BLE Hands-Free Notification Routing Across Multiple User Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hands-free functionality in electronic devices is limited to a single user terminal device and does not support notifications from multiple devices, particularly when different accounts are involved.
Innovation Solution
An electronic device equipped with a communication interface and processor that can receive Bluetooth low energy packets, identify pre-registered external devices, establish connections, and execute hands-free functionality to control notifications from multiple user terminal devices, including those with different accounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hands-free functionality is limited to a single user terminal device, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The electronic device is designed to universally connect with and manage multiple user terminal devices simultaneously, not limited to a single device. The system can identify, connect to, and manage notifications from multiple external devices through standardized BLE communication protocols, enabling one device to serve multiple functions and users.
Solution Approach 2:
The connection management system is segmented into independent connection modules, each handling a specific external device. The processor can maintain separate connection states and notification management channels for different devices, allowing independent management of each device connection while operating within a unified system framework.
2Adaptability or versatility
If the electronic device connects to multiple user terminal devices, then adaptability improves, but connection management complexity increases
Solution Approach 1:
External devices perform self-identification by broadcasting their device information through BLE packets. The electronic device automatically identifies and processes these packets without requiring manual configuration, reducing the complexity of connection management. The system autonomously handles device discovery, identification, and connection establishment.
Solution Approach 2:
BLE packets serve as an intermediary mechanism between multiple external devices and the electronic device. These standardized packets facilitate automatic device identification and connection requests, acting as a mediator that simplifies the interaction protocol and reduces management complexity compared to custom or manual connection methods.
3Productivity
If hands-free functionality responds to notifications from multiple devices, then productivity improves, but ease of operation deteriorates
Solution Approach 1:
The electronic device displays notifications from multiple external devices on its own display interface, creating a centralized copy of notification information. Users can view and respond to notifications from different devices through a single unified interface on the electronic device, eliminating the need to switch between multiple device interfaces while maintaining ease of operation.

AI summary
An electronic device includes one or more processors and memory storing instructions. The instructions, when executed by the one or more processors, cause the electronic device to receive a first Bluetooth low energy (BLE) packet including first identification information, identify a first external device based on the first identification information, transmit a second BLE packet based on the identification of the first external device as a pre-registered device, based on a connection request being received from the first external device according to the transmission of the second BLE packet, perform a first connection between the electronic device and the first external device, and execute a first hands-free functionality of controlling a first notification, intended to be output by the first external device, to be output by the electronic device, based on the first connection of the electronic device with the first external device.
