Solution Overview

Problem

The management and installation of fiber optic cables require improved solutions for ease of handling and accessibility, as existing technologies do not adequately address these concerns in telecommunications networks.

Innovation Solution

An adapter block assembly with a retention arrangement and a fixture for assembling the adapter block, which includes housing pieces with securement and alignment features to facilitate the alignment and securement of multi-fiber connectors, allowing for efficient assembly and labeling of the adapter block without removing it from the fixture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fiber optic networks are extended to meet increasing demand, then network coverage and capacity are improved, but cable management complexity and installation difficulty increase

Engineering Contradiction:
Improvenetwork coverageVSAvoidcable management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adapter block assembly is divided into multiple housing pieces (first housing piece, second housing piece, etc.) that can be separately assembled and then joined together using retention arrangements. This segmentation allows for easier manufacturing, assembly, and cable management while maintaining the ability to support extended network coverage through modular expansion.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If multiple adapters are installed in the adapter block assembly, then fiber optic connection capacity is improved, but alignment precision and securement difficulty increase

Engineering Contradiction:
Improvenumber of adaptersVSAvoidalignment precision
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

Multiple adapters are combined within a single adapter block assembly that provides unified alignment features and securement mechanisms. The housing pieces cooperate to define a common interior space with integrated alignment structures, ensuring precise positioning of multiple adapters simultaneously while simplifying the securement process through centralized retention arrangements.

Inventive Principle:
Principle #5Merging (Combining)

3Stability of the object's composition

If a retention arrangement is implemented to hold housing pieces together, then structural stability is improved, but assembly complexity increases

Engineering Contradiction:
Improvestructural stabilityVSAvoidassembly complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The retention arrangement is designed to automatically engage and secure the housing pieces together through self-aligning features. The first and second housing pieces include complementary retention structures that automatically mate when the pieces are brought together, providing structural stability without requiring additional fastening operations or complex assembly procedures.

Inventive Principle:
Principle #25Self-service

4Ease of manufacture

If the adapter block assembly is designed with multiple housing pieces, then ease of manufacture and assembly are improved, but the number of components and potential failure points increases

Engineering Contradiction:
Improveease of assemblyVSAvoidreliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The housing pieces are pre-configured with integrated retention arrangements and alignment features during manufacturing. These preliminary actions ensure that when the housing pieces are assembled, they automatically achieve proper alignment and securement, reducing assembly complexity while maintaining reliability through pre-engineered connection points that minimize potential failure locations.

Inventive Principle:
Principle #10Preliminary action

AI summary

An adapter block assembly includes two housing pieces that cooperate to hold one or more adapters therebetween. The two housing pieces are removably latched together. Labels can be placed over the latches. Certain types of adapter block assemblies are configured to receive multi-fiber plug connectors. Certain types of adapter block assemblies include securement arrangements at opposite ends thereof to aid in mounting the adapter block assemblies to frames, trays, chassis, or other such structures.
