Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flat display panel is curved at a certain curvature to decrease viewing distance deviation and maximize immersion, then the immersion of a user watching an image is maximized, but the curvature of the display panel cannot vary based on user preference
Solution Approach 1:
The display panel transitions from a static curved state to a dynamic adjustable state, allowing curvature to be changed based on user preference. The curvature variation device enables the display panel to switch between flat and curved states, making the system adaptive rather than fixed.
Solution Approach 2:
The display apparatus integrates multiple functions into a single system: it can operate in both flat and curved modes, and can adjust curvature to different degrees. This multi-functionality allows the same device to serve different viewing preferences and scenarios without requiring separate devices.
2Object-affected harmful factors
If sound is output in forward or downward direction with respect to display panel, then sound can be delivered to users, but sound quality is degraded due to interference between sounds reflected by walls or the ground
Solution Approach 1:
The sound output direction is changed from horizontal (forward) or downward to upward direction. By utilizing the vertical dimension, the sound waves are directed toward the ceiling and reflected back to users, avoiding ground reflections and wall interference that occur with forward or downward output directions.
Solution Approach 2:
Instead of directly outputting sound forward where it encounters wall reflections, the system outputs sound upward to utilize ceiling reflections as a beneficial element. The ceiling acts as a reflective surface that returns sound to users without the harmful interference caused by wall or ground reflections.
3Adaptability or versatility
If a curved display panel is used to maximize immersion, then viewing immersion is improved, but acoustic immersion is reduced due to degraded sound quality
Solution Approach 1:
The system dynamically adjusts both display curvature and sound output direction based on operational mode. In movie mode, the display curves and sound outputs upward for immersive experience. In other modes, the display can be flat and sound output direction can be adjusted, allowing optimization of both visual and acoustic immersion for different scenarios.
Solution Approach 2:
The system incorporates a curvature variation device that can adjust the display panel curvature based on detected or selected conditions. This feedback mechanism allows the system to optimize both visual curvature and acoustic direction to maximize overall user immersion rather than compromising one for the other.
