Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If detailed material information is provided for each region of the 3D model, then printing accuracy and material selection precision are improved, but file complexity and data volume increase
Solution Approach 1:
The patent divides the 3D model into multiple regions and assigns material information to each region separately. The file format includes region definitions with vertex indices and material identifiers, allowing precise material specification for different parts of the model without requiring a single complex material definition for the entire model.
Solution Approach 2:
The patent enables different material properties to be assigned to different regions of the 3D model. Each region can have its own material identifier, texture coordinates, and printing parameters, allowing local optimization of material selection based on specific regional requirements while maintaining overall model integrity.
2Reliability
If comprehensive material and design information is included in the 3D model file, then printing reliability is improved, but information transfer complexity increases
Solution Approach 1:
The patent creates a universal file format that can handle multiple types of information (material properties, texture coordinates, region definitions, vertex data) in a standardized structure. This multi-functional format ensures reliable information transfer across different 3D printing systems while maintaining consistent data organization and interpretation.
Solution Approach 2:
The standardized file format acts as an intermediary between the 3D model design and the printing process. It structures material and design information in a consistent format that facilitates accurate information transfer, reducing errors and ensuring reliable reproduction of the intended design.
3Adaptability or versatility
If material information is defined for each region, then adaptability for multi-material printing is improved, but file size and processing requirements increase
Solution Approach 1:
The patent segments the 3D model into regions with distinct material assignments. Each region contains vertex indices and material identifiers that reference a material library, allowing efficient storage of material information without duplicating data across the entire model.
Solution Approach 2:
The patent uses material identifiers and indices to reference material properties rather than storing complete material definitions for each region. This parameter-based approach maintains high adaptability for multi-material printing while significantly reducing the overall data volume required in the file.
