Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional manufacturing methods are used to produce hollow components with complex shapes, then manufacturing precision can be achieved, but device complexity increases and productivity decreases
Solution Approach 1:
A soluble substrate (core) is created in advance with the desired complex geometry, then coated with electrically conductive material. The substrate is subsequently dissolved to leave the hollow component. This preliminary formation of the complex shape via substrate manufacturing avoids complex hollow-forming tooling.
Solution Approach 2:
A soluble substrate acts as an intermediary or template during manufacturing. It provides the complex external geometry, is coated with the conductive layer, and then removed by dissolution. This intermediary enables complex hollow shapes without requiring complex mold cavities.
2Device complexity
If additive production methods are used to produce hollow components with complex shapes, then device complexity is reduced, but manufacturing precision and surface quality deteriorate
Solution Approach 1:
The mechanical additive layering process is replaced with a coating process applied to a pre-formed substrate. The substrate provides the complex geometry through conventional manufacturing, while the coating process (electroplating, CVD, PVD, or thermal spraying) deposits the conductive material with high surface quality and precision.
3Productivity
If thin wall thicknesses are achieved in hollow components, then productivity and material efficiency improve, but manufacturing precision and structural strength deteriorate
Solution Approach 1:
The wall thickness is controlled by adjusting coating parameters such as deposition time, current density (for electroplating), or spray parameters. This allows precise control of thin wall thicknesses while maintaining structural integrity through optimized material properties of the coating layer.
4Power
If efficient cooling is implemented in electrical conductors, then current density increases, but device complexity increases due to additional cooling structures
Solution Approach 1:
The hollow cavity structure serves multiple functions: it provides the load-bearing structural element and simultaneously acts as a cooling channel. The same geometric feature that enables structural integrity also enables efficient heat removal, eliminating the need for separate cooling structures.
Solution Approach 2:
The cooling fluid pathway is nested within the hollow cavity of the conductor itself. The coolant flows through the internal cavity, allowing heat removal from the conductive wall while the conductor maintains its structural form. This nested arrangement integrates cooling functionality within the conductor geometry.
