Solution Overview

Problem

Existing cleaning devices for artificial turf inefficiently remove dust and impair the separating effect due to inadequate suction, leading to suboptimal cleaning and particle return processes.

Innovation Solution

A cleaning device with a dual vacuum chamber system, a bypass channel, and a cyclone filter, where air is sucked through the separating device to create negative pressure zones, enhancing dust removal and supporting the separation process while allowing floor covering particles to be effectively returned.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a suction device is used to remove dust particles from artificial turf, then dust removal is intended to be improved, but the separating effect is significantly impaired and cleaning efficiency decreases

Engineering Contradiction:
Improvedust removalVSAvoidcleaning efficiency
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The suction process is segmented into two distinct vacuum chambers: a first vacuum chamber for dust removal above the separator, and a second vacuum chamber for supporting the separation process below the separator. This segmentation allows independent optimization of each suction function without mutual interference, resolving the contradiction between dust removal and separation efficiency

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bypass channel acts as an intermediary element connecting the first and second vacuum chambers. It allows controlled air flow between chambers while maintaining pressure differentials, enabling the suction device to perform both dust removal and separation support functions simultaneously without compromising either process

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If air is suctioned through the separating device, then dust particles can be removed, but floor covering particles may be lost and separation effectiveness decreases

Engineering Contradiction:
Improvedust particle removalVSAvoidfloor covering particle loss
Core Design Contradiction:
Object-affected harmful factorsVSLoss of substance

Solution Approach 1:

Different local qualities are created in different regions: the first vacuum chamber above the separator provides strong suction for dust removal, while the second vacuum chamber below the separator provides gentler suction to support separation without causing particle loss. The bypass channel controls the transition between these different local suction qualities

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The suction force is applied partially and selectively: excessive suction is applied in the first chamber for effective dust removal, while partial suction is applied in the second chamber to maintain separation effectiveness. This partial action approach prevents floor covering particle loss while still achieving thorough dust removal

Inventive Principle:
Principle #16Partial or excessive action

AI summary

The cleaning device (10) has a sweeping unit (12) for receiving dirt particles from the surface, and a separating unit (14) for separating the dirt particles of floor. A surface particle return unit (16) re-circulates the dirt particles to the ground. A filter unit filters the dust particles, and a suction unit (20) sucks the filtered dust particles from the filter unit. The vacuum chambers are fluid communicated through the separation unit, and are connected with the suction unit.
