Native Drag-and-Drop File Transfer Between Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing file transfer methods between mobile terminals often require third-party instant messaging software, making the process inconvenient and resource-intensive, especially when transferring files between devices.
Innovation Solution
A file transfer method that detects a file drag operation and transfers data to a target device without the need for third-party software, using icon overlap or trigger events for detection and automatic connection establishment through pairing information, allowing for batch transfers and efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If third-party instant messaging software is used for file transfer, then file transfer can be achieved, but the operation process becomes complicated and requires additional software installation
Solution Approach 1:
The patent extracts the file transfer function from third-party instant messaging software and integrates it directly into the operating system. The system provides native drag-and-drop file transfer capability between devices, eliminating the need for external applications while maintaining the core file transfer functionality.
Solution Approach 2:
The operating system is enhanced with universal file transfer capability that works across different devices and scenarios. The same drag-and-drop interface handles various file types and transfer scenarios (single file, multiple files, different device types) without requiring specialized software for each case.
2Productivity
If continuous detection of file drag operation is performed, then file transfer can be initiated, but system resources are wasted
Solution Approach 1:
The system performs preliminary detection only when a file is selected by the user. Instead of continuous monitoring, the system waits for the user to explicitly select a file, then activates detection for the drag operation. This preliminary condition setup reduces unnecessary resource consumption while maintaining responsiveness when needed.
3Ease of operation
If target device icon is displayed all the time, then file transfer is convenient, but screen space is occupied and user is interfered during operation
Solution Approach 1:
The target device icon transitions from a static always-visible element to a dynamic element that appears and disappears based on user interaction. The icon is displayed only when a file is selected and remains visible during the drag operation, then disappears afterward. This dynamic behavior provides convenience when needed while freeing screen space during normal operation.

AI summary
The present invention relates to the field of communications, and more particular, to a file transfer method, a file transfer device, and a computer readable storage medium, and belongs to the field of terminal devices. The file transfer method includes: detecting (S11) a file drag operation for dragging an icon of a file onto an icon of a target device; acquiring (S12) data of the file in response to detecting the file drag operation, and sending (S13) the data to the target device. The file is transferred by dragging the file onto the icon of the target device, the process is simple. And a third-party instant messaging software is not required to be installed on the terminal device, and the file transfer process is simplified and is convenient to operate.
