Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual mapping is used to correlate 2D and 3D dental images, then the process is simple to perform, but the precision and reliability of the mapping are reduced
Solution Approach 1:
The patent replaces the manual mechanical mapping process with an automated computer-implemented system that uses image processing algorithms and geometric morphometrics to calculate scaling factors and align 2D and 3D dental images, thereby eliminating human judgment variability while maintaining operational simplicity
Solution Approach 2:
The patent creates a virtual 2D digital image as a copy from the 3D digital model, then performs automated scaling factor estimation by comparing landmarks between the virtual 2D image and the actual 2D image, enabling precise mapping without manual intervention
2Productivity
If manual mapping is used to correlate 2D and 3D dental images, then the system complexity is low, but the time and effort required for treatment planning increases
Solution Approach 1:
The system performs self-service by automatically identifying landmarks, calculating geometric morphometrics, and determining scaling factors without requiring manual intervention, thereby reducing the time and effort needed for 2D-3D image correlation while improving treatment planning productivity
Solution Approach 2:
The patent performs preliminary actions by pre-processing the 3D digital model to create a virtual 2D image and pre-identifying landmarks before the actual mapping process, which streamlines the subsequent scaling factor estimation and reduces overall treatment planning time
3Reliability
If manual mapping is used, then the ease of operation is high, but the reliability and reproducibility of the mapping process deteriorates
Solution Approach 1:
The patent replaces manual operational processes with automated computer-implemented algorithms that consistently apply geometric morphometrics and scaling factor calculations, eliminating human judgment variability and improving mapping reliability while maintaining ease of operation through automated workflows
Solution Approach 2:
The system uses feedback by comparing landmarks identified in both 2D and 3D images, calculating scaling factors based on geometric morphometrics, and iteratively refining the mapping to achieve accurate correlation, thereby ensuring reliable and reproducible results
