Background Reminder Apparatus Battery Protection via Local Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data processing devices, such as smartphones and tablets, face battery consumption issues when attempting to implement background reminding functions due to operation system restrictions, leading to potential battery depletion before the reminding event can occur.
Innovation Solution
A reminding apparatus with modules to determine reminding time, enter a background running state, check battery levels, and write local notifications to the operation system when battery levels are low, allowing the system to automatically trigger reminders and conserve battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the APP runs in the background to implement reminding functions, then the reminding function can be implemented, but the battery level will be depleted
Solution Approach 1:
The patent extracts the battery level checking function from the background running APP and implements it through the operation system's battery monitoring mechanism. The operation system automatically monitors battery levels and can suspend background APPs when low battery conditions are detected, separating the reminding function from continuous battery consumption.
Solution Approach 2:
The patent implements a feedback mechanism where the operation system continuously monitors battery level and provides feedback to control background APP execution. When battery level falls below a threshold, the operation system suspends the background APP, creating a closed-loop control system that adapts to battery conditions.
2Reliability
If the APP continuously plays audio to maintain background running state, then the APP can run in the background, but battery consumption increases
Solution Approach 1:
Instead of continuous audio playback, the patent uses periodic battery level checking and operation system-based reminder triggering. The APP checks battery levels periodically and relies on the operation system to manage background execution, replacing continuous action with periodic monitoring and system-coordinated execution.
Solution Approach 2:
The operation system acts as an intermediary between the background APP and the user interface. It manages the APP's execution state, handles battery level monitoring, and coordinates reminder triggering, allowing the APP to run in the background without continuous user-facing operations that would consume battery.
3Adaptability or versatility
If the operation system allows background running of all APP types, then background functionality is expanded, but battery management becomes difficult
Solution Approach 1:
The patent makes the operation system's battery monitoring and suspension mechanism universal, applying it across all APP types that wish to run in the background. This unified approach simplifies battery management by using a single set of rules and mechanisms that work for all background APPs, rather than requiring separate management for each APP type.

AI summary
A reminding apparatus includes: a reminding module, configured to determine reminding time of the reminding apparatus and a reminding event corresponding to the reminding time, and trigger the reminding event when the reminding time is up; a background miming module, configured to indicate an operation system of the data processing device to trigger the reminding apparatus to enter a background running state after detecting a switch instruction; a battery level checking module, configured to check battery level of the data processing device when the reminding apparatus runs in the background; and a battery level protecting module, configured to write a local notification into the operation system when the battery level is lower than a predefined threshold, set triggering time of the local notification as the reminding time, and trigger the reminding apparatus to enter a pending state. The local notification can be triggered automatically by the operation system.
