Solution Overview
Problem
Existing anti-vibration devices for machine tools, such as damping inserts and tubes, fail to provide high damping properties while minimizing material usage and production complexity, and often require high thicknesses that increase rigidity and environmental impact.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If high thicknesses are used in anti-vibration tubes, then rigidity is improved, but damping properties deteriorate
Solution Approach 1:
The anti-vibration device employs a polygonal outer surface with varying wall thickness, where thinner portions are positioned at specific locations to maximize flexibility and damping effectiveness. This local variation in thickness allows the structure to be more flexible where needed for vibration absorption while maintaining overall structural integrity.
2Strength
If high thicknesses are used in anti-vibration tubes, then structural integrity is improved, but material consumption increases
Solution Approach 1:
The device uses non-uniform wall thickness distribution with thinner sections strategically positioned to reduce material consumption. The polygonal geometry allows for optimized material placement, using less material in areas where high strength is not critical while maintaining structural integrity where needed.
Solution Approach 2:
The outer surface is segmented into multiple flat portions forming a polygonal cross-section, allowing different wall thicknesses in different segments. This segmentation enables precise control over material distribution, reducing overall material consumption while maintaining necessary structural properties.
3Stability of the object's composition
If annular bulges are created on the outer surface, then flexibility is improved, but production complexity increases
Solution Approach 1:
Instead of creating complex annular bulges, the invention uses a polygonal outer surface with flat portions that are simpler to manufacture. The varying thickness is achieved through the polygonal geometry itself rather than adding complex curved features, reducing production complexity while maintaining flexibility.
4Stability of the object's composition
If material is removed by turning to create annular bulges, then flexibility is improved, but production waste increases
Solution Approach 1:
The invention replaces the need for material removal by turning with a polygonal geometry that achieves flexibility through design rather than subtraction. The varying wall thickness is built-in during molding, eliminating the need for secondary turning operations and the associated material waste.
Solution Approach 2:
The wall thickness parameter is varied through the polygonal cross-section design rather than being uniform. This parameter variation is achieved during the molding process itself, eliminating the need for subsequent material removal operations that would generate waste.
