Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface treatment machines face inefficiencies in cleaning effectiveness, energy efficiency, and maintenance due to vertical instability, inadequate cleaning of grout areas, and the use of unsuitable materials that fail to absorb and scrub effectively on various floor surfaces.
Innovation Solution
A surface treatment machine with a low drive assembly height to minimize vertical instability, a cleaning plate assembly that oscillates parallel to the floor surface, and a cleaning head with a hook or loop surface for detachable attachment, utilizing polypropylene microfiber or brush heads spaced to match grout spacing for improved cleaning of tile floors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the motor and drive assembly are positioned high above the cleaning plate, then the machine structure is simplified, but vertical instability increases causing unwanted oscillation and energy waste
Solution Approach 1:
The patent repositions the drive assembly from a vertical configuration (high above the cleaning plate) to a horizontal configuration (adjacent to the cleaning plate). This dimensional change in component layout maintains structural simplicity while eliminating vertical instability and unwanted oscillations by lowering the center of gravity and distributing mass more effectively.
2Device complexity
If a round bottom plate is used, then the machine structure is simpler, but cleaning effectiveness decreases at straight edges and corners
Solution Approach 1:
The cleaning plate is segmented into multiple functional zones: a rectangular front portion for effective cleaning along straight edges and in corners, and a rounded rear portion for structural integrity and maneuverability. This segmentation allows the plate to combine the cleaning effectiveness of a rectangular shape with the structural advantages of a rounded design.
3Device complexity
If brushes are used for cleaning, then the structure is simpler, but absorption of solid and liquid matter is insufficient
Solution Approach 1:
The cleaning head uses a composite structure combining polypropylene microfiber material with brush elements. The microfiber portion provides superior absorption of solid and liquid matter through its high surface area and capillary action, while the brush components provide mechanical scrubbing action. This composite approach delivers both absorption and mechanical cleaning functions that neither material could achieve alone.
4Quantity of substance
If cotton towels are used for cleaning, then absorption is improved, but friction with the floor surface increases reducing energy efficiency
Solution Approach 1:
The patent changes the material parameter from cotton to polypropylene microfiber. This material substitution maintains high absorption capacity through its engineered fiber structure and capillary properties while significantly reducing friction coefficients against floor surfaces. The result is improved energy efficiency during operation without sacrificing absorption performance.
