Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of the Bluetooth pairing process between a vehicle's head unit and a mobile terminal, requiring more than six steps, hinders user convenience and efficiency.
Innovation Solution
A method and system that utilize a single wired connection to obtain pairing information, which is then stored on an NFC tag, simplifying the pairing process by enabling the transmission and storage of necessary information, such as the infotainment system's MAC address or Bluetooth module details, and allowing for automatic installation of a dedicated APP to facilitate NFC-based pairing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional Bluetooth pairing procedure is used between a head unit and a mobile terminal, then the pairing can be established, but the process requires more than six steps making it complex and inconvenient for users
Solution Approach 1:
The patent applies preliminary action by pre-storing Bluetooth pairing information (such as MAC addresses) in an NFC tag within the vehicle's infotainment system before the user needs to pair devices. When a user wants to pair a mobile terminal, they simply need to tap the NFC tag with their smartphone, and the pre-stored Bluetooth pairing information is automatically retrieved and used to establish the connection, eliminating the need for manual step-by-step pairing procedures.
Solution Approach 2:
The patent introduces an NFC tag as an intermediary element that facilitates the pairing process. Instead of directly pairing Bluetooth devices through complex procedures, the NFC tag serves as a mediator that contains and transfers pairing information between the vehicle's infotainment system and the mobile terminal, simplifying the interaction to a single tap operation.
2Reliability
If a complex multi-step pairing procedure is implemented, then comprehensive pairing information can be exchanged, but the ease of operation deteriorates due to the number of steps required
Solution Approach 1:
The system performs preliminary action by pre-configuring and storing accurate Bluetooth pairing information (including MAC addresses and other connection parameters) in the NFC tag during vehicle setup or previous pairings. This ensures that when pairing is needed, the information is already verified and stored correctly, maintaining reliability while simplifying the user operation to a single NFC tap.
Solution Approach 2:
The patent uses copying by creating a duplicate of the Bluetooth pairing information and storing it in the NFC tag. This copy contains all necessary pairing data, allowing the system to retrieve and use this copied information for快速 pairing without requiring the user to go through the complete original pairing procedure again, thus maintaining information accuracy while improving operational simplicity.

Function Achieved in This Case
This approach streamlines the Bluetooth pairing process by reducing it to a single wired connection and NFC tagging, eliminating the need for complex step-by-step procedures, thereby enhancing user convenience and efficiency in pairing devices.
Implementation Method 1
storing the information to a NFC (Near Field Communication) tag by the dedicated APP
Implementation Method 2
obtaining, by the controller, the information via the tagging by the mobile terminal
Data Source
AI summary
A Bluetooth pairing method is provided which includes connecting a mobile terminal and an infotainment system of a vehicle by a wired connection. The method also includes executing a dedicated APP (application) for a Bluetooth pairing disposed in the mobile terminal by a controller disposed in the infotainment system. Information regarding the infotainment system for the Bluetooth pairing is transmitted to the dedicated APP by the controller and the information is stored to a NFC (Near Field Communication) tag by the dedicated APP.
