Rotating Rail Module for Fuse-Disconnectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuse-disconnectors with rail modules lack the ability to rotate the rail module with integrated rail clamps, which limits the flexibility in changing the drainage direction without increasing the circuit breaker's height.
Innovation Solution
The rail module is designed with fourth and sixth sliding surfaces that shift on fourth pins, allowing the elastic arms to bend and rotate the rail clamps, enabling simultaneous removal and rotation, and a blocking-masking element secures the module in place, maintaining the drainage seal without increasing the circuit breaker's height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rail module is made fixed and non-rotatable, then the circuit breaker height is reduced, but the adaptability to change drainage direction is limited
Solution Approach 1:
The rail module is designed with rotating capability allowing it to change orientation dynamically. The elastic arms with sliding surfaces enable the rail module to rotate about the fourth pins, transforming from a fixed structure to a dynamic one that can adapt drainage direction while maintaining compact height through controlled rotation rather than linear extension
Solution Approach 2:
Instead of changing drainage direction through vertical height adjustment, the invention enables rotation in the horizontal plane. The rail module rotates about horizontal axes (fourth pins) to redirect drainage laterally, utilizing dimensional transformation to achieve adaptability without increasing the vertical dimension of the circuit breaker
2Adaptability or versatility
If the rail module is designed to rotate, then the adaptability to change drainage direction is improved, but the device complexity increases
Solution Approach 1:
The elastic arms serve dual functions: they provide mechanical support for the rail module and simultaneously act as rotation joints through their sliding surfaces on the fourth pins. By merging the support function and rotation function into a single integrated component, the invention reduces overall structural complexity while enabling rotational adaptability
Solution Approach 2:
The elastic arms automatically engage with the fourth pins through their sliding surfaces, creating a self-locking rotation mechanism. The elasticity of the arms provides both the mounting force and the rotation capability without requiring additional fastening mechanisms or complex control systems, allowing the rail module to be rotated and secured through simple manual manipulation

Function Achieved in This Case
This solution allows for easy rotation of the rail module, changing the drainage direction without height increase, ensuring secure mounting and efficient operation of the fuse-disconnector.
Implementation Method 1
the fourth sliding surfaces (124) of the rail module (48) shift on fourth pins (125) arranged on a connecting part (74) of the base part (34), which causes the first elastic arms (126) to bend

AI summary
The breaker has a rail module (48) including a rail clamp (49) for an assembly at a rail bridge. The rail module includes a first elastic arm (126), which is provided with a supporting surface (129) to be arranged in a base part. The rail module includes a second elastic arm (128), and/or is fixed on a component lower part (1), where the second elastic arm comprises another supporting surface (136) that is arranged in the base part. The second elastic arm hooks a pin, and the rail module includes a recess when pressing the second elastic arm.
