Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual application selection is implemented after hardware connection, then application compatibility and user control are improved, but operation complexity and time consumption increase
Solution Approach 1:
The patent pre-configures intent filters and metadata in the application package during the application development phase. These pre-configured elements contain device information and communication parameters that enable automatic application initiation when the USB device is connected, eliminating the need for manual selection and reducing time loss.
Solution Approach 2:
The system automatically matches USB devices with corresponding applications using pre-configured intent filters and metadata without requiring user intervention. The terminal device autonomously completes the application initiation process by comparing device information with stored configurations, making the system self-serving and improving ease of operation.
2Reliability
If hardware re-connection is required for OTG communication, then communication reliability is improved, but operation complexity and user experience deteriorate
Solution Approach 1:
The patent replaces the mechanical hardware re-connection process with an automatic software-based matching system. By using intent filters and metadata to automatically initiate applications and establish OTG communication, the system eliminates the need for manual hardware manipulation while maintaining communication reliability through pre-configured connection parameters.
3Productivity
If automatic application initiation is implemented, then productivity and user experience are improved, but system complexity and configuration difficulty increase
Solution Approach 1:
The patent uses a universal intent filter and metadata structure that can be applied to multiple applications and USB device types. This standardized configuration approach allows the system to handle diverse OTG communication scenarios through a unified mechanism, improving productivity while managing system complexity through reuse of common structures.

AI summary
A method for realizing OTG communication without plugging and unplugging includes: when an apk file of an application is generated, the application presets device information of an associated USB device; when the USB device is connected to a terminal device, a system of the terminal device recognizes an application qualified for initiation according to the device information of the connected USB device; a target application is initiated according to the application qualified for initiation and a user selection result; and the target application initiates a processing thread so as to establish OTG data communication with the connected USB device. The present disclosure realizes that after the USB device is plugged, the corresponding target application on the terminal device is initiated, and the terminal device and the USB device can directly perform OTG communication without the need of hardware connection of the USB device with the terminal device again, thereby avoiding the processing of manually selecting the target application, improving the initiation efficiency, and improving the usage feeling of the user. The disclosure also relates to an apparatus, terminal device and medium for realizing OTG communication without plugging and unplugging.
