Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical fabrication of jaw models and dental restorations is performed to determine insertion paths, then verification accuracy is improved, but time consumption and cost increase
Solution Approach 1:
The patent creates a digital copy (virtual model) of the jaw and dental restoration instead of using physical models. The virtual model includes digital representation of the jaw structure and restoration geometry, allowing insertion path verification to be performed computationally, thereby eliminating the need for time-consuming physical model fabrication while maintaining verification accuracy
Solution Approach 2:
The patent replaces the mechanical system of physical model fabrication and manual insertion testing with a computational system. The computer calculates the insertion path by processing digital models and determining optimal insertion trajectories algorithmically, substituting physical manipulation with digital computation to reduce time consumption
2Measurement precision
If physical fabrication of jaw models and dental restorations is performed to determine insertion paths, then verification accuracy is improved, but cost increases
Solution Approach 1:
The patent uses digital copies of the jaw and restoration instead of physical models. The virtual model allows repeated verification without additional material costs, eliminating expenses related to physical model materials, fabrication equipment, and disposal, while maintaining verification accuracy through computational analysis
Solution Approach 2:
The patent changes the state of the model from physical to digital, fundamentally altering the verification process parameters. The digital model can be manipulated, measured, and analyzed computationally without consuming physical materials, thereby reducing manufacturing costs while preserving verification accuracy
3Productivity
If physical fabrication methods are used to determine insertion paths, then verification can be performed, but precision decreases
Solution Approach 1:
The patent replaces manual physical verification with automated computational calculation. The computer processes digital models to precisely calculate insertion paths, avoiding human error and physical measurement limitations, thereby improving both efficiency and precision simultaneously
Solution Approach 2:
The patent performs preliminary digital verification before physical manufacturing. By calculating the insertion path in advance using digital models, the system identifies and corrects potential issues before physical fabrication, ensuring higher precision without requiring iterative physical adjustments
