Engineering Contradiction Analysis
1Length of stationary object
If conventional 3D display technologies are used, then 3D images can be displayed, but the depth range is limited and images are attached to the display surface
Solution Approach 1:
The patent transitions from conventional 2D display surfaces to 3D volumetric display by introducing a virtual focus point in space. The optical component creates light convergence at a specific depth position, enabling images to be displayed in three-dimensional space rather than confined to a flat surface, thus expanding the depth range from zero to a measurable volumetric dimension.
Solution Approach 2:
The optical component serves as an intermediary element between the backlight source and the observer. It manipulates light paths to create a virtual focus point, acting as a mediator that transforms conventional backlight emission into focused 3D light convergence, enabling the formation of floating images at specific depth positions without requiring complex mechanical structures.
2Adaptability or versatility
If floating images are created, then human interaction and immersion are enhanced, but the technology requires advanced optical components
Solution Approach 1:
The optical component is designed to perform multiple functions: it converges light at the virtual focus point to create 3D images, controls the depth positioning of floating images, and enables wide viewing angles. This multi-functionality allows a single component to achieve enhanced human interaction capabilities without requiring multiple separate optical systems, thereby managing complexity while improving adaptability.
Solution Approach 2:
The patent utilizes parameter changes in light propagation by adjusting the optical component's properties to control where light converges in space. By modifying optical parameters such as focal length and refractive index, the system can dynamically adjust the virtual focus point position, enabling flexible depth control and enhanced user interaction without mechanical movement or complex reconfiguration.
