Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional press-brake bending of metal sheets is used to manufacture mold cores, then manufacturing process is relatively simple, but manufacturing precision and ability to achieve complex geometries deteriorates
Solution Approach 1:
The patent merges the mold core body and ventilation valve into a single integrated component made from wire mesh, eliminating the need for separate machining and assembly of ventilation valves. This integration achieves complex geometries including multi-axis curves while simplifying the overall manufacturing process by using a single material form for both structural and ventilation functions.
Solution Approach 2:
The patent changes the fundamental material parameter from solid metal sheets to wire mesh structure, enabling new geometric possibilities including complex multi-axis curves that cannot be achieved through traditional press-brake bending. This parameter change allows the material to be formed into intricate three-dimensional shapes while maintaining structural integrity.
2Device complexity
If separate machining and attachment of ventilation valves is used, then manufacturing process is simplified, but device complexity and assembly steps increase
Solution Approach 1:
The ventilation valve is merged with the mold core body into a single wire mesh structure, eliminating separate assembly steps. The wire mesh material inherently provides both the structural core and the ventilation openings, achieving integrated geometry without additional machining or attachment operations.
Solution Approach 2:
The wire mesh material serves multiple functions simultaneously: it provides the structural framework of the mold core, creates ventilation openings, and forms complex geometries including multi-axis curves. This multi-functionality eliminates the need for separate ventilation valve components and reduces assembly complexity.
3Manufacturing precision
If welded steel wire is used to create complex geometries, then manufacturing precision improves, but manufacturing time and process complexity increase
Solution Approach 1:
Changing from solid metal sheets to wire mesh structure enables complex geometries to be formed through wire welding processes that can more easily accommodate multi-axis curves and three-dimensional shapes. The wire mesh format allows for greater geometric flexibility while maintaining manufacturing efficiency through standardized wire forms and welding techniques.
Solution Approach 2:
The wire mesh structure acts as a composite form combining structural support and ventilation functions in a single material system. This composite approach allows complex geometries to be achieved through the inherent flexibility of wire construction rather than requiring complex machining operations on solid material.
4Ease of operation
If traditional metal sheet construction is used, then manufacturing process is simpler, but airflow efficiency and ease of separation deteriorates
Solution Approach 1:
The wire mesh structure creates a porous configuration with inherent openings that facilitate airflow through the mold core during concrete pouring. This porous structure also allows for easier separation of the molded block from the mold by enabling air to penetrate and break the vacuum seal, improving ease of operation without requiring complex ventilation valve mechanisms.
Solution Approach 2:
The ventilation function is merged into the basic structure of the wire mesh mold core, so that the same material configuration that provides structural support also provides airflow pathways. This integration improves separation ease through inherent porosity while avoiding the added complexity of separate ventilation valve systems.
