Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the substrate is folded to vary its size, then the portability and flexibility are improved, but the image aspect ratio and quality deteriorate
Solution Approach 1:
The display apparatus dynamically adjusts the image resolution and display area based on the real-time folding state of the substrate. The control unit receives deformation information from the sensing unit and modifies display parameters accordingly, making the system adaptable to different folded configurations while maintaining proper aspect ratio.
Solution Approach 2:
The system changes the display resolution parameter according to the substrate's folding degree. When the substrate is folded, the resolution adjusting unit modifies the image resolution to match the new display area size, ensuring the aspect ratio remains correct despite the physical deformation.
2Adaptability or versatility
If the substrate is folded to vary its size, then the portability is improved, but the image quality deteriorates
Solution Approach 1:
The deformation sensing unit continuously monitors the substrate's folding state and provides feedback to the control unit. This feedback loop enables the system to detect changes in substrate configuration and automatically adjust display parameters to maintain optimal image quality throughout the folding process.
Solution Approach 2:
The display system dynamically adapts its resolution and display area based on the real-time folding state. By continuously adjusting these parameters in response to substrate deformation, the system maintains high image quality across various folded configurations rather than using a fixed display setup.
3Manufacturing precision
If the image resolution is adjusted according to substrate deformation, then the image quality is maintained, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it receives deformation information from the sensing unit, determines the folding state, calculates the appropriate resolution adjustment, and controls the resolution adjusting unit. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing device complexity while maintaining image quality.
