Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning equipment often has a small contact area with the surface to be cleaned, leading to low cleaning efficiency, and detachment of crawler mops is inconvenient.
Innovation Solution
A cleaning assembly with a mounting bracket, first and second driving rollers, and a pressure unit that allows for a large contact area and convenient attachment/detachment of the cleaning member, featuring a moving element and elastic elements to tension the cleaning member for improved contact with the surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single rolling brush or two rolling brushes are used, then the structure is simple, but the contact area with the surface is very small resulting in low cleaning efficiency
Solution Approach 1:
The cleaning assembly is divided into multiple independent driving rollers (first driving roller, second driving roller, third driving roller) that work in parallel. Each roller independently contacts the surface, collectively providing a large contact area while maintaining structural modularity and simplicity
Solution Approach 2:
The invention transitions from a single-point or linear contact approach to a distributed multi-point contact system by arranging driving rollers at different positions and orientations, effectively utilizing spatial dimensions to maximize surface contact area
2Productivity
If a crawler mop is used to increase contact time, then cleaning efficiency improves, but detachment becomes inconvenient and troublesome
Solution Approach 1:
The cleaning member is designed to be dynamically adjustable between a contracted state for easy attachment/detachment and an expanded state for effective cleaning. The expanding mechanism allows the cleaning member to extend outward from the housing to increase contact area during operation, then retract for convenient removal
Solution Approach 2:
The cleaning assembly incorporates self-retention features where the cleaning member automatically maintains its expanded position during cleaning operation through mechanical engagement, eliminating the need for continuous user intervention while remaining easily detachable when needed
3Productivity
If the cleaning member is tensioned to provide tight contact with the surface, then cleaning effect improves, but attachment and detachment becomes more difficult
Solution Approach 1:
The cleaning member transitions between contracted and expanded states, with tensioning mechanisms (such as elastic elements or spring-loaded components) that automatically apply appropriate tension when expanded, ensuring tight surface contact during cleaning while maintaining easy attachment/detachment in the contracted state
Solution Approach 2:
The housing includes pre-configured expansion mechanisms and guide structures that prepare the cleaning member for tensioning before contact with the surface, ensuring proper tension is applied automatically upon deployment without requiring manual adjustment or complex attachment procedures
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 solution provides enhanced cleaning efficiency by increasing the contact area and ensuring tight contact with the surface, while facilitating easy attachment and detachment of the cleaning member.
Implementation Method 1
an elastic element, two ends of the elastic element being respectively connected with the first driving roller and the second driving roller; the second driving roller is distant from the first driving roller under action of the elastic element
Implementation Method 2
a pressure unit disposed on the mounting bracket, the cleaning member including an active section for contacting with a surface to be cleaned, the pressure unit being in contact with an inner surface of the active section of the cleaning member

AI summary
The present disclosure discloses a cleaning assembly for surface cleaning, a surface cleaning device and a surface cleaning method. The cleaning assembly comprises a mounting bracket (5, 18), a first driving roller (11) and a second driving roller (32). The mounting bracket has a first surface and an opposite second surface, wherein a guide (41, 42) is disposed on the first surface and/or the second surface. A first driving roller is rotatably disposed between the first surface and the second surface of the mounting bracket. The second driving roller includes a moving element engaged with the guide, wherein the second driving roller moves away from or close to the first driving roller when the moving element of the second driving roller moves along the guide. A cleaning member (13) can be attached or detached conveniently when the second driving roller is close to the first driving roller. The cleaning member can be tensioned so as to perform a cleaning operation, when the second driving roller is distant from the first driving roller.
