Solution Overview

Problem

Existing telecommunications networks face challenges in conditioning bi-directional RF signals over coaxial cables, as existing solutions require separate line conditioners for downstream and upstream signals at different locations, making it cumbersome to manage signal strength variations across bandwidths.

Innovation Solution

A signal conditioning device with dual plug-in sockets allows for independent conditioning of both downstream and upstream signals using a single device at a single location, employing diplexers to multiplex and condition RF signals within different frequency bands, enabling flexible installation and replacement of signal conditioner circuits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate line conditioners are used for downstream and upstream signals at different locations, then signal conditioning can be performed for each frequency band, but the device complexity and management difficulty increase

Engineering Contradiction:

Improvesignal conditioning capabilityVSAvoidnumber of conditioners

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines separate downstream and upstream signal conditioners into a single dual-socket signal conditioning device. The housing contains two independent plug-in sockets - one for downstream frequency band conditioning and one for upstream frequency band conditioning - allowing both signal paths to be conditioned at a single location rather than requiring separate conditioners at different locations.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The signal conditioning device performs multiple functions within a single unit. It conditions both downstream signals (carrying information from headend to user device) and upstream signals (carrying information from user device to headend) across different frequency bands, making the device universal for bi-directional RF signal management.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If separate line conditioners are installed at different locations, then each signal path can be conditioned independently, but the ease of operation and maintenance deteriorate

Engineering Contradiction:

Improvesignal path independenceVSAvoidmanagement convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent merges independent downstream and upstream conditioning capabilities into a single accessible housing. Both plug-in sockets are located on the exterior surface, allowing technicians to independently configure and maintain each frequency band's signal conditioning without navigating to separate locations or disrupting the other signal path.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If multiple separate conditioners are used, then comprehensive signal conditioning is achieved, but installation and maintenance time increase

Engineering Contradiction:

Improvesignal conditioning coverageVSAvoidinstallation and maintenance time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent consolidates what would require multiple separate installations into a single device installation. The housing contains both downstream and upstream plug-in sockets that can be configured simultaneously during one installation event, and both can be maintained during a single service visit, significantly reducing the time loss compared to managing separate conditioners at different locations.

Inventive Principle:

Principle #5Merging (Combining)
