Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to control display states in existing foldable screens, then device complexity is reduced, but ease of operation deteriorates due to inconvenient user interaction
Solution Approach 1:
The foldable electronic apparatus automatically detects folding angles through encoding units and switches display states without manual input. The system serves itself by using sensors to monitor its own configuration and autonomously adjusting display parameters, eliminating the need for user intervention while maintaining operational simplicity
Solution Approach 2:
The encoding units continuously detect the folding angle and provide feedback to the control system. Based on this feedback, the system automatically switches between different display states (full screen, split screen, continuous image), creating a closed-loop control system that adapts to user needs without requiring manual operation
2Adaptability or versatility
If automatic angle detection and display switching is implemented, then ease of operation is improved, but device complexity increases due to additional sensors and control mechanisms
Solution Approach 1:
The encoding units serve multiple functions: they detect folding angles, determine display configuration state, and trigger appropriate display mode switches. This multi-functionality reduces the need for separate components for each function, thereby increasing adaptability while minimizing the increase in device complexity
Solution Approach 2:
The display control system is merged with the folding structure detection system. The encoding units are integrated into the folding modules, and the control unit combines angle detection, state determination, and display switching functions into a unified system, reducing overall complexity while enhancing adaptability
3Ease of operation
If multiple display states are available based on folding angles, then adaptability is improved, but device complexity increases due to additional control logic
Solution Approach 1:
The display configuration dynamically adapts to the folding angle detected by the encoding units. The system transitions between different display states (full screen, split screen, continuous image) based on real-time angle measurements, creating a dynamic rather than static display system that automatically adjusts to user needs
Solution Approach 2:
The system changes display parameters (display area allocation, image continuity, orientation) based on the folding angle parameter detected by the encoding units. By linking display state to a measurable physical parameter (angle), the system achieves automatic adaptation with relatively simple control logic

AI summary
A foldable electronic apparatus is provided and comprises a base unit and a display unit. The display unit includes: a main panel body having a first side and a bottom side perpendicular to each other, in which the bottom side is connected to the base unit; a first folding module provided on the first side and having at least one first encoding unit; a first side panel body provided on the first folding module; and a flexible screen including a main display area and a first side display area. The first encoding unit is used to detect a first angle between the main panel body and the first side panel body, and display states of the main display area and the first side display area are switched by the foldable electronic apparatus according to the first angle.
