Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional air floating video display is used, then basic video display function is achieved, but brightness and image quality are insufficient
Solution Approach 1:
A retroreflection plate is introduced as an intermediary optical element between the video display and the air floating video formation. This retroreflection plate reflects light back through the display, effectively doubling the light path and increasing brightness while maintaining image quality through controlled optical interaction.
Solution Approach 2:
The virtual position of the 3D model is deliberately set at a position shifted relative to the air floating video real image in the direction opposite to the traveling direction of principal ray. This parameter change in virtual position creates motion parallax effect, enhancing the three-dimensionality and visual quality of the displayed video.
2Ease of operation
If virtual 3D model position is shifted to create motion parallax, then viewing enjoyment is improved, but device complexity increases
Solution Approach 1:
The controller pre-calculates and sets the virtual position of the 3D model relative to the air floating video real image before the video is displayed. This preliminary positioning action creates the motion parallax effect automatically during playback, enhancing viewing enjoyment without requiring complex real-time adjustments or additional user interaction mechanisms.
