Engineering Contradiction Analysis
1Reliability
If conventional dynamic dampers are designed to reduce both axial and radial vibrations, then vibration reduction capability is improved, but production cost increases due to large number of parts and complex structure
Solution Approach 1:
The patent merges the functions of multiple separate vibration reduction components into a single integrated elastic body. The elastic body simultaneously provides axial vibration reduction through its longitudinal deformation capability and radial vibration reduction through its radial deformation capability, eliminating the need for separate dampers for each direction and thereby reducing part count and structural complexity
Solution Approach 2:
The elastic body is designed as a multi-functional component that performs multiple vibration reduction functions. By incorporating inclined surfaces at specific angles (45 degrees) and designing the elastic body with appropriate dynamic stiffness characteristics in both axial and radial directions, a single component achieves what previously required multiple specialized components
