Solution Overview

Problem

Enclosure assemblies for mounting connectors at varying depth positions face challenges in providing effective strain relief and sealing for long, thin optical fibers, which are prone to damage due to environmental factors and dimensional variations among different connectors and enclosures.

Innovation Solution

A kit comprising a sealing sub-assembly with an annular sealing element and washer, supported by a housing sub-assembly with a flange and an outer shell, allowing the connector to be adjusted to multiple retaining positions along the longitudinal direction, and featuring a telescoping sub-assembly with a retaining section and spring retainer for secure locking and sealing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed-position connector mounting is used, then the structural simplicity is maintained, but the adaptability to different connectors and enclosures is reduced

Engineering Contradiction:
Improveadaptability to different connectors and enclosuresVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connector mounting structure transitions from a fixed position to a telescoping mechanism that can dynamically adjust its position along the longitudinal direction, enabling the connector to be retained at multiple different positions while maintaining structural integration

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The enclosure assembly is designed with a universal mounting structure that can accommodate different types of connectors and enclosures through the telescoping mechanism, allowing a single design to serve multiple applications and configurations

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

2Adaptability or versatility

If the connector position is made adjustable to multiple retaining positions, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improvevariable position retentionVSAvoidhousing structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The telescoping sub-assembly is nested within the housing sub-assembly, with the telescoping section containing retaining sections that can lock at multiple positions, creating a compact multi-functional structure without excessive external complexity

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The housing is divided into distinct sub-assemblies (housing sub-assembly and telescoping sub-assembly) with the telescoping section further segmented into retaining sections, allowing independent positioning and retention at multiple discrete locations

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If a telescoping sub-assembly with multiple retaining positions is implemented, then the adaptability to varying depth positions is improved, but the sealing difficulty increases

Engineering Contradiction:
Improvemulti-position retention capabilityVSAvoidsealing structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Sealing elements are strategically placed at specific locations within the telescoping sub-assembly, with each sealing element tailored to its local position and function, ensuring effective sealing at each retaining position without requiring complex sealing throughout the entire structure

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Sealing elements act as intermediaries between the telescoping sub-assembly and the housing sub-assembly, creating effective seals at the interfaces and retaining positions while allowing the telescoping mechanism to move and lock at multiple positions

Inventive Principle:
Principle #24Intermediary (Mediator)
