Solution Overview
Problem
Existing communication devices face challenges in seamlessly switching between different wireless communication standards, such as NFC and Wi-Fi Direct, which limits their ability to efficiently communicate with mobile devices across various networks without requiring access points.
Innovation Solution
A communication device equipped with multiple interfaces (NFC and Wi-Fi) that can operate in different states, allowing it to communicate with mobile devices using either standard without an access point or through one, and manage network settings to include or exclude passwords based on the network type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication device uses a single wireless communication interface, then the device complexity is reduced, but the adaptability to different wireless networks and communication standards deteriorates
Solution Approach 1:
The communication device is equipped with multiple wireless communication interfaces (first wireless communication interface and second wireless communication interface) that support different communication standards and network types. This multi-functional design enables the device to adapt to various wireless networks and communication scenarios without requiring separate dedicated devices for each function.
2Reliability
If the communication device always includes password in wireless settings, then the security is improved, but the ease of connection to open networks deteriorates
Solution Approach 1:
The wireless setting information is dynamically adjusted based on the detected network type. When a protected network is detected, password information is included in the setting; when an open network is detected, the setting excludes password information. This dynamic adaptation allows the device to maintain security where needed while enabling easy connection to open networks.
Solution Approach 2:
The patent changes the parameter of whether to include password information in wireless settings based on network conditions. The control unit modifies the wireless setting information's content (including or excluding password) according to the type of network detected, thereby adapting the security parameter to the operational context.
3Adaptability or versatility
If the communication device switches between different wireless communication standards, then the adaptability is improved, but the stability of communication connection deteriorates
Solution Approach 1:
The control unit detects the network type in advance before establishing communication and determines whether to include password information in the wireless setting beforehand. This preliminary detection and preparation ensures that the appropriate setting is already ready when communication needs to be established, preventing connection failures and maintaining stability during standard switching.

AI summary
In a case where a communication device belongs to a first wireless network for the communication device to execute a wireless communication, the communication device may execute using a wireless communication with a mobile device via the first wireless network after sending to the mobile device a first wireless setting. The first wireless setting may be for the mobile device to belong to the first wireless network and include a password. In a case where the communication device belongs to a second wireless network for the communication device to execute a wireless communication, the communication device may execute a wireless communication with the mobile device via the second wireless network after sending to the mobile device a second wireless setting. The second wireless setting may be for the mobile device to belong to the second wireless network and not including the password.
