Solution Overview

Problem

Existing noise generation devices are large, cumbersome, and lack portability, failing to simulate realistic gun noises effectively, especially when synchronized with gun firing or in rapid succession, and are not easily attachable to weapons.

Innovation Solution

A compact noise generation device with a movable chamber that injects combustible material, ignites it to produce an explosion, and exhausts gases quickly to mimic gun sounds, featuring a solenoid valve for controlled gas injection and a spring mechanism for rapid cycling, allowing for attachment to guns or operation as a standalone unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If prior art noise generation devices use external gas tanks with large hoses to supply combustible material, then they can generate loud noises, but they become large, cumbersome, and lack portability

Engineering Contradiction:
Improvenoise generation capabilityVSAvoiddevice portability
Core Design Contradiction:
Object-affected harmful factorsVSWeight of moving object

Solution Approach 1:

The patent integrates the gas reservoir directly into the device housing, combining the fuel storage and combustion functions into a single compact unit. This eliminates the need for separate external gas tanks and connecting hoses, thereby maintaining noise generation capability while dramatically improving portability and reducing device size.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The gas reservoir is nested within the device housing structure, with the combustible material stored in an internal chamber that is part of the overall device assembly. This nested arrangement allows the gas supply system to be compact and self-contained, eliminating external components and improving portability.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Object-affected harmful factors

If prior art devices are designed as standalone units with external gas supplies, then they can generate noise, but they cannot be easily attached to weapons or operated in synchronized firing scenarios

Engineering Contradiction:
Improvenoise generationVSAvoidweapon attachment capability
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The device is designed with a universal mounting interface that enables it to be attached to various weapon platforms while also functioning as a standalone unit. The compact self-contained design with integrated gas reservoir allows it to adapt to different operational scenarios, providing versatility in both attached and independent modes of operation.

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

3Object-affected harmful factors

If prior art noise devices use simple combustion chambers without rapid cycling mechanisms, then they can generate noise, but they cannot produce high repetition rates or low latency synchronized firing sounds

Engineering Contradiction:
Improvenoise outputVSAvoidfiring repetition rate
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The device incorporates a spring-loaded mechanism that enables rapid periodic cycling of the combustion chamber. The spring acts on a piston or valve system to quickly reset the chamber after each combustion event, allowing high repetition rates and enabling the device to produce synchronized firing sounds with low latency between successive noise generations.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The spring mechanism automatically resets the combustion chamber without requiring external intervention between firing cycles. The stored elastic energy in the spring provides the force needed to rapidly return the chamber to its initial state, enabling high-speed repeated operation and improving productivity through self-powered cycling.

Inventive Principle:
Principle #25Self-service
