Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional 3D display technologies are used, then 3D imaging capability is achieved, but wearable devices and tracking mechanisms are required
Solution Approach 1:
The patent extracts and removes the requirement for wearable devices and tracking mechanisms from the 3D display system. By using electromagnetic field computations to directly generate 3D images from primitives, the system eliminates the need for these auxiliary components, allowing viewers to observe 3D images without any encumbrances.
2Productivity
If conventional 3D rendering methods are used, then 3D content can be displayed, but computational demands and processing time are high
Solution Approach 1:
The patent segments 3D objects into primitive components (points, lines, polygons) and computes electromagnetic field contributions from each primitive independently. This segmentation approach reduces computational complexity by breaking down complex rendering tasks into simpler, more efficient calculations that can be processed in real-time with lower energy consumption.
Solution Approach 2:
The patent changes the computational parameters from traditional ray-tracing or rasterization methods to electromagnetic field computation based on primitives. This parameter change enables more efficient calculations by directly computing the electromagnetic field contributions from geometric primitives, reducing both computational demands and processing time while achieving real-time rendering.
3Adaptability or versatility
If single-viewer 3D displays are used, then 3D image quality is maintained, but multiple viewers cannot view simultaneously
Solution Approach 1:
The patent creates a universal 3D display system that can serve multiple viewers simultaneously without requiring individualized tracking or adjustment for each viewer. The electromagnetic field computation method generates authentic 3D images that maintain their spatial properties and accuracy regardless of the number of viewers, making the system adaptable to both single and multi-viewer scenarios.
4Ease of manufacture
If specialized tools and software are used for 3D content creation, then holographic quality is achieved, but ease of content development is reduced
Solution Approach 1:
The patent enables copying conventional 3D content into the electromagnetic field computation framework. By accepting standard 3D primitives and geometry data from conventional content creation tools, the system allows developers to reuse existing 3D assets and workflows without requiring specialized holographic authoring tools, thereby maintaining both ease of content creation and holographic quality.

AI summary
Methods, apparatus, devices, and systems for three-dimensional (3D) displaying objects are provided. In one aspect, a method includes obtaining data including respective primitive data for primitives corresponding to an object, determining an electromagnetic (EM) field contribution to each element of a display for each of the primitives by calculating an EM field propagation from the primitive to the element, generating a sum of the EM field contributions from the primitives for each of the elements, transmitting to each of the elements a respective control signal for modulating at least one property of the element based on the sum of the EM field contributions, and transmitting a timing control signal to an illuminator to activate the illuminator to illuminate light on the display, such that the light is caused by the modulated elements of the display to form a volumetric light field corresponding to the object.
