Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual methods are used for orthodontic simulation and tooth movement prediction, then treatment planning can be performed, but the accuracy and efficiency of simulating tooth movement and interproximal interval adjustments is insufficient
Solution Approach 1:
The patent replaces manual mechanical simulation methods with automated computer-based image processing. The system automatically detects tooth positions, calculates movement vectors, and simulates tooth movement through software algorithms, eliminating the need for manual manipulation of physical models or complex mechanical simulation devices while improving both accuracy and efficiency.
Solution Approach 2:
The patent creates digital copies of oral images and tooth structures that can be manipulated virtually. By generating accurate digital replicas of teeth and their positions, the system allows for precise simulation of tooth movement and interproximal interval changes without affecting actual teeth, enabling repeated simulations with different parameters for optimal treatment planning.
2Measurement precision
If complex simulation tools are developed to improve simulation accuracy, then tooth movement prediction becomes more precise, but the device complexity increases
Solution Approach 1:
The patent creates a multi-functional image processing system that performs multiple orthodontic simulation tasks using a unified platform. The same system can detect tooth positions, simulate movement in multiple directions, calculate interproximal intervals, and generate treatment predictions, eliminating the need for separate specialized tools for each function and reducing overall system complexity.
Solution Approach 2:
The system incorporates automated feature detection and calculation capabilities that perform tasks independently without requiring manual intervention. The image processing algorithms automatically identify tooth boundaries, calculate movement vectors, and adjust simulation parameters based on input images, reducing the complexity of user operation while maintaining high prediction precision.
