Solution Overview

Problem

Cables connecting remote switches to firearm accessories often become snagged or interfere with the operation of firearms and peripheral devices, necessitating a solution for effective cable management.

Innovation Solution

A cable management device comprising a body portion with a cable guide channel, an elongated threaded fastener with a conical head, and a pivot fastener that secures the device to a firearm's handguard, capturing and routing electrical cables while allowing flexible engagement and release.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cables are routed freely to connect remote switches to firearm accessories, then ease of operation is improved, but reliability deteriorates due to cables becoming snagged or interfering with firearm operation

Engineering Contradiction:
Improveease of cable connectionVSAvoidfirearm operation reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a cable management device as an intermediary component that mediates between the cable and the firearm operation. This device provides a dedicated routing path through the handguard, allowing cables to pass through safely without interfering with moving parts while maintaining connection ease. The cable guide channel and retention features create a controlled pathway that prevents the cable from becoming snagged or interfering with firearm operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If cables are secured tightly to prevent interference, then reliability is improved, but ease of operation deteriorates due to difficulty in cable release

Engineering Contradiction:
Improvecable securityVSAvoidcable release ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent employs dynamic retention features that adapt to cable insertion and removal actions. The spring-loaded retention arms or friction-based retention features provide secure holding during normal operation but automatically release when sufficient force is applied during cable removal. This dynamic behavior allows the system to maintain cable security during use while enabling easy cable release when needed.

Inventive Principle:
Principle #15Dynamics

3Reliability

If cable routing structure is made complex to prevent snagging, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvecable routing reliabilityVSAvoidcable management structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cable management device is designed to perform multiple functions within a single integrated component. It provides cable routing, cable retention, structural support, and interference prevention all through one device that attaches to the handguard. This multi-functionality reduces the need for separate components for each function, thereby managing complexity while achieving reliable cable routing and protection.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Reliability

If permanent cable securing is used to prevent interference, then reliability is improved, but adaptability deteriorates due to inability to easily remove or reposition

Engineering Contradiction:
Improvecable position stabilityVSAvoidcable management adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The retention features are designed with dynamic characteristics that allow them to transition between a secured state during operation and a released state for repositioning or removal. The spring mechanisms or friction-based retainers can be easily actuated to release the cable, allowing the user to reposition or remove the cable management device as needed, thereby providing adaptability while maintaining stability during use.

Inventive Principle:
Principle #15Dynamics

AI summary

Disclosed are implementations of a cable management device. An example cable management device can be attached to the handguard of a firearm, and used to route an electrical cable (or wire) connecting a remote switch to a firearm accessory, such as a flashlight. An example cable management device comprises: a body portion that includes a cable guide channel configured to receive therein a portion of an electrical cable; an elongated threaded fastener that includes a countersunk head; and a pivot fastener. The body portion is configured so that the countersunk head of the elongated threaded fastener can capture the portion of the electrical cable positioned within the cable guide channel. In some implementations, the body portion includes two cable guide channels, each of which is configured to receive therein a portion of an electrical cable.
