Solution Overview

Problem

Conventional rifle slings are often specific to particular firearms, fail to mount effectively on older rifles, and pose difficulties in assembly, especially in low-light or cramped conditions, and lack versatility in configuration and user preference adaptation.

Innovation Solution

A three-point weapon sling with side release buckles and a temperature-resistant strap, designed for universal compatibility with various firearm sizes and configurations, featuring adjustable length and non-reversible buckles for secure, quick orientation and multiple carry/shooting positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional slings are designed for specific firearms, then they provide secure mounting for particular weapons, but they lack versatility and require multiple slings for different firearms

Engineering Contradiction:

Improvecompatibility with different firearmsVSAvoidnumber of different slings required

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sling is designed with universal mounting hardware that can attach to various firearm types including rifles, shotguns, and pistols. The mounting system includes multiple attachment points and compatible hardware configurations that accommodate different firearm sizes and shapes, allowing one sling to serve multiple weapons rather than requiring separate slings for each firearm type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The sling system is divided into modular components including adjustable mounting hardware, segmented strap sections, and interchangeable attachment points. This segmentation allows the sling to be configured for different firearms and adjusted to various lengths and positions, providing versatility across multiple weapon types while maintaining secure mounting for each specific firearm.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If traditional buckles are used that allow insertion in either orientation, then assembly is simple, but the sling may twist and become difficult to re-orient for firing

Engineering Contradiction:

Improveassembly simplicityVSAvoidcorrect orientation assurance

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The buckle is designed with asymmetric features including a non-reversible insertion direction and orientation indicators such as molded arrows or asymmetric tooth patterns. This asymmetry ensures that the buckle can only be assembled in the correct orientation, preventing sling twisting while maintaining simple one-handed assembly. The asymmetric design provides visual and tactile feedback during assembly to confirm proper orientation without requiring complex manufacturing processes.

Inventive Principle:

Principle #4Asymmetry

3Adaptability or versatility

If the sling is made adjustable to different lengths, then it accommodates different user preferences and weapon sizes, but excess strap material may become tangled or interfere with weapon use

Engineering Contradiction:

Improveadjustability to user preferenceVSAvoidstrap tangling and interference

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The sling incorporates a dynamic adjustment mechanism with a ratchet or cam-based lock system that allows continuous length adjustment while preventing backward movement. This enables the user to precisely set the sling length to eliminate excess material that could tangle, while maintaining the ability to quickly re-adjust for different weapons or preferences. The dynamic locking mechanism ensures the strap remains taut and organized during weapon handling.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The sling length parameter can be continuously adjusted within a specific range to optimize performance for different users and weapons. By changing the effective length parameter through the adjustment mechanism, the sling eliminates excess material that causes tangling while maintaining sufficient length for proper weapon positioning and user comfort across various configurations.

Inventive Principle:

Principle #35Parameter changes

4Speed

If the sling assembly must be completed in darkness or cramped quarters, then rapid deployment is needed, but traditional buckles lack orientation guidance

Engineering Contradiction:

Improveassembly speedVSAvoidorientation identification

Core Design Contradiction:

SpeedVSEase of operation

Solution Approach 1:

The buckle incorporates high-contrast color coding and reflective materials that provide visual orientation guidance in low-light conditions. The asymmetric teeth and insertion direction are highlighted with contrasting colors or phosphorescent markings that are easily distinguishable in darkness, allowing rapid correct assembly without visual inspection. This color and reflectivity enhancement maintains simple assembly while adding critical orientation identification capability.

Inventive Principle:

Principle #32Color changes
