Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-voltage system components face challenges in efficiently compensating for vibrations and material stresses during transport, assembly, and operation, particularly due to external loads and thermal expansion, which existing damping methods fail to address effectively.
Innovation Solution
A device comprising a piston and housing movable within a high-voltage system filled with a viscous medium, where the piston is coupled to the component and the housing, and a spring connects the piston to the housing, allowing the medium to flow in and out, providing hydraulic damping and effectively absorbing shocks and stresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional damping components are added to compensate for vibrational loads, then vibration compensation effectiveness is improved, but device complexity and additional material requirements worsen
Solution Approach 1:
The viscous medium already present in the high-voltage system performs multiple functions: electrical insulation and vibration damping. The piston-housing assembly utilizes this existing medium to provide damping without requiring separate damping components, thus improving vibration compensation while avoiding additional complexity
Solution Approach 2:
The system uses its own existing viscous medium to compensate for vibrations, rather than requiring external damping materials. The medium serves the system's own damping needs, eliminating the need for additional components and reducing overall system complexity
2Strength
If traditional cushioning elements are used for shock absorption, then shock load compensation is improved, but adaptability to additional vibrational loads during operation worsens
Solution Approach 1:
The damping system is dynamic rather than static. The piston can move within the housing to change the volume of viscous medium, allowing the system to adapt to varying vibrational loads during operation. This dynamic adjustment capability enables the system to respond effectively to both shock loads and continuous vibrations
Solution Approach 2:
The system employs hydraulic damping principles by utilizing the viscous medium to resist piston movement. The fluid dynamics provide adaptive damping that automatically adjusts to different vibration frequencies and amplitudes, enhancing versatility across various operational conditions
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 device securely mounts high-voltage system components by combining fluid dynamics with spring damping, efficiently attenuating vibrations and compensating for internal stresses, such as thermal deformations, using existing insulating liquids like oil, without requiring additional damping media.
Implementation Method 1
the spring may be elastically deformed
Implementation Method 2
a viscous medium which is preferably already present in the high-voltage system can be used for hydraulic damping
Implementation Method 3
the combination of the fluid dynamics of the medium and the damping properties of the spring can have the effect that a component in a high-voltage system can be mounted securely, since for example shocks can be absorbed

AI summary
A device for compensating for vibration and/or material stress of a component of a high-voltage system filled with a viscous medium includes a piston and a housing. A first end piece of the piston may be coupled to the component of the system. A second end piece of the piston may be at least partly within the housing and enclosed thereby, enabling movement of the piston and the housing in opposite directions along an axis. The second end piece may be coupled to an inner wall of the housing by at least one spring. The piston and the housing are surrounded by the medium filling the system. A method and computer program product for computer-aided design of a device for compensating for vibration and/or material stress of a component of the system filled with a viscous medium are also provided.
