Solution Overview
Problem
Existing cleaning systems require significant force to wring out cleaning fringes and are inefficient for cleaning large surfaces due to the need for long cleaning fringes that often contact the bucket wall during spin-drying, leading to reduced effectiveness and practicality.
Innovation Solution
A cleaning system with a compact bucket and basket design, where the basket can move upward and downward for washing out and rotate for spin-drying, maintaining a ratio of ≥1.5 between the basket's width and the carrier body's diameter to prevent contact with the bucket wall, allowing long cleaning fringes to be effectively washed and dried without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bucket diameter is increased to prevent cleaning fringes from contacting the bucket wall during spin-drying, then the spin-drying effectiveness is improved, but the bucket volume becomes excessively large and impractical to handle
Solution Approach 1:
The invention introduces a nested structure where a removable basket is placed inside the bucket. The basket has a diameter smaller than the bucket, creating an annular gap between them. During spin-drying, the cleaning fringes are contained within the basket, preventing contact with the bucket wall while maintaining compact bucket dimensions. This nested arrangement resolves the contradiction by providing sufficient clearance for effective spin-drying without requiring an oversized bucket.
2Productivity
If long cleaning fringes are used to clean large surfaces efficiently, then the cleaning productivity is improved, but the cleaning fringes contact the bucket wall during spin-drying, reducing spin-drying effectiveness
Solution Approach 1:
The basket nested within the bucket provides a contained space for the cleaning fringes during spin-drying. The basket's diameter is specifically designed to be larger than the carrier body diameter (ratio ≥1.5) to accommodate long cleaning fringes without wall contact, while the entire basket assembly fits within the bucket. This allows long fringes to be used for high productivity without compromising spin-drying effectiveness.
Solution Approach 2:
The basket acts as an intermediary structure between the cleaning fringes and the bucket wall. It provides a protective enclosure that prevents direct contact between the rotating cleaning fringes and the stationary bucket wall, eliminating friction and energy loss while allowing long fringes to maintain their cleaning effectiveness.
3Reliability
If the basket diameter is increased to accommodate long cleaning fringes, then the cleaning fringes can be spun dried effectively, but the basket and bucket dimensions become excessively large
Solution Approach 1:
The nested configuration allows the basket to have a diameter optimized for spin-drying effectiveness (≥1.5 times the carrier body diameter) while the bucket provides the outer containment. This separation of functions allows each component to be sized appropriately without requiring either the basket or bucket to be excessively large.
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
The system enables thorough washing and efficient spin-drying of long cleaning fringes within compact dimensions, allowing for rapid and effective cleaning of large surfaces with reduced effort, maintaining good handling properties.
Implementation Method 1
Due to the centrifugal forces, the cleaning fringes extend in a radial direction away from the carrier body and the stick in the direction of the boundary wall of the bucket.
Implementation Method 2
a washing-out device arranged in the bucket and configured to wash out the cleaning fringes, the washing-out device comprising a basket settable into an upward and downward movement

AI summary
A cleaning system includes: a bucket; a cleaning device with a mop head, the mop head including a carrier body and cleaning fringes that are fixed to the carrier body, the carrier body being connected to a stick on its side facing away from the cleaning fringes; and a washing-out device arranged in the bucket for washing out the cleaning fringes, the washing-out device including a basket settable into an upward and downward movement by a first actuating device, and a spinning device arranged in the bucket for spin-drying the cleaning fringes, the spinning device including the basket, which is settable into rotational movement by a second actuating device, and a centering pin, which is arranged in the basket and centers the cleaning device. The carrier body is essentially disk-shaped, with a circumferential boundary and with a maximum extension d1 between two circumferential areas opposite to each other.
