Carpet Brush Dosing Roller for Uniform Care Product Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carpet care products are applied unevenly due to manual application, leading to inconsistent treatment, with some areas receiving excessive product while others receive none, resulting in inadequate carpet care.
Innovation Solution
A care product dosing unit integrated into a carpet brush device, featuring a dosing container, a rotatable dosing roller, and a drive unit, which forms a metering gap with the outlet gap to ensure uniform application, allowing for adjustable gap width and precise dosing through the metering roller's movement and rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual application of care product is used, then application flexibility is maintained, but application uniformity deteriorates
Solution Approach 1:
The dosing roller automatically meters and distributes the care product as it rotates, eliminating the need for manual control by the operator. The system self-regulates the application amount through the metering gap between the roller and outlet gap, ensuring uniform distribution while maintaining operational simplicity.
Solution Approach 2:
The metering gap distance between the dosing roller and outlet gap is adjusted to control the amount of care product applied. By changing this geometric parameter, the system achieves precise and uniform dosing while maintaining ease of operation through mechanical adjustment rather than manual application variability.
2Productivity
If larger outlet opening is used, then application speed increases, but dosing precision deteriorates
Solution Approach 1:
The dosing roller acts as an intermediary between the outlet gap and the carpet. It receives care product from the outlet gap and meters it through the controlled metering gap, thereby maintaining high application speed through the open outlet while achieving precise dosing through the restricted metering gap.
Solution Approach 2:
The outlet gap and metering gap are separated into two distinct functional zones. The outlet gap provides a large opening for rapid product flow, while the metering gap provides precise dosing control. This segmentation allows both high productivity and high precision to coexist in different stages of the application process.
3Manufacturing precision
If fixed metering gap is used, then dosing consistency is improved, but adaptability to different products deteriorates
Solution Approach 1:
The dosing roller is mounted on a movable guide rail that allows it to be displaced along the outlet gap. This dynamic positioning capability enables the metering gap to be adjusted for different care product types and dosing requirements, while maintaining dosing consistency through the controlled gap geometry for each specific application.

AI summary
The invention relates to a care product dosing unit (2) for arrangement in a carpet brush device, with a dosing container (4) for receiving a care product (18) for a carpet, a dosing roller (6) and a drive unit (8) for the dosing roller (4), wherein the dosing container (4) has an outlet gap (10) for the outlet of the care product (18) and the metering roller can be rotated about its longitudinal axis by means of the drive unit (8) and is arranged with its longitudinal axis parallel to the outlet gap (10) in such a way that it is attached to the outlet gap (10) so that a metering gap (12) is formed between the metering roller (6) and an edge of the outlet gap (10), through which care product (18) can be removed from the metering container (4) by rotating the metering roller (6). can be conveyed and/or metered. In this way, a care product dosing unit (2) is provided with which care product can be applied in doses to a carpet to be cared for in a simple and reliable manner.
