Solution Overview

Problem

Conventional weapon slings are inadequate for military personnel as they restrict flexibility, cause fatigue, and risk weapon damage during athletic activities, and are inefficient for switching between weapons.

Innovation Solution

A wearable weapon restraint system featuring a retractable cable reel with adjustable tension, a conduit for cable routing, and a supplemental magnet-based restraint device that allows for secure carrying and quick access to the weapon.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional sling is used to retain the weapon, then weapon retention is adequate, but user flexibility is restricted and fatigue increases

Engineering Contradiction:
Improveweapon retentionVSAvoiduser flexibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies the dynamics principle by transitioning from a static conventional sling to a dynamic retractable cable system. The cable can extend and retract based on user movement, allowing the weapon to move freely during athletic activities while maintaining retention when needed. The spring mechanism automatically adjusts cable length, providing both security and flexibility without requiring manual intervention.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the restraint system into multiple independent components: a retractable cable mechanism, a conventional sling component, and a supplemental magnet-based restraint device. This segmentation allows each component to perform its specific function optimally - the cable provides dynamic adjustment, the sling ensures baseline retention, and the magnet device offers additional stabilization when needed.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a conventional sling is used to carry the weapon, then the weapon can be carried, but weight concentrates on the user's body causing fatigue

Engineering Contradiction:
Improveweapon carrying capabilityVSAvoiduser fatigue
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The patent implements the anti-weight principle through the spring mechanism in the retractable cable system. The spring acts as a counterweight mechanism that offsets the gravitational force on the weapon, distributing the weight between the spring's elastic potential energy and the user's body. This reduces the effective weight the user must support continuously, thereby reducing fatigue during extended use.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

3Reliability

If a conventional sling is used, then the weapon can be retained, but switching between weapons is inefficient and time-consuming

Engineering Contradiction:
Improveweapon retentionVSAvoidweapon switching time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by having the retractable cable system pre-positioned and ready for rapid deployment. When switching weapons, the user simply releases the fastening device and attaches a new weapon to the already-positioned cable system, eliminating the need to reposition or reconfigure the restraint system. The supplemental magnet device also provides preliminary stabilization, allowing quick weapon changes without compromising retention.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If a conventional sling is used during athletic activities, then the weapon can be carried, but the weapon may contact the ground causing damage or malfunction

Engineering Contradiction:
Improveweapon carryingVSAvoidweapon damage risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses the dynamics principle to allow the cable system to dynamically adjust its length during athletic activities. As the user moves, the cable extends and retracts accordingly, maintaining optimal tension and positioning the weapon away from the ground. This dynamic adjustment prevents the weapon from contacting the ground during running, jumping, or other athletic movements while maintaining secure carrying.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements beforehand cushioning through the supplemental magnet-based restraint device that can be activated before potential ground contact occurs. The magnet device provides an additional restraint layer that prevents the weapon from reaching positions where it could contact the ground, cushioning against potential damage before it happens.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enhances user flexibility and reduces fatigue by evenly distributing the weight of the weapon, preventing damage, and enabling rapid switching between weapons without the need for manual repositioning.

Implementation Method 1

The retractable cable reel may include a spring that maintains tension on the cable

Methodology Applied
Scientific EffectSpring: Spring

Implementation Method 2

The supplemental restraint device can include a strap having at least one magnet. When the magnet is coupled to a magnetic object, the strap can form a loop that supports a portion of the weapon

AI summary

A wearable weapon restraint system is provided. The system includes a cable having a proximal end and a distal end, a retractable cable reel configured to contain the cable and allow the cable to extend and/or retract relative to the retractable cable reel, and a conduit having a passageway extending along at least a portion of the conduit. The cable can be positioned such that at least a portion of the cable passes through the passageway of the conduit. The distal end of the cable can be coupled to a fastening device.
