Device for cleaning an object
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Objects with hollow zones, particularly those having a tubular portion open at one end, are difficult to clean due to the challenge of accessing and effectively cleaning the internal surfaces with conventional cleaning devices.
Innovation Solution
A cleaning device with a central zone of the second enclosure portion that extends inside the first enclosure portion to create a reception space around the object, allowing fluid to be directed into the tubular portion for improved cleaning efficiency and reduced fluid usage, featuring fluid feed and discharge ducts strategically positioned to optimize fluid flow and contact with the object's surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional cleaning enclosure is used without a central zone extension, then the device structure is simpler, but the cleaning effectiveness for objects with tubular portions is poor
Solution Approach 1:
The second enclosure portion extends its central zone inside the first enclosure portion, creating a nested configuration. This allows the cleaning device to access the interior of tubular objects while maintaining a compact overall structure, resolving the contradiction between cleaning effectiveness and device complexity.
Solution Approach 2:
The invention transitions from a conventional two-portion enclosure to a three-portion configuration by extending the central zone of the second enclosure portion into the first enclosure portion. This dimensional change creates additional cleaning pathways for fluid to reach tubular portions of objects, improving cleaning effectiveness without significantly increasing overall device complexity.
2Quantity of substance
If fluid is injected into a large enclosure space, then the enclosure can accommodate various objects, but the quantity of fluid required increases
Solution Approach 1:
The cleaning fluid is directed through the central zone extension to concentrate cleaning action at the tubular portions of objects where it is most needed. This localized fluid delivery reduces the total quantity of fluid required while maintaining the ability to clean various object types effectively.
Solution Approach 2:
The nested configuration of the enclosure portions creates a more compact fluid containment space that focuses fluid delivery where needed, reducing overall fluid consumption while maintaining versatility in accommodating different object geometries.
3Speed
If the space between the enclosure and the object is large, then the object can be easily inserted and extracted, but the fluid stream speed along the object wall decreases
Solution Approach 1:
The central zone extension creates a localized region with optimized spacing between the enclosure and the object's tubular portions. This localized configuration ensures high fluid stream speed where cleaning is most effective, while the overall enclosure design still allows easy object insertion and extraction.

AI summary
A cleaning device for cleaning an object having a peripheral edge defining a tubular portion of the object that is open at least one of its ends. The cleaning device has a cleaning enclosure, a first fluid feed duct for feeding fluid to the enclosure, and a first fluid discharge duct for discharging fluid from the enclosure. The cleaning enclosure has first and second enclosure portions. When the device is in its closed configuration at least one central zone of the second enclosure portion extends inside the first enclosure portion in order to define a reception space for receiving the object between the first enclosure portion and the central zone, which reception space extends all around the central portion.
