Bluetooth Display Switching Without Repeated Pairing Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inconvenience of registering a Bluetooth connection with a new device is a significant usability issue, as users must repeatedly input information during the pairing process.
Innovation Solution
A display device and wireless system that allow for the transmission of Bluetooth information between devices, enabling a seamless switch between connected devices without the need for re-registration, by receiving a device switching request, transmitting Bluetooth information, and disconnecting from the original device to reconnect with the new one based on that information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth connection is established with a new device, then connectivity is achieved, but users must repeatedly input information during the pairing process which is inconvenient
Solution Approach 1:
The system performs preliminary actions by storing Bluetooth information of display devices in advance. When a wireless device requests to switch connections, the target display device's Bluetooth information is already available in the system, eliminating the need for users to re-input pairing information and enabling seamless switching between devices.
2Ease of operation
If Bluetooth pairing process is simplified, then ease of operation is improved, but device switching functionality may be compromised
Solution Approach 1:
The system introduces an intermediary mechanism by maintaining a database of Bluetooth information for multiple display devices. This intermediary storage allows the wireless device to switch between different display devices seamlessly, as the system mediates the connection process by providing pre-stored Bluetooth information, thus preserving both simplicity and versatility.
3Speed
If Bluetooth information is transmitted between devices, then device switching speed is improved, but information security may be affected
Solution Approach 1:
The system uses copying by creating and storing copies of Bluetooth information (such as device identifiers and pairing data) in a centralized database. When device switching is needed, the system retrieves the appropriate copy rather than transmitting sensitive information in real-time, thus achieving fast switching while maintaining security by avoiding exposure of actual Bluetooth pairing credentials.
