Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cameras or an array of cameras are used to obtain symmetrical images for stereoscopic matching, then stereoscopic vision can be achieved, but the device size and computational cost increase significantly
Solution Approach 1:
The compound eye is divided into multiple independent ommatidia, each with its own optical element and photosensitive units. Each ommatidium functions as an independent imaging unit, capturing light from different directions simultaneously. This segmentation allows the system to achieve stereoscopic vision without requiring multiple separate camera systems, thereby reducing overall device size and computational complexity while maintaining reliable three-dimensional space information acquisition
Solution Approach 2:
The patent creates an artificial compound eye structure that copies the biological compound eye design found in insects. Instead of using multiple traditional cameras, the system replicates the natural compound eye architecture with multiple small optical elements (ommatidia) arranged in a specific pattern, each focusing light onto corresponding photosensitive units. This copying approach achieves the same stereoscopic function with significantly reduced device complexity
2Measurement precision
If traditional optical systems are used, then imaging can be achieved, but the view angle and sensitivity are limited
Solution Approach 1:
The patent transitions from traditional two-dimensional imaging to three-dimensional立体 imaging by arranging multiple ommatidia in spatial dimensions. Each ommatidium captures light from a specific direction, and the collective arrangement of these ommatidia provides a wide field of view and depth information simultaneously. This dimensional approach enables the system to achieve both high imaging accuracy and enhanced adaptability in terms of view angle and sensitivity
