Fuse Tube Cabin Guide Structure for Replaceable Fuse Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuse tube cabins are inflexible and inconvenient for replacing guiding elements and plum-blossom contact fingers, limiting their adaptability to different fuse sizes and plug-in sizes.
Innovation Solution
A fuse device with a removably mounted guiding element and contact fingers using threaded holes and screws, allowing for easy replacement and maintenance, enabling the fuse tube cabin to accommodate various fuse sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the guiding element and plum-blossom contact finger are fixedly mounted in the fuse tube cabin, then the structural stability is improved, but the ease of repair and adaptability to different fuse sizes deteriorates
Solution Approach 1:
The guiding element and plum-blossom contact finger are divided into separate, independently replaceable components. The guiding element is detachably mounted to the bottom electrode, and the plum-blossom contact finger is detachably mounted to the guiding element, allowing each component to be replaced individually without replacing the entire fuse tube cabin structure.
Solution Approach 2:
The mounting structure transitions from a fixed, static configuration to a dynamic, adjustable configuration. The detachable mounting mechanisms allow the guiding element and contact finger to be easily installed, removed, and replaced, providing flexibility for maintenance and adaptation to different fuse sizes while maintaining stable operation during use.
2Ease of manufacture
If the guiding element is cast in the fuse tube cabin, then the manufacturing simplicity is improved, but the adaptability to different fuse plug-in sizes deteriorates
Solution Approach 1:
The guiding element is separated from the fuse tube cabin structure and mounted detachably to the bottom electrode. This segmentation allows the guiding element to be manufactured independently and replaced or adjusted to accommodate different fuse plug-in sizes without modifying the entire fuse tube cabin.
Solution Approach 2:
The detachable mounting structure of the guiding element enables a single fuse tube cabin design to serve multiple functions by accommodating different fuse sizes through simple component replacement, rather than requiring different cabin designs for each fuse type.
