Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices for artificial turf are inefficient in dust removal and particle separation, leading to poor handling of dust and inadequate feedback of floor covering particles during the cleaning process.
Innovation Solution
A cleaning device with a dual negative-pressure chamber system, a cyclone filter, and a dual-screen separation device that uses a bypass duct to optimize suction and separation, allowing for effective dust removal and feedback of floor covering particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a suction device is used to remove dust particles during artificial turf cleaning, then dust removal is attempted, but the separating action is significantly affected and efficiency deteriorates
Solution Approach 1:
The cleaning device is divided into functionally independent modules: a sweeping device for gathering dirt, a separation device with screens for separating floor covering particles from dirt, and a filter device with suction for dust removal. This segmentation allows each module to perform its specific function without interfering with others, resolving the contradiction between dust removal and separation efficiency
Solution Approach 2:
The dust removal function is extracted as a separate subsystem with its own suction device and filter, independent from the separation device. The suction device draws air through the filter device separately, while the separation device focuses solely on separating floor covering particles from dirt through screening, eliminating the negative interaction between suction and separation
2Ease of operation
If floor covering particles are stirred up during cleaning, then dirt particles can be accessed, but floor covering particles need to be fed back onto the turf
Solution Approach 1:
A feedback device is implemented to return floor covering particles that are removed during cleaning back onto the artificial turf surface. The separation device collects floor covering particles on screens, and the feedback mechanism redistributes them uniformly across the turf, preventing particle loss and maintaining the turf's functional properties
Solution Approach 2:
Instead of discarding floor covering particles that are stirred up during cleaning, the system recovers them through the separation device's screening process and returns them to the turf via the feedback device, converting a potential loss into a recoverable resource

AI summary
A cleaning device for cleaning artificial floor coverings provided with floor covering particles, such as artificial turf, comprising a sweeping device for gathering dirt particles from the floor covering, a separation device for separating the dirt particles from floor covering particles, a floor covering particle feedback device for gathering the floor covering particles separated from the dirt particles and feeding back the floor covering particles to the floor, a filter device for filtering dust particles, and a suction device which draws air from the area of the separation device through the filter device. First and second negative-pressure chambers in which negative pressure can be formed by the suction device suction are formed above and below the separation device, respectively, in fluid communication through the separation device. The first negative-pressure chamber is in fluid communication with the suction device only via the second negative-pressure chamber.
