Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spatial display technologies, such as autostereoscopic and volumetric displays, face limitations in providing true three-dimensional imaging without user-worn apparatus, including reduced resolution, eyestrain due to convergence and accommodation conflicts, and lack of deep spatial visual qualities.
Innovation Solution
A 3D imaging system that generates three-dimensional spatial images by exploiting chromatic aberrations in optical components, focusing light of varying wavelengths at different points in space to create depth perception, using color-encoded 2D content displayed through Fresnel lenses in aerial or infinity viewing configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If autostereoscopic displays use parallax barrier or lenticular methods to provide multiple viewing zones, then spatial image capability is improved, but display resolution is reduced because each eye sees only half the horizontal screen resolution
Solution Approach 1:
The patent transitions from 2D display screens to 3D spatial projection, creating floating images in three-dimensional space. This dimensional change allows the system to provide spatial image capability without dividing the horizontal resolution, as the image is projected into depth space rather than being confined to a flat screen where multiple viewing zones would split the resolution.
2Manufacturing precision
If autostereoscopic displays create narrow viewing zones to prevent image distortion, then spatial image quality is improved, but ease of operation deteriorates because the observer must remain within viewing zones
Solution Approach 1:
The patent replaces the mechanical constraint of narrow physical viewing zones with an optical field approach. Multiple virtual viewing zones are created through optical projection and color encoding, allowing viewers to move freely while the system optically directs appropriate color-coded light paths to maintain image quality across extended spatial regions.
3Adaptability or versatility
If projection devices use reflective real-image displays or transmissive real-image displays to create floating images, then spatial perception is improved, but true three-dimensionality is lost because the imagery is planar
Solution Approach 1:
The patent applies local quality by color-encoding different depth portions of the image with specific colors (e.g., red for foreground, blue for background). This local color differentiation allows the system to create true three-dimensional spatial perception, as each color-coded region is focused at a different depth plane, giving the brain depth cues that planar displays cannot provide.
4Adaptability or versatility
If two full sets of optics and displays are used to combine floating planar images, then spatial impression is improved, but device complexity increases and the images appear to float within the housing rather than extending beyond it
Solution Approach 1:
The patent uses a single optical projection system that performs multiple functions: it projects the image, creates depth through chromatic aberration exploitation, and extends the image beyond the housing boundaries. This multi-functional approach eliminates the need for separate optical systems for different depth planes, reducing complexity while maintaining spatial impression.
5Adaptability or versatility
If volumetric or holographic displays are used to provide true 3D spatial qualities, then spatial perception is improved, but convergence and accommodation conflicts cause eyestrain when focusing on single plane
Solution Approach 1:
The patent changes the optical parameters by exploiting chromatic aberration to focus different colors at different depths. This creates a continuous depth field where the viewer's accommodation can naturally adjust to different focal planes without the convergence-accommodation conflict that plagues stereoscopic displays, as each color provides a different accommodation cue that matches the perceived depth.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables natural spatial viewing experiences by reducing conflicts between accommodation and convergence, providing enhanced spatial perception with pseudo-motion parallax and environmental cues, and improving the perceived depth and realism of imagery without actual voxels at precise points in space.
Implementation Method 1
A 3D imaging system includes an optical component that generates a three-dimensional (3D) spatial image from a two-dimensional (2D) content based on chromatic aberrations
Implementation Method 2
focusing light of varying wavelengths at different points in space to create depth perception
Implementation Method 3
Some methods create transmissive floating planar imagery from an electronic display placed behind a first Fresnel lens located behind a second Fresnel lens, which focus the light from the image source in front of the second Fresnel lens
Data Source
AI summary
The disclosure is directed to a 3D imaging system that generates a three-dimensional (3D) spatial image of a source content, e.g., images or videos. The source content is a two-dimensional (2D) color-encoded content in which different portions of the source content are encoded with different colors based on a depth at which the corresponding portion is to be formed relative to the other portions in the 3D spatial image. The 3D imaging system includes an optical component, e.g., a Fresnel lens, to generate the 3D spatial image. In the aerial viewing configuration of the 3D imaging system, the 3D imaging system generates the 3D spatial image in a space between the optical component and a viewer. In the infinity viewing configuration of the 3D imaging system, the 3D imaging system generates the 3D spatial image in a space between the optical component and optical infinity.
