Rack-Mount Chassis Door Plate Detachable Pivot Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rack-mount chassis designs make it inconvenient to replace door plates, as they are directly pivoted onto the rear casing, limiting flexibility and maintenance options.
Innovation Solution
A detachable pivot assembly is introduced, comprising a first and second pivot assembly with bearing and shaft portions, allowing the door plate to be easily replaced by providing a mechanism for secure attachment and detachment along a pivot axis, with features such as limiting pieces and passages to ensure proper alignment and secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door plate is directly pivoted onto the rear casing of the chassis, then the structure is simple, but the door plate cannot be replaced conveniently
Solution Approach 1:
The pivot assembly is divided into separate components: a pivot hole formed on the rear casing, a pivot shaft with a shaft body and shaft limiting piece, and a pivot passage. This segmentation allows the door plate to be detached by removing the pivot shaft through the pivot passage, enabling convenient replacement while maintaining structural integrity during operation.
2Adaptability or versatility
If the door plate is directly pivoted onto the rear casing, then the structure is simple, but flexibility and maintenance options are limited
Solution Approach 1:
The pivot shaft acts as an intermediary component between the rear casing and the door plate. It includes a shaft body that fits into the pivot hole and a shaft limiting piece that prevents excessive movement. This intermediary structure enables easy attachment and detachment of different door plate types (transparent or opaque) while providing stable connection during use.
3Ease of manufacture
If the door plate is directly pivoted onto the rear casing, then manufacturing is simple, but replacement requires disassembly of the entire door plate
Solution Approach 1:
The pivot connection is segmented into a pivot hole in the rear casing, a removable pivot shaft with limiting piece, and a pivot passage. This allows the pivot shaft to be independently removed through the passage, enabling door plate replacement without complex disassembly while keeping the manufacturing process relatively simple through standard machining operations.

AI summary
A rack-mount chassis includes a rear casing, a door plate, a first pivot assembly, and a second pivot assembly. The rear casing has an opening. The door plate is configured to shield the opening. The first pivot assembly includes a first bearing portion and a first shaft portion. The first bearing portion has a first shaft hole and a first passage. The first passage extends from the first shaft hole to an outer edge of the first bearing portion. The first shaft portion has a first shaft body. The first shaft body is moved into the first shaft hole through the first passage. The second pivot assembly includes a second bearing portion and a second shaft portion. The second bearing portion has a second shaft hole. The second shaft portion has a second shaft body. The second shaft body is located in the second shaft hole.
