Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional air floating display technology is used, then the display can be shown, but the brightness and image quality are insufficient
Solution Approach 1:
The patent segments the display system into distinct functional modules: a video display unit, a polarizing mirror unit, and a retroreflection plate unit. Each module performs a specific function in the light path, allowing independent optimization of brightness and image quality while resolving the contradiction between sufficient illumination and reliable image formation.
Solution Approach 2:
The patent introduces a polarizing mirror as an intermediary component between the video display and the retroreflection plate. This intermediary selectively reflects polarized light to enhance brightness while the retroreflection plate ensures high-quality image return, thereby resolving the contradiction between illumination intensity and image quality.
2Illumination intensity
If the display system uses fixed angle configuration, then the structure is simple, but the display quality and brightness are insufficient
Solution Approach 1:
The patent implements variable mechanisms that allow dynamic adjustment of the relative angles between the video display, polarizing mirror, and retroreflection plate. This dynamic configurability enables optimization of brightness and display quality for different viewing conditions while maintaining a relatively simple base structure, thus resolving the contradiction between performance and structural complexity.
3Use of energy by moving object
If conventional display technology is used, then power consumption is high, but the display quality is compromised
Solution Approach 1:
The patent replaces conventional direct illumination mechanisms with an optical system based on polarized light reflection and retroreflection. This substitution enables more efficient light utilization, reducing the power required for the video display while maintaining or improving display quality through the polarizing mirror and retroreflection plate configuration.
