Engineering Contradiction Analysis
1Reliability
If a transparent display is rotated at high speed to display three-dimensional images, then three-dimensional images can be visually recognized from all directions, but the device size increases and becomes unsafe for outdoor use
Solution Approach 1:
Instead of rotating the display to create three-dimensional images, the patent inverts the approach by arranging light emitting elements in a fixed three-dimensional configuration from the outset. The multicolor light emitting elements are positioned at specific three-dimensional coordinates to directly form the three-dimensional image without requiring rotation, thereby eliminating the safety issues associated with high-speed rotation while maintaining the three-dimensional visualization capability.
Solution Approach 2:
The patent segments the display into multiple layers, each containing multicolor light emitting elements arranged in specific patterns. This segmentation allows the three-dimensional image to be constructed from multiple two-dimensional layers, eliminating the need for rotation while preserving the three-dimensional effect. The layered structure enables complex three-dimensional shapes to be formed by combining simpler layer configurations.
2Adaptability or versatility
If a transparent display is rotated to display complex three-dimensional shapes, then three-dimensional images can be displayed, but real-time rendering becomes difficult due to synchronization requirements
Solution Approach 1:
The patent pre-calculates and stores the positions and colors of light emitting elements for various three-dimensional shapes in advance. When a user selects a shape or inputs data, the system retrieves pre-computed three-dimensional image data and directly maps it to the corresponding light emitting elements. This preliminary preparation eliminates the need for real-time calculation during display, enabling instant switching between different three-dimensional shapes and achieving real-time rendering capability.
Solution Approach 2:
The patent implements a dynamic control system that can independently adjust the emission state of each multicolor light emitting element based on pre-stored three-dimensional image data. This dynamic control allows the display to rapidly switch between different three-dimensional configurations without mechanical movement, enabling real-time adaptation to user inputs and demonstrating high versatility in displaying various complex three-dimensional shapes.
3Shape
If multicolor light emitting elements are arranged three-dimensionally to form complex shapes, then three-dimensional images with volume can be displayed, but the number of elements and data complexity increase
Solution Approach 1:
The patent transitions from traditional two-dimensional display coordinates to three-dimensional spatial coordinates for arranging light emitting elements. By introducing the depth dimension and organizing elements in three-dimensional space, the system can represent complex three-dimensional shapes with volume. The patent uses three-dimensional coordinate systems and spatial relationships to efficiently manage and control the arrangement of elements, making the increased complexity manageable through dimensional organization.
Solution Approach 2:
The patent employs a hierarchical data structure where three-dimensional image data is organized in nested layers. Each layer contains two-dimensional arrays of light emitting element configurations, and these layers are stacked to form the complete three-dimensional structure. This nesting approach allows the system to manage complex three-dimensional data by breaking it down into manageable two-dimensional slices, reducing the perceived complexity while maintaining the ability to display volumetric three-dimensional images.
