Power-Saving Mode App Recovery via Scheduled Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices with information processing terminals, such as smartphones and tablets, face challenges in maintaining app functionality when transitioning to power-saving mode, particularly in Android systems where all applications are deactivated, leading to delayed responsiveness to user operations.
Innovation Solution
A device with a processor that executes a monitoring process to detect a set recovery time and initiates a recovery process to switch back to normal mode for installed apps, using a mediation unit to store and manage recovery time information, ensuring apps can recover from power-saving mode at predetermined times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the device transitions to power-saving mode to reduce power consumption, then power consumption is reduced, but app responsiveness deteriorates and user operations are delayed
Solution Approach 1:
The system performs preliminary actions by setting up a monitoring mechanism that proactively detects the arrival of predetermined times even while in power-saving mode. When the monitored time arrives, the system promptly transitions from power-saving mode to normal mode, ensuring apps can recover and respond without unnecessary delay. This preliminary monitoring setup resolves the contradiction by maintaining minimal active functionality during power-saving mode while ensuring rapid responsiveness when needed.
2Use of energy by moving object
If all applications are deactivated in power-saving mode to save energy, then power consumption is reduced, but app functionality is lost and user operations cannot be performed
Solution Approach 1:
The system establishes a preliminary monitoring mechanism that remains active during power-saving mode to detect predetermined times. This ensures that when the monitored time arrives, the system can immediately transition to normal mode and restore app functionality, maintaining reliability without requiring continuous full operation.
Solution Approach 2:
The system employs periodic action by monitoring for specific predetermined times rather than maintaining continuous full operation. Apps are deactivated during power-saving mode but can be promptly recovered at monitored intervals, achieving energy savings while preserving the ability to restore functionality when needed.
3Loss of time
If resident apps are kept executable in power-saving mode to maintain responsiveness, then app responsiveness is improved, but power consumption increases
Solution Approach 1:
The system uses periodic action by monitoring for specific predetermined times rather than maintaining continuous app execution. Apps remain deactivated during power-saving mode but are promptly recovered when their monitored times arrive, achieving responsiveness without the continuous power consumption of keeping apps permanently executable.
Solution Approach 2:
The monitoring mechanism performs preliminary detection of predetermined times during power-saving mode, enabling the system to transition to normal mode only when necessary. This preliminary monitoring allows the system to maintain low power consumption while ensuring apps can respond promptly when their specific times are reached.

AI summary
A device is provided that includes an operation unit having a program installed therein and including a processor that is configured to execute a first monitoring process of monitoring an arrival of a first time that is set up in advance, and a setting process of setting up the first time to be monitored in the first monitoring process in response to a request from the program. When the arrival of the first time is detected in the first monitoring process, the setting process causes the program to recover from a transitioned state to which the program transitions when the operation unit is in a power-saving mode.
