Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed stereoscopic image display system is used, then the structure is simple, but the view angle and depth cannot be adjusted according to user position
Solution Approach 1:
The patent implements dynamic adjustment of view angle and depth parameters based on real-time detection of user position. The system transitions from a fixed stereoscopic display to a dynamic one that adapts to multiple users at different locations, using cameras or infrared sensors to track user positions and continuously adjusting rendering parameters accordingly.
Solution Approach 2:
The system changes rendering parameters (view angle, depth, binocular disparity) based on detected user position information. By dynamically modifying these parameters according to user location, the system achieves adaptability without requiring complete system redesign, thus managing complexity while improving versatility.
2Adaptability or versatility
If spatial division technique is used to separate left and right images, then binocular disparity is achieved, but the view is limited to fixed positions
Solution Approach 1:
The system combines spatial division with dynamic parameter adjustment, allowing users to move freely while the system continuously adapts the stereoscopic rendering to their positions. This dynamic approach maintains binocular disparity benefits while enabling multi-user flexibility.
Solution Approach 2:
The system serves multiple users simultaneously by detecting their positions and providing personalized stereoscopic views. The same display system adapts to different users' locations and viewing conditions, achieving multi-functionality without requiring separate fixed viewing positions for each user.
3Manufacturing precision
If time division technique is used to display left and right images, then resolution is maintained, but continuous stereoscopic view is interrupted
Solution Approach 1:
The patent merges time division technique with dynamic parameter adjustment, combining the resolution benefits of time division with the continuous viewing experience achieved through real-time position tracking and parameter modification. This hybrid approach maintains high resolution while reducing the perceptible interruptions.
4Adaptability or versatility
If polarization division technique is used, then left and right images are separated, but the system cannot adapt to user motion
Solution Approach 1:
The system combines polarization division with dynamic parameter adjustment based on user position detection. By integrating real-time position tracking with polarization-based image separation, the system achieves adaptability to user motion while maintaining the benefits of polarization division for clear left-right image separation.
