Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional volumetric display technologies are used to present three-dimensional images, then realistic three-dimensional representation is achieved, but device complexity and computational requirements increase significantly
Solution Approach 1:
The three-dimensional image is segmented into multiple two-dimensional image slices that are projected onto different layers of the volumetric display. Each layer displays a portion of the complete 3D image, and the human visual system integrates these slices to perceive a realistic three-dimensional representation. This segmentation reduces the computational complexity of generating and processing volumetric data while maintaining visual fidelity.
2Reliability
If light is projected through multiple layers to create volumetric images, then three-dimensional depth perception is improved, but unwanted reflections and light penetration between adjacent layers occur
Solution Approach 1:
A separation arrangement is extracted and positioned between adjacent layers of the volumetric display. This separation arrangement selectively blocks unwanted reflections and prevents light penetration between adjacent layers while allowing the intended projected light to pass through. By removing this harmful element, the system achieves better layer isolation and improved three-dimensional depth perception without crosstalk between layers.
3Reliability
If multi-layer volumetric displays are used to present three-dimensional images, then physical depth cues are provided, but light scattering between layers reduces image clarity
Solution Approach 1:
The separation arrangement acts as an intermediary element positioned between adjacent light-diffusing layers. It mediates the interaction between layers by blocking stray light and reflections while permitting the intended projected light to pass through. This intermediary structure prevents light scattering between layers, thereby maintaining image clarity and contrast while preserving the physical depth cues provided by the multi-layer architecture.
