Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wired communication authentication using IP address is implemented according to DPP scheme, then authentication between terminal device and communication device can be executed, but detailed methods for other types of communication using IP address (such as wireless connection establishment) are not provided
Solution Approach 1:
The patent uses the existing wired communication authentication mechanism as an intermediary to enable wireless connection establishment. The terminal device first authenticates with the communication device via wired communication to obtain connection information, which then serves as a mediator to establish the wireless connection without requiring separate detailed protocols for wireless setup.
2Reliability
If manual device selection is required for wireless connection establishment, then connection security can be maintained, but operation complexity and time consumption increase
Solution Approach 1:
The patent performs preliminary authentication and connection information exchange through wired communication before wireless connection establishment. This preliminary action includes the terminal device sending an authentication request, receiving authentication response with connection information, and storing this information for later wireless connection use, thereby eliminating the need for manual device selection during wireless setup.
3Ease of operation
If wireless connection establishment process is simplified, then ease of operation improves, but the need for detailed authentication and connection management protocols increases system complexity
Solution Approach 1:
The patent extracts the complex authentication and connection management processes from the wireless connection establishment phase and places them in the wired communication phase. By separating these functions into distinct phases, the wireless connection setup becomes simple while the complex protocols are handled separately during initial wired authentication.

AI summary
A first terminal device may receive first address information which is a first IP address of the first communication device from the first communication device by using a communication network to which the first terminal device and a first communication device belong, and a first public key of the first communication device. The first terminal device may send a first authentication request in which the first public key is used to the first communication device with the first address information as a destination, and send first connection information to the first communication device with the first address information as a destination in a case where a first authentication response is received from the first communication device. The first connection information may be used by the first communication device to establish a first wireless connection between the first communication device and an external device.
