Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for transferring files or data between mobile devices and PCs are time-consuming, cumbersome, and lack an intuitive solution, making them inefficient and inconvenient for users.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional file transfer methods (saving to file, establishing connection, dragging and dropping) are used, then data can be transferred between PC and mobile device, but the process is time-consuming and cumbersome
Solution Approach 1:
The patent replaces manual file operations (dragging, dropping, navigating) with camera-based optical targeting. The camera captures the PC screen, detects marker positions, and automatically determines coordinates for data transfer, substituting mechanical interaction with optical detection and automated processing.
Solution Approach 2:
The patent introduces markers as intermediary elements placed on the PC screen. These markers serve as reference points that the camera detects to establish coordinate mapping between the mobile device view and the PC screen, enabling precise targeting without manual intervention.
2Ease of operation
If manual file operations are used, then data transfer can be completed, but the operation is complex and not intuitive
Solution Approach 1:
The system performs automated coordinate calculation and data retrieval based on camera input. Once the user points the camera at the PC screen and captures an image, the system automatically processes the marker positions, calculates coordinates, and initiates data transfer without requiring the user to navigate through multiple manual steps.
Solution Approach 2:
The patent adds a spatial dimension to the data transfer process by using camera imaging. Instead of navigating through file systems or dragging files, the user simply points the camera at the desired location on the PC screen, transforming a multi-step navigation task into a single spatial targeting action.
3Measurement precision
If camera-based targeting is used, then precise positioning on PC screen is achieved, but image processing complexity increases
Solution Approach 1:
The patent pre-places markers with known positions on the PC screen before the data transfer process. These markers serve as reference points that simplify the image processing task, as the system only needs to detect the marker positions and calculate relative coordinates rather than performing complex screen mapping from scratch.

Function Achieved in This Case
Enables simple, rapid, and intuitive transfer of files or data between mobile devices and PCs, reducing the complexity and time required for data sharing by using camera-based targeting and image processing to determine coordinates on the PC screen.
Implementation Method 1
capturing, by the camera, a first image before the markers are placed on the screen, capturing, by the camera, a second image containing the markers

AI summary
A data transfer method, includes: identifying an object displayed on a screen of a second terminal by using a camera of a first terminal, to which data is to be transmitted; determining coordinates of the object identified by the first terminal; and transmitting the object displayed on the screen of the second terminal and/or its metadata to the first terminal.
