Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional damping mechanism composed of multiple components with rubber buffers is used, then the structure can provide some damping effect, but the manufacturing and assembly procedure becomes more complicated and the axial damping effect is insufficient
Solution Approach 1:
The patent merges the damping function and buffering function into a single integrated damping device structure. The damping device includes a damping element and a buffering element combined within one unit, eliminating the need for separate rubber buffers and multiple components. This integration simplifies the overall structure while maintaining comprehensive damping effects in both axial and radial directions.
2Object-affected harmful factors
If multiple components with rubber buffers are used for damping, then some vibration buffering is achieved, but the manufacturing and assembly procedures are more complicated
Solution Approach 1:
The damping element and buffering element are combined into a single integrated component structure, reducing multiple separate parts into one manufacturable unit. This merger simplifies both manufacturing processes and assembly procedures while achieving comprehensive vibration buffering in axial and radial directions.
Solution Approach 2:
The damping device is designed to perform multiple functions simultaneously: it provides axial damping through the damping element, radial buffering through the buffering element, and structural support. This multi-functionality eliminates the need for separate components for each function, simplifying both manufacturing and assembly.
