NFC-Triggered Wireless File Sharing for Museums
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies, such as Bluetooth, face challenges in efficiently sharing information contents between electronic devices without causing 'spam' phenomena and require cumbersome activation steps, especially in scenarios like fairs or museums where selective file transfer is needed.
Innovation Solution
An NFC-based 'stand-alone' device with a communication module implementing Peer-to-Peer mode, allowing automatic file transfer without explicit user commands, using a combination of NFC and potentially higher-rate protocols like Bluetooth for efficient data exchange, reducing setup times and preventing unwanted content sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If Bluetooth protocol is used for wireless file sharing, then transmission rate is improved (higher than 3 Mbit/s), but connection setup time increases and user configuration complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring the stand-alone device with NFC technology and file content before the actual file transfer needs to occur. The device is prepared in advance with the capability to automatically detect and connect to electronic devices via NFC, eliminating the need for real-time configuration during file sharing operations.
Solution Approach 2:
The patent uses NFC technology as an intermediary to establish initial contact and trigger the file transfer process. The NFC interaction serves as a mediator that initiates the subsequent Bluetooth connection and file transfer, separating the configuration-free initial contact from the actual data transmission phase.
2Speed
If Bluetooth protocol is used for wireless file sharing, then transmission rate is improved (higher than 3 Mbit/s), but device complexity increases due to configuration requirements
Solution Approach 1:
The stand-alone device with NFC capability performs self-service by automatically detecting electronic devices in proximity, initiating connections, and managing file transfers without requiring user configuration. The device autonomously handles the complexity of connection management, protocol selection, and transfer initiation based on NFC-triggered events.
Solution Approach 2:
The stand-alone device is designed with multi-functionality, supporting both NFC for initial contact and Bluetooth for high-speed transfer. This universal design allows the device to handle multiple communication protocols and operate in various scenarios (information sharing, file transfer, device pairing) without requiring different specialized devices or complex user configuration.
3Adaptability or versatility
If continuous sending of documents to all users in communication range is performed, then information sharing coverage is improved, but harmful spam phenomena occur
Solution Approach 1:
The patent applies local quality by making the information sharing targeted and location-specific through NFC proximity detection. Instead of broadcasting to all devices in range, the system selectively shares information only with devices that are physically close to and have interacted with the stand-alone device via NFC, creating localized, context-appropriate sharing zones.
Solution Approach 2:
The system uses feedback from NFC interaction to control the file transfer process. The NFC detection and user interaction serve as feedback signals that trigger and regulate the subsequent Bluetooth file transfer, ensuring that files are only sent when there is explicit user intent and proximity confirmation, thereby preventing unwanted spam transmissions.
