Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face recognition function is used to provide user interface, then user authentication is improved, but user input variety is limited
Solution Approach 1:
The camera system is designed to serve multiple functions: it can capture facial images for authentication purposes and simultaneously capture additional figures or components for interface interaction. This multi-functionality allows the same hardware component to address both authentication reliability and input variety requirements without requiring separate dedicated systems for each function.
Solution Approach 2:
The image processing system segments the captured image into different regions of interest, identifying both the facial figure for authentication and additional figures or components for input recognition. By dividing the analysis task into separate recognition modules, the system can independently process authentication and input variety functions, resolving the contradiction between these two requirements.
2Device complexity
If only facial image analysis is performed, then processing simplicity is maintained, but interaction capability is limited
Solution Approach 1:
The system performs preliminary image capture and basic processing to identify both facial figures and additional figures or components. By preparing the image data and extracting relevant information in advance, the system enables complex interaction capabilities without requiring complex real-time processing, thus maintaining processing simplicity while enhancing interaction capability.
Solution Approach 2:
An intermediary processing layer is introduced that handles the complexity of analyzing additional figures and components. This intermediary module processes the captured images to extract information about additional elements, shielding the user interface from the underlying processing complexity while providing rich interaction capabilities.
3Adaptability or versatility
If additional component recognition is added to face recognition, then user input variety is improved, but system complexity increases
Solution Approach 1:
The system merges the face recognition module and additional figure recognition module into a unified processing architecture. Both recognition functions share common resources such as the camera, image processing unit, and recognition algorithms. By combining these functions into a single integrated system, the patent reduces overall system complexity compared to having separate independent systems, while still providing varied user input capabilities.

AI summary
A method and a mobile device having a face recognition function using an additional component. The method includes determining whether the face recognition function has been activated in a first state of the mobile device, acquiring an image if the face recognition function has been activated, extracting a facial figure or at least one main component included in the facial figure by analyzing the acquired image, determining whether a face recognized from the image matches a registered user's face based on the facial figure or the at least one main component, determining whether an additional figure recognition function has been activated, extracting an additional figure or at least one additional component included in the additional figure, if the additional figure recognition function has been activated, and switching the mobile device to a predetermined second state corresponding to the additional figure or the at least one additional component.
