Switching Block Cover Insertion Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switching strip arrangements complicate the removal and insertion of the cover part from the carrier part, especially in poor lighting conditions, requiring multiple alignment points and significant effort.
Innovation Solution
The second counter-structure merges into the first counter-structure, allowing both the guide and bearing structures to be inserted at a single point, simplifying the process by eliminating the need for multiple alignment points and facilitating easier handling through a design where the cover part can be inserted or removed from the side, with a shift lever mechanism converting pivoting movements into lifting movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guide structure and bearing structure are inserted into separate counter-structures, then the structural guidance and movement conversion are achieved, but the insertion process becomes complicated requiring multiple alignment points and significant effort
Solution Approach 1:
The patent combines the guide structure and bearing structure into a single integrated counter-structure on the carrier part. This merging allows both structures to be inserted simultaneously at one location, eliminating the need for separate alignment operations and significantly simplifying the cover insertion process while maintaining reliable structural guidance and movement conversion functionality
2Manufacturing precision
If multiple alignment points are required for inserting the cover, then precise positioning is achieved, but the operation becomes time-consuming and difficult in poor lighting conditions
Solution Approach 1:
By integrating the guide structure and bearing structure into a single counter-structure, the patent reduces the number of alignment points from multiple separate locations to one unified insertion point. This maintains precise positioning capability while dramatically reducing the time and complexity of the alignment process, making the operation feasible even in poor lighting conditions
3Ease of operation
If the cover is designed to be removable from the carrier part, then easy access for fuse replacement is achieved, but the complexity of insertion and removal procedures increases
Solution Approach 1:
The patent integrates the guide and bearing structures into a single counter-structure, which simplifies the overall insertion mechanism. This integration reduces the number of components and assembly steps required, making the removable cover design easier to operate while maintaining easy access for fuse replacement
