Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional holographic image technologies are used to generate 3D images, then depth information can be captured, but the focal plane cannot be adjusted dynamically and image quality degrades when perspectives change
Solution Approach 1:
The patent applies dynamics by enabling the focal plane to change dynamically based on detected subject features. The system processes images from multiple perspectives, detects subject features, and adjusts the focal plane in real-time to maintain subject focus across different viewing angles, transforming the static focal plane of traditional holographic systems into a dynamic one that adapts to content requirements
Solution Approach 2:
The patent implements feedback by using detected subject features to inform focal plane adjustments. The system continuously analyzes images from the photoset, identifies subject features, and uses this information to determine optimal focal plane positions, creating a closed-loop system that maintains image quality consistency while enabling focal plane adaptability
2Productivity
If depth information is used in traditional holographic processing, then 3D perception is achieved, but real-time focal plane adjustments are computationally complex and time-consuming
Solution Approach 1:
The patent applies taking out by extracting only the essential subject features from the images rather than processing complete depth information. By detecting and isolating key subject features, the system reduces the computational burden while maintaining the ability to perform real-time focal plane adjustments, effectively removing unnecessary processing complexity
Solution Approach 2:
The patent implements partial action by performing focal plane adjustments based on subject feature detection rather than comprehensive depth map processing. This selective approach processes only the necessary portions of the image data required for focal plane determination, reducing overall processing complexity while maintaining real-time capability
3Measurement precision
If multiple perspectives are captured to improve 3D perception, then lightfield information is enhanced, but aligning features across images becomes more difficult
Solution Approach 1:
The patent applies preliminary action by detecting subject features from the photoset before performing the alignment operation. By pre-identifying subject features across multiple perspectives, the system establishes reference points that guide the subsequent alignment process, making feature alignment more accurate and manageable despite the complexity of multiple perspectives
