Solution Overview

Problem

Conventional firearm rails are difficult to securely and quickly attach and detach without modifying the firearm, especially in combat situations, and often require tools, which can lead to lost components and accuracy issues.

Innovation Solution

A removably attachable accessory rail kit with self-retaining fasteners and a stabilizer arm that engages the firearm without tools, allowing for tool-free mounting and dismounting, providing stability and shock absorption without modifying the firearm.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional rails are securely attached to the firearm using mounting screws and modified firearm, then stability and reliability are improved, but the complexity of attachment and need for tools increases

Engineering Contradiction:
Improveattachment stabilityVSAvoidattachment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The rail attachment system is divided into multiple engagement points (front structural support at first point, back structural support at second point, side rail support at third point, and stabilizer arm at fourth point) that work together to provide secure attachment without requiring complex tool-based fastening systems

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rail kit is designed to attach and detach itself without external tools through self-retaining fasteners and engagement mechanisms that automatically secure the rail to the firearm at multiple points, eliminating the need for screwdrivers or other tools

Inventive Principle:
Principle #25Self-service

2Reliability

If conventional rails require tools for assembly and use screws, then secure attachment is achieved, but components can become lost and accuracy may be affected

Engineering Contradiction:
Improveattachment securityVSAvoidcomponent loss
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The attachment mechanism merges the fastening function into the structural supports themselves, where the front structural support, back structural support, side rail support, and stabilizer arm all integrate retention features that prevent component loss while securing the rail

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Self-retaining fasteners act as intermediaries between the structural supports and the firearm, providing secure attachment without requiring separate screws that could become lost, as the fasteners are retained within the engagement points

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the rail is modified to accommodate mounting screws, then stable attachment is achieved, but the firearm performance may be affected

Engineering Contradiction:
Improveattachment stabilityVSAvoidfirearm performance degradation
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The attachment system extracts the modification requirement from the firearm by using engagement points that work with the existing firearm structure without requiring drilling holes in the barrel or other permanent modifications that could affect firearm performance

Inventive Principle:
Principle #2Taking out (Extraction)

4Reliability

If conventional rails have many different components, then attachment security is improved, but attaching and detaching becomes burdensome in the field

Engineering Contradiction:
Improveattachment securityVSAvoidfield attachment ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The attachment system incorporates dynamic self-retaining fasteners that can be quickly engaged and disengaged without tools, allowing the rail to be securely attached when needed and easily removed when required, adapting to the operational needs in the field

Inventive Principle:
Principle #15Dynamics

AI summary

An accessory rail kit removably mountable on a weapon. The accessory rail kit includes an upper accessory rail extending parallel to a round of the weapon. The upper accessory rail has a front end, a back end, and an upper accessory mounting surface. A base supports the upper accessory rail. A front structural support extends downwardly from the base, proximate to the front end of the upper accessory rail, and engages the weapon. A back structural support extends downwardly from the base, proximate to the back end of the upper accessory rail, and engages the weapon. A side rail support extends downwardly from a right side of the base that engages the weapon. A stabilizer arm extends downwardly from a left side of the base, with a contoured foot attached to a lower end of the stabilizer arm, and engages the weapon.
