Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional manufacturing methods are used for dental elements, then manufacturing simplicity is maintained, but geometric precision and fitting accuracy deteriorate due to unintended deviations
Solution Approach 1:
The patent creates a digital copy (3D digital model) of the physical dental element and uses this copy for virtual checking and adjustment. The digital model serves as a precise replica that can be manipulated and compared without affecting the physical element, enabling high-precision geometric verification while keeping the physical manufacturing process relatively simple.
Solution Approach 2:
The patent introduces an augmented reality interface as an intermediary between the physical dental element and the checking process. The AR system overlays digital information onto the physical element, allowing operators to see geometric deviations and adjustments in context without complex physical measurement apparatus directly interfering with the manufacturing process.
2Manufacturing precision
If geometric form adjustments are made to correct deviations, then fitting accuracy improves, but time consumption increases due to iterative checking and adjusting
Solution Approach 1:
The patent implements continuous real-time tracking and visualization of the dental element's geometric form. Instead of periodic discrete measurements, the system continuously monitors and displays geometric deviations as the element is manipulated, allowing for immediate detection and correction without interrupting the workflow, thus reducing overall checking time while maintaining high precision.
Solution Approach 2:
The system provides immediate visual feedback through the augmented reality interface, showing operators real-time information about geometric deviations and required adjustments. This feedback loop enables rapid iterative corrections without time-consuming manual measurements or waiting for analysis, significantly reducing the time needed to achieve precise fitting accuracy.
3Manufacturing precision
If detailed geometric checking is performed, then fitting quality improves, but operational complexity increases due to multiple measurement parameters
Solution Approach 1:
The patent replaces complex mechanical measurement systems with optical sensing and computer vision technology. The optical sensor device automatically captures geometric data and the system processes multiple measurement parameters through software algorithms, eliminating the need for operators to manually manage complex mechanical measurement apparatus while achieving detailed geometric verification.
Solution Approach 2:
The augmented reality interface serves multiple functions simultaneously: it displays geometric deviations, guides adjustments, provides measurement data, and confirms fitting accuracy all through a single unified interface. This multi-functional approach consolidates what would otherwise require multiple separate checking procedures into one integrated operation, maintaining detailed geometric checking while improving ease of operation.
