Notification Management for Wearable Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices, such as smart watches and smart glasses, face battery drain issues due to frequent notifications, leading to reduced usage time and inefficient battery consumption.
Innovation Solution
Implementing a power saving method where electronic devices communicate using Bluetooth Low Energy (BLE) to reduce unnecessary notifications based on user wear status and notification limiting times, allowing devices to enter power saving modes when battery levels are low or when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If frequent notifications are sent to portable electronic devices, then users can stay informed about events and messages, but battery consumption increases and operational time decreases
Solution Approach 1:
The patent introduces a notification management system that acts as an intermediary between the notification source and the portable device. This system monitors device state (wearing status, battery level) and selectively blocks notifications based on these conditions, thereby reducing unnecessary battery consumption while still delivering important information when appropriate.
Solution Approach 2:
The system dynamically changes the notification delivery parameter based on device state. When the device is not being worn or battery level is low, notification delivery is restricted. When the device is being worn and battery level is sufficient, normal notification delivery resumes. This conditional parameter adjustment resolves the contradiction between information delivery and energy conservation.
2Duration of action of moving object
If notifications are restricted based on wearing status and battery level, then battery life is extended, but users may miss important information
Solution Approach 1:
The notification restriction system is dynamic rather than static. It continuously monitors device state (wearing status via sensors, battery level via power management circuit) and adjusts notification delivery in real-time. This dynamic approach ensures that information is not lost permanently, but temporarily withheld only when energy conservation is prioritized, resolving the contradiction between battery life extension and information delivery.
Solution Approach 2:
The system implements feedback mechanisms where the notification management module receives continuous feedback about device state (wearing status, battery level) and adjusts its behavior accordingly. This feedback loop ensures that notification delivery is optimized based on current conditions, preventing information loss while managing battery consumption effectively.
3Productivity
If devices continuously check wearing status and battery levels to manage notifications, then notification delivery is optimized, but additional processing increases power consumption
Solution Approach 1:
Instead of continuous monitoring, the system uses periodic checks at predetermined intervals to assess wearing status and battery level. This periodic action reduces the processing burden and associated power consumption compared to continuous monitoring, while still maintaining effective notification management. The system balances the need for timely notification decisions with the cost of continuous processing.

AI summary
An electronic device includes a communication unit and processing circuitry. The communication unit is configured to receive information on whether a user wears other electronic device. The processing circuitry configured to, responsive to a predetermined event occurring, determine whether the other electronic device is worn by the user. The processing circuitry also configured to control the communication unit to transmit a notification message to the other electronic device based on whether the other electronic device is in a worn state or an unworn state.
