Solution Overview

Problem

The existing methods for enabling a mobile phone screen are inconvenient, especially for large screens, as they require physically locating and pressing a button, which is cumbersome for one-hand operation and inefficient with frequent use.

Innovation Solution

A method and apparatus that utilize pressure operations on a touchscreen to enable the screen, where a first pressure value greater than or equal to a threshold activates screen display data in a portion of the screen, with subsequent pressure duration and changes determining the display attributes and data, allowing partial screen illumination without fully lighting the display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a physical button is used to enable the screen, then the screen can be activated, but it is inconvenient for one-hand operation and requires frequent finding and pressing of the button

Engineering Contradiction:
Improveconvenience of screen activationVSAvoidtime for finding and pressing button
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the mechanical physical button system with a touch-based pressure detection system on the touchscreen. The touchscreen detects pressure operations directly on the display surface, eliminating the need for separate mechanical buttons and enabling more intuitive and convenient operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a pressure detection mechanism as an intermediary between the user's finger and the touchscreen. This intermediary detects pressure operations and triggers screen activation without requiring the user to locate or press a physical button, thereby reducing operation time and improving convenience.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If the entire screen is illuminated to display information, then all information is visible, but power consumption increases

Engineering Contradiction:
Improvecompleteness of information displayVSAvoidpower consumption of display
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The patent divides the screen into multiple display regions, allowing selective illumination of only the necessary portions. When a pressure operation occurs, only the region containing the relevant information (such as notification area or specific content) is illuminated, while other regions remain dark, thereby reducing overall power consumption.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different display states to different regions of the screen. The pressed region and its associated information area are illuminated with appropriate brightness, while other regions remain in a dark or low-power state. This local quality approach ensures information visibility where needed while minimizing energy consumption elsewhere.

Inventive Principle:
Principle #3Local quality

3Productivity

If the screen is activated frequently to view information, then information access is enabled, but battery life is reduced

Engineering Contradiction:
Improvefrequency of information viewingVSAvoidbattery consumption
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent implements partial screen activation where only the necessary portion of the screen is illuminated based on the pressure operation location and type. This partial action approach allows frequent information viewing by activating only the minimal required screen area, thereby reducing battery consumption compared to full screen activation.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent employs periodic or intermittent screen activation based on user interaction patterns. The screen remains in a low-power state and is activated only when pressure operations are detected, allowing information to be displayed on demand rather than continuously, thus enabling frequent access while conserving battery life.

Inventive Principle:
Principle #19Periodic action

AI summary

Embodiments of the present invention provide a screen enabling method and apparatus, and an electronic device. The method includes: when a display screen of an electronic device is in a disabled state, detecting a first pressure value of a pressure operation performed on a touchscreen of the electronic device, where the display screen includes a first portion and a second portion; and displaying, in the first portion of the display screen, first screen display data according to a first display attribute when the first pressure value is greater than or equal to a preset pressure operation threshold, where the second portion keeps in a disabled state or is displayed in black, and the first display attribute includes at least a display luminance. The display screen is partially lighted by pressing the touchscreen, so that a user can view information of interest without fully lighting the display screen, and operate conveniently, thereby reducing power consumption caused by display in full screen.
