Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional 3D display techniques are used to replicate holographic imagery, then the display can achieve three-dimensional effect, but the system becomes complex and computationally intensive
Solution Approach 1:
The patent segments the 3D object representation into primitives (points, lines, triangles, polygons) and processes them individually through the optical system. This segmentation allows the complex holographic rendering to be broken down into manageable computational units, reducing overall system complexity while maintaining image quality
Solution Approach 2:
The patent replaces complex mechanical optical systems with computational methods for generating and modulating light fields. By using computational algorithms to calculate light propagation and interference patterns, the system achieves holographic effects without requiring complex physical optical components
2Manufacturing precision
If high-quality 3D object representation is achieved through detailed primitive data processing, then image quality improves, but computation time increases
Solution Approach 1:
The patent performs preliminary classification of primitives into categories (points, lines, triangles, polygons) and pre-calculates their respective light field contributions. This preliminary organization allows for optimized processing paths for each primitive type, reducing overall computation time while maintaining high representation accuracy
Solution Approach 2:
The patent changes the parameter representation by using vertex identifiers and primitive identifiers as index keys in data structures. This parameter transformation enables efficient memory access and retrieval of primitive data, significantly reducing computation time for high-quality 3D rendering
3Productivity
If vertex data and primitive data are stored with detailed associations, then data retrieval efficiency improves, but memory usage increases
Solution Approach 1:
The patent creates indexed copies of vertex and primitive data using identifier systems. Instead of storing all detailed geometric information repeatedly, the system stores compact identifier references that point to the actual data, reducing memory usage while enabling efficient retrieval through the identifier index

AI summary
Methods, apparatus, devices, subsystems, and systems for holographically displaying three-dimensional objects are provided. In one aspect, a system includes a display and a controller coupled to the display. The controller is configured to: obtain primitive data of a plurality of primitives corresponding to an object, the primitive data indicating an overlap between adjacent primitives of the plurality of primitives; generate control signals for a plurality of display elements of a display using the primitive data of the plurality of primitives; and transmit the control signals to the display to modulate the plurality of display elements of the display based on the control signals.
