Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 360-degree holographic projection technologies are used, then 3D display capability is improved, but device complexity increases making mass production difficult
Solution Approach 1:
The system divides the 3D display function into separate modules: a 3D projecting device for projection and an image capturing device for viewing angle detection. This segmentation allows each module to be independently optimized and manufactured, reducing overall system complexity while maintaining 360-degree display capability.
Solution Approach 2:
The patent uses existing 3D projecting devices and image capturing devices as standard components, making the system compatible with various existing technologies. This universality reduces complexity by avoiding custom development and enables mass production through standardized manufacturing processes.
2Device complexity
If fixed projection directions are used, then device complexity is reduced, but viewing adaptability deteriorates
Solution Approach 1:
The system dynamically adjusts the projection direction based on real-time detection of viewer position and elevation angle. The controller modifies the projection parameters adaptively, allowing the same simple projecting device to serve multiple viewing angles without adding mechanical complexity.
Solution Approach 2:
The patent changes projection parameters such as elevation angle and projection direction based on detected viewer characteristics. By adjusting these parameters dynamically, the system achieves flexible viewing adaptability while keeping the physical device structure simple and straightforward.
3Ease of manufacture
If standard 3D projecting devices are used, then manufacturing cost is reduced, but viewing angle coverage deteriorates
Solution Approach 1:
The image capturing device acts as an intermediary between the standard 3D projecting device and the viewer. It detects viewer position and elevation angle, then the controller adjusts projection parameters accordingly. This intermediary system enables standard devices to achieve wide viewing angle coverage without requiring expensive custom hardware.
Solution Approach 2:
Instead of using complex mechanical systems to physically adjust projection angles, the patent substitutes a software-based parameter adjustment system. The controller modifies projection parameters based on image capturing device feedback, achieving viewing angle adaptability through computational methods rather than mechanical complexity.
4Device complexity
If fixed elevation angle is used, then device complexity is reduced, but viewing comfort deteriorates
Solution Approach 1:
The image capturing device provides feedback on viewer elevation angle and position to the controller. The controller then adjusts projection parameters accordingly, creating a closed-loop system that automatically optimizes viewing comfort for different viewers without adding significant complexity to the device structure.
