Solution Overview

Problem

Firearm suppressors fail to completely dampen sound, light, and heat effects during discharge, posing risks to operators and others due to residual vibrational, acoustical, and thermal signatures that can be detected, and often cause burns from direct contact with hot suppressor surfaces.

Innovation Solution

An adjustable sound, light, and heat shield configured to mount on a firearm suppressor, featuring a proximal and distal enclosure with tapered structures and fluidic channels to disperse residual effects, and a compression sleeve with a spring and alignment partition to secure the suppressor, reducing detectable noise, light, and heat emissions while preventing direct heat transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a firearm suppressor is used to dampen sound, light, and heat effects, then the audible noise is reduced to safer levels, but residual vibrational soundwaves and heat signatures remain detectable and can cause burns from direct contact

Engineering Contradiction:
Improveaudible noise levelVSAvoidresidual vibrational soundwaves and heat signatures
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The shield is configured to surround the suppressor, creating a nested structure where the suppressor is positioned within the enclosed space of the shield. This nesting arrangement allows the shield to capture and contain the residual vibrational soundwaves and heat signatures generated by the suppressor, preventing them from radiating into the external environment while maintaining the suppressor's primary noise-dampening function

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The shield acts as an intermediary barrier between the suppressor and the external environment. It intercepts the residual vibrational soundwaves and heat signatures before they can escape, serving as a mediating structure that protects operators and bystanders from these harmful residual effects while allowing the suppressor to continue its sound-dampening operation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Illumination intensity

If the suppressor is designed to absorb and retain heat, then muzzle flash is reduced, but the suppressor surface becomes dangerously hot causing burns from accidental contact

Engineering Contradiction:
Improvemuzzle flash intensityVSAvoidsuppressor surface temperature
Core Design Contradiction:
Illumination intensityVSTemperature

Solution Approach 1:

The shield serves as a thermal intermediary that absorbs and contains the heat generated by the suppressor during operation. By positioning the shield between the hot suppressor surface and the external environment, it prevents direct contact between operators and the dangerously hot suppressor, reducing the risk of burns while maintaining the heat-absorbing function that suppresses muzzle flash

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The shield creates a protective thermal barrier that isolates the hot suppressor from direct contact. This barrier function allows the suppressor to retain the heat necessary for muzzle flash suppression while preventing that same heat from causing burns to operators who may accidentally contact the suppressor during handling

Inventive Principle:
Principle #30Flexible shells and thin films

3Object-affected harmful factors

If the suppressor captures and holds expanding blast gases, then sound is dampened, but the suppressor body becomes heated to dangerous levels

Engineering Contradiction:
Improvesound wave propagationVSAvoidsuppressor body temperature
Core Design Contradiction:
Object-affected harmful factorsVSTemperature

Solution Approach 1:

The shield surrounds the suppressor in a nested configuration, creating an additional enclosed space that captures and contains the hot blast gases as they expand within the suppressor. This nested structure allows the suppressor to continue capturing blast gases for sound dampening while the shield contains the resulting heat, preventing it from radiating externally and causing dangerous temperature increases

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A universal firearm shield adapted to attach to a firearm suppressor. Suppressors fail to dampen all of the effects of firearm discharge, leaving behind residual effects that may be noticeable. The shield dampens the residual effects of firearm discharge that are not captured by the suppressor. The residual effects are captured by the shield and dispersed throughout one or more interior chambers. The shield easily, quickly, and securely couples to suppressors of varying geometries due to the slidably adjustable components of the shield. The shield is configured to surround the suppressor and axially align with the suppressor. As such, the muzzle of the firearm axially aligns with the shield, the suppressor, and the barrel for an unobstructed projectile path during discharge.
