Bus Bar Module Cover Latch Vertical Offset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bus bar modules make it difficult for operators to easily open and close the output terminal cover due to the positioning of the latch section and cover latching claw, which are often obstructed by the case, hindering finger access and operation.
Innovation Solution
A bus bar module design featuring a hinge section at the base end of the output terminal installation section, with a cover latch section at the tip end, and a guide section to align the cover latch section with the cover latching section, allowing for easier access and operation by offsetting the cover latch section and using guide surfaces or recesses to facilitate alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the latch section and cover latching claw are positioned at the same height as the hinge section, then the structural compactness is improved, but the ease of operation deteriorates because the case blocks finger access to the latch section
Solution Approach 1:
The patent repositions the latch section and cover latching claw from the same height as the hinge section to a different vertical level. This dimensional relocation allows operators to access the latch section without their fingers being blocked by the case, thereby improving ease of operation while maintaining structural compactness through optimized spatial arrangement
2Volume of moving object
If the output terminal cover is positioned close to the case, then the device compactness is improved, but the ease of operation deteriorates due to limited access to the latch mechanism
Solution Approach 1:
The patent resolves the conflict between device compactness and operational accessibility by relocating the latch mechanism to a different vertical dimension. The latch section is positioned at a height different from the hinge section, creating a vertical offset that provides finger access clearance while maintaining the cover's close proximity to the case for compactness
3Ease of manufacture
If the latch section is positioned at the same level as the hinge section, then the manufacturing simplicity is improved, but the ease of operation worsens due to obstruction by the case
Solution Approach 1:
The patent maintains manufacturing simplicity by using standard positioning techniques while improving operational convenience through vertical repositioning of the latch section. The latch section is placed at a different height level from the hinge section, which requires minimal additional manufacturing complexity but significantly improves finger access and operation convenience
