Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multi-view 3D display devices use periodically arranged views to form viewing zones, then the device structure is simplified, but visual jumps occur and viewing continuity is poor
Solution Approach 1:
The patent applies dynamics by transitioning from a static periodic view arrangement to a dynamic eye-tracking-based view assignment system. The display device dynamically determines which views to present based on real-time eye position detection, allowing continuous adjustment of image slices without the rigid periodic structure that causes visual jumps. This resolves the contradiction by maintaining structural simplicity while achieving viewing continuity through dynamic adaptation to viewer position.
Solution Approach 2:
The patent implements feedback through the human eye tracker that continuously monitors eye positions and provides this information to the controller. The controller uses this feedback to adjust which image slices are displayed in each viewing zone, ensuring that the correct views are always presented to each eye. This feedback mechanism eliminates visual jumps by adapting the display content to the actual viewer position, thereby improving viewing continuity without complicating the overall device structure.
2Device complexity
If only 4 views are spatially continuously distributed, then the device complexity is reduced, but the number of views is limited and viewing experience is poor
Solution Approach 1:
The patent applies universality by making the display device capable of presenting multiple different view configurations depending on viewer position. Instead of being limited to a fixed 4-view arrangement, the system can dynamically select from numerous possible view combinations based on where the viewer's eyes are located. This multi-functionality allows the same physical device structure to deliver adaptability in the number of views presented, resolving the contradiction between structural simplicity and viewing versatility.
Solution Approach 2:
The patent utilizes parameter changes by varying which image slices are assigned to which viewing zones based on detected eye positions. The system changes the display parameters (which views are active in which zones) dynamically rather than maintaining a fixed configuration. This allows the device to effectively increase the number of available views without changing the physical structure, thereby achieving versatility while maintaining structural simplicity.
3Device complexity
If image slices are fixed in each viewing zone, then the control system is simple, but visual jumps occur when eyes move between zones
Solution Approach 1:
The patent applies preliminary action by having the eye tracker continuously monitor eye positions in advance and the controller pre-adjust the image slice assignments in viewing zones before visual jumps occur. By detecting eye movement trends and proactively updating which views are displayed in each zone, the system prevents visual jumps rather than reacting to them after they occur. This maintains relatively simple control logic while dramatically improving viewing experience through anticipatory adjustments.
Solution Approach 2:
The patent implements feedback through the eye tracking system that continuously provides eye position information to the controller. This real-time feedback enables the controller to adjust image slice assignments dynamically based on actual viewer position, eliminating visual jumps that would occur with fixed assignments. The feedback mechanism allows the control system to remain relatively simple while achieving smooth, continuous viewing experience by constantly adapting to viewer movement.
