Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current three-dimensional display technologies are limited by their inability to provide interactive and high-resolution, full-color images that can be viewed from multiple angles without the need for special equipment or moving parts, and they often restrict user interaction, making them unsuitable for mobile devices and single-user applications.
Innovation Solution
A system comprising multiple projectors with adjustable throw and pivotable mounting, combined with a haze machine creating a cloud of suspended particles, allows for the creation of high-resolution, multi-colored three-dimensional images that can be viewed from various angles and interacted with, using cameras and image-processing software to detect and respond to physical intrusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single laser focuses on a point in air to create a plasma ball, then the display does not require moving parts in the display volume, but the display resolution is low due to relatively large pixels
Solution Approach 1:
The invention divides the display into multiple projection units, each projecting a portion of the overall image. By segmenting the image into multiple smaller components that can be projected with higher precision, the system achieves high resolution without requiring moving parts in the display volume. Each projection unit creates a focused image component that combines with others to form the complete high-resolution 3D image.
Solution Approach 2:
The invention combines multiple projected image components to form a complete high-resolution image. By merging several lower-resolution projections into a single composite image, the system achieves high overall resolution while maintaining the advantage of having no moving parts in the display volume. The multiple projection units work together synergistically to overcome the resolution limitation of individual plasma balls.
2Manufacturing precision
If swept-volume displays rapidly project slices onto a moving surface, then a three-dimensional image is presented, but the image cannot be touched without causing injury due to rapidly moving mechanical parts
Solution Approach 1:
The invention replaces the mechanical moving surface with a stationary display volume created by multiple projectors. Instead of using a physically moving surface that could injure users, the system uses optical projection to create a 3D image in air. This substitution eliminates harmful mechanical moving parts while maintaining the ability to present three-dimensional images, allowing safe user interaction.
Solution Approach 2:
The invention introduces a haze machine as an intermediary medium that enables optical projection without requiring a moving mechanical surface. The haze particles serve as a medium for light scattering and image formation, replacing the need for a physically moving surface. This intermediary approach allows the creation of a safe, touchable 3D image volume without the harmful effects of rapidly moving mechanical parts.
3Device complexity
If stereoscopic systems present the same images to both eyes, then the system is simple, but the viewer cannot see around the sides or back of the image and is limited to a single perspective view
Solution Approach 1:
The invention transitions from 2D stereoscopic imaging to true 3D volumetric imaging by adding spatial depth as a third dimension. Instead of presenting flat images with simulated depth, the system projects actual three-dimensional image components into space, allowing viewers to see around objects and change perspectives. This dimensional enhancement provides multiple viewing angles and perspectives while maintaining manageable system complexity through the use of multiple stationary projectors.
4Reliability
If static-volume devices use large pixels to create images in air, then no moving parts are required, but the display resolution is low and the display is limited to a single color or small number of colors
Solution Approach 1:
The invention segments the image into multiple color channels and resolution components that can be projected separately by multiple projectors. Each projector handles a portion of the overall image with high precision, and the combination of these segmented projections achieves high resolution and full color capability without requiring moving parts. The segmentation allows each projection unit to operate at its full capability while contributing to the overall high-quality composite image.
Solution Approach 2:
The invention uses composite light fields from multiple projectors to create a high-resolution, full-color 3D image. By combining the optical outputs of multiple projectors, each contributing different color and resolution information, the system creates a composite image that exceeds the capabilities of any single projector. This composite approach achieves high resolution and full color while maintaining the advantage of having no moving parts in the display volume.
