Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional volumetric 3D display systems use high-speed projectors to project images onto optical plates, then 3D images can be displayed, but the system generates noise and vibration and requires high cost
Solution Approach 1:
The patent replaces the mechanical projection system with a display panel system that emits light directly. Instead of using a projector to shine light onto optical plates, the invention uses display panels that can be directly configured to show 3D images, eliminating the mechanical projection components that generate noise and vibration.
Solution Approach 2:
The patent extracts and removes the projector component from the system. By taking out the high-speed projector that causes noise and vibration, the invention retains only the essential display function through optical plates or display panels, thereby eliminating the harmful noise and vibration while maintaining 3D display capability.
2Productivity
If conventional volumetric 3D display systems use high-speed projectors, then images can be projected at required speeds, but the system becomes costly and complex
Solution Approach 1:
The patent replaces the complex mechanical projection system with a simpler display panel-based system. The high-speed projector and associated mechanical components are replaced by display panels that can be directly controlled to show images, significantly reducing system complexity while maintaining the ability to display images at required speeds.
Solution Approach 2:
The patent extracts and removes the complex projector subsystem, retaining only the essential image display function through optical plates or display panels. This extraction simplifies the overall system architecture by eliminating unnecessary mechanical components while preserving the core functionality of displaying images at high speed.
3Reliability
If conventional volumetric 3D display systems use fixed viewing zones, then 3D images can be displayed, but the viewing angle is restricted
Solution Approach 1:
The patent introduces dynamic control of the display panels to adapt the viewing characteristics. By dynamically controlling the optical plates or display panels, the system can adjust the viewing angle and image display characteristics in real-time, transforming the fixed viewing zone limitation into a dynamic, adaptable system that can serve multiple viewing positions.
Solution Approach 2:
The patent creates a universal display system where the same optical plates or display panels can serve multiple functions by adjusting their configuration. The system can adapt to different viewing angles and positions, making it universally applicable to various viewing scenarios rather than being limited to a single fixed viewing zone.
4Reliability
If conventional volumetric 3D display systems use multi-plate optical panels, then 3D images can be formed, but the system size and cost increase
Solution Approach 1:
The patent merges the functions of multiple optical plates into a single integrated display panel system. Instead of using separate optical plates for different functions, the invention combines these functions into unified display panels that can perform multiple operations, thereby reducing the overall number of components and system size while maintaining 3D image formation capability.
Solution Approach 2:
The patent creates universal display panels that can perform multiple functions previously requiring separate optical plates. These multi-functional panels can handle different image processing tasks and optical functions within a single component, reducing system size and complexity while preserving the ability to form 3D images.
