Solution Overview

Problem

Existing methods for adjusting screen-on duration on terminals are tedious and inefficient, requiring users to manually navigate settings to extend the display time, which negatively impacts user experience, especially in scenarios where prolonged screen-on time is needed.

Innovation Solution

A method and terminal implementation that detects user interactions to automatically adjust screen-on duration through a user interface, allowing users to extend display time without entering settings, and optionally adjusts duration based on interaction frequency or task type.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the terminal automatically dims or disables the display after a short screen-on duration, then power consumption is reduced, but the user experience deteriorates when prolonged display time is needed for tasks like reading

Engineering Contradiction:
Improvepower consumptionVSAvoiduser experience
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The patent implements dynamic screen-on duration adjustment by detecting user interaction frequency and automatically extending the screen-on time when users repeatedly trigger the display. The system transitions from a static, fixed screen-on duration to a dynamic, adaptive duration that responds to user behavior patterns, thereby maintaining power efficiency while accommodating extended usage scenarios like reading without requiring manual settings changes.

Inventive Principle:
Principle #15Dynamics

2Duration of action of moving object

If the user manually adjusts screen-on duration through settings, then the display can maintain screen-on state longer, but the adjustment process becomes tedious and time-consuming

Engineering Contradiction:
Improvescreen-on durationVSAvoidadjustment time
Core Design Contradiction:
Duration of action of moving objectVSLoss of time

Solution Approach 1:

The patent implements self-service by enabling the terminal to automatically adjust its own screen-on duration based on detected user interactions. Instead of requiring users to manually navigate settings and change parameters, the system monitors user behavior (such as repeated touch operations) and autonomously extends the screen-on duration to match actual usage needs, thereby eliminating the time-consuming manual adjustment process while maintaining appropriate power management.

Inventive Principle:
Principle #25Self-service

3Use of energy by stationary object

If the terminal provides fixed screen-on duration options, then power consumption is controlled, but flexibility is reduced when users need different durations for different tasks

Engineering Contradiction:
Improvepower consumption controlVSAvoidscreen-on duration flexibility
Core Design Contradiction:
Use of energy by stationary objectVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by dynamically modifying the screen-on duration parameter based on detected user interaction patterns. The system monitors the frequency of user operations (such as touch operations) and adjusts the screen-on duration parameter in real-time, transitioning from fixed, pre-defined duration options to a flexible, continuously adjustable parameter that adapts to different task requirements while maintaining power consumption control through automated adjustment rather than user selection.

Inventive Principle:
Principle #35Parameter changes

AI summary

A method for adjusting screen-on duration of a terminal and the terminal are provided. In the method, the terminal detects whether a user operation meets a pre-stored condition for adjusting the screen-on duration, and when the condition is met, the terminal adjusts the screen-on duration of the terminal, or displays, on a display, a UI used for adjusting the screen-on duration of the terminal, where the UI is configured to: provide an adjustment manner of adjusting the screen-on duration of the terminal, and receive adjustment information used to adjust the screen-on duration that is entered by a user according to the adjustment manner. According to embodiments of the present invention, a process of adjusting the screen-on duration of the terminal by the user is simplified, and efficiency of modifying the screen-on duration is improved.
