Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hologram display technology is used to generate 3D content, then full realism and wavefront reconstruction are achieved, but device complexity and data processing requirements increase significantly
Solution Approach 1:
The patent segments the holographic display system into multiple sub-pixels (red, green, blue channels) arranged in specific patterns. Each sub-pixel handles a portion of the wavefront reconstruction, allowing complex holographic content to be generated through coordinated operation of simpler individual elements, thereby reducing overall device complexity while maintaining full realism
Solution Approach 2:
The patent introduces a temporal dimension by sequentially activating different sub-pixel groups for left and right eyes at different time intervals. This time-multiplexed approach allows binocular 3D holographic display without requiring simultaneous complex optical paths for both eyes, reducing spatial device complexity while preserving full realism
2Adaptability or versatility
If interactive capabilities are added to hologram display, then user engagement improves, but system complexity and processing requirements increase
Solution Approach 1:
The patent incorporates sensors that detect user presence, gaze direction, and interaction gestures, providing real-time feedback to the holographic display system. This feedback mechanism enables the system to dynamically adjust holographic content presentation without requiring complex manual controls, improving adaptability while managing system complexity through automated sensor-based control
Solution Approach 2:
The holographic display system automatically adjusts content parameters such as viewing angle, focal depth, and image position based on sensor-detected user characteristics and behavior. This self-adjusting capability provides interactive functionality without requiring complex user interface components, enhancing versatility while minimizing additional system complexity
3Ease of operation
If binocular hologram data is generated for wide viewing angle, then viewing comfort improves, but data processing time and computational load increase
Solution Approach 1:
The patent employs periodic time-multiplexed activation of left-eye and right-eye holographic data, displaying alternating frames at high temporal frequency. This periodic approach creates the perception of simultaneous binocular display, providing wide viewing angle and viewing comfort while reducing computational load by processing and displaying data sequentially rather than simultaneously
Solution Approach 2:
The patent selectively activates only the necessary sub-pixel groups for current viewing conditions, displaying full-resolution holographic data only when needed while using reduced data sets for other time intervals. This partial action approach maintains viewing comfort during critical display periods while reducing average data processing time and computational load
