Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uniform boreholes are used in lamella blocks, then manufacturing is simplified, but cooling efficiency is insufficient and production costs increase
Solution Approach 1:
The patent applies local quality by providing different opening geometries in different regions of the lamella block. Each lamella contains openings with specific cross-sectional shapes (circular, rectangular, triangular) and sizes tailored to the local cooling requirements, rather than using uniform boreholes throughout. This allows optimized cooling efficiency in each region while maintaining manufacturability through 3D printing capabilities.
Solution Approach 2:
The patent changes the geometric parameters of the openings (cross-sectional shape, size, orientation) to optimize cooling performance. By varying these parameters across different lamellae and regions, the system achieves superior cooling efficiency compared to uniform boreholes, while the 3D printing process enables cost-effective production of these complex geometries.
2Temperature
If variable geometry openings are implemented in each lamella, then cooling efficiency is optimized, but manufacturing complexity increases
Solution Approach 1:
The patent utilizes parameter changes by systematically varying opening geometries (cross-sectional shape, dimensions, orientation) to match the specific cooling requirements of each lamella region. This optimized cooling performance is achieved through 3D printing, which can manufacture these variable geometries without significant complexity increase, as the process natively handles complex shapes.
Solution Approach 2:
The patent replaces traditional mechanical manufacturing methods (which would find variable geometries complex and costly) with additive manufacturing/3D printing. This substitution enables cost-effective production of lamella blocks with variable opening geometries, as the 3D printing process can directly create complex shapes from digital models without requiring additional machining or assembly steps.
3Ease of manufacture
If standardized opening designs are used across all lamellae, then production costs are reduced, but cooling performance does not meet varying requirements
Solution Approach 1:
The patent implements local quality by designing openings with different cross-sectional shapes and sizes in different lamella regions based on specific cooling requirements. Each lamella's opening geometry is tailored to its functional needs, ensuring reliable cooling performance throughout the block while maintaining cost-effectiveness through efficient 3D printing manufacturing.
