Multi-OS Device Notification Handling via External Delegate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-operating system devices cannot output notifications associated with an operating system in the background, leading to resource wastage and inability to suspend or turn off the background OS without losing notification handling capabilities.
Innovation Solution
A multi-operating system device with a processor hosting a foreground OS and a background OS, where the processor communicates with a notification device using signals to handle and output notifications for the background OS, allowing the foreground OS to control output devices and manage notifications, even when the background OS is inactive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the background OS is suspended or turned off to save resources, then energy consumption and resource usage are reduced, but the ability to receive and output notifications for the background OS is lost
Solution Approach 1:
The notification handling function is segmented from the background OS and relocated to the notification device. The background OS can be suspended or turned off while the notification device independently receives and manages notifications for it, separating the OS execution from notification handling responsibilities.
Solution Approach 2:
The notification device acts as an intermediary between the background OS and the user. It receives notifications intended for the background OS, stores them, and outputs them when the user activates the foreground OS, mediating the communication gap when the background OS is inactive.
2Reliability
If the background OS remains active to maintain notification handling capability, then notification capabilities are preserved, but system resources are wasted
Solution Approach 1:
The notification handling capability is extracted from the background OS and transferred to the notification device. This allows the background OS to be completely suspended or turned off without compromising notification handling, as this function now resides externally in the notification device.
Solution Approach 2:
The notification device provides self-service notification handling for the background OS. It independently receives, manages, and outputs notifications without requiring the background OS to remain active, enabling resource-efficient operation while maintaining full notification functionality.
3Ease of operation
If the foreground OS controls the output device to display notifications, then the foreground OS maintains control over user interface, but notifications from the background OS cannot be displayed when it is in the background
Solution Approach 1:
The notification device performs preliminary action by receiving and storing notifications for the background OS before the user switches to the foreground OS. When the foreground OS is activated, the notification device outputs these pre-captured notifications, ensuring no information is lost despite the background OS being inactive.
Solution Approach 2:
The notification device maintains continuous notification handling capability across OS transitions. It continuously receives notifications for the background OS and ensures their output when the foreground OS is active, maintaining the continuity of useful notification delivery without interruption from OS state changes.
