NFC Media Content Transfer for Low-Data Cross-Device Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing applications require users to download media content multiple times, consuming significant data traffic, which is inefficient and costly.
Innovation Solution
Establishing a near field communication connection between terminal devices to transfer cached media content, allowing users to share media content without using data traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If users download media content through traditional network methods, then they can access media content, but they consume significant data traffic which is inefficient and costly
Solution Approach 1:
The patent introduces near field communication as an intermediary transmission channel between terminal devices. Instead of directly downloading media content through traditional network methods, the system uses near field communication connections as a mediator to transfer cached media content between devices, thereby reducing data traffic consumption while maintaining access convenience
Solution Approach 2:
The patent implements a copying mechanism where media content cached on one terminal device is copied to another terminal device through near field communication. This allows users to access media content on multiple devices without re-downloading, thus reducing overall data traffic consumption while maintaining ease of access
2Loss of energy
If users cache media content locally, then they can view content without data usage, but the content can only be viewed on that specific device
Solution Approach 1:
The patent makes the media content caching system universal across multiple terminal devices. By enabling near field communication between devices, a single cache on one device becomes accessible from multiple devices, thus achieving cross-device content accessibility while maintaining the data-saving benefit of local caching
Solution Approach 2:
Near field communication serves as an intermediary mechanism that bridges the gap between local caching and cross-device accessibility. It enables the transfer of cached content between devices without requiring traditional network downloads, thus maintaining data efficiency while achieving versatility
3Adaptability or versatility
If traditional network methods are used for content sharing, then content can be transferred between users, but significant data traffic is consumed
Solution Approach 1:
The patent replaces traditional network-based content sharing with near field communication as an intermediary transmission method. This allows content to be shared between users through direct device-to-device communication, eliminating the need for content to traverse the traditional network infrastructure and thus reducing data traffic consumption
Solution Approach 2:
The patent implements a copying-based content sharing mechanism where media content is copied from one terminal device to another through near field communication. This copying approach allows content sharing without traditional network downloads, reducing data traffic consumption while maintaining sharing capability

AI summary
A method for content interaction is provided. The method include establishing, at a first terminal device corresponding to a first user of an application, a near field communication connection between the first terminal device and a second terminal device corresponding to a second user of the application in response to a detection of a content transfer request for the second user; presenting a content transfer panel, the content transfer panel presenting a media content list cached by the application at the first terminal device; and transmitting one or more items of media content from the first terminal device to the second terminal device via the near field communication connection in response to receiving a selection of the one or more items of media content in the media content list.
