Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positive space labeling is used to train computer vision systems, then object identification can be achieved, but accuracy is insufficient and training is time-consuming
Solution Approach 1:
The patent inverts the traditional labeling approach by focusing on negative space (background) labeling instead of positive space (object) labeling. The system labels the background regions and uses this information to infer object boundaries and characteristics, which significantly improves training efficiency and accuracy while reducing the time required for annotation.
Solution Approach 2:
The patent extracts and utilizes shadow information from images as a key feature for object detection and movement prediction. By separating and analyzing shadow regions from the main image data, the system achieves improved object recognition accuracy without requiring additional computational resources for complex analysis.
2Measurement precision
If expensive equipment is used for light variation analysis, then measurement precision can be improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces expensive specialized equipment with standard cameras and computational algorithms. The system uses off-the-shelf imaging devices combined with image processing techniques to analyze light variations and shadows, achieving comparable or superior measurement precision without the complexity and high cost of specialized hardware.
Solution Approach 2:
The patent substitutes physical measurement equipment with digital image processing. Instead of using specialized sensors or instruments to measure light variations directly, the system captures images with standard cameras and uses computational algorithms to extract shadow and light variation information, thereby reducing device complexity and cost.
3Adaptability or versatility
If traditional object recognition methods are used, then basic identification can be achieved, but movement prediction capability is insufficient
Solution Approach 1:
The patent analyzes shadow information and light variations in advance to predict object movement before it occurs. By examining the temporal changes in shadow positions and light patterns, the system can infer object motion and predict future positions, enhancing both adaptability and reliability of movement prediction.
