Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the auxiliary screen's display direction is fixed or requires manual adjustment, then the screen structure is simple, but the user experience deteriorates due to poor view angle and frequent manual adjustments
Solution Approach 1:
The auxiliary screen automatically adjusts its display direction based on the main screen's orientation and pre-set rules, eliminating the need for manual user adjustment. The system serves itself by autonomously determining and executing the optimal display direction for the auxiliary screen based on detected main screen angle, thereby improving ease of operation without requiring complex user interaction mechanisms.
Solution Approach 2:
The system pre-establishes correspondence relationships between main screen rotation angles and auxiliary screen display directions before actual use. When the main screen rotates to a specific angle, the auxiliary screen automatically adjusts to the pre-determined optimal direction, eliminating the need for real-time manual adjustment and improving operational convenience.
2Shape
If the auxiliary screen is positioned to avoid covering the main screen, then the main screen visibility is improved, but the auxiliary screen's view angle becomes poor
Solution Approach 1:
The auxiliary screen's display direction is made dynamic rather than fixed. It automatically adjusts based on the main screen's rotation angle, transitioning from a static positioning problem to a dynamic adaptation solution. This allows the auxiliary screen to maintain optimal view angles while avoiding coverage of the main screen through real-time angular adjustment.
Solution Approach 2:
The system changes the display direction parameter of the auxiliary screen based on the main screen's rotation angle parameter. By establishing a functional relationship between these two parameters, the system optimizes the auxiliary screen's viewing geometry dynamically, improving view angle without requiring manual intervention.
3Ease of operation
If the auxiliary screen requires manual adjustment of display direction, then the device structure remains simple, but the user must repeatedly adjust the screen direction causing inconvenience
Solution Approach 1:
The system automatically determines and adjusts the auxiliary screen's display direction based on the main screen's orientation, eliminating the need for user intervention. This self-service mechanism prevents time loss from repeated manual adjustments and improves operational efficiency by handling the adjustment process autonomously.
Solution Approach 2:
The system detects the main screen's rotation angle and uses this feedback information to automatically adjust the auxiliary screen's display direction. This closed-loop feedback mechanism ensures the auxiliary screen is always in the optimal position without requiring user input, thereby reducing time loss from manual adjustment.

AI summary
An electronic apparatus and its screen control method adapted to an electronic apparatus are provided. The electronic apparatus includes a first display screen, a second display screen, and a body. The first display screen is pivotally connected to the body along a first rotation axis, and the second display screen is disposed on an upper surface of the body. The method includes following steps. A sight of a user is detected by a sight sensor. In response to the sight projected on the second display screen at a default position, a screen rotation degree is determined according to a direction of the sight. According to the screen rotation degree, the second display screen is controlled to rotate from the default position along the second rotation axis to a display position, so that a view angle at which the user watches the second display screen satisfies a predetermined condition.
