Solution Overview

Problem

Existing cable port entry devices have limitations in accommodating cables of different sizes, often requiring multiple sealing elements or tear-out sections, which increases costs and complexity, and fail to provide an effective seal for both small and large cables.

Innovation Solution

The development of universal cable port entry devices with compressible members, including foam materials, that adapt to various cable sizes through unique geometries and deformable fingers, ensuring proper positioning and sealing, regardless of the number or size of cables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If round cutouts are provided in cable sealing devices, then cables can be received, but the devices have limited ability to accommodate cables of different sizes

Engineering Contradiction:
Improvecable size accommodationVSAvoidsealing structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by making the cutout shape variable through compression. The compressible member changes the geometric parameters of the cutout from a fixed round shape to a variable shape that adapts to different cable diameters. When compressed, the cutout deforms to match the cable size, enabling a single device to accommodate multiple cable sizes without increasing structural complexity.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements dynamics by introducing a compressible member that allows the cutout to dynamically change its shape and size. Instead of a static round cutout, the compression mechanism enables the cutout to transform into different configurations based on the cable being inserted, providing adaptability while maintaining a simple single-piece structure.

Inventive Principle:
Principle #15Dynamics

2Reliability

If multiple sealing elements or tear-out sections are used to accommodate different cable sizes, then cable positioning and sealing improve, but costs and installation complexity increase

Engineering Contradiction:
Improvesealing effectivenessVSAvoidnumber of sealing elements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple sealing elements into a single integrated compressible member. Instead of using separate sealing components or tear-out sections, the compression mechanism consolidates all sealing functions into one piece that adapts to different cable sizes, reducing the number of parts while maintaining or improving sealing effectiveness.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The compressible member serves multiple functions simultaneously: it provides sealing, cable positioning, and size adaptation all in one component. This universal element replaces what would traditionally require multiple specialized components, reducing device complexity while ensuring reliable sealing across different cable configurations.

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

3Adaptability or versatility

If round cutouts are made large enough for small cables, then small cables can be received, but large cables can also be accommodated, however small cables shift within the cutout preventing effective sealing

Engineering Contradiction:
Improvecable size rangeVSAvoidsealing tightness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent uses parameter changes to dynamically adjust the cutout dimensions to match the cable size. When a small cable is inserted, the compressible member maintains a tighter fit by deforming the cutout boundaries, preventing cable shift. The geometric parameters of the cutout change based on compression, ensuring optimal sealing contact regardless of cable diameter.

Inventive Principle:
Principle #35Parameter changes

AI summary

A system for sealing cable(s) is provided comprising a first compressible member defining a wall portion and a first groove having a first rounded portion and a first straight portion. A minimum depth of the first rounded portion is less than a depth of the first straight portion, and the depth of the first straight portion is less than a depth of the wall portion. The first compressible member is configured to receive a first cable of the cable(s) in the first groove. The system comprises a second compressible member comprising fingers attached together on one side of the second compressible member. Cuts are formed in the second compressible member, and a respective cut is positioned between adjacent fingers. At least one finger deforms as the second compressible member is compressed, and the fingers at least partially restrict movement of and form a seal around the first cable.
