Solution Overview

Problem

Manually shutting down or restarting multiple servers in a large machine room is inefficient and inconvenient, as existing remote power control solutions require additional installations and increased costs, making them unsuitable for large setups.

Innovation Solution

A power management circuit integrated with a server that allows remote control of power-off and restart operations through a network, using a motherboard circuit with a network module and board control unit to receive and execute power-off commands, and a switching unit to manage power supply, enabling independent operation and initialization procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a smart multi-receptacle power outlet is used to provide remote switching operations, then remote power control capability is improved, but installation cost and device complexity increase due to additional components and configuration requirements

Engineering Contradiction:

Improveremote power control capabilityVSAvoidinstallation complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the remote power control function with the existing power supply module and motherboard circuit by integrating a power management circuit. This combines multiple functions (power supply, remote control, switching) into a single unified system, eliminating the need for separate smart power outlets and reducing installation complexity while maintaining remote power control capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The power management circuit serves multiple functions: it manages power supply to the motherboard circuit, enables remote power control through network communication, and provides switching operations. This multi-functional design replaces the need for dedicated smart power outlets, reducing device complexity while maintaining ease of operation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If additional smart power outlet is installed in the machine room, then remote switching operation is enabled, but installation cost increases

Engineering Contradiction:

Improveremote switching operationVSAvoidinstallation cost

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The patent combines the remote switching operation functionality into the existing power supply module by integrating a power management circuit. This merging eliminates the need to install additional smart power outlets in the machine room, thereby reducing installation costs while maintaining the ability to perform remote switching operations.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The power management circuit enables the power supply module to perform remote control operations autonomously without requiring external smart power outlets. The system uses its own integrated resources (power supply module, motherboard circuit, network module) to achieve remote switching, eliminating the need for additional expensive components.

Inventive Principle:

Principle #25Self-service

3Productivity

If manual shutdown is performed in the machine room, then power-off operation is achieved, but efficiency decreases due to time-consuming manual intervention

Engineering Contradiction:

Improvepower-off operation efficiencyVSAvoidmanual intervention time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical manual shutdown process with an automated electronic system. The power management circuit receives power-off commands through the network module and automatically controls the power supply module to disconnect power to the motherboard circuit, eliminating the need for manual physical intervention and significantly improving power-off operation efficiency.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The power management circuit enables the system to perform power-off operations autonomously based on remote commands. The integrated circuit automatically manages the power supply disconnection without requiring manual intervention, thereby reducing time loss and improving productivity in power-off operations.

Inventive Principle:

Principle #25Self-service

AI summary

A server is provided in the present disclosure, and the server includes a power module, a motherboard circuit, and a power management circuit. The power management circuit is coupled to the motherboard circuit and the power module. The motherboard circuit receives a remote control signal through a network module and outputs a power-off command to the power management circuit according to the remote control signal. The power management circuit causes the power module to stop supplying power to the motherboard circuit for a predetermined time according to the power-off command. After the predetermined time, the power management circuit causes the power module to supply power again to the motherboard circuit to execute an initialization procedure.
