Display Device Bluetooth Connection Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with limited hardware or software resources face constraints in the number of Bluetooth devices that can be connected, and the types of external Bluetooth devices required vary depending on the applications being executed.
Innovation Solution
A display device and method that automatically release connections with external Bluetooth devices not required for the current application, allowing for the connection of devices needed based on the application being executed, and prioritizing frequently used devices by maintaining or releasing connections in order of usage frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the maximum number of Bluetooth devices are connected to the display device, then the availability of Bluetooth devices is improved, but the device complexity and resource management burden increase
Solution Approach 1:
The system automatically monitors application requirements and manages Bluetooth device connections without user intervention. The processor autonomously determines which devices should be connected or disconnected based on current application needs, eliminating the need for manual user management while maintaining optimal device availability
Solution Approach 2:
The Bluetooth device connection state is made dynamic rather than static. The system continuously adjusts the connected device list based on changing application requirements, allowing devices to be automatically connected or disconnected as needed, thereby adapting the system state to current operational demands
2Quantity of substance
If external Bluetooth devices are disconnected to make room for new devices, then the number of connectable devices is maintained, but the loss of information about previously connected devices occurs
Solution Approach 1:
The system maintains a paired device list that stores connection information of previously connected devices even after disconnection. This creates a persistent record (copy) of device information that can be quickly restored when needed, avoiding complete loss of connection data while managing active connection slots
3Adaptability or versatility
If Bluetooth connections are maintained for all paired devices, then connection availability is improved, but energy consumption increases
Solution Approach 1:
Instead of maintaining continuous Bluetooth connections, the system periodically assesses application requirements and adjusts connection states accordingly. Connections are maintained only during periods when the corresponding application is active and requires the device, and disconnected during periods when they are not needed, creating a periodic connect-disconnect pattern that reduces energy consumption
