Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dynamic 3D objects are generated using traditional photogrammetry technology, then the objects can represent real-world things, but the computational costs and specialized knowledge requirements become enormous
Solution Approach 1:
The patent uses 2D images captured from multiple angles as simplified copies of the 3D object, avoiding the need to generate complex dynamic 3D models. The display control unit rotates and overlays these 2D images to create a pseudo-3D effect, significantly reducing computational requirements while maintaining visual accuracy.
Solution Approach 2:
The patent replaces traditional mechanical 3D modeling and rendering systems with a computational approach that uses 2D image manipulation. By substituting complex 3D geometry processing with 2D image rotation and overlay operations, the system achieves 3D visualization with much lower computational complexity.
2Ease of operation
If 2D images are displayed without rotation control, then the display is simple, but the virtual space representation lacks depth and viewpoint accuracy
Solution Approach 1:
The patent introduces dynamic rotation of 2D images based on viewpoint parameters. The display control unit rotates images around the vertical axis according to the observer's position, creating a dynamic visualization that adapts to different viewing angles while maintaining operational simplicity through automated control.
Solution Approach 2:
The patent adds a rotational dimension to 2D image display by rotating images around the vertical axis. This creates a pseudo-3D effect where 2D images are transformed through rotational movement to represent spatial relationships and depth, effectively adding dimensional information without requiring full 3D modeling.
3Adaptability or versatility
If static 3D objects are generated using photogrammetry, then the objects can be created from 2D images, but dynamic 3D objects cannot be effectively generated
Solution Approach 1:
The patent applies periodic rotation to 2D images to simulate dynamic 3D objects. By rotating images at regular intervals and overlaying them, the system creates the illusion of motion and dynamism, enabling the representation of moving objects without requiring complex dynamic 3D modeling capabilities.
Solution Approach 2:
The patent introduces time and rotation parameters as intermediaries between static 2D images and dynamic 3D representation. These parameters mediate the transformation by controlling how 2D images are rotated and overlaid over time, creating dynamic effects without requiring actual dynamic 3D models.
