Solution Overview

Problem

Existing sealing solutions for optical cable ports in housings are dependent on specific cable diameters, requiring multiple seals for varying diameters, and manual compression can degrade signal quality due to local stresses.

Innovation Solution

A modular sealing gasket with a deformable body comprising a base, collar, and corrugated tube, allowing radial expansion and contraction to accommodate different cable diameters without manual adjustment, ensuring reliable sealing and signal integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple seals are used to accommodate different cable diameters, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improveadaptability to different cable diametersVSAvoidnumber of seals required

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sealing gasket is designed as a universal component that can accommodate multiple cable diameters through its deformable body with varying wall thicknesses. The gasket performs multiple functions: sealing different diameter cables, providing mechanical support, and absorbing compression forces, all within a single component structure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The sealing gasket incorporates a deformable body that can dynamically adapt its shape and internal diameter to match different cable sizes. The variable wall thickness allows the gasket to flex and deform radially, creating a dynamic sealing solution rather than a static fixed-diameter seal.

Inventive Principle:

Principle #15Dynamics

2Reliability

If manual compression is applied to ensure sealing quality, then sealing reliability is improved, but signal quality deteriorates due to local stresses

Engineering Contradiction:

Improvesealing qualityVSAvoidsignal quality degradation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The gasket design changes the physical parameters of the sealing interface by using variable wall thickness to distribute compression forces. Instead of uniform compression that creates stress concentrations, the gasket modifies the compression parameter distribution to be more uniform across the cable surface, protecting signal integrity.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The gasket converts the potentially harmful concentrated compression forces into beneficial distributed pressure. The variable wall thickness acts as a stress-distributing mechanism that transforms localized high-stress points into a uniform pressure distribution, turning what would be a harmful effect into a beneficial sealing mechanism.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Device complexity

If a single seal is used to cover different cable diameters, then device complexity is reduced, but adaptability deteriorates

Engineering Contradiction:

Improvenumber of seals requiredVSAvoidrange of cable diameters accommodated

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The gasket applies the local quality principle by having different wall thicknesses in different radial zones. The thicker sections provide structural support and sealing for larger diameters, while thinner sections allow greater deformation for smaller cables, enabling a single gasket to adapt to various cable sizes through localized structural variations.

Inventive Principle:

Principle #3Local quality
