Solution Overview

Problem

In high-density patching applications, it is challenging to identify and trace the ends of optical fiber patch cords due to their compact arrangement, requiring specialized equipment and complex connections, which complicates the process of determining which connector corresponds to another across a distance.

Innovation Solution

An optically traceable patch cord with a trace assembly and optical tracing fiber that emits light from one end and is detectable at the other, allowing for visual or sensor-based identification of the corresponding connector, even in densely packed environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If copper trace assembly is used in optical fiber patch cord, then electrical signal transmission is enabled, but specialized testing equipment with electric power and light source is required

Engineering Contradiction:
Improvetracing capabilityVSAvoidtesting equipment
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces the electrical tracing mechanism with an optical tracing mechanism. Instead of using copper wires and electrical signals that require power sources and specialized testing equipment, the invention uses an optical fiber trace assembly that transmits light signals through the patch cord. This substitution eliminates the need for complex electrical testing equipment while maintaining the tracing functionality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention extracts and removes the copper trace assembly from the optical fiber patch cord construction. By eliminating the copper wiring and associated electrical tracing components, the patent simplifies the overall system and removes the dependency on specialized electrical testing equipment, keeping only the essential optical fiber trace assembly.

Inventive Principle:
Principle #2Taking out (Extraction)

2Area of stationary object

If connectors are plugged in high density application, then space utilization is improved, but optical tracing becomes difficult due to limited access

Engineering Contradiction:
Improvespace utilizationVSAvoidtracing operation
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent introduces an intermediary mechanism - the optical fiber trace assembly that runs alongside the main optical fibers within the patch cord itself. This intermediary trace path allows light to be transmitted through the cord body without requiring access to the connectors, enabling tracing operations even when connectors are densely plugged in and inaccessible.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention shifts the tracing operation from the connector end interface to the cable body dimension. Instead of attempting to connect tracing equipment to crowded connector interfaces, the optical trace assembly provides an alternative path through the cable interior, moving the tracing function to a different spatial dimension where access is not constrained by connector density.

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

3Area of stationary object

If patch cords are arranged in high density, then area efficiency is improved, but identification of corresponding connectors becomes difficult

Engineering Contradiction:
Improvepatching areaVSAvoidconnector correspondence
Core Design Contradiction:
Area of stationary objectVSLoss of information

Solution Approach 1:

The patent utilizes light transmission through the optical fiber trace assembly to provide visual indication of connector correspondence. By transmitting light through the trace assembly and observing the light output at the other end, users can visually trace and identify which connectors are paired, effectively using optical signal presence/absence as an identification mechanism in high-density environments.

Inventive Principle:
Principle #32Color changes
