Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication device uses a single wireless interface for communication, then the device complexity is reduced, but the adaptability to different wireless communication standards and network configurations is limited
Solution Approach 1:
The communication device incorporates multiple wireless interfaces (first wireless interface for NFC and second wireless interface for Wi-Fi Direct) that enable the device to operate across different wireless communication standards and network configurations. This multi-functionality allows the device to adapt to various communication scenarios without requiring separate dedicated devices for each standard.
2Adaptability or versatility
If the communication device switches between different wireless communication standards, then the adaptability improves, but the communication reliability and seamless transition are compromised
Solution Approach 1:
The control unit acts as an intermediary that manages the switching between different wireless interfaces. It determines the appropriate interface based on network configuration and executes the switching process, ensuring that transitions between NFC and Wi-Fi Direct are handled systematically. This mediation maintains communication reliability by coordinating the switch rather than allowing arbitrary transitions.
3Adaptability or versatility
If the communication device operates in multiple states (parent station, child station, device state), then the versatility of wireless network operation is improved, but the device complexity increases
Solution Approach 1:
The communication device dynamically transitions between different operational states (parent station state, child station state, and device state) based on the requirements of the wireless network and communication scenario. The control unit manages these state transitions, allowing the device to adapt its role in the network dynamically rather than being fixed in a single operational mode.
4Productivity
If the communication device uses dual interfaces for wireless communication, then the communication speed and reliability are improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The communication device integrates multiple wireless interfaces (NFC and Wi-Fi Direct) that provide different communication capabilities. The second wireless interface (Wi-Fi Direct) enables faster data transmission for high-speed communication needs, while the first wireless interface (NFC) provides reliable short-range communication for initial connection and configuration. This multi-functional approach optimizes communication speed without requiring separate dedicated devices.

AI summary
A communication device may execute a specific wireless communication of object data via a first wireless network with a mobile device using a second type of interface after executing a specific process of sending a first wireless setting for causing the mobile device to belong to the first wireless network using a first type of interface in a first case where the communication device operates in a first state which is a parent station state or a child station state in the first wireless network and execute the specific wireless communication of the object data with the mobile device using the second type of interface after executing another process different from the specific process in a second case where the communication device operates in a second state which is different from the first state.
