Solution Overview

Problem

Existing wake-up mechanisms in electronic devices often lead to power consumption issues and false touch wake-up problems, especially when devices are in low-power modes.

Innovation Solution

A wake-up mechanism controlling method that initializes a driver program for a login device, allowing it to support or not support wake-up mechanisms based on the device's state, thereby optimizing power usage and preventing false wake-ups.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the login device is placed in low-power mode to save energy, then power consumption is reduced, but false touch wake-up problems occur

Engineering Contradiction:

Improvepower consumptionVSAvoidfalse wake-up rate

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent applies dynamics by making the wake-up mechanism configurable based on device state. The system dynamically adjusts whether the login device supports wake-up functionality according to the current state (first state vs. second state), allowing optimal balance between power saving and reliability in different operational contexts

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of wake-up mechanism availability based on device state. By controlling whether the login device supports wake-up in different states, the system optimizes the trade-off between power consumption and false wake-up prevention, achieving both energy efficiency and operational reliability

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If the login device supports wake-up mechanism in low-power mode, then user convenience is improved, but power consumption increases

Engineering Contradiction:

Improvewake-up convenienceVSAvoidpower consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system dynamically controls wake-up support based on device state, enabling convenient wake-up functionality only when appropriate (first state) while disabling it when power saving is prioritized (second state), thus balancing user convenience with power consumption

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the wake-up support parameter conditionally based on device state, allowing the system to optimize between ease of operation and power consumption by enabling or disabling wake-up functionality in different operational contexts

Inventive Principle:

Principle #35Parameter changes

AI summary

A wake-up mechanism controlling method includes following operations: performing, by a processor of an electronic device, an initialization process for a driver program of a login device; controlling, by the processor, the login device to be in a low-power mode and to support a wake-up mechanism when the electronic device is in a first state, in which the login device is configured to log into an operating system of the electronic device when the login device is waken up; and controlling, by the processor, the login device to be in the low-power mode and not to support the wake-up mechanism when the electronic device is in a second state.
