Pull-Back Carpet Cleaner with Movable Suction Mouth Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current moquette carpet cleaning machines operable in pull-back mode require significant operator effort to manage the machine's weight and positioning, especially when transitioning to new cleaning strips, and lack the ability to perform pre-brushing without additional machinery.
Innovation Solution
Incorporation of an auxiliary wheel with movable support means that allows the machine to stabilize and raise the suction mouth, enabling easier forward movement and integration of a rotating brush for pre-brushing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the suction mouth is placed on the front part of the machine for pull-back operation, then the machine can effectively clean moquette carpets by spraying and suctioning, but the operator must raise and balance the machine on rear wheels when transitioning to new strips, increasing operator workload
Solution Approach 1:
The machine incorporates a movable front section that can be dynamically raised and lowered. The suction mouth is connected to the front section through a flexible conduit, allowing the front section to be raised for positioning without disconnecting the suction function. This dynamic adjustment enables easy transition between cleaning strips.
Solution Approach 2:
The machine is divided into a rear section (containing wheels and tank) and a movable front section (containing suction mouth). This segmentation allows the front section to be independently raised and positioned while the rear section remains stable, reducing operator effort during transitions.
2Adaptability or versatility
If the machine is designed for pull-back mode only, then it can effectively clean carpets, but it cannot perform pre-brushing without additional dedicated machinery
Solution Approach 1:
The machine integrates multiple functions into a single device: a rotating brush is incorporated that can perform pre-brushing before the suction mouth cleans the carpet. The brush can be activated independently or in conjunction with the suction system, allowing the machine to handle both pre-treatment and cleaning operations.
Solution Approach 2:
The pre-brushing function is merged with the cleaning function in the same machine. The rotating brush and suction mouth are positioned to work in sequence on the same carpet area, eliminating the need for separate pre-brushing equipment.
3Ease of operation
If the operator must sustain the machine weight on rear wheels during forward movement, then the machine can be repositioned, but the operator workload increases significantly
Solution Approach 1:
The machine incorporates a counterweight mechanism that balances the machine's weight distribution. The counterweight offsets the weight of the machine body and tank, reducing the force required by the operator to lift and reposition the machine onto the rear wheels.
Solution Approach 2:
The machine features a movable front section that can be raised and lowered dynamically. When repositioning is needed, the front section is raised to transfer weight to the rear wheels, and when cleaning, the front section is lowered to distribute weight and reduce operator effort.

AI summary
A moquette carpet cleaning machine (10) having a machine body (11) with main rear wheels (12) and a suction mouth (14) placed at the front of the machine body. A support (19) with an auxiliary wheel is attached to the machine body (11). At least one of the main wheels (12), the suction mouth (14), the auxiliary wheel (16) and the support (19) being movable with respect to the machine body (11) between at least a first position (A) and a second (B) position such that, the auxiliary wheel (16) is in the first position (A), the suction mouth (14) is maintained against the ground (20). When the auxiliary wheel is in the second relative position (B), the suction mouth (14) is maintained in a position that is substantially raised from the ground (20).
