvoidcomplexity of sensor system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical contact sensors with magnetic sensors that detect magazine presence through non-contact means. This substitution reduces mechanical complexity while maintaining the ability to track magazine ejection and reinsertion actions for simulation realism.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A system that enables a user to simulate the reloading of a magazine fed hand operated device used in a simulation. The user may eject the physical magazine using the magazine ejection button on the hand operated device, and then engage that same magazine which has been stopped from being fully ejected from the hand operated device's magazine housing by a magazine retention mechanism. An internal magazine engagement sensor registers with the simulation that the magazine has been ejected by the user and then has been re-engaged when the magazine is fed back into the housing and locked in by the hand operated device's locking mechanism.
