Wearable Battery Status Transfer During Charging Disconnects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face difficulties in identifying and transmitting charging-related information of wearable devices, such as earbuds, when they are not connected to an external device, especially when they are being charged or mounted on a cradle, leading to challenges in monitoring battery status.
Innovation Solution
An electronic device equipped with a communication circuitry and memory that identifies charging status and connects via short-range wireless communication to an external device when a charging event occurs, transmitting charging-related information using protocols like Bluetooth, BLE, or Wi-Fi, even when the device is not directly connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wearable device is not connected to the external electronic device (e.g., when mounted on cradle or being charged), then the device can be charged or stored conveniently, but the charging-related information becomes difficult to identify on the external electronic device
Solution Approach 1:
The wearable device proactively transmits charging-related information to the external electronic device before the user needs to check the charging status. When a charging event is detected (device placed on cradle or connected to charger), the device automatically sends notifications about charging start, completion, or battery level, ensuring information is available even when not currently connected for active use.
2Measurement precision
If the wearable device maintains continuous connection to the external electronic device, then charging status can be monitored in real-time, but power consumption increases and connection stability may be compromised
Solution Approach 1:
Instead of maintaining continuous connection and real-time monitoring, the wearable device uses periodic action by detecting charging events (when charging starts or completes) and transmitting information only at these specific moments. This event-driven approach maintains accurate charging status monitoring while significantly reducing power consumption compared to continuous monitoring.
3Reliability
If the wearable device transmits charging information only when connected, then communication reliability is maintained, but information transmission is delayed when device is on cradle
Solution Approach 1:
The cradle serves as an intermediary device that bridges the wearable device and the external electronic device. When the wearable device is placed on the cradle for charging, the cradle receives charging status information from the wearable device and forwards it to the external electronic device, enabling information transmission even when the wearable device is not directly connected to the smartphone or other external device.

AI summary
An electronic device and method identifies a charging status, and based on the charging status satisfying a designated condition, identifies whether short-range wireless communication is connected with a designated external device. Based on identifying that the connection of the short-range wireless communication with the designated external device is released, the electronic device transmits a request for establishing a connection of the short-range wireless communication to the designated external device. Based on the connection of the short-range wireless communication with the designated external device being established, the electronic device transmits charging-related information to the designated external device through the communication circuitry.
