Terminal Device Content Transmission Without NFC Dependency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for content transmission between mobile phones and PCs are inefficient, relying on NFC functions, third-party applications, and data cables, requiring multiple operations and low efficiency.
Innovation Solution
A method where a terminal device can initiate content transmission without relying on NFC functions or NFC tags, by sending information about the type and recent operation of an interface to determine the content transmission direction, allowing for direct Bluetooth or Wi-Fi transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If NFC function and NFC tag are used for content transmission, then transmission efficiency is improved, but device complexity and applicability are reduced
Solution Approach 1:
The patent makes the second terminal device perform multiple functions: it acts as both a display device and a content transmission initiator. By enabling the second terminal device to send first information to the first terminal device and determine transmission direction, the system removes dependency on NFC functionality, making content transmission applicable to all terminal devices regardless of NFC capability.
2Ease of operation
If NFC tag is set on PC and NFC function is used, then content transmission is enabled, but device complexity increases
Solution Approach 1:
The patent extracts the NFC dependency from the content transmission system. Instead of requiring NFC tags and NFC functions, the solution uses a messaging mechanism where the second terminal device sends first information containing interface type and operation time to the first terminal device, which then determines transmission direction and executes content transfer without any NFC components.
3Productivity
If multiple operations are required for content transmission, then transmission can be performed, but user intervention increases and efficiency decreases
Solution Approach 1:
The patent implements preliminary action by having the second terminal device proactively send first information (including interface type and recent operation time) to the first terminal device before content transmission is requested. This pre-positioning of information enables the first terminal device to automatically determine transmission direction without requiring user intervention or multiple operational steps.
4Ease of operation
If third-party applications or data cables are used, then content transmission is achieved, but ease of operation is reduced
Solution Approach 1:
The patent implements self-service by enabling terminal devices to perform content transmission independently without external tools. The second terminal device sends first information to the first terminal device, which automatically determines transmission direction and executes the transfer using built-in communication capabilities, eliminating dependency on third-party applications or physical data cables.

AI summary
Embodiments of this application provide a content transmission method and a terminal device. The method includes: A first terminal device obtains a first instruction, where the first instruction indicates that the first terminal device needs to perform content transmission with another terminal device. The first terminal device sends first information to a second terminal device in response to the first instruction, where the first information is used by the second terminal device to determine that a content transmission direction is that the first terminal device transmits content to the second terminal device. The first terminal device receives content transmission direction indication information from the second terminal device. The first terminal device determines first content, and sends the first content to the second terminal device. The second terminal device receives and displays the first content. In this application, a terminal device triggers a content transmission process according to an instruction without depending on an NFC function, which achieves excellent applicability. In addition, this application does not depend on a third-party application, social software, or a data cable. In this case, content transmission is highly efficient and easy to implement.
