Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a curved display panel is used to provide constant distance from user's eyes to center and opposite sides of the screen, then the three-dimensional effect and immersion are improved, but screen distortion is sensed by users located away from the center of curvature
Solution Approach 1:
The display panel is divided into multiple independently controllable regions or segments. By segmenting the panel, the system can adjust different portions of the display to compensate for viewing angle variations, ensuring consistent image quality and minimizing distortion for users at different positions, including off-center locations.
Solution Approach 2:
Different regions of the display panel are assigned different properties or characteristics. The system adjusts local display parameters (such as curvature, brightness, or geometric distortion) in specific areas to optimize the viewing experience for users at different positions, thereby reducing perceived distortion while maintaining immersion.
2Ease of operation
If a curved display panel is used to enhance immersion and reduce eye fatigue, then user comfort is improved, but the device occupies a lot of space
Solution Approach 1:
The display panel's curvature is made dynamically adjustable rather than fixed. The system can change the curvature radius and display shape in real-time based on viewing distance and user position. This allows the display to provide immersive curved viewing when needed while collapsing to a flatter configuration to reduce space occupation when not in use.
Solution Approach 2:
The physical parameters of the display panel, particularly the curvature radius and geometric shape, are made variable. By changing these parameters dynamically, the system can transition between a curved immersive mode for comfortable viewing and a compact flat mode for space-saving storage or transport.
3Adaptability or versatility
If the display panel is bent into various shapes to accommodate different viewing angles and spaces, then adaptability is improved, but damage to the display panel occurs
Solution Approach 1:
Protective cushioning layers or stress-distributing structures are integrated into the display panel assembly before bending occurs. These cushioning elements absorb and distribute mechanical stress during shape changes, preventing direct stress concentration on the display panel and thereby reducing the risk of damage while enabling flexible bending.
Solution Approach 2:
The display panel assembly uses composite materials with different mechanical properties. The structure combines rigid display panels with flexible support structures, stress-distributing layers, and protective cushioning materials. This composite construction enables the panel to be bent into various shapes while the protective layers absorb stress and prevent damage to the display elements.
