Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If volumetric three-dimensional display is used to achieve real dynamic three-dimensional stereoscopic display effect, then the three-dimensional display effect is improved, but the cost increases and the device life shortens
Solution Approach 1:
The patent replaces complex mechanical scanning systems with a static light field display structure. Instead of using mechanical means to create three-dimensional images, the invention uses precisely arranged light guides and light sources to directly form light fields that create three-dimensional visual effects without moving parts, thereby improving reliability and reducing cost
Solution Approach 2:
The patent creates multiple virtual images through light guides that redirect light from single or multiple light sources. These virtual images are positioned at different spatial locations to form three-dimensional scenes, effectively copying the light path to create multiple perceived image sources without requiring multiple physical light sources or complex mechanical systems
2Adaptability or versatility
If scanning volumetric three-dimensional technology is used to realize third-dimensional imaging, then the three-dimensional imaging capability is improved, but the mechanical complexity and physical volume increase
Solution Approach 1:
The patent eliminates mechanical scanning components by using a static light field generation system. Light guides with specific geometric arrangements and refractive indices are used to redirect light from sources to form three-dimensional images in space, replacing complex mechanical motion systems with optical path design
Solution Approach 2:
The patent transitions from two-dimensional display surfaces to three-dimensional light field generation by adding the spatial dimension through light guide arrangements. Multiple light sources are positioned at different depths and angles, and light guides redirect these lights to create images at various three-dimensional coordinates without mechanical movement
3Adaptability or versatility
If scanning volumetric three-dimensional technology is used to realize third-dimensional imaging, then the three-dimensional imaging capability is improved, but the physical volume occupied increases
Solution Approach 1:
The patent embeds light guides within the display device structure, nesting the optical paths inside the device housing. Light sources are positioned within the device, and light guides channel the light through the device body to project three-dimensional images externally, minimizing the space required while maintaining three-dimensional imaging capability
Solution Approach 2:
The patent uses vertical stacking of light sources and light guides in the depth dimension rather than spreading components horizontally. Multiple light sources are arranged at different heights and depths within a compact volume, and light guides route the light to create three-dimensional images, reducing the device's physical footprint

AI summary
The application provides a display device and a display method of the display device. A plurality of display components and a plurality of optical components are installed on a rotating mechanism, wherein each of the optical components is located on a corresponding one of the display components, and each of the optical components is disposed obliquely with respect to the corresponding one of the display components. So that when the driving mechanism drives the rotating mechanism to move, the light emitted by the plurality of display components is projected into an imaging space outside the rotating mechanism through the corresponding optical components to form a stereoscopic image.
