Solution Overview

Problem

Conventional smartphones set different time periods for screen timeout on lock screens and other screens, causing user discomfort due to inconsistent timing.

Innovation Solution

A mobile terminal, display control method, and non-transitory computer-readable medium that set the same predetermined time period for screen timeout on both lock screens and other screens, allowing users to choose the duration before timeout and improving user convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different time periods are set for screen timeout on lock screens and other screens, then each screen can be optimized for its specific use case, but user discomfort occurs due to inconsistent timing

Engineering Contradiction:

Improvescreen timeout optimizationVSAvoiduser convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies homogeneity by setting the same screen timeout duration for both lock screens and other screens. This eliminates the inconsistency between different screen types, ensuring uniform user experience across all screens while maintaining the ability to optimize timeout settings for different usage scenarios.

Inventive Principle:

Principle #33Homogeneity

2Device complexity

If the screen timeout duration is fixed, then the system operation is simple, but users cannot adjust according to their preferences

Engineering Contradiction:

Improvetimeout controlVSAvoiduser preference adjustment

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamics by allowing the screen timeout duration to be dynamically adjustable by users. The system provides multiple timeout duration options that users can select based on their preferences, transforming the fixed timeout into a flexible, user-adaptable parameter while maintaining simple system operation.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If the screen timeout duration is adjustable, then users can set it as desired, but the system complexity increases

Engineering Contradiction:

Improveuser convenienceVSAvoidtimeout control

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by allowing users to adjust the screen timeout duration parameter within a predefined set of options. This approach provides user convenience through customizable timeout settings while controlling system complexity by limiting adjustments to discrete, pre-determined parameter values rather than continuous adjustment.

Inventive Principle:

Principle #35Parameter changes

AI summary

The mobile terminal includes a display configured to display a lock screen and a controller configured to perform screen timeout when a non-operation state continues in the lock screen and also when the non-operation state continues in a screen other than the lock screen, wherein the controller sets the same predetermined time periods to a duration of the no-operation state in the lock screen before the screen timeout is performed and a duration of the non-operation state in the screen other than the lock screen before the screen timeout is performed.
