Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mopping devices face inefficiencies in cleaning effectiveness and maintenance, with passive mopping being inadequate and active mopping requiring complex structures and high water consumption, while also risking sewage residue due to suction tray friction.
Innovation Solution
An integrated device with a sweeping structure and automatic mopping mechanism featuring rotatable wet and dry mopping rollers, a spray nozzle, and a wringing and cleaning system that allows for simultaneous wet and dry mopping without a suction tray, ensuring effective cleaning and roller maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If passive mopping is used with a fixedly installed rag, then the structure is simple to implement, but the cleaning effect is not good and the rag is easy to get dirty
Solution Approach 1:
The patent transforms the fixed rag installation into a dynamic system where the rag is mounted on a rotatable brush assembly that can actively rotate during operation. This dynamic rotation enables the rag to effectively contact and clean the floor surface, significantly improving cleaning performance while maintaining structural simplicity.
2Reliability
If active mopping is used with movable parts and rotating mechanisms, then the cleaning effect is better, but more driving parts are needed and the structure is more complicated
Solution Approach 1:
The patent combines the mopping function with the existing sweeping brush structure. The rag is integrated onto the rotating brush assembly, allowing the same motor that drives the brush to also drive the mopping action. This merging eliminates the need for separate driving mechanisms, reducing structural complexity while maintaining effective cleaning.
3Reliability
If water consumption is increased with a suction motor and suction tray to recover sewage, then the cleaning effect is good, but the structure is large and the suction tray is easy to damage and leak water
Solution Approach 1:
The patent extracts and eliminates the suction tray component from the system. Instead of using a suction motor and tray to recover sewage, the design relies on controlled water application followed by natural evaporation or absorption, removing the complex suction mechanism and its associated reliability issues.
4Loss of substance
If a suction tray is used to suck up residual sewage, then sewage can be collected, but friction between the suction tray and floor causes damage and water leakage
Solution Approach 1:
The patent converts the harmful friction contact of the suction tray with the floor into a beneficial passive process. By eliminating the suction tray, the system allows water to be applied and then naturally evaporate or be absorbed by the floor, turning a potentially damaging mechanical interaction into a harmless natural process while still achieving effective cleaning.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The integrated device achieves better cleaning efficiency by alternating wet and dry mopping rollers, reducing sewage residue and maintaining roller cleanliness, thus enhancing floor cleaning effectiveness and reducing maintenance needs.
Implementation Method 1
a spray nozzle spraying water on one of the wet mopping rollers mopping the floor and further spring water on a region of the floor
Implementation Method 2
one of the wet mopping rollers mopping the floor and one of the dry mopping rollers mopping the floor sequentially
