Solution Overview

Problem

Existing arm braces for firearms are rigid and do not collapse, making them cumbersome for transport and storage.

Innovation Solution

A collapsible arm brace apparatus with a hinge mechanism that allows the brace to pivot from a deployed shooting position to a stowed position, reducing the overall size for easier handling and storage, and includes a strap and buckle for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the arm brace is designed with a rigid structure to provide stability during shooting, then the shooting stability is improved, but the ease of transport and storage deteriorates due to increased size

Engineering Contradiction:
Improveshooting stabilityVSAvoidease of transport
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The arm brace transitions from a static rigid structure to a dynamic collapsible structure. The hinge mechanism allows the arm brace to change its configuration between a deployed shooting position providing stability and a collapsed storage position reducing size for easy transport, directly resolving the contradiction between stability and portability

Inventive Principle:
Principle #15Dynamics

2Reliability

If the arm brace is designed with a rigid structure to maintain functional position during use, then the functional performance is improved, but the volume increases making storage difficult

Engineering Contradiction:
Improvefunctional performanceVSAvoidbrace volume
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The arm brace is divided into multiple segments connected by hinges, allowing it to be collapsed into a compact form for storage while maintaining its full functional dimensions when deployed for shooting, effectively reducing the volume during non-use without compromising functional performance

AI summary

An arm brace apparatus for use with a firearm allows for a reduced form factor when the arm brace is not needed by the shooter. The arm brace apparatus includes a hinge which allows for a substantial portion of the brace to pivot between an open or deployed configuration, a useful position when shooting, and a closed or stowed position, useful for transportation or storage of the firearm to which the arm brace is attached. A latch mechanism allows the device to be locked in either the open or closed position.
