Solution Overview

Problem

Installing fiber optic systems in multi-unit buildings is challenging due to space limitations and complex architecture, particularly in older buildings being retro-fitted, as existing systems require significant space for fiber optic devices and complex setups.

Innovation Solution

A fiber optic system with a collector and terminal assembly (CTA) that includes a multi-fiber optic cable with branches and single-fiber optic jumpers, along with adapters for secure connections, allowing for a smaller footprint and simplified installation by distributing fiber optic signals directly to multiple units from a central location, reducing the need for multiple fiber distribution hubs and terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional fiber optic distribution systems with multiple fiber distribution hubs and terminals are installed, then complete fiber optic coverage can be achieved, but the space required within the building increases significantly

Engineering Contradiction:
Improvefiber optic coverageVSAvoidspace required
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent combines the fiber distribution hub and fiber distribution terminal into a single integrated Collector and Terminal Assembly (CTA). This merging eliminates the need for separate distribution hubs and terminals, reducing the total space required while maintaining complete fiber optic coverage across multiple building units.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The CTA serves multiple functions simultaneously: it acts as both a collection point for feeder cables and a distribution point for branch cables to multiple units. This multi-functionality replaces the need for separate specialized devices, achieving comprehensive coverage with minimal space occupation.

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

2Reliability

If traditional fiber optic distribution systems are installed, then all units can be connected, but the installation complexity increases due to multiple devices and cables

Engineering Contradiction:
Improveconnection completenessVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

By integrating the distribution hub and terminal functions into one CTA device, the system reduces the number of separate components that need to be installed, configured, and maintained. This merging simplifies the overall system architecture while ensuring all units remain connected through the unified structure.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If multiple fiber distribution hubs and terminals are used, then comprehensive signal distribution is achieved, but the footprint within the building increases

Engineering Contradiction:
Improvesignal distribution capabilityVSAvoidbuilding footprint
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The CTA utilizes vertical space within the building by allowing installation on multiple floors, transitioning from a horizontal footprint approach to a vertical deployment strategy. This enables comprehensive signal distribution across multiple units while minimizing the horizontal building footprint occupied.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The integration of collection and terminal functions into a single compact CTA device reduces the overall space requirement while maintaining the ability to distribute signals to multiple units, achieving versatility without proportionally increasing footprint.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If traditional fiber optic systems are installed in older buildings, then fiber optic service can be provided, but installation difficulty increases due to space constraints

Engineering Contradiction:
Improveretrofit capabilityVSAvoidinstallation ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The fiber optic system is segmented into modular CTAs that can be independently installed on different floors of older buildings. This segmentation allows retrofit installation without requiring complete building-wide installation planning, making the process more manageable and easier to execute in constrained spaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

By enabling vertical installation across multiple floors, the CTA system adapts to older buildings with limited horizontal space. Installers can place CTAs on available floors, utilizing the building's vertical dimension to overcome space constraints typical of retrofits in older structures.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A fiber optic collector and terminal assembly (CTA) can include a multi-fiber optic cable having a tail portion and first and second multi-fiber branches optically coupled to the tail portion. The first and second multi-fiber optic branches each have fewer fibers than the tail portion. The CTA also includes a plurality of single-fiber optic jumpers optically coupled to the first multi-fiber optic branch. Additionally, the CTA includes an adapter for securing a connection between a fiber of one of the plurality of single-fiber optic jumpers and a fiber of a single-fiber optic drop.
