Solution Overview

Problem

Existing power infrastructure for server systems is often mounted within racks, occupying valuable space and making it difficult to scale power distribution in response to changes in server configurations, leading to extended downtime during reconfiguration.

Innovation Solution

A modular and scalable power infrastructure system that mounts outside the rack, using a chassis with a power cable interface box to receive AC power, power supply units to output DC power to a busbar, and a battery backup unit to charge and discharge, allowing for flexible and efficient power management without occupying server space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If power infrastructure is mounted within racks, then power can be provided to servers, but valuable rack space is occupied and computing capacity is reduced

Engineering Contradiction:
Improvepower provision to serversVSAvoidrack space occupied
Core Design Contradiction:
PowerVSArea of stationary object

Solution Approach 1:

The power infrastructure is extracted from the rack interior and relocated to an external mounting position. The power distribution unit includes a chassis configured to mount on the exterior of the rack, with power supply units and battery backup units disposed within the chassis outside the rack space, thereby providing power to servers without occupying valuable computing space within the rack.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If power systems are tailored to server configurations, then power can be optimized for specific server types, but changing server configurations requires total reworking of the power system causing extended downtime

Engineering Contradiction:
Improvepower optimization for server typesVSAvoiddowntime during reconfiguration
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The power distribution unit is divided into modular components including multiple power supply units that can be independently installed, removed, or replaced in slots within the chassis. Each power supply unit can be configured for specific server power requirements, and individual units can be swapped without affecting other components or requiring system shutdown, enabling rapid adaptation to changing server configurations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The power infrastructure is designed to be dynamically reconfigurable through the modular power supply units that can be easily added or removed from slots. This dynamic design allows the power system to adapt to varying server configurations and power demands without requiring complete reworking of the entire power system, minimizing downtime during changes.

Inventive Principle:
Principle #15Dynamics
