Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cleaning device uses a single roller part for both cleaning and regeneration, then the device complexity is reduced, but the productivity decreases because the cleaning process must be interrupted for regeneration
Solution Approach 1:
The roller is divided into two distinct roller parts: a first roller part for cleaning the surface and a second roller part for regenerating the endless cleaning element. This segmentation allows both functions to occur simultaneously without interrupting the cleaning process, thereby maintaining productivity while managing device complexity through functional separation.
Solution Approach 2:
The invention introduces a dimensional distinction by using roller parts with different radii of curvature. The first roller part has a larger radius optimized for surface contact and cleaning, while the second roller part has a smaller radius optimized for centrifugal regeneration. This dimensional differentiation enables both cleaning and regeneration to occur concurrently on different dimensional planes of the same roller assembly.
2Reliability
If the cleaning device uses different radii of curvature for roller parts, then the regeneration effectiveness is improved through varying centrifugal forces, but the manufacturing precision requirements increase
Solution Approach 1:
Different regions of the roller assembly are assigned different radii of curvature tailored to their specific functions. The first roller part has a larger radius optimized for gentle surface cleaning, while the second roller part has a smaller radius optimized for high-speed centrifugal regeneration. This local quality differentiation improves regeneration effectiveness while the radii differences are designed to be practical for manufacturing.
3Reliability
If the cleaning device interrupts the cleaning process for regeneration, then the endless cleaning element can be effectively regenerated, but the loss of time increases
Solution Approach 1:
The invention enables continuous operation by performing regeneration and cleaning simultaneously through the dual roller part system. While the first roller part continues cleaning the surface, the second roller part concurrently regenerates the endless cleaning element using centrifugal force. This eliminates idle time and maintains continuous productive action throughout the operation cycle.
Solution Approach 2:
The regeneration function is prepared in advance through the pre-configured second roller part with smaller radius, which is always positioned to receive and regenerate the endless cleaning element as it circulates. This preliminary preparation of the regeneration mechanism ensures that regeneration can occur immediately and continuously without interrupting the cleaning process.
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
Enables continuous operation with simultaneous cleaning and regeneration, eliminating the need for additional motors and separate speed settings, effectively managing dirty liquid through varying centrifugal forces.
Implementation Method 1
the endless cleaning element is pulled into the area of this non-rotatable roller part by the roller part, thereby creating friction between the endless cleaning element and the roller part
Implementation Method 2
the different radii of curvature result in deviating centrifugal forces acting on the dirty liquid in the area of these radii of curvature

AI summary
The invention relates to a cleaning device, in particular a floor-cleaning device, comprising a cleaning unit which is at least partly covered by an endless cleaning element that can be rotated continuously in relation to a surface to be cleaned during the action upon a surface to be cleaned. In order to devise a cleaning device in which regeneration of the endless cleaning element is particularly comfortable, the cleaning unit comprises at least one first roller part which can be placed on the surface to be cleaned and a second roller part, the radius of curvature of a roller subsection of the first roller part being different from a radius of curvature of a roller subsection of the second roller part.
