Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a retroreflection plate is used to form an air floating video, then the video can be displayed in air, but the brightness and quality of the video are insufficient
Solution Approach 1:
The patent changes the virtual position parameter of the 3D model relative to the air floating video by setting it in a direction opposite to the traveling direction of the principal ray. This parameter adjustment optimizes the optical path and light distribution, thereby improving both the brightness and quality of the air floating video display.
2Adaptability or versatility
If 3D data rendering is performed with virtual position adjustment, then stereoscopic viewing and motion parallax are achieved, but the device complexity increases
Solution Approach 1:
The controller performs multiple functions by integrating the virtual position setting, 3D data rendering, and motion parallax processing into a single system. The same controller that manages the video display also handles the 3D model positioning and stereoscopic viewing calculations, reducing the need for separate dedicated components.
3Measurement precision
If the virtual position is set opposite to the principal ray direction, then image clarity and security are improved, but power consumption increases
Solution Approach 1:
By optimizing the virtual position parameter to be opposite to the principal ray direction, the system achieves improved image clarity and security features. This parameter change allows for better light distribution and reduced ghost images, though it requires additional processing power that is managed through efficient rendering techniques.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus provides a brighter, higher-quality air floating video display with improved image clarity and security features, reducing power consumption and minimizing ghost images.
Implementation Method 1
a retroreflection plate which a light flux from the video display enters; the light flux reflected by the retroreflection plate forms an air floating video as a real image in air
Implementation Method 2
