NFC Tag System for Multi-Function Wireless Connection and Data Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current NFC technology allows only one function to be implemented by reading an NFC tag on a device, resulting in low interaction efficiency, as multiple functions cannot be simultaneously executed through a single touch.
Innovation Solution
A near field communication system that enables multiple functions to be implemented by establishing wireless connections between an NFC-enabled device and multiple NFC-tagged devices, using connection information stored in the tags to synchronize audio or video data, allowing for stereo output or projection, based on user intention determined by scenario information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only one function is implemented by reading an NFC tag, then the system complexity is low, but the interaction efficiency is low
Solution Approach 1:
The NFC tag system is designed to support multiple functions simultaneously through a single touch. The first electronic device can establish wireless connections to multiple second electronic devices (e.g., audio device and video device) by reading different NFC tags, enabling functions such as stereo audio output and video projection to be implemented through one interaction action.
2Ease of operation
If multiple functions are implemented through one touch, then the interaction efficiency is improved, but the device complexity increases
Solution Approach 1:
The system segments different functions into separate NFC tags stored in the first electronic device. Each NFC tag corresponds to a specific second electronic device or function type. By organizing functions this way, the system can selectively activate appropriate functions based on the NFC tag read, managing complexity through structured organization rather than monolithic integration.
Solution Approach 2:
The NFC tag acts as an intermediary that stores connection information and triggers appropriate wireless connections. This intermediary mechanism simplifies the interaction between the first electronic device and multiple second electronic devices, allowing the system to handle multiple functions without requiring complex direct connection management from the user perspective.
3Ease of operation
If connection information is stored in NFC tags, then the ease of operation is improved, but the quantity of information stored increases
Solution Approach 1:
The connection information is extracted and stored in separate NFC tags rather than being stored comprehensively in the first electronic device's internal memory. This extraction approach reduces the information burden on the main device while maintaining ease of operation, as the NFC tags serve as portable information carriers that can be read and processed when needed.

Implementation Method 1
NFC is a near field communication technology based on a carrier frequency of 13.56 megahertz (MHz), and allows non-contact point-to-point data transmission between devices
Implementation Method 2
send first audio channel data to the second electronic device through the first wireless connection, and send second audio channel data to the third electronic device through the second wireless connection
Data Source
AI summary
A method includes after a user touches a near-field communication (NFC) tag on a second electronic device using a first electronic device having an NFC function, a plurality of functions can be implemented simultaneously. For example, after the user holds a mobile phone to touch an NFC tag on a television, the mobile phone establishes a wireless connection to the television, and synchronizes a video being played on the mobile phone with the television for playing.
