Solution Overview

Problem

Conventional computer systems require returning to the working mode to switch between different sleeping modes, leading to prolonged switching times and unnecessary power consumption due to the need to switch all power supplies on and off.

Innovation Solution

A computer with a power saving state control function that includes power supply assemblies, a storage module, and a power management module, allowing direct switching between sleeping modes by determining the necessary power supply assemblies to be switched on or off based on trigger events, without going through the working mode.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the computer system returns to working mode to switch between sleeping modes, then the switching between different sleeping modes can be achieved, but the switching time is prolonged and unnecessary power is consumed

Engineering Contradiction:

Improvesleeping mode switching capabilityVSAvoidswitching time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The power supply system is segmented into multiple independent power supply assemblies, each corresponding to different functional modules. This allows selective activation of power supplies based on the target sleeping mode, enabling direct transitions without requiring all power supplies to be activated as in the conventional working mode transition.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The control module pre-judges the target sleeping mode before transition and determines which power supply assemblies need to be activated. This preliminary action allows the system to prepare and switch power supplies in advance, avoiding the time-consuming process of returning to working mode first.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If the computer system returns to working mode to switch between sleeping modes, then the switching between different sleeping modes can be achieved, but unnecessary power is consumed due to switching all power supplies on and off

Engineering Contradiction:

Improvesleeping mode switching capabilityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

Different power supply assemblies are selectively activated based on the specific sleeping mode requirements. Instead of switching all power supplies on and off during mode transitions, only the necessary power supplies for the target mode are activated, reducing energy consumption during switching operations.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The control module pre-determines which power supply assemblies need to be activated for the target sleeping mode before the transition occurs. This allows the system to avoid unnecessary power supply switching and reduce energy consumption by activating only the required power supplies.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If all power supplies are switched on to return to working mode, then the computer can enter any sleeping mode, but the power consumption increases during the transition process

Engineering Contradiction:

Improvesleeping mode accessibilityVSAvoidpower consumption during transition

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The power supply system is divided into multiple independent assemblies that can be selectively activated. This segmentation allows the system to activate only the necessary power supplies for the target sleeping mode, avoiding the need to switch all power supplies on during transitions, thus reducing power consumption while maintaining accessibility to all sleeping modes.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The control module performs preliminary judgment to determine the target sleeping mode and identifies which power supply assemblies need to be activated. This preliminary action enables the system to activate only the necessary power supplies, reducing power consumption during transitions while ensuring the computer can still enter any required sleeping mode.

Inventive Principle:

Principle #10Preliminary action

AI summary

A computer has a plurality of sleeping modes to be switch directly. The power supply assemblies provide a plurality of power supplies to elements in the computer. The storage module is used to store executing data corresponding to each sleeping mode. The power management module is used to set the number of the power supply assemblies which need to be switched on in each sleeping mode. The control module determines the sleeping mode which is switched to according to a received trigger event and sends a first switching signal to the storage module to make the storage module store the executing data and a second switching signal to the power management module to make the power management module set the number of the power supply assemblies and switches the sleeping mode of the computer directly.
