Vacuum Switch Operating Device Height Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum switches have a large operating device height due to the placement of auxiliary contacts and other components above the electromagnet, which complicates installation and reduces convenience.
Innovation Solution
The operating device is redesigned with the electromagnet fixed to the lateral side of the case, allowing the capacitor and control board to be mounted on either side, reducing the overall height and improving installation workability by optimizing the layout and fixing mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the auxiliary contact and other components are located above the electromagnet and integrated with the electromagnet, then the structural integration is improved, but the overall height of the operating device increases
Solution Approach 1:
The patent redistributes components from a vertical stacking arrangement to a horizontal distribution across multiple sides of the case. The electromagnet is fixed to the front side, the capacitor to one lateral side, and the control board to the opposite lateral side, transforming the spatial arrangement from vertical to multi-dimensional horizontal placement, thereby reducing overall height while maintaining structural integration.
2Shape
If the electromagnet is located in the central lower part of the case, then the structural symmetry is improved, but the installation convenience deteriorates
Solution Approach 1:
The patent segments the internal space of the case into distinct functional zones: the front side for the electromagnet, one lateral side for the capacitor, and the opposite lateral side for the control board. This segmentation allows each component to be independently positioned and installed, improving installation convenience while maintaining a balanced structural layout.
3Volume of moving object
If the capacitor and control board are placed on both sides of the electromagnet, then the space utilization is improved, but the flux leakage increases
Solution Approach 1:
The patent introduces a non-magnetic plate as an intermediary barrier between the electromagnet and the capacitor/control board positioned on the lateral sides. This non-magnetic plate prevents magnetic flux from leaking into the adjacent electronic components while allowing the compact lateral arrangement that optimizes space utilization within the case.
