Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method for multi-device Bluetooth connections is complex and time-consuming, requiring pairwise connections and multiple operations, which negatively impacts user experience and efficiency when connecting multiple devices.
Innovation Solution
A method that involves obtaining device information from a server, selecting devices based on user input, and using pairing requests and information to establish wireless connections, reducing the need for manual operations and simplifying the connection process by presenting device information for selection and using random numbers or keys for secure pairing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pairwise connection method is used for multi-device Bluetooth connections, then connection reliability is ensured through manual pairing, but operation complexity increases and connection time increases
Solution Approach 1:
The patent introduces a server as an intermediary to manage device pairing information. The server stores device information and pairing credentials, allowing devices to connect automatically without manual pairwise pairing. This resolves the contradiction by maintaining reliable connections through centralized management while eliminating complex manual operations at the device level.
Solution Approach 2:
The patent performs preliminary actions by pre-registering device information and pairing credentials on the server before actual device connections. When devices need to connect, the pairing process is already prepared and stored, eliminating the need for real-time manual pairing operations. This ensures connection reliability through pre-established credentials while greatly simplifying the actual connection operation.
2Reliability
If pairwise connection method is used for multi-device Bluetooth connections, then secure pairing is achieved through PIN code verification, but time consumption increases
Solution Approach 1:
The patent performs pairing security setup in advance by storing pairing credentials and PIN codes on the server during device registration. When actual device connections occur, the pre-stored pairing information is automatically retrieved and applied, eliminating the need for real-time PIN code entry and verification. This maintains pairing security through pre-established credentials while dramatically reducing connection time.
Solution Approach 2:
The server acts as an intermediary that manages secure pairing information centrally. Instead of requiring devices to perform time-consuming mutual verification through manual PIN entry, the server has already established and stored the pairing credentials. This allows rapid automated connections while maintaining the security that would otherwise require lengthy manual verification processes.
3Reliability
If multiple pairwise connections are performed for multi-device setup, then comprehensive device pairing is achieved, but user experience deteriorates due to repeated operations
Solution Approach 1:
The patent merges multiple pairwise connection operations into a single centralized registration process on the server. Instead of requiring users to perform repeated manual pairing operations between each device pair, all device information and pairing relationships are consolidated and managed on the server in one operation. This achieves comprehensive device pairing while dramatically improving user experience by eliminating repetitive manual steps.
Solution Approach 2:
The server serves as an intermediary that consolidates the management of multiple device pairings. Rather than requiring users to manually pair each device combination, the server centrally stores and manages all pairing information, automatically handling the complexity of multi-device relationships. This ensures complete pairing coverage while providing a simple, non-repetitive user experience.
