Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If signal light indicative of a single image is inputted into a light diffraction element, then optical computing can be performed with high speed and low electric power consumption, but information that cannot be obtained from only a single image (such as three-dimensional information) cannot be processed
Solution Approach 1:
The patent combines multiple images (first image and second image) into a single composite image that contains information from both source images. This composite image is then processed by the light diffraction element, enabling the system to handle three-dimensional information and other data that cannot be obtained from a single image while maintaining the benefits of optical computing
Solution Approach 2:
The patent transitions from processing single two-dimensional images to processing composite images that encode multi-dimensional information (such as depth information from stereo images). By encoding multiple images into a composite structure, the system gains the ability to process three-dimensional data through the same optical computing architecture
2Adaptability or versatility
If a conventional optical computing device processes only single image information, then the device structure remains simple, but the device cannot utilize multi-modal or three-dimensional information
Solution Approach 1:
The patent divides the image processing task into segments: first image acquisition, second image acquisition, composite image generation, and optical computing processing. By segmenting the workflow and using a light emitting section to generate signal light from the composite image, the system achieves multi-image processing capability while keeping each individual component relatively simple
