Switching Device Arrangement with External Drive and Spacer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switching device arrangements require a large amount of space due to complex kinematic chain guidance and limited access, which compromises reliability.
Innovation Solution
A compact switching device arrangement with a distancing device attached to a bulged wall of the encapsulating housing, allowing the drive device to be external while transmitting movement via a kinematic chain, and using a spacer device to create a receiving space that can accommodate different drive devices and protect the kinematic chain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two drive devices are aligned in opposite directions to use identical parts, then the construction can be standardized, but the space requirement increases and the kinematic chain guidance becomes complex
Solution Approach 1:
The patent combines two drive devices and their kinematic chains into a single integrated arrangement. The two drive devices are positioned on opposite sides of the encapsulating housing and work together to operate multiple circuit breakers, sharing common components such as the kinematic chain guidance structure and mounting arrangement, thereby reducing overall space requirements while maintaining standardization.
Solution Approach 2:
The patent utilizes the spatial dimension by positioning drive devices on opposite sides of the encapsulating housing and arranging kinematic chains to extend through the housing structure. This three-dimensional arrangement allows efficient use of space by distributing components along different spatial axes rather than stacking them linearly.
2Adaptability or versatility
If two drive devices are aligned in opposite directions to use identical parts, then the construction can be standardized, but the kinematic chain guidance becomes complex and access is limited
Solution Approach 1:
The patent extracts the kinematic chain guidance structure from the interior of the encapsulating housing and positions it on the exterior surface. This allows direct access to the kinematic chains for maintenance and adjustment without disassembling the housing, while the drive devices remain mounted on opposite sides to maintain standardization.
Solution Approach 2:
The patent introduces an intermediary mounting structure that connects the drive devices to the kinematic chains on the exterior of the housing. This intermediary arrangement facilitates easy access and adjustment of the kinematic chains while maintaining the standardized opposite-side configuration of the drive devices.
3Volume of moving object
If the drive device is placed outside the encapsulating housing, then the interior volume is preserved, but a distancing device is required to create a receiving space
Solution Approach 1:
The distancing device serves multiple functions: it creates the receiving space for the drive device, provides mechanical mounting support, ensures proper alignment between the drive device and kinematic chain, and maintains the structural integrity of the housing assembly. This multi-functionality reduces the need for additional separate components.
4Strength
If the distancing device encloses the bulged wall, then mechanical protection is improved, but the overall dimensions increase
Solution Approach 1:
The distancing device is designed to nest around the bulged wall of the encapsulating housing, utilizing the existing structural protrusion as part of the mounting arrangement. This nested configuration provides mechanical protection and structural support without requiring additional external space, as the distancing device integrates with rather than adds to the housing dimensions.
