Disc Cleaner Particle Collection Ahead of the Squeegee
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wet cleaning devices often leave solid particles in front of or below the squeegee arrangement, which impairs the suction effect, leading to unsatisfactory cleaning results with streaks and smearing, due to the inability to effectively collect and manage these particles during the cleaning process.
Innovation Solution
A collecting device is placed between the soil working tool and the squeegee arrangement to catch and collect solid particles, utilizing a collecting container or receiving element like a sponge or fibers, which can be designed to extend laterally or vertically to ensure efficient particle collection and prevent them from reaching the squeegee.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the squeegee arrangement is used to suck liquid from the floor surface, then liquid removal is achieved, but solid particles accumulate in front of and below the squeegee arrangement, impairing the suction effect
Solution Approach 1:
The invention extracts the harmful solid particles from the system by introducing a collecting device that separates particles from the liquid flow path. The collecting device captures solid particles transported by the soil cultivation tool before they can reach and interfere with the squeegee arrangement, allowing the squeegee to focus solely on liquid removal without particle interference.
Solution Approach 2:
The collecting device acts as an intermediary element between the soil cultivation tool and the squeegee arrangement. It receives solid particles from the soil cultivation tool and prevents them from reaching the squeegee, thereby mediating the interaction between these two components and eliminating the harmful effect of particles on suction performance.
2Manufacturing precision
If the soil cultivation tool transports solid particles to the rear, then soil surface processing is achieved, but particles are deposited in the squeegee arrangement area, causing streaks and smearing
Solution Approach 1:
The invention converts the harmful effect of particle transport into a beneficial outcome by using the same soil cultivation tool that transports particles also to feed particles into the collecting device. The particle transport function, which originally caused harm, is redirected to serve the particle collection function, transforming the harmful particle flow into a useful feed source for the collecting device.
Solution Approach 2:
The collecting device extracts solid particles from the transport path before they can be deposited in the squeegee arrangement area. By removing particles from the system at the collection point, the invention prevents the harmful deposition effect that causes streaks and smearing on the floor surface.
3Reliability
If a collecting device is added to catch solid particles, then particle collection is improved, but device complexity increases
Solution Approach 1:
The collecting device is merged with the existing soil cultivation tool and squeegee arrangement into an integrated cleaning system. The collecting device shares space and structural elements with adjacent components, combining multiple functions (soil cultivation, particle collection, and liquid suction) into a unified device rather than adding a completely separate system.
Solution Approach 2:
The soil cultivation tool serves multiple functions: it processes the soil surface, transports solid particles to the rear, and simultaneously feeds particles into the collecting device. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in overall device complexity while maintaining effective particle collection.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances the cleaning effectiveness by preventing solid particles from interfering with the suction process, ensuring better liquid removal and maintaining a clean surface without streaks, thus providing improved cleaning results.
Implementation Method 1
