Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If display direction is determined based on primary display screen data only, then device structure is simple, but display direction accuracy deteriorates in variable attitudes
Solution Approach 1:
The patent divides the sensing system into separate motion sensors for each display screen (first motion sensor for first display screen, second motion sensor for second display screen). Each sensor independently detects the attitude of its corresponding screen, enabling accurate display direction determination even when screens are folded at different angles. This segmentation resolves the contradiction by improving measurement precision through distributed sensing while maintaining reasonable device complexity.
Solution Approach 2:
The patent implements a universal display direction determination method that works across multiple folding states (unfolded, half-folded, fully folded). The system uses multiple motion sensors and a unified control logic to adaptively adjust display directions regardless of the folding configuration. This multi-functionality approach allows the same system to accurately handle various attitudes without requiring separate solutions for each state, resolving the accuracy issue while keeping the overall structure manageable.
2Measurement precision
If multiple motion sensors are added for each display screen, then display direction accuracy is improved, but device complexity increases
Solution Approach 1:
The patent employs dynamic adaptation where the display direction is continuously adjusted based on real-time folding angle data from multiple motion sensors. The system dynamically determines the appropriate display direction (portrait, landscape, reverse portrait) according to the current folding state. This dynamic approach allows accurate display orientation without requiring complex mechanical structures, as the system adapts software-controlled display directions based on sensor feedback.
Solution Approach 2:
The patent implements a feedback mechanism where motion sensors continuously monitor the folding angle and attitude of each display screen, and this information is fed back to the processor to dynamically adjust the display direction. The system uses the detected folding state as feedback to automatically select the appropriate display orientation, ensuring accuracy while maintaining simple control logic. This closed-loop feedback resolves the contradiction by using minimal additional sensors with intelligent processing.

AI summary
This application pertains to terminals and presents a display method and an electronic device, specifically a foldable electronic device. The device comprises a first display screen, a second display screen, a first motion sensor, and a second motion sensor. The display method involves: obtaining first data, second data, and folding angle information; determining a first direction from the first data, representing the interface direction of the first display screen; determining a second direction from the second data, representing the interface direction of the second display screen; and calculating a third direction based on the folding angle information, the first direction, and the second direction, which indicates the interface direction for both display screens. This method allows the foldable electronic device to self-adaptively adjust the display direction of its interface according to varying attitudes.
