Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If NFC devices are separated and repositioned for each data transmission, then data communication can be established, but communication efficiency deteriorates and time is lost due to repeated setup procedures
Solution Approach 1:
The patent applies preliminary action by establishing a continuous communication mode where devices perform device checking and data transfer procedures only once initially. After the initial setup, the magnetic field is maintained and devices can continuously transmit and receive data without repeated separation and repositioning, thereby eliminating repetitive setup time and improving overall communication efficiency.
2Quantity of substance
If multiple short data transmissions are performed, then large-capacity data can be transferred, but the number of communication iterations increases causing inconvenience
Solution Approach 1:
The patent implements continuity of useful action by enabling continuous data transmission mode where, after initial device checking, the NFC devices maintain an active magnetic field and can continuously transfer large-capacity data without requiring repeated setup procedures. This continuous mode eliminates the need for multiple separate transmission operations, significantly improving ease of operation while maintaining large data capacity transfer capability.
3Quantity of substance
If NFC communication is used for large-capacity data, then cable-based communication functionality is achieved, but repeated device manipulation is required
Solution Approach 1:
The patent reduces communication procedure complexity by performing device checking, mode determination, and parameter setup only once during initial connection. The established continuous communication mode allows large-capacity data transfer without requiring repeated device manipulation or setup procedures, thereby simplifying the overall communication process while maintaining cable-like data capacity.
Solution Approach 2:
The patent eliminates repeated device manipulation by implementing continuous communication mode where devices maintain an active magnetic field and can continuously transfer data without requiring repeated separation, repositioning, or setup procedures. This continuous operation simplifies the communication procedure while enabling large-capacity data transfer comparable to cable-based communication.

AI summary
An electronic device includes a communication interface operable to perform contactless communication with an external device; and a processor operable to control to determine a communication type to be performed with the external device; when the communication type is a first type of continuous communication, configure data in a long packet structure; when the communication type is a second type of discontinuous communication, configure data in a short packet structure; and perform data communication in the continuous communication or in the discontinuous communication with the external device on the basis of the determined communication type.
