Shoulder Sling With Cam Lock Buckle and Quick-Release Coupler
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior shoulder slings are uncomfortable, cause shoulder pain, and lack adjustability and functionality, making it difficult to maintain optimal positioning of carried items like rifles or other implements.
Innovation Solution
A sling system with an adjustable strap and handle system, featuring a cam lock buckle and quick attachment coupler with a sliding pin mechanism for easy attachment and detachment, allowing for comfortable and secure carrying of items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If prior art slings use durable but inflexible straps with padding, then strength and durability are improved, but comfort and shoulder fatigue are worsened
Solution Approach 1:
The patent replaces rigid padded straps with a flexible rubber hose that can conform to the user's shoulder contour. The rubber hose is covered with a non-slip material that provides grip without rigid padding, allowing the sling to adapt to body shape while maintaining durability and preventing shoulder pain through flexibility rather than rigid support.
2Ease of operation
If prior art slings have fixed or single adjustment location, then device complexity is reduced, but ease of operation and optimal positioning are worsened
Solution Approach 1:
The patent implements a dynamic adjustment system with multiple adjustment locations along the sling strap, allowing users to modify the sling length and positioning at various points. This includes a quick-release mechanism that enables easy adjustment while wearing the sling, providing adaptability without requiring complex multi-component adjustment systems.
3Strength
If prior art slings use screw-type pin coupling, then connection strength is improved, but ease of operation and attachment speed are worsened
Solution Approach 1:
The patent extracts the threading mechanism from the coupling system, replacing the screw-type pin with a simple friction-fit or snap-fit mechanism. The coupling uses a tapered bore and corresponding tapered pin or insert that achieves strong connection through geometric interference rather than threaded fastening, enabling quick attachment and detachment without time-consuming screwing operations.
4Ease of operation
If prior art slings lack handle or grip mechanism, then device complexity is reduced, but ease of operation and control are worsened
Solution Approach 1:
The patent merges the handle function into the existing strap structure by adding a loop or grip element that can be integrated with the adjustment mechanism. This combination allows users to grip and manipulate the sling for positioning and adjustment without adding separate complex handle assemblies, maintaining simplicity while improving ease of operation.

AI summary
The present relates to a sling system, and more specifically, to a sling system which may be used for shoulder mounted sling requirements, such as for rifles, archery bows, crossbows, weed eaters and metal detectors, to name a few. The sling system includes a shoulder portion with a plurality of columns of slot apertures with each column offset from the adjacent column, an adjustable position handle and couplers on each end of the sling system to couple it to the desired implement or object.
