Innovation Solution
A switching apparatus design featuring a breaking assembly, actuation assembly, and middle cover that facilitate detachable coupling and energy transmission, with positioning brackets and auxiliary positioning parts ensuring accurate alignment and stability, allowing for easier maintenance and improved reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional switches are used under high-load conditions, then the switch can operate, but the actuation assemblies require periodic maintenance and inspection, reducing reliability and service life
Solution Approach 1:
The switch is divided into separate assemblies: a breaking assembly and an actuation assembly that can be detachably coupled. The actuation assembly can be independently removed and replaced without disassembling the entire switch, enabling easy maintenance and inspection of actuating components under high-load conditions
Solution Approach 2:
The coupling between the breaking assembly and actuation assembly is designed to be detachable rather than fixed. This allows the actuation assembly to be dynamically separated from the breaking assembly for maintenance purposes, then reconnected to restore full functionality, improving serviceability without compromising operational reliability
2Stability of the object's composition
If conventional switch actuation assemblies are designed for stability, then they can withstand high-load usage, but they become difficult to assemble and disassemble, increasing maintenance time and resources
Solution Approach 1:
The actuation assembly is designed as a separate, detachable unit from the breaking assembly. This segmentation allows maintenance personnel to quickly remove and replace only the actuation assembly without affecting the stable breaking assembly, significantly reducing maintenance time while preserving the stability needed for high-load operation
Solution Approach 2:
The actuation assembly is positioned within or adjacent to the breaking assembly structure, allowing it to be nested or integrated during operation for stability, yet designed with coupling mechanisms that enable easy extraction when maintenance is required, balancing stability with serviceability
