Solution Overview

Problem

Digital subscriber line access multiplexers (DSLAMs) typically require external power supplies, leading to increased enclosures, site preparation complexity, and potential power outages disrupting service.

Innovation Solution

Integrating an AC power supply within the DSLAM enclosure, including an uninterruptible power supply (UPS) to provide onboard power, reducing the need for external enclosures and enhancing power reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If external power supplies are used for DSLAMs, then power can be provided to multiple enclosures, but the number of enclosures increases and site preparation complexity increases

Engineering Contradiction:

Improvepower supply coverageVSAvoidenclosure quantity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the power supply and DSLAM into a single integrated enclosure. The power supply is mounted within the DSLAM enclosure, eliminating the need for separate external power supply enclosures. This merging reduces the total number of enclosures from two (separate power supply and DSLAM enclosures) to one (integrated enclosure), directly resolving the technical contradiction between power supply coverage and enclosure quantity.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If external power supplies are used for DSLAMs, then power can be provided to multiple enclosures, but site preparation complexity increases

Engineering Contradiction:

Improvepower supply coverageVSAvoidsite preparation

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By integrating the power supply within the DSLAM enclosure, the patent eliminates the need for complex site preparation required for installing separate external power supply enclosures. The integrated design requires only a single enclosure installation location, simplifying civil work, mounting requirements, and overall deployment complexity compared to installing multiple separate enclosures.

Inventive Principle:

Principle #5Merging (Combining)

3Power

If external power supplies are used, then power can be provided to DSLAMs, but power outages can disrupt service

Engineering Contradiction:

Improvepower deliveryVSAvoidservice continuity

Core Design Contradiction:

PowerVSReliability

Solution Approach 1:

The patent incorporates an uninterruptible power supply (UPS) system within the integrated enclosure. The UPS includes energy storage components (such as batteries) that provide backup power capability. When main power fails, the UPS automatically takes over, cushioning against power outages and maintaining continuous service to DSLAMs, thus resolving the contradiction between power delivery and service continuity.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Power

If separate external power supply enclosures are used, then power can be provided to DSLAMs, but the number of components increases

Engineering Contradiction:

Improvepower provisionVSAvoidcomponent quantity

Core Design Contradiction:

PowerVSDevice complexity

Solution Approach 1:

The patent merges the power supply component with the DSLAM into a single integrated unit. Instead of having separate power supply enclosures and DSLAM enclosures as distinct components, the power supply is mounted within the DSLAM enclosure, reducing the total component count from two separate enclosures to one integrated enclosure, while maintaining full power provision capability.

Inventive Principle:

Principle #5Merging (Combining)
