Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices struggle with simultaneous operation of vacuum and steam functions, leading to inefficiencies and messes due to moisture entering air flow conduits or dirt collectors.
Innovation Solution
A compact cleaning device with a surface interaction layer that supplies cleaning fluid and drains dirty fluid using underpressure, ensuring clean fluid is always used and reducing the need for frequent fluid replenishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cleaning fluid is stored in the surface interaction layer, then the device has fluid storage capacity, but the device becomes bulky and requires frequent dipping into buckets
Solution Approach 1:
The patent extracts the fluid storage function from the surface interaction layer itself, instead storing cleaning fluid in a separate reservoir and dirty fluid in a separate collection container. This allows the surface interaction layer to remain thin and compact while still providing adequate fluid supply and drainage capabilities through external storage systems.
2Device complexity
If cleaning fluid and dirty fluid are mixed, then the device structure is simpler, but cleaning effectiveness decreases due to increasing dirt concentration
Solution Approach 1:
The patent segments the fluid containment system into distinct compartments: a cleaning fluid reservoir, a surface interaction layer, and a dirty fluid collection container. This segmentation prevents mixing of clean and dirty fluids, maintaining cleaning effectiveness while managing system complexity through organized separation of functions.
Solution Approach 2:
The surface interaction layer acts as an intermediary between the cleaning fluid reservoir and the dirty fluid collection container. It receives clean fluid, performs the cleaning function, and transfers dirty fluid to the collection container, thereby preventing direct mixing of clean and dirty fluids while simplifying the overall fluid management system.
3Productivity
If vacuum and steam functions operate simultaneously, then cleaning productivity increases, but moisture enters air flow conduits causing mess and reduced effectiveness
Solution Approach 1:
The patent implements dynamic control of the surface interaction layer, adjusting its properties or position based on the operating mode (vacuum, steam, or combined). This dynamic adaptation allows the system to optimize performance for each function while preventing harmful moisture migration during simultaneous operation.

AI summary
A cleaning device comprises a surface interaction layer (ML), a cleaning fluid supply (CFF) provided with a cleaning fluid channel (CFC) at the surface interaction layer (ML) for supplying a cleaning fluid to a surface (F) through the surface interaction layer (ML) being in contact with the surface (F), and a dirty fluid drain (DFD) having a dirty fluid channel (DFC) at the surface interaction layer (ML) for draining, by means of underpressure, dirty water from the surface (F) through the surface interaction layer (ML) being in contact with the surface (F).
