A cleaning machine for cleaning surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning machines for large surfaces, such as floors, require manual inclination and lifting of the cleaning organ during transport, making it cumbersome to move while maintaining the cleaning organ raised and the frame stable.
Innovation Solution
Incorporation of auxiliary rest means, including a small pirouetting wheel and a stem with a groove system, allows the frame to transition between a maneuvering configuration with the cleaning organ raised and a cleaning configuration with the organ in contact with the floor, enabling stable movement and easy transfer by allowing the frame to rest on the auxiliary wheel when lowered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cleaning organ is raised during transfer, then the cleaning organ is positioned at a distance from the ground for easier movement, but the frame must be manually inclined and kept in that position, increasing operational complexity
Solution Approach 1:
The auxiliary wheel system enables the frame to automatically maintain its inclined position during transfer without requiring manual control. When the cleaning organ is raised, the frame naturally inclines and the auxiliary wheel contacts the ground to support the frame, creating a self-stabilizing mechanism that eliminates the need for continuous manual inclination control.
2Device complexity
If the cleaning machine uses only rear wheels for support, then the structure is simple, but the frame cannot maintain a stable inclined position during transfer, reducing transfer stability
Solution Approach 1:
The wheel support system is segmented into two functional parts: rear wheels for stationary support during cleaning operations and auxiliary wheels for support during transfer operations. This segmentation allows each wheel type to be optimized for its specific function, with the auxiliary wheels providing stable support during transfer when the frame is inclined, while the rear wheels provide stable support during cleaning when the frame is level.
