Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual labeling and segmentation methods are used for dental image analysis, then personnel can diagnose dental abnormalities using trained expertise, but the process is time-consuming and prone to human error
Solution Approach 1:
The patent replaces manual mechanical labeling and segmentation processes with an automated deep learning system. The neural network automatically performs tooth segmentation, labeling, and anomaly detection without requiring manual human intervention, thereby eliminating time loss while maintaining or improving diagnostic accuracy through consistent algorithmic application.
Solution Approach 2:
The system enables self-service automation where the dental imaging software autonomously performs image analysis, segmentation, and diagnosis without requiring continuous human oversight. The neural network processes images independently, automatically identifying teeth, applying labels, and detecting abnormalities, freeing personnel from repetitive manual tasks.
2Stability of the object's composition
If standardized templates are used for image layout and labeling, then consistency across images is improved, but the system cannot adapt to cases where the template does not contain the correct teeth number labels
Solution Approach 1:
The patent implements dynamic adaptability where the labeling system automatically adjusts to different patient anatomies and imaging scenarios. The neural network learns from training data and adapts its segmentation and labeling behavior based on the specific characteristics of each image, allowing the system to handle diverse cases without requiring manual template customization while maintaining consistent labeling standards.
Solution Approach 2:
The system changes labeling parameters dynamically based on image content analysis. Instead of applying fixed template labels, the neural network determines appropriate tooth labels and segmentation parameters automatically for each image based on detected features, enabling both consistency through standardized output formats and adaptability through content-driven parameter selection.
3Measurement precision
If heuristic algorithms are applied for feature detection prior to neural network processing, then specific features can be detected, but the system lacks flexibility when feature definitions need to change
Solution Approach 1:
The patent replaces rigid heuristic algorithms with a flexible deep learning neural network that automatically learns feature detection patterns from training data. This substitution eliminates the need for manual heuristic rule creation and updating, allowing the system to adapt to new feature definitions and dental conditions simply by retraining on new data, thereby maintaining both precision and flexibility.
Solution Approach 2:
The system performs preliminary learning during the training phase where the neural network pre-learns optimal feature detection patterns from labeled training images. This preliminary action embeds domain knowledge and feature detection capabilities directly into the network weights, enabling flexible adaptation to different feature types without requiring new heuristic algorithms for each feature category.
4Productivity
If filter settings are customized only during initial installation and applied to all images, then setup time is reduced, but the settings are not ideal for any specific image or patient condition
Solution Approach 1:
The patent implements dynamic filter settings that automatically adjust enhancement parameters based on each image's specific characteristics. The neural network analyzes input images and dynamically selects optimal contrast, gamma, sharpness, and other filter settings tailored to each patient's anatomy and image quality, eliminating the need for manual per-image adjustment while maintaining high enhancement quality.
Solution Approach 2:
The system performs self-service image enhancement by automatically determining optimal filter settings without requiring manual user configuration. The neural network autonomously analyzes each image and applies appropriate enhancement parameters, combining the efficiency of automated batch processing with the quality of customized per-image optimization.
