Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional digital TV services are used, then various services can be provided, but users have difficulty in selecting desired programs among numerous channels
Solution Approach 1:
The system automatically performs face recognition to identify the user and retrieves favorite channel information from stored user data without requiring manual channel selection. The control unit autonomously selects and displays favorite channels based on recognized user identity, eliminating the need for users to manually search through numerous channels.
Solution Approach 2:
User preference data including favorite channels and keywords are pre-stored in the storage unit during initial setup or previous interactions. When a user approaches the display device, the system retrieves pre-stored information about that user and automatically presents relevant favorite channels, avoiding the need for real-time manual selection.
2Extent of automation
If face recognition technology is implemented, then user identification is automated, but device complexity increases
Solution Approach 1:
The image acquisition unit serves multiple functions: capturing images for face recognition, displaying visual feedback to users, and potentially serving as the primary display interface. The control unit handles multiple tasks including face recognition, user data retrieval, channel selection, and display control, reducing the need for separate dedicated components.

AI summary
Provided is an operating method of an video display device. The method includes: receiving, by the video display device, user input for displaying a favorite channel; obtaining a user's face image of the video display device; determining whether the obtained user's face image is identical to one face image among at least one pre-stored user's face image; when the obtained user's face image is identical to the pre-stored user's face image, searching for a favorite channel matching a favorite keyword corresponding to the pre-stored user's face image; and displaying the found favorite channel.
