Solution Overview

Problem

Existing cable management systems for firearm accessories lack features such as toolless installation, secure mounting without cables, and the ability to route cables in multiple orientations, while being compact, lightweight, and modular.

Innovation Solution

A cable management system comprising a cap with locking members and a plug featuring a tapered profile, allowing tool-free attachment to a firearm handguard, with crush-ribs to prevent slippage and multiple cable routing options, including 90-degree angles and simultaneous routing of multiple cables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional cable management methods (tape, zip ties, rerouting) are used, then cables can be secured, but the security and integrity of the cables are compromised and installation requires tools or complex procedures

Engineering Contradiction:

Improvecable securityVSAvoidinstallation ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The cable management system is divided into separate functional components: a cable retention member with locking features, a handguard with receiving structures, and a cable guide. This segmentation allows each component to be optimized independently while enabling toolless assembly through complementary interfaces.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cable retention member incorporates self-locking mechanisms where the cable itself engages with locking features through elastic deformation. The system performs its own securing function without requiring external tools or complex assembly procedures, achieving both reliability and ease of operation.

Inventive Principle:

Principle #25Self-service

2Reliability

If specialized cable management products are developed to improve cable security, then cable integrity is enhanced, but the systems become more complex and heavier

Engineering Contradiction:

Improvecable integrityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The cable retention member combines multiple functions into a single integrated component: cable guidance, cable retention through elastic locking, and positioning on the handguard. This merging reduces the number of separate parts and simplifies the overall system while maintaining cable integrity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The cable management system is designed to accommodate multiple cable types and routing configurations through universal interfaces and adjustable features. The retention member can secure cables in various orientations and the handguard receiving structures can be positioned at different locations, providing multi-functionality without increasing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If cable management systems are designed to secure multiple cables and provide multiple routing orientations, then versatility is improved, but the device size and weight increase

Engineering Contradiction:

Improverouting flexibilityVSAvoidassembly weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The cable guide incorporates three-dimensional routing capabilities with vertical and lateral guidance features. The retainer member includes angled surfaces and multi-directional locking features that enable cables to be routed in multiple orientations without requiring additional components, achieving versatility without weight penalty.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Strength

If cable management systems use metallic hardware for secure mounting, then mounting strength is improved, but the weight burden increases

Engineering Contradiction:

Improvemounting strengthVSAvoidassembly weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The system replaces traditional metallic mechanical fasteners with an elastic deformation locking mechanism. The retention member uses material elasticity to create secure engagement through friction and geometric interlocking, eliminating the need for metal screws or clips while maintaining mounting strength and reducing weight.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The cable retention member and handguard components are designed to work together as a composite system, where the interaction between different materials (such as polymer retention members with metal handguard slots) creates secure mounting without requiring heavy metallic hardware throughout the entire assembly.

Inventive Principle:

Principle #40Composite materials

AI summary

A cable management device having a cap with cable channels and an aperture through which a plug is removably coupled to secure the cable management device into an accessory mounting slot. The cable channels can be open on a bottom of the device to accept one or more cables and capture them between the cable management device and a surface of the object with the accessory slots. The cable management device enables toolless installation, secured mounting in the absence of a cable, cable routing in multiple orientations and the ability to hold more than one cable at a time.
