Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth device list is searched by device name, then connection can be established, but user experience deteriorates due to difficulty in identifying devices with modified names and lengthy lists
Solution Approach 1:
The patent introduces spatial dimensions (distance and azimuth) to the traditional one-dimensional device name search. By capturing the spatial position of the target device and matching it with Bluetooth devices at corresponding positions, the system transforms the search from name-based to position-based, enabling rapid identification even when device names are modified or generic.
2Adaptability or versatility
If all Bluetooth devices are displayed in the device list, then complete device selection is enabled, but device list complexity increases making searching difficult
Solution Approach 1:
The patent extracts the target device from the complex Bluetooth device list by using spatial position information. Instead of presenting the user with the entire device list, the system captures the position of the target device and extracts only the matching device information, thereby simplifying the interface while maintaining complete device selection capability.
3Productivity
If manual device name searching is performed, then connection can be established, but operation complexity increases and efficiency decreases
Solution Approach 1:
The patent implements self-service by enabling the terminal device to automatically capture the spatial position of the target device through camera or sensor, automatically search for matching Bluetooth devices based on position information, and automatically establish connection. This eliminates the need for manual device name searching and significantly improves both operation simplicity and connection efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary
A method includes: A terminal device determines a first device in an image displayed on a capture screen, and obtains a first distance and a first azimuth; and searches a Bluetooth device list for a Bluetooth device matching the first distance and the first azimuth, and establishes a wireless connection to the matched Bluetooth device, where the first distance is a distance between the terminal device and the first device, and the first azimuth is an azimuth of the first device relative to the terminal device. According to this method, the Bluetooth device list is searched for the matched Bluetooth device only by using the first distance and the first azimuth. This prevents a user from searching, by using a device name, the Bluetooth device list for a device that needs to be connected.
