Shutdown Notification Filtering for Low Power Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users miss important notifications, such as meeting reminders and unread text messages, due to unexpected device shutdowns caused by low power conditions or other factors, leading to user dissatisfaction.
Innovation Solution
A notification system that allows users to designate specific notifications to be displayed during a shutdown sequence, based on importance, notification type, and user contacts, ensuring that critical alerts are accessible before the device fully shuts down.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the device shuts down automatically due to low power conditions, then power consumption is reduced and battery life is extended, but users cannot access important notifications such as meeting reminders and unread text messages
Solution Approach 1:
The system performs preliminary action by displaying selected notifications on the lock screen before the device shuts down due to low power conditions. This allows users to access important notifications (such as meeting reminders and text messages) during the brief period when the device is still powered on, preventing information loss while maintaining the automatic shutdown function for power conservation.
2Loss of information
If all notifications are displayed on the lock screen during shutdown, then users can access important information, but the device complexity and power consumption increase
Solution Approach 1:
The system applies local quality by selectively displaying only certain types of notifications on the lock screen during shutdown, rather than showing all notifications. The notification system evaluates each notification's importance and filters them based on criteria such as user priority settings, notification type, and source application. This selective approach provides necessary information access while avoiding the complexity and power consumption of displaying every possible notification.
Solution Approach 2:
The system changes parameters by adjusting notification display based on dynamic conditions including battery power levels, user preferences, notification priority levels, and current device state. The notification system modifies which notifications are displayed and how they are presented according to these varying parameters, optimizing the balance between information access and system resource consumption.

AI summary
Shutdown notification techniques are described in which notifications associated with various applications and functionality of a device are presented in conjunction with a shutdown sequence. In one or more implementations, a shutdown of the device may be initiated automatically in response to low power conditions, device/application errors, restarts, or explicitly by a user. A notification system of a device may be configured to enable designation of particular notifications to show upon shutdown. Notifications to output at shutdown may be selected based upon various criteria including but not limited to selection based on a perceived importance, notification type, particular application(s), and/or particular user contacts. When a shutdown is initiated, a check is performed to determine whether any designated notifications are available. Then, available notifications may be exposed in various ways prior to complete shutdown, such as by showing the notifications as part of a user interface(s) for the shutdown sequence.
