Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication device sends different information based on error state, then error handling capability is improved, but device complexity increases
Solution Approach 1:
The communication device dynamically changes the information sent through NFC interface based on its operational state. In error states, it sends error state information to enable error handling, while in non-error states, it sends wireless profile information to enable connectivity. This dynamic adaptation resolves the contradiction by making the system flexible rather than static.
Solution Approach 2:
The patent changes the parameter of information content based on the device's error state. By monitoring the error state and adjusting what information is transmitted through NFC, the system achieves improved error handling without requiring complex additional hardware, as it leverages existing NFC infrastructure with adaptive content.
2Adaptability or versatility
If the communication device uses multiple communication interfaces, then communication versatility is improved, but device complexity increases
Solution Approach 1:
The communication device employs multiple communication interfaces (NFC and wireless communication interfaces like Wi-Fi) to serve different functional needs. NFC is used for initial connection and information exchange, while wireless interfaces handle data transmission. This multi-functionality approach improves communication versatility by allowing the device to operate in different modes depending on availability and requirements.
Solution Approach 2:
The NFC interface acts as an intermediary that facilitates the establishment of wireless connections. By using NFC to first establish proximity and exchange connection information, the system enables seamless wireless communication without requiring complex pairing protocols, thus improving versatility while managing complexity through a staged communication approach.
3Loss of time
If the communication device sends wireless profile information, then connection establishment speed is improved, but information security risks increase
Solution Approach 1:
The wireless profile information is prepared and stored in advance in the communication device, allowing for rapid connection establishment when needed. By having connection parameters pre-configured and ready to transmit through NFC, the system achieves fast connection setup without requiring real-time negotiation, thus reducing time loss while maintaining security through controlled information release.
Solution Approach 2:
The system transmits a copy of the wireless profile information through NFC rather than the actual sensitive authentication data. This allows the portable terminal to establish wireless connections quickly using the transmitted profile copy, while the original secure credentials remain protected in the communication device, thus balancing speed with security.

AI summary
A communication device may comprise a first interface used by executing a wireless communication. The communication device may perform: in a case where a first connection via the first interface is established with the portable terminal under a circumstance where the communication device is in an error state, sending related information to the portable terminal by using the first connection via the first interface, the related information being related to the error state; and in a case where a second connection via the first interface is established with the portable terminal under a circumstance where the communication device is in a non-error state, sending different information to the portable terminal by using the second connection via the first interface, the different information being different from the related information.
