Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional coating deposition methods are used, then coatings can be formed on mold surfaces, but the coatings are uneven and reactants are wasted
Solution Approach 1:
The filament assembly is divided into multiple individual filaments arranged in an array, with each filament independently positioned and oriented. This segmentation allows precise control over the gaseous species flow path, directing it parallel to each filament surface to ensure uniform coating deposition while minimizing reactant waste through optimized flow distribution across all filaments
Solution Approach 2:
The system employs a non-planar filament array where individual filaments are positioned at specific locations and orientations tailored to the mold geometry. Each filament is locally optimized to direct gaseous species flow parallel to its surface, ensuring uniform coating quality at each location while reducing overall reactant consumption through precise spatial distribution
2Adaptability or versatility
If complex mold geometries are coated, then comprehensive coverage is achieved, but coating uniformity becomes difficult to maintain
Solution Approach 1:
The filament array is configured with curved and angled filament orientations that match the curvature of non-planar mold surfaces. This allows the gaseous species flow to remain parallel to the filament surfaces even on curved geometries, maintaining coating uniformity across complex three-dimensional mold shapes while achieving comprehensive surface coverage
Solution Approach 2:
The system transitions from a planar filament arrangement to a three-dimensional non-planar configuration that conforms to complex mold geometries. By adding spatial dimensions and varying filament orientations in multiple directions, the system achieves uniform coating deposition on surfaces with complex curvature while maintaining adaptability to various mold shapes
