Floor Cleaning Head and Suction Foot Single-Drive Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning machines require separate drives and complex mechanisms for height-adjusting the cleaning head and suction foot, leading to increased costs and installation space needs.
Innovation Solution
A floor cleaning machine with a single, movable adjustment element coupled to both the cleaning head and suction foot, allowing for at least three positions: lifting both off the floor, suctioning fluid without contact, and simultaneous cleaning and suction, using a single drive mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate drives are used for cleaning head and suction foot adjustment, then reliable height adjustment is achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines two separate lifting functions (cleaning head and suction foot) into a single lifting device with one drive mechanism. The adjustment element is mechanically coupled to both the cleaning head and suction foot, allowing one drive to control both height adjustments simultaneously, thereby reducing device complexity while maintaining reliable adjustment capability
Solution Approach 2:
The single lifting device and adjustment element serve multiple functions: they can lift both the cleaning head and suction foot together, or selectively position one while keeping the other lowered. This multi-functionality eliminates the need for separate dedicated drives for each component, reducing overall system complexity
2Adaptability or versatility
If separate drives are used for cleaning head and suction foot adjustment, then independent position control is achieved, but installation space requirements increase
Solution Approach 1:
By merging the two lifting functions into one lifting device with a single drive, the installation space required is significantly reduced compared to having two separate drives. The compact single-drive mechanism occupies less space on the machine frame while still providing both cleaning head and suction foot adjustment capabilities
Solution Approach 2:
The adjustment element provides dynamic and flexible position control through its mechanical coupling to both the cleaning head and suction foot. By positioning the adjustment element at strategic locations and using linkages of appropriate lengths, the system can achieve various position combinations (both raised, one raised one lowered, both lowered) within a compact space

AI summary
A floor cleaning machine having a movable adjustment element, a suction foot, a cleaning head and a drive. The adjustment element is coupled to the cleaning head, the suction foot and the drive. The drive is configured to move the adjustment element between a first position, in which the cleaning head and suction foot are raised, a second position, in which the cleaning head is raised and the suction foot is lowered, and a third position in which the cleaning head and suction foot are lowered.
