Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light projection technology is used for three-dimensional imaging, then the projection can be achieved on a two-dimensional plane, but the viewing angle is limited and multi-person multi-angle viewing cannot be achieved
Solution Approach 1:
The patent replaces the optical-mechanical light projection system with a particle suspension system controlled by force fields. Instead of projecting light onto a fixed 2D plane, the system suspends scattering particles in 3D space using acoustic or electromagnetic force fields, allowing the projection plane to be dynamically positioned and viewed from multiple angles simultaneously.
Solution Approach 2:
The patent transitions from two-dimensional plane projection to three-dimensional spatial particle suspension. By moving the projection plane from a fixed 2D surface to a dynamically adjustable 3D particle cloud, the system enables viewing from multiple angles and depths, achieving true multi-person multi-angle viewing capability.
2Adaptability or versatility
If multiple projectors are set up with specific positions and orientations to achieve three-dimensional projection, then the projection transform can be achieved, but the device complexity increases
Solution Approach 1:
The patent extracts the projection function from multiple physical projectors and consolidates it into a single projection source that targets a dynamically formed 3D particle plane. By removing the need for multiple synchronized projectors with precise calibration, the system significantly reduces device complexity while maintaining 3D projection capability.
Solution Approach 2:
The patent introduces scattering particles as an intermediary medium between the projection source and the viewer. These particles act as a dynamic projection plane that can be formed and repositioned using force fields, eliminating the need for complex multi-projector arrangements and rigid calibration systems.
3Adaptability or versatility
If holographic projection technology is used to reproduce three-dimensional images, then light can be projected to form stereoscopic images, but the viewing angle remains limited and multi-person viewing is not achieved
Solution Approach 1:
The patent introduces dynamic repositioning capability to the projection system. Instead of a fixed holographic plane, the scattering particles can be dynamically moved and reconfigured using controllable force fields, allowing the projection plane to adapt to different viewing positions and enable multiple people to view the stereoscopic image from various angles simultaneously.

AI summary
A three-dimensional imaging system and method are provided. The three-dimensional imaging system includes a suspension force field generator, a projection module, and a controller. The suspension force field generator generates a suspension force field to suspend a plurality of scattering particles used for scattering incident light and distribute the scattering particles on a projection plane. The projection module projects an image on the projection plane. The controller is coupled to the suspension force field generator and the projection module, controls the suspension force field generator to change the suspension force field so that the projection plane where the scattering particles are distributed moves in a display space, extracts a slice plane image that matches a position of the projection plane from multiple slice plane images sliced from a three-dimensional stereoscopic image, and controls the projection module to project the extracted slice plane image to the projection plane.
