Solution Overview

Problem

Existing inline cable sleeves do not provide sufficient sealing for communication cables, particularly at cable entry points, which can lead to interruptions and signal loss in communication networks.

Innovation Solution

The inline cable sleeve features compressible and/or deformable sealing elements positioned between differently contoured walls, ensuring improved sealing by allowing defined drainage of these elements when compressed or deformed, and utilizing adapter pieces and pressure pieces with spike-like projections for optimal cable support and strain relief.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional sealing structures are used in inline cable sleeves, then the structure remains simple, but the sealing effectiveness at cable entry points is insufficient

Engineering Contradiction:
Improvesealing effectivenessVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a compressible sealing element made of flexible material that deforms to conform to the cable surface, creating an effective seal. The sealing element is positioned between differently contoured walls that guide its deformation, ensuring reliable sealing without complex mechanical structures

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The sealing element changes its physical parameters (shape, volume, density) through compression and deformation when cables are inserted. The differently contoured walls create varying compression zones that adapt the sealing element's parameters to match different cable diameters, achieving universal sealing effectiveness

Inventive Principle:
Principle #35Parameter changes

2Reliability

If sealing elements are compressed to improve sealing, then sealing effectiveness increases, but the sealing elements may drain or deform uncontrollably

Engineering Contradiction:
Improvesealing effectivenessVSAvoidsealing element stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent uses differently contoured walls with asymmetric geometry - one wall has a first contour while the opposing wall has a second contour. This asymmetry creates a controlled deformation path for the sealing element, ensuring it drains or deforms in a predetermined direction rather than uncontrollably

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The differently contoured walls act as intermediaries that mediate the compression and deformation of the sealing element. They guide the sealing element's transformation from its initial state to its compressed sealing state, preventing uncontrolled drainage while maintaining stability

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the cable sleeve is designed to accommodate various cable diameters, then adaptability increases, but sealing precision decreases

Engineering Contradiction:
Improvecable diameter adaptabilityVSAvoidsealing precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent creates different local conditions within the sealing area through differently contoured walls. Each region between the walls provides specific compression characteristics tailored to different cable sizes, allowing the same sealing structure to achieve precise sealing for various cable diameters through localized deformation control

Inventive Principle:
Principle #3Local quality
