Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional holography is used to create three-dimensional images, then actual image depth is achieved, but ghost effects occur and the image is static
Solution Approach 1:
The patent applies dynamics by using a vibrating screen display that physically oscillates to generate three-dimensional images. The screen vibrates in the vertical direction at frequencies between 60-200 Hz, creating multiple image planes that sweep through a volume space. This dynamic mechanical vibration replaces static holographic methods, allowing the image to move and change depth continuously while eliminating ghost effects through precise temporal and spatial control of the vibrating elements.
2Loss of information
If computer software driven methods are used to produce three-dimensional images, then three-dimensional information is generated, but large amounts of computing power are required
Solution Approach 1:
The patent replaces complex computer software processing with a simple mechanical vibration system. Instead of using computational algorithms to generate three-dimensional effects, the invention uses a physically vibrating screen that creates volumetric images through mechanical motion. This substitution dramatically reduces computing power requirements while maintaining three-dimensional information integrity, as the mechanical vibration naturally encodes depth and spatial information without requiring heavy computational processing.
3Loss of information
If stereovision is used to create three-dimensional images, then binocular disparity is utilized, but only static parallax is achieved
Solution Approach 1:
The patent transforms static parallax into dynamic volumetric imaging through screen vibration. The vibrating screen creates multiple image planes that sweep through space over time, providing continuous depth information rather than fixed parallax. This dynamic approach maintains binocular disparity information while adding temporal and spatial dimensions, allowing viewers to perceive true three-dimensional depth as the image planes move through the viewing volume.
4Loss of information
If split image display is used to create three-dimensional images, then foreground and background images are projected, but detailed depth information is limited
Solution Approach 1:
The patent segments the display into multiple independently controllable vibrating elements arranged in a grid pattern on the screen. Each element can vibrate with different amplitude and phase, allowing precise control over the position and intensity of light emitted from each point. This segmentation enables the creation of detailed volumetric images with fine depth resolution, as each segment contributes to the three-dimensional structure through its specific vibration characteristics, providing superior depth information compared to split-image methods.
