Solution Overview

Problem

Current tool-based compression mechanisms for gel or gel-like sealing elements in telecommunications closures are cumbersome and increase installation time, requiring tools like screwdrivers, which complicates the installation process.

Innovation Solution

A toolless compression mechanism comprising an upper compression element with wings, an intermediate compression element, and a lower compression segment, where the upper compression element displaces along a hub extension to compress a sealing element, allowing for compression without tools, with thread pitch optimized for efficient sealing in less than one turn.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If tool-based compression mechanisms are used to compress gel sealing elements, then effective compression is achieved, but installation time increases and installation complexity increases

Engineering Contradiction:
Improvesealing effectivenessVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The compression mechanism is designed to be self-contained with integrated compression elements that automatically compress the gel sealing element when the closure components are assembled. The mechanism uses the assembly process itself to generate the compression force, eliminating the need for separate tool-based compression steps and reducing installation time while maintaining sealing effectiveness.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The compression mechanism is divided into multiple functional segments including compression elements, sealing elements, and structural components that work together. This segmentation allows each component to perform its specific function efficiently, with the compression elements directly contacting and compressing the gel sealing element during assembly, thereby reducing installation time without compromising seal integrity.

Inventive Principle:
Principle #1Segmentation

2Reliability

If tool-based compression mechanisms are used to compress gel sealing elements, then effective compression is achieved, but installation complexity increases

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

Solution Approach 1:

The compression function is merged into the closure assembly structure itself. The compression elements are integrated with the closure components, and the assembly process simultaneously achieves both closure formation and sealing element compression. This merging eliminates the need for separate tools and steps, reducing installation complexity while ensuring effective compression for reliable sealing.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The closure mechanism is designed to perform its own compression function during assembly. The structural components of the closure generate the necessary compression force on the gel sealing element automatically when assembled, making the system self-sufficient and eliminating the need for external tools or complex installation procedures.

Inventive Principle:
Principle #25Self-service

3Reliability

If gel sealing elements are compressed to increase effective sealing area, then sealing effectiveness improves, but compression mechanism complexity increases

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The compression elements are designed with localized compression zones that apply force precisely where needed on the gel sealing element. This localized approach increases the effective sealing area at critical points without requiring complex overall compression mechanisms, maintaining simplicity while improving sealing effectiveness through targeted compression.

Inventive Principle:
Principle #3Local quality

AI summary

A toolless compression mechanism includes an upper compression element having a plurality of wings surrounding a hub, a base having a locator element positioned on an underside surface of the base, and a hub extension having inner threads disposed therein; an intermediate compression element having an upper intermediate compression surface having a channel that upon assembly of the toolless compression mechanism mates with upper compression element; a lower compression segment having an extension with threads that mates with the inner threads of the upper compression element, and a sealing element positioned between the intermediate compression element and the lower compression segment. When turned, the upper compression element is displaced along the hub extension such that the sealing element is compressed.
