Solution Overview

Problem

Existing telecommunications networks lack a reliable method to quickly and automatically identify the correct connection of subscriber lines to customer locations, complicating fault diagnosis and maintenance.

Innovation Solution

A plug-in module for telecommunications connection units equipped with a readable memory and a locking mechanism, allowing unique identification and ensuring secure, one-time installation, which can be read locally or remotely using a reading device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a plug-in module with readable memory is installed in the TAE, then identification speed and automation are improved, but device complexity increases

Engineering Contradiction:
Improveautomatic identificationVSAvoiddevice complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent uses a memory device that stores identification information as a digital copy of the TAE's identifying data. This allows the TAE to be identified by reading the stored information rather than through complex physical inspection or manual verification processes, thereby automating identification while keeping the added complexity minimal.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces manual identification methods (mechanical inspection, visual verification) with an automated reading device that electronically reads identification information from the memory. This substitution of mechanical/manual processes with electronic reading automation the identification process while avoiding significant mechanical complexity.

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

2Reliability

If a locking device is implemented to prevent removal, then connection reliability is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveconnection reliabilityVSAvoidease of operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking device is implemented as a separate functional component within the plug-in module, distinct from the memory device. This segmentation allows the locking mechanism to be independently optimized for reliability while the overall module design maintains ease of installation. The locking function is divided into specific mechanical elements that work together to provide secure attachment.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If remote reading capability is added, then measurement precision and fault diagnosis are improved, but device complexity increases

Engineering Contradiction:
Improveidentification accuracyVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The reading device is designed with universal functionality that allows it to read identification information from memory devices in multiple contexts - both remotely for automated identification and locally for detailed verification. This multi-functionality enables the same device to serve multiple purposes (remote reading, local reading, fault diagnosis, installation verification) without requiring separate specialized equipment for each function, thereby improving measurement precision while limiting the increase in overall device complexity.

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