Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transferring streaming media information between devices, such as those using ultra wide band (UWB) sensors and near field communication (NFC), are limited by hardware requirements and short distance ranges, leading to a poor user experience.
Innovation Solution
A data transfer method involving camera modules on multiple devices to collect image data, determine a source and target device based on gestures, and transfer content between them without additional hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UWB sensors and NFC are used for data transfer, then data transfer between devices is enabled, but hardware requirements increase and distance range is limited
Solution Approach 1:
The patent extracts the data transfer function from specialized hardware (UWB sensors, NFC tags) and implements it using general-purpose camera modules that are already present in most devices. This eliminates the need for additional hardware while maintaining data transfer capability.
Solution Approach 2:
The camera module, originally designed for imaging, is made multi-functional by enabling it to perform both image capture and data transfer identification. This universal approach allows existing hardware to serve multiple purposes without requiring specialized components.
2Adaptability or versatility
If UWB sensors and NFC are used for data transfer, then data transfer between devices is enabled, but distance range is limited to short range
Solution Approach 1:
The patent replaces the mechanical/close-contact based UWB and NFC systems with an optical system using camera modules. This substitution enables long-distance communication by using visual recognition and image processing to identify devices and transfer data without physical proximity constraints.
3Device complexity
If camera modules are used for data transfer identification, then hardware requirements are reduced and distance range is extended, but image data processing complexity increases
Solution Approach 1:
The patent performs preliminary actions by pre-processing image data to extract key features and identifiers before the actual data transfer process. This preparation step simplifies the subsequent recognition and identification processes, making the system more efficient despite the increased processing requirements.

AI summary
A data transfer method and an electronic device are provided. The method includes: controlling camera modules of N devices to collect first image data in response to a triggering instruction, where N is a natural number greater than or equal to 2; determining a source device in the N devices based on the first image data; controlling camera modules of N-1 devices other than the source device to collect second image data; determining a target device in the N-1 devices based on the second image data; and controlling the source device for transferring a target content to the target device.
