Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing screen control methods in electronic devices simply turn off the screen when no user input is detected, leading to unnecessary power consumption and lack of user engagement, without providing varied visual effects or intuitive control states.

Innovation Solution

A method and apparatus that gradually control the screen by changing chroma and adjusting lighting brightness when no operation event is generated, providing various visual effects and restoring the screen to an on state upon user input, using a screen control module to manage these processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the screen is simply turned off when no user input is detected, then power consumption is reduced, but user engagement and visual feedback are lost

Engineering Contradiction:

Improvepower consumptionVSAvoiduser engagement

Core Design Contradiction:

Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The screen control process is segmented into multiple stages: first period with chroma change, second period with brightness adjustment, and final period with screen off. This segmentation allows the system to provide gradual visual feedback while managing power consumption effectively at each stage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The screen control transitions from static on/off states to dynamic multi-stage control with changing chroma and brightness levels. This dynamic approach maintains user engagement through visual effects while progressively reducing power consumption.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the screen control provides varied visual effects, then user engagement is improved, but device complexity increases

Engineering Contradiction:

Improveuser engagementVSAvoidcontrol process complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent changes display parameters (chroma and brightness) through software control rather than adding complex hardware. This approach provides varied visual effects and user engagement while avoiding increased device complexity.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If the screen control is performed in multiple stages, then user engagement is improved, but time for screen response increases

Engineering Contradiction:

Improveuser engagementVSAvoidscreen response time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The screen control uses periodic action with defined time periods for each control stage. The first period handles chroma change, the second period handles brightness adjustment, and subsequent periods handle final screen off, providing structured time management that balances user engagement with response efficiency.

Inventive Principle:

Principle #19Periodic action

AI summary

An electronic device is provided. The electronic device is configured to check whether an event is generated during a first period in a state in which a screen is displayed, change a chroma of the screen when the event is not generated during the first period, check whether the event is generated during a second period, and adjust a lighting brightness of the screen when the event is not generated during the second period.
