Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large amounts of dental cement are applied to ensure adequate adhesion, then the adhesion reliability is improved, but the loss of substance increases due to excess cement waste and gum irritation
Solution Approach 1:
The patent applies preliminary action by pre-calculating the exact volume of cement needed based on the digital model of the restoration element and mounting structure before application. The system determines the precise cement quantity required to fill the gap between surfaces, eliminating the need to apply large amounts and then remove excess. This preliminary calculation and controlled application directly reduces cement waste while ensuring adequate adhesion.
Solution Approach 2:
The patent replaces the traditional mechanical manual application method with a digital computational system. The system uses digital models, computational algorithms, and automated calculation to determine the exact cement volume needed, replacing the mechanical process of visually estimating and manually applying large amounts of cement. This substitution enables precise control over cement quantity, reducing waste while maintaining adhesion reliability.
2Reliability
If large amounts of dental cement are applied to ensure adequate adhesion, then the adhesion reliability is improved, but the object-affected harmful factors increase due to cement adhering to gum lines causing irritation or decay
Solution Approach 1:
The system performs preliminary calculation of the exact cement volume needed based on digital models before application. By knowing the precise amount required to fill the gap between the restoration element and mounting structure, the system prevents over-application that would cause cement to adhere to gum lines. This preliminary planning eliminates the harmful effect of excess cement while ensuring adequate adhesion.
Solution Approach 2:
The patent implements feedback through digital modeling and computational verification. The system uses digital models of the restoration element and mounting structure to calculate the exact gap volume, then verifies the cement quantity before application. This feedback loop ensures that only the precise amount needed is applied, preventing gum line contamination while maintaining reliable adhesion.
3Manufacturing precision
If digital models and computational systems are used to calculate cement volume, then the manufacturing precision and application accuracy are improved, but the device complexity increases
Solution Approach 1:
The patent uses digital models as copies of the physical restoration element and mounting structure. Instead of working with the actual complex geometries during calculation, the system creates digital representations that can be precisely measured and processed computationally. This copying approach simplifies the complexity of the physical forms while maintaining manufacturing precision in cement volume calculation and application.
