Timer Management System Consolidating Resume Processes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent system resume required by multiple applications in electronic devices leads to increased battery consumption, and users face inconvenience when the device automatically powers off due to low battery, requiring a cold boot upon charging without notification.
Innovation Solution
An electronic device with a timer management system that consolidates application requests to minimize resume processes and automatically performs a cold boot when charging, using a receiving unit for time information, a time interval retaining unit, and a defining unit to set optimal timer activation times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system resumes frequently to execute predetermined processes for multiple applications, then the applications can execute their processes at regular time intervals, but the battery consumption increases
Solution Approach 1:
The patent merges multiple timer requests from different applications into a single consolidated timer mechanism. The timer management unit aggregates timing requests and coordinates system resume operations, reducing the total number of wake-up events while ensuring all applications receive their required process executions at appropriate intervals, thus lowering battery consumption without sacrificing application functionality
Solution Approach 2:
The patent implements dynamic timer management where the system adapts timer settings based on application requirements and system state. The timer management unit dynamically adjusts timing parameters and coordinates resume operations based on real-time conditions, optimizing the balance between application execution needs and power consumption by making intelligent decisions about when and how to wake the system
2Reliability
If the power is automatically switched off when the remaining battery level decreases below a predetermined value, then the battery is protected from over discharge, but the user has to manually cold boot the system when charging
Solution Approach 1:
The patent implements self-service functionality where the electronic device automatically performs cold boot operation when charging is detected after power-off due to low battery. The system monitors charging status and autonomously initiates system startup without requiring user intervention, making the device serve itself in the boot process while maintaining battery protection protocols
Solution Approach 2:
The patent uses feedback mechanisms where the system monitors battery level, power-off status, and charging detection to make intelligent decisions about automatic booting. The timer management unit and power management system exchange information about system state and charging conditions, using this feedback to determine when automatic cold boot should be executed, creating a closed-loop control system that balances battery protection with user convenience
Data Source
AI summary
In an electronic device provided with a resume function, a timer outputs a predetermined signal if a measured time value becomes a set time. Upon receiving the predetermined signal from the timer, a state control unit executes a resume process. A time information receiving unit receives time information that specifies a time interval, at which an application executes a predetermined process. A time interval retaining unit retains a time interval T for restoring the application to an executable state. A defining unit registers a set time with the timer on the basis of the received time information and the time interval T.
