Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If initial connection setting procedure is performed for each electronic apparatus, then connection reliability is improved, but ease of operation deteriorates due to requiring multiple user operations
Solution Approach 1:
The system enables automatic identification and authentication of electronic apparatuses through image recognition. The terminal device captures an image of the electronic apparatus display, extracts feature information, and automatically performs authentication without requiring manual user input for each connection setting, thus improving ease of operation while maintaining connection reliability
Solution Approach 2:
The patent replaces manual mechanical connection setting operations with automated image recognition and feature extraction processes. Instead of requiring users to manually configure connections, the system uses visual recognition to automatically identify and authenticate apparatuses, streamlining the connection process
2Reliability
If authentication processes are performed for each reconnection, then security is improved, but ease of operation deteriorates due to repeated authentication requirements
Solution Approach 1:
The system performs authentication in advance by capturing and storing feature information of electronic apparatuses during initial connection. When reconnection is needed, the stored feature information is used to quickly verify and authenticate the apparatus again, eliminating the need for repeated manual authentication processes while maintaining security
Solution Approach 2:
The system uses feedback from image recognition and feature extraction to automatically determine authentication status. The terminal device compares captured image features with stored information and automatically confirms or rejects connection requests, providing secure authentication without repeated manual intervention
3Reliability
If manual authentication is required for connection, then authentication security is improved, but device complexity increases due to multiple operational steps
Solution Approach 1:
The patent extracts essential authentication information from the display image through feature extraction. By isolating and processing only the critical feature information (such as display content, patterns, or unique visual identifiers), the system simplifies the authentication process while maintaining security, reducing the complexity of manual operations required

AI summary
An electronic apparatus is provided. The electronic apparatus according to an exemplary embodiment includes a communicator, a storage, a display, and a processor configured to: based on a connection request signal being received from a user terminal device through the communicator, control to store in the storage a first image output through the display, based on a second image being received from the user terminal device through the communicator, identify a first object included in the stored first image that is same as second object included in the received second image, and based on a determination that a first feature of the first object is same as a second feature of the second object, control the communicator to transmit authentication information corresponding to the connection request signal to the user terminal device.
