Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display screen is in fixed state or can only be maintained at a fixed curvature, then the device structure is simple, but it is unable to meet consumer's demand for viewing comfort and complex shapes
Solution Approach 1:
The patent applies the dynamics principle by introducing a photoinduced deformation layer that can dynamically change the curvature of the flexible display screen in response to light stimulation. This layer enables the display to transition from a fixed state to multiple variable curvature states, allowing the screen to adapt to different viewing angles and user requirements without requiring complex mechanical adjustment mechanisms.
Solution Approach 2:
The patent replaces traditional mechanical curvature adjustment mechanisms with a photoinduced deformation layer that responds to light stimuli. Instead of using motors, gears, or other mechanical components to change the screen curvature, the invention uses the photo-responsive properties of the deformation layer to achieve curvature control, thereby simplifying the overall device structure while maintaining adaptability.
2Ease of operation
If the flexible display screen requires manual bending, then the device structure is simple, but it causes poor experience for users
Solution Approach 1:
The patent applies the self-service principle by enabling the flexible display screen to automatically adjust its curvature in response to user needs. The photoinduced deformation layer self-actuates when exposed to light, eliminating the need for manual bending operations. This automatic response mechanism improves ease of operation while maintaining relatively simple device structure.
Solution Approach 2:
The patent incorporates a detector configured to detect a viewing position of a viewer, and a controller that controls the control element to emit light according to the viewing position. This feedback mechanism allows the system to sense user viewing conditions and automatically adjust the screen curvature accordingly, significantly improving ease of operation and user experience without requiring complex manual control mechanisms.
3Adaptability or versatility
If a simple flexible display screen is used, then the device structure is simple, but it cannot fully meet the requirements of various consumer groups with complex and different shapes
Solution Approach 1:
The patent applies the segmentation principle by dividing the control element into multiple control sub-elements that can independently control different regions of the deformation layer. This segmentation allows for precise control of local curvature in different areas of the flexible display screen, enabling the creation of complex shapes and patterns that can meet diverse consumer requirements while maintaining a relatively simple overall system architecture.
