Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single large high-resolution display is used, then display resolution is improved, but device weight and complexity increase
Solution Approach 1:
The display system is divided into multiple small display facets (e.g., 100x100 microlens array with individual facets) that are distributed across a large area. Each facet operates independently but collectively they form a high-resolution light field display, eliminating the need for a single large high-resolution panel that would be heavy and complex.
Solution Approach 2:
The patent transitions from a traditional 2D display plane to a 3D distributed array of facets arranged in a microlens structure. This dimensional change allows light field reconstruction in three-dimensional space, achieving high resolution through spatial distribution rather than increasing pixel density on a single surface.
2Productivity
If traditional electronic displays and cameras are used separately, then functional simplicity is maintained, but system integration and efficiency are reduced
Solution Approach 1:
The patent merges the display and camera functions into a single integrated light field system. The same microlens array and facet structure serves both for displaying light fields and for capturing images, eliminating the need for separate electronic display and camera components.
Solution Approach 2:
The distributed facet array structure performs multiple functions: it displays light fields for VR/AR/MR applications, captures images through its microlens array, and enables unidirectional emulated transparency. This multi-functionality reduces overall system complexity compared to using separate specialized components.
3Manufacturing precision
If high-density display arrays are implemented, then display density is improved, but power consumption and manufacturing complexity increase
Solution Approach 1:
The high-density display is segmented into many small independent facets that can be individually addressed and controlled. This segmentation allows for localized power management and processing, reducing the overall power consumption compared to a monolithic high-density display where all pixels must be controlled through complex centralized systems.
Solution Approach 2:
Each display facet operates with a degree of independence, with local processing capabilities that reduce the need for complex centralized control systems. This self-service approach minimizes the power required for signal transmission and processing across the entire high-density array.
