Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate radial damping devices and axial spring elements are used, then the spindle bearing device can provide radial damping and axial support, but the device complexity increases and the structure becomes more complex
Solution Approach 1:
The patent combines separate radial damping devices and axial spring elements into a single integrated bearing bushing element. The bearing bushing element incorporates both radial damping functionality and axial support functionality in one unified structure, eliminating the need for multiple separate components and reducing overall device complexity while maintaining the required functional performance.
Solution Approach 2:
The bearing bushing element is designed as a multi-functional component that simultaneously provides radial damping, axial support, and radial support functions. This universal component replaces what would traditionally require multiple specialized parts, simplifying the overall structure while ensuring reliable performance across multiple operational requirements.
2Reliability
If multiple separate components are used for axial and radial support, then the bearing can provide comprehensive support, but the number of components increases and maintenance needs increase
Solution Approach 1:
The patent merges multiple separate support components into a single integrated bearing bushing element that provides axial support, radial support, and radial damping in one unified structure. This integration reduces the total number of components that require maintenance and repair, while ensuring comprehensive support functionality is maintained through the multi-functional design of the bushing element.
3Reliability
If conventional separate damping and spring elements are used, then the bearing can provide damping and springing, but the design becomes more complex and space-consuming
Solution Approach 1:
The patent combines separate damping elements and spring elements into a single integrated bearing bushing element. This merging of functions into one compact component reduces the overall space required compared to having separate damping and springing components, while maintaining the necessary damping and springing characteristics through the bushing element's design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies the design, reduces maintenance needs, and maintains performance stability across varying temperatures, ensuring optimal radial return and damping without significant changes in running properties.
Implementation Method 1
the common bearing bushing element is mounted both axially and radially on a housing sleeve of the spindle bearing device by means of at least one axial-radial support element designed in one piece and elastically
Implementation Method 2
there is a gap for a damping fluid between the inner wall or the outer wall of the bearing bushing element on the one hand and the axial-radial support element on the other. The damping fluid in the gap ensures that the radial return of the spindle is optimally damped
