Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the machine bed is made from cast mineral (polymer concrete), then the tensile and compressive strength is improved, but the production complexity and cost increase
Solution Approach 1:
The machine bed is divided into a base body made of fiber concrete and a separate connection section, which are aligned and glued together. This segmentation allows the use of simpler, more cost-effective fiber concrete while maintaining structural integrity through the modular assembly approach.
Solution Approach 2:
The invention uses fiber concrete, a composite material consisting of cement binder and fiber reinforcement, to create the machine bed. This composite material provides the necessary tensile and compressive strength while being more economical and simpler to produce than cast mineral.
2Ease of manufacture
If the machine bed is made from traditional steel or sheet steel, then the production process is simple, but the dynamic properties and vibration behavior are insufficient
Solution Approach 1:
Fiber concrete serves as a composite material that combines the simplicity of cement-based production with superior dynamic properties. The fiber reinforcement within the concrete matrix provides excellent vibration damping characteristics while maintaining ease of manufacture through conventional concrete casting techniques.
Solution Approach 2:
The invention changes the material parameters by using fiber concrete with specific fiber content and distribution, achieving optimal dynamic properties and vibration behavior while maintaining production simplicity. The fiber reinforcement alters the mechanical parameters of the concrete to match or exceed traditional steel performance.
3Manufacturing precision
If the connection section is aligned and glued to the base section, then the manufacturing precision is improved, but the production time increases
Solution Approach 1:
The connection section is pre-aligned using an alignment station before the gluing process. This preliminary alignment action ensures high dimensional accuracy of the finished machine bed while allowing the gluing operation to proceed efficiently without requiring extensive adjustment time afterward.
Solution Approach 2:
The alignment station serves as an intermediary device that facilitates precise positioning of the connection section relative to the base section before permanent bonding. This intermediary tool enables high manufacturing precision without significantly extending the overall production cycle.
