Solution Overview

Problem

Existing combs used to guide and hold optical or electrical cables in distribution boxes often damage the cables and fail to adapt to varying cable sizes effectively.

Innovation Solution

A comb with a rectangular base and deformable channels, made from a combination of rigid and flexible materials, featuring bosses for secure cable retention, allowing for various cable diameters and multiple levels without damaging the cables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If rigid combs are used to hold cables, then structural strength is improved, but cable damage occurs

Engineering Contradiction:
Improvestructural strengthVSAvoidcable damage
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent applies this principle by using a flexible retaining structure made of elastomeric material that forms channels to hold cables. The flexible material conforms to the cable shape and provides gentle retention without rigid edges that could damage the cable, while still maintaining structural integrity through the combination with the rigid support.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent applies this principle by combining two different materials: a rigid support structure (injection-molded plastic or metal) that provides overall strength and shape, and a flexible retaining structure (elastomeric material) that contacts the cables. This composite approach allows the system to simultaneously achieve structural strength and cable protection.

Inventive Principle:
Principle #40Composite materials

2Manufacturing precision

If combs are designed for specific cable sizes, then retention precision is improved, but adaptability to different cable diameters deteriorates

Engineering Contradiction:
Improveretention precisionVSAvoidadaptability to different cable diameters
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies this principle by making the retaining structure flexible rather than rigid. The elastomeric material can dynamically adjust its shape and pressure to accommodate cables of varying diameters while maintaining secure retention. This dynamic adaptability allows a single comb design to work with multiple cable sizes without requiring precise pre-matching.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies this principle by allowing the retaining structure to change its physical parameters (shape, pressure, conformality) in response to different cable diameters. The flexible material deforms to match the cable dimensions, providing precise retention for each specific cable while maintaining the same overall channel structure.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If multiple cables are held in the same channel, then device complexity is reduced, but cable retention reliability deteriorates

Engineering Contradiction:
Improvedevice complexityVSAvoidcable retention reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent applies this principle by dividing the support structure into multiple separate channels, each capable of holding one or more cables. This segmentation allows each channel to provide dedicated retention for its cables while the overall comb structure remains relatively simple. The flexible retaining structure within each channel can independently adapt to the cables it holds.

Inventive Principle:
Principle #1Segmentation
