Notification Message Handling in Sleep-State Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in reducing power consumption when receiving and processing notification messages, especially when the processor is in a sleep state, as they often require activation to process notifications, leading to increased power usage.
Innovation Solution
An electronic device with a processor, communication circuitry, and memory that can receive notification messages while in a sleep state, convert to an active state to process them, and then request and display subsequent messages, optimizing power usage by only activating when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first electronic device transmits notification messages to the second electronic device regardless of processor state, then notification delivery is ensured, but power consumption increases due to unnecessary processor activation
Solution Approach 1:
The patent changes the parameter of processor state (sleep vs. active) based on the type of notification message. The processor remains in sleep state for non-urgent notifications and only transitions to active state when urgent notifications require processing, thereby reducing unnecessary power consumption while ensuring reliable delivery of important notifications.
Solution Approach 2:
The patent implements preliminary classification of notification messages into urgent and non-urgent types before transmission. This preliminary action allows the system to prepare appropriate processing states in advance, avoiding unnecessary processor activation for non-urgent messages while ensuring urgent messages are handled promptly.
2Use of energy by moving object
If the processor remains in sleep state to save power, then power consumption is reduced, but notification messages cannot be received or processed
Solution Approach 1:
The patent segments notification messages into different categories (urgent and non-urgent) and processes them differently. The communication circuitry can receive messages in sleep state, and the processor is selectively activated only for urgent notifications, thus maintaining notification processing reliability for important messages while saving power overall.
Solution Approach 2:
The patent introduces a communication circuitry that acts as an intermediary between the external notification source and the processor. The communication circuitry can operate in low-power mode to receive notifications and selectively trigger processor activation only when necessary, bridging the gap between power saving and notification processing requirements.
3Productivity
If the processor is activated for every notification message, then all notifications are processed immediately, but battery life is reduced
Solution Approach 1:
The patent changes the processing parameter based on notification urgency. Non-urgent notifications are processed asynchronously or deferred, allowing the processor to remain in sleep state longer, while urgent notifications trigger immediate processing. This selective parameter change maintains productivity for important messages while extending battery life through reduced overall processor activation.
Solution Approach 2:
The patent implements periodic or event-driven processor activation rather than continuous operation. The processor is activated periodically or only when urgent notifications occur, rather than for every notification message. This periodic action pattern maintains necessary notification processing capability while significantly reducing power consumption and extending battery life.

AI summary
An electronic device includes a display, communication circuitry performing wireless connection with an external electronic device, a processor operatively coupled with the display and the communication circuitry, and a memory operatively connected with the processor. Based on executing instructions stored in the memory, the processor is configured to control the electronic device to receive information on a first notification message generated within the external electronic device using the communication circuitry. Based on instructions stored in the memory being executed, the processor controls the electronic device to display the first notification message through the display. Based on the instructions stored in the memory being executed, the processor is configured to control the electronic device to receive one or more second notification messages which have been generated within the external electronic device prior to the first notification message. Based on instructions stored in the memory being executed, the processor is configured to control the electronic device to display, in response to an input, the second notification message in at least a portion of the display.
