Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tracking technology combined with 3D image arrangement technology is used to achieve autostereoscopic 3D, then 3D viewing functionality is enabled, but system complexity increases due to multiple modules requiring coordination
Solution Approach 1:
The patent combines the 3D image arrangement module, tracking module, and scheduling module into an integrated system controlled by a central processor. This merging reduces the complexity of coordinating multiple independent modules while maintaining the autostereoscopic 3D viewing functionality through unified control architecture.
Solution Approach 2:
The display device is designed with multi-functionality to support both 2D and 3D viewing modes, as well as different viewing angles. The light splitting device can be dynamically controlled to provide various display modes, making the system adaptable to different user needs without requiring separate dedicated systems for each function.
2Reliability
If light splitting device is continuously operated for 3D display, then 3D viewing quality is maintained, but power consumption increases
Solution Approach 1:
The light splitting device is operated periodically rather than continuously. The display device switches between 2D and 3D modes based on user interaction and tracking data, allowing the light splitting device to be activated only when 3D viewing is required. This periodic operation maintains 3D viewing quality when needed while significantly reducing overall power consumption.
3Ease of operation
If multiple modules (tracking, image arrangement, scheduling) are coordinated for smooth 3D display, then viewing experience is improved, but system reliability decreases due to more potential failure points
Solution Approach 1:
The system incorporates feedback mechanisms where the tracking module continuously monitors user position and the scheduling module adjusts the light splitting device operation based on this feedback. This closed-loop control ensures smooth 3D viewing experience while the system can detect and respond to operational issues, thereby maintaining reliability despite the complexity of multiple coordinated modules.
4Measurement precision
If 3D image arrangement data is calculated in real-time based on user position, then viewing accuracy is improved, but data processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-calculating 3D image arrangement data based on predicted user positions and preparing it in advance. The tracking module continuously monitors user movement, and the scheduling module pre-processes arrangement data so that when the user reaches a specific position, the 3D images are already arranged and ready for immediate display, maintaining viewing accuracy while reducing processing delays.
