Maintenance Base Station
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintenance base stations have a complex structure due to the design of pivoting and locking portions, leading to a thickened bin body and excess overall design, as the pivot shaft and locking portion occupy necessary installation space, requiring a double-layer bin wall design.
Innovation Solution
A maintenance base station with a bin body and rotatable cover connected via a revolving shaft, where the bin wall adjacent to the opening is stretched to form an avoidance area, allowing the revolving shaft to be positioned outside the bin wall thickness, thereby avoiding interference and enabling independent optimization of the shaft and bin wall thickness designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pivot shaft and locking portion are accommodated within the bin wall, then the structural components can be integrated into the bin body, but the bin wall thickness increases and the overall design becomes excessive
Solution Approach 1:
The patent positions the pivot shaft outside the bin wall thickness direction, using the space lateral to the bin wall rather than within it. This dimensional repositioning allows the pivot shaft to be accommodated without increasing bin wall thickness, resolving the contradiction between structural integration and wall thickness.
Solution Approach 2:
The locking portion is nested within the pivot shaft structure, where the locking portion is accommodated inside or along the pivot shaft. This nesting arrangement allows both components to share the same external footprint without increasing bin wall thickness or overall device size.
2Shape
If the pivot shaft is positioned within the bin wall thickness, then the bin wall can maintain uniform thickness, but the revolving shaft interferes with the bin wall design and requires thickening
Solution Approach 1:
The patent repositions the pivot shaft from the wall thickness dimension to the lateral dimension, outside the bin wall. This allows the bin wall to maintain its optimal uniform thickness for structural integrity while the pivot shaft operates in a separate dimensional space, enabling independent optimization of both the bin wall and pivot shaft designs.

AI summary
Provided is a maintenance base station, including a bin body, a rotatable cover, and a revolving shaft, wherein the rotatable cover is in rotatable connection with the bin body via the revolving shaft, the bin body has a debris collection chamber and a opening in communication with the debris collection chamber, the rotatable cover is configured for blocking or revealing the opening; and partial bin wall of the bin body adjacent to the opening is stretched towards the inner side or the outer side of the bin body, hereby forming an avoidance area, and the revolving shaft is arranged in the avoidance area, such that the revolving shaft and the bin wall are spaced apart from each other along the wall thickness direction of the bin wall, so as to accordingly limit the intervention of the revolving shaft in the wall thickness of the bin wall.
