Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional CAD/CAM systems are used to create data records for dental prostheses, then the shape and surface description is achieved, but additional information such as production accuracy, material, and color attributes cannot be incorporated
Solution Approach 1:
The data record is segmented into multiple entry types (first entries for shape/surface description, second entries for attributes) organized in a hierarchical structure. This allows comprehensive information storage while maintaining systematic organization and manageability of the complex data.
Solution Approach 2:
The patent adds a new dimension to the traditional 3D geometric data by incorporating attribute information (production accuracy, material, color) as a fourth dimension of data description. This transforms the data structure from purely spatial to include manufacturing and material properties.
2Adaptability or versatility
If only shape information is stored in data records, then the data structure remains simple, but specialized prostheses requiring additional manufacturing information cannot be produced
Solution Approach 1:
Attributes are assigned to specific elements (vertices, edges, facets) of the dental prosthesis model, allowing different production parameters to be specified for different regions. This enables localized control of manufacturing precision and material properties where needed.
Solution Approach 2:
All manufacturing information including production accuracy, material, and color attributes is pre-defined and stored in the data record before the manufacturing process begins. This preliminary preparation enables precise control during production without requiring real-time adjustments.
3Manufacturing precision
If attributes are manually assigned to each element, then customization is possible, but the process becomes time-consuming
Solution Approach 1:
The system automatically assigns attributes to elements based on predefined criteria and rules, reducing manual intervention. The computer system performs self-service by examining the model and automatically setting corresponding attributes, significantly reducing time consumption while maintaining accuracy.
Solution Approach 2:
The system provides feedback mechanisms that allow verification and adjustment of automatically assigned attributes. Users can review the assigned attributes and make corrections if needed, ensuring accuracy while minimizing manual time investment.
