Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display modes are statically configured, then device complexity is reduced, but adaptability to different postures and usage scenarios deteriorates
Solution Approach 1:
The display mode is made dynamic by continuously monitoring device posture through inertial sensors and automatically adjusting the display orientation and activation state based on detected posture changes, enabling the display to adapt to different usage scenarios without manual intervention
Solution Approach 2:
The system implements feedback control by using inertial sensors to detect device posture, processing this information through the processor, and automatically adjusting display modes based on the detected posture, creating a closed-loop system that continuously adapts to changing device orientations
2Measurement precision
If multiple inertial sensors are added to detect posture accurately, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The inertial sensing system is segmented into multiple independent sensors placed in different housing portions, with each sensor independently detecting local acceleration and orientation data, allowing the system to achieve comprehensive posture measurement through distributed sensing
Solution Approach 2:
Data from multiple inertial sensors are merged and processed by the processor to compute overall device posture, combining information from different sensor locations to achieve more accurate and reliable posture detection than a single sensor could provide
3Adaptability or versatility
If display mode changes frequently based on posture, then adaptability is improved, but loss of time for mode switching increases
Solution Approach 1:
The system performs preliminary detection of device posture using inertial sensors and proactively prepares appropriate display mode transitions before the user actually needs to use the device in a particular orientation, reducing perceived latency by anticipating usage patterns

AI summary
An electronic device includes: a first housing including a first surface and a second surface opposite to the first surface; a second housing including a third surface and a fourth surface opposite to the third surface; a first display on the first and third surfaces; a second display on the second surface; a first inertial sensor in the first housing; a second inertial sensor in the second housing; and a processor. The processor is configured to: identify, using the first and second inertial sensors, that an angle between a first direction in which the first surface faces and a second direction in which the third surface faces is within a designated range, identify that first data, which is related to a posture of the electronic device and is identified using the second inertial sensor, is within a first range, and change a display mode of the second display.
