Display Deactivation Power Management for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rapid advancement of electronic devices in processing capabilities leads to increased battery consumption due to the ability to perform multiple functions simultaneously, resulting in quick battery depletion, despite their limited battery capacity.
Innovation Solution
An electronic device equipped with a mode control module that senses inactive states and acquires information about objects maintaining active processor states, allowing it to output information and manage battery usage by controlling the operation of these objects, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple functions are activated simultaneously in the electronic device, then the processing capability and functionality are improved, but the battery consumption increases
Solution Approach 1:
The system dynamically adjusts the operational state of objects based on display activation status. When the display is deactivated, the processor automatically transitions eligible objects to an inactive state, creating a dynamic power management system that adapts to user interaction patterns rather than maintaining static operational states
Solution Approach 2:
The system changes the operational parameter (active/inactive state) of objects based on display state. By monitoring display activation and相应地 adjusting object operational parameters, the system achieves power savings without permanently disabling functionality, allowing quick resumption when display is reactivated
2Use of energy by moving object
If the display is deactivated to save power, then the battery consumption is reduced, but the user cannot see information about operating objects
Solution Approach 1:
The system introduces an intermediary information presentation mechanism that bridges the gap between display deactivation and information needs. By presenting object information through alternative modalities (haptic feedback, audio output, or simplified UI elements) when display is inactive, the system maintains information accessibility without requiring full display activation
Solution Approach 2:
The system provides self-service information notification by automatically detecting when objects are operating during display deactivation and proactively notifying users through available channels. This eliminates the need for users to manually check or infer system state, as the device independently manages information communication
3Reliability
If objects continue to operate in active state during display deactivation, then the processing capability is maintained, but the battery life is reduced
Solution Approach 1:
The system segments objects into different operational categories (eligible for inactive state vs. requiring active state) based on their functional characteristics. This segmentation allows selective power management where appropriate objects can be deactivated during display off periods while critical objects maintain active state, achieving granular power control

AI summary
An electronic device and method for entering an inactive mode, the electronic device including a display; and one or more processors. The processors may implement the method, which includes detecting an input to the electronic device indicating deactivation of a display of the electronic device or entrance into an inactive mode, detecting whether one or more objects executing one the one or more processors force the one or more processors to remain in an active mode, and when the one or more objects are detected, retrieving information on the one or more objects and display on the display the retrieved information.
