Solution Overview

Problem

Current server power management systems are inadequate for ensuring complete data backup during power outages, as they often lack sufficient backup power to execute the backup process efficiently.

Innovation Solution

A server design that includes a control module, power-supply unit, storage unit, and switch unit, where the storage unit is charged when the server is powered on and can supply power when it is powered off, utilizing a battery management module to manage charging and discharging, and a switch unit to isolate and output power, ensuring continuous backup even during power loss.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the server uses conventional backup power systems, then the server can maintain basic backup functionality, but the backup power is insufficient to cover the execution of the backup process for enormous data storage

Engineering Contradiction:

Improvebackup power capacityVSAvoiddata backup completion

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The storage unit is charged in advance during normal operation (when the server is powered on) so that sufficient energy is stored before a power outage occurs. This preliminary charging action ensures that when the server is powered off, the storage unit can immediately supply the necessary power to complete the backup process without interruption.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The storage unit acts as an intermediary energy storage device between the power-supply unit and the control module. It receives power from the power-supply unit during normal operation and releases stored energy to the control module during power outages, enabling continuous backup operations without direct reliance on external power sources.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the server continuously monitors and manages power for large data backup, then backup reliability improves, but power consumption increases beyond what standard backup power can provide

Engineering Contradiction:

Improvedata backup reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

Instead of continuous power consumption, the system uses periodic charging during normal operation and periodic discharging during power outages. The storage unit is charged during intervals when the server is running and discharged only when needed, creating a cyclical pattern that reduces overall energy consumption while maintaining backup reliability.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The storage unit manages its own charging and discharging cycles autonomously based on the server's operational state. It automatically charges when power is available and discharges when power is needed, reducing the need for complex external power management systems and minimizing overall power consumption.

Inventive Principle:

Principle #25Self-service

3Reliability

If the server lacks a dedicated storage unit for power management, then device complexity is reduced, but the server cannot maintain data backup operations during power outages

Engineering Contradiction:

Improveuninterrupted backup operationVSAvoidpower management structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The storage unit serves multiple functions: it acts as an energy storage device, a power management component, and a backup power source. By integrating these functions into a single component, the system achieves reliable uninterrupted backup operations without proportionally increasing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A server includes a control module, a power-supply unit, a storage unit and a switch unit. The control module is electrically connected to a storage device. When the server is powered on, a first power is transmitted to from the power-supply unit to the storage unit and the switch unit, and received by the switch unit to generate a third power. When the server is powered off, the storage unit is triggered to transmit a second power to the switch to make the switch transmit the third power. The control module is provided to control a transmission information between the storage device and a buffer of the control module. When the server is powered on again, the control module continually works according to the transmission information stored in the buffer.
