Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switching devices face challenges in being easily equipped or retrofitted with electronic components, particularly in confined spaces with poor lighting, where accessing weight-intensive components is difficult.
Innovation Solution
A switching device design featuring a carrier part with a detachable bearing part that allows for easy mounting and retrofitting of electronic components, such as current transformers and sensors, without requiring disassembly of the lower part, enabling front-side plugging and separate handling of cabling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic components are integrated into the lower part of the switching device, then the device structure is compact and stable, but the device cannot be easily retrofitted with electronic components and requires disassembly of weight-intensive components
Solution Approach 1:
The device is divided into a lower part (carrying case) and an upper part (bearing part). The bearing part can be detached from the lower part, allowing electronic components to be mounted on the bearing part separately. This segmentation enables the bearing part to be removed and handled independently for retrofitting purposes, while the lower part remains stable and fixed.
Solution Approach 2:
The bearing part containing the electronic components is extracted as a separate, detachable unit from the lower part. This allows the electronic components to be mounted on the bearing part independently, which can then be attached to or removed from the lower part without disassembling weight-intensive components of the lower part itself.
2Ease of operation
If the bearing part is detachable and can be plugged from the front side, then retrofitting is simplified and independent handling is enabled, but the device complexity increases
Solution Approach 1:
The bearing part integrates multiple functions: it holds the electronic components, provides a front-side plugging interface, and connects to the lower part through a standardized interface. By merging these functions into a single detachable unit, the overall device complexity is managed while enabling easy retrofitting operations.
3Reliability
If weight-intensive components are housed in the lower part, then the device structure is stable, but accessing these components for retrofitting becomes difficult in confined spaces
Solution Approach 1:
The device is segmented into a lower part containing weight-intensive components and an upper bearing part containing electronic components. The bearing part is designed to be detachable, allowing it to be removed and handled independently in confined spaces without moving the heavy lower part, thus improving accessibility while maintaining structural stability.
Solution Approach 2:
The bearing part with electronic components is extracted as a separate, lightweight unit that can be easily removed from the lower part. This extraction allows technicians to work with the bearing part in confined spaces without the burden of handling weight-intensive components of the lower part.
