Solution Overview
Problem
Existing communication devices struggle to seamlessly switch between different wireless communication protocols such as NFC, Wi-Fi Direct, and normal Wi-Fi, leading to inefficiencies and limitations in data transfer speeds and compatibility with both WFD-compatible and WFD-incompatible devices.
Innovation Solution
A communication device equipped with multiple interfaces (NFC, WFD, and normal Wi-Fi) that dynamically adjusts its network membership and settings to facilitate efficient data transfer by determining its and the mobile device's network status, allowing it to switch between different wireless communication protocols, including spontaneous G/O mode, to establish connections with both WFD-compatible and WFD-incompatible devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication device uses multiple wireless communication interfaces (NFC, WFD, normal Wi-Fi) to improve compatibility and data transfer efficiency, then the device complexity increases
Solution Approach 1:
The communication device is equipped with multiple wireless communication interfaces (NFC interface, WFD interface, and normal Wi-Fi interface) that enable it to communicate with various types of devices using different protocols. This multi-functionality allows a single device to serve multiple communication purposes and work with both WFD-compatible and WFD-incompatible devices.
Solution Approach 2:
The NFC interface acts as an intermediary for initial connection and information exchange between devices. Through NFC, devices can exchange connection information and establish subsequent WFD or normal Wi-Fi connections, simplifying the overall connection process despite having multiple interfaces available.
2Speed
If the communication device dynamically switches between different wireless communication protocols to improve data transfer speed, then the network management complexity increases
Solution Approach 1:
The communication device dynamically determines network membership status and automatically switches between different wireless communication protocols (NFC, WFD, normal Wi-Fi) based on real-time network conditions. This dynamic adaptation allows the device to optimize data transfer speed by selecting the most appropriate protocol for each situation.
Solution Approach 2:
The device continuously monitors its network membership status and uses this feedback information to determine which communication protocol to use. By checking whether it belongs to a WFD network or normal Wi-Fi network, the device can make informed decisions about protocol selection and automatically adjust its communication method.
3Ease of operation
If the communication device uses NFC for initial connection to improve ease of operation, then the overall communication efficiency may be reduced due to protocol switching
Solution Approach 1:
The NFC interface is used to perform preliminary actions by establishing initial contact and exchanging connection information between devices. This preliminary connection enables subsequent faster WFD or normal Wi-Fi communication, making the overall process both easy to operate and efficient.
Solution Approach 2:
The system maintains continuous useful action by seamlessly transitioning from NFC-based initial connection to WFD or normal Wi-Fi-based data transfer. This continuity ensures that the ease of NFC connection establishment is combined with the high efficiency of WFD/normal Wi-Fi data transmission, avoiding interruptions in the communication process.
