Detachable Vacuum Cleaner Wheel Assembly for Tool-Free Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional intelligent vacuum cleaners have complicated mechanical connectors for wheel covers, requiring users to use hand tools to access the driving cavity, making it inconvenient to detach and clean the bottom side of the main casing.
Innovation Solution
A detachable wheel assembly arrangement with a detachable mechanism that allows the driving wheel to be selectively detached from the main casing without tools, featuring a rotating platform with a securing member and resilient element, and a wheel cover with an elastic locking member for easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If wheel cover is connected to main unit through complicated mechanical connectors (screws), then connection strength is improved, but ease of operation deteriorates (requires hand tools to detach)
Solution Approach 1:
The wheel assembly is segmented into detachable components: the wheel cover, the driving wheel assembly, and the main unit. The wheel cover can be detached from the main unit, and the driving wheel assembly can be removed from the wheel cover, allowing easy access to the driving cavity for cleaning without requiring tool-assisted disconnection of the entire wheel assembly.
Solution Approach 2:
The driving wheel assembly is extracted as a separate removable component from the wheel cover. This allows the driving wheel assembly to be taken out for cleaning the driving cavity while the wheel cover remains on the main unit, eliminating the need to detach the entire wheel assembly or use hand tools.
2Reliability
If complicated mechanical connectors are used for wheel cover, then reliability of connection is improved, but device complexity increases
Solution Approach 1:
The connection system is segmented into simple snap-fit interfaces between the wheel cover and main unit, and between the driving wheel assembly and wheel cover. This segmentation replaces complicated mechanical connectors with simple, tool-free snap-fit connections that are both reliable and easy to manufacture.
3Stability of the object's composition
If driving wheel assembly is permanently fixed in main unit, then structural stability is improved, but ease of repair deteriorates (difficult to access for cleaning)
Solution Approach 1:
The wheel assembly is segmented into detachable components that can be easily separated for cleaning and reassembled for stable operation. The wheel cover detaches from the main unit, and the driving wheel assembly detaches from the wheel cover, providing easy access to the driving cavity while maintaining structural stability during use.
Solution Approach 2:
The wheel assembly transitions from a static, permanently fixed structure to a dynamic, selectively detachable structure. The snap-fit connections allow the wheel cover and driving wheel assembly to be easily detached for cleaning and securely reattached for stable operation, adapting the structure to different operational needs.

AI summary
An intelligent vacuum cleaner includes a main casing, a vacuum cleaning arrangement, and at least one detachable wheel assembly arrangement. The main casing has a plurality of wheel compartments formed at a bottom side of the main casing. The vacuum cleaning arrangement is operatively provided in the main casing for generating a predetermined vacuum effect. The detachable wheel assembly arrangement is provided on the bottom side of the main casing, and includes at least one driving wheel and a detachable mechanism which is connected to the driving wheel and is detachably mounted in the main casing so that the diving wheel and the detachable mechanism are selectively detachable from the main casing for convenient cleaning of the bottom side of the main casing.
