Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual switching between front screen and rear screen is implemented, then users can view themselves behind the camera, but the device cannot adapt to different application environments automatically
Solution Approach 1:
The system performs screen switching automatically based on sensor inputs without requiring user intervention. The central processing unit monitors sensor data (acceleration, light intensity, distance) and autonomously determines when to switch between front and rear screens, allowing the device to serve itself in adapting to different application environments.
Solution Approach 2:
The system continuously monitors sensor feedback (acceleration sensor detecting flip angle, light sensor detecting ambient light, distance sensor detecting object distance) and uses this feedback to automatically adjust screen switching decisions. This closed-loop feedback mechanism enables the device to adapt to changing environments dynamically.
2Adaptability or versatility
If multiple sensors are added to detect application environment, then intelligent switching capability is improved, but device complexity increases
Solution Approach 1:
Existing sensors in the device (acceleration sensor, light sensor, distance sensor) are repurposed to serve dual functions: their original purposes plus screen switching detection. This multi-functionality approach enables intelligent switching without adding dedicated sensors, thereby reducing overall device complexity while maintaining capability.
Solution Approach 2:
The screen switching control function is merged with the existing sensor system and central processing unit. Rather than creating a separate control system, the patent integrates screen switching logic into the existing sensor data processing pipeline, combining multiple functions into unified system operations.
