Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If subsidiary raw materials are crushed after natural cooling, then they can be processed into smaller particles, but dust is generated causing environmental pollution and material loss
Solution Approach 1:
The casting process divides the molten material into multiple small cavities simultaneously, creating uniformly sized particles directly during solidification. This segmentation eliminates the need for subsequent crushing operations that generate dust, while maintaining processing efficiency through parallel casting in multiple cavities.
Solution Approach 2:
The system performs the size-reduction action during the casting process itself rather than after solidification. By forming particles of desired size directly in the mold cavities while the material is still molten, the harmful crushing operation is eliminated entirely, preventing dust generation at its source.
2Manufacturing precision
If crushing process is used to reduce particle size, then uniform particles can be obtained, but irregular particles and dust are generated
Solution Approach 1:
The mold is divided into multiple cavities of identical dimensions, each forming a particle of uniform size. This segmentation approach creates consistent particle geometry directly during solidification, eliminating the irregular particles and dust that result from mechanical crushing of larger lumps.
Solution Approach 2:
The invention changes the physical state parameter from solid-to-particle through crushing to liquid-to-solid through controlled casting. By utilizing the fluid state during forming, the material takes the exact shape of the cavity without internal stresses or irregularities that would require subsequent crushing, thereby eliminating dust generation while achieving uniform particle size.
3Manufacturing precision
If molten material is cast in molds, then unit size materials can be produced, but leakage between molds may occur
Solution Approach 1:
A gate structure acts as an intermediary component between the material supply and the individual cavities. The gate controls the flow of molten material into each cavity sequentially, preventing direct exposure to atmospheric conditions and eliminating leakage between molds while maintaining consistent unit size production.
Solution Approach 2:
The mold design incorporates a flexible or expandable cavity structure that can adapt to the volume of molten material. As material fills the cavity, the flexible walls conform to the material volume, preventing leakage while ensuring each unit achieves consistent dimensional characteristics upon solidification.
