Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current floor cleaning devices face issues such as water spills during motor maintenance, heat dissipation problems, complex and unstable plastic structures, ineffective water removal leading to water stains, and high resistance in roller brushes, resulting in inefficient cleaning and damage to components.
Innovation Solution
A modularized mopping apparatus with a water-absorbent roller brush, threaded conveying rod, and sewage holding groove, along with a pressure roller assembly and adjustable mechanisms, which facilitates efficient water and dirt removal, reduces resistance, and allows for easy maintenance and assembly, while incorporating a heat dissipation channel to prevent motor damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a built-in drive motor is integrated into the roller brush, then the cleaning device achieves self-propulsion and improved cleaning efficiency, but water spills during motor replacement or maintenance can damage the motor and the structure becomes more complex
Solution Approach 1:
The roller brush assembly is divided into separable modules: the roller brush itself and the built-in drive motor. This allows the motor to be integrated for improved cleaning efficiency while enabling easy separation for maintenance, preventing water damage risks and simplifying repairs without compromising the integrated design benefits.
2Productivity
If the roller brush rotates at high speed to improve cleaning efficiency, then more dirt is removed, but heat dissipation becomes problematic and the motor is prone to damage by high temperature
Solution Approach 1:
A heat dissipation channel is introduced as an intermediary structure between the motor and the external environment. This channel facilitates thermal energy transfer from the motor to the surrounding air, enabling the motor to operate at high speeds for improved cleaning efficiency while maintaining safe operating temperatures through passive thermal management.
3Adaptability or versatility
If plastic parts are assembled to create complex structures, then the desired functionality is achieved, but the assembled structure becomes unstable and is easily damaged
Solution Approach 1:
Multiple plastic parts are merged into an integrated roller brush assembly that combines the roller brush, drive motor, and structural components into a unified module. This merging maintains the desired functionality while improving structural stability by eliminating weak points at assembly interfaces and reducing the number of separate components that could fail.
4Productivity
If a scraper is used to remove water stains on the roller brush, then dry/wet sweeping and mopping functions are claimed, but the scraper and roller brush are easily damaged and high resistance is applied to the roller brush
Solution Approach 1:
The mechanical scraper system is replaced with a centrifugal water removal mechanism that utilizes the rotational motion of the roller brush itself. The centrifugal force generated during rotation naturally separates and ejects water from the roller brush surface, eliminating the need for a separate scraper that would apply high resistance and cause damage to both the scraper and roller brush.
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 a stable, efficient, and convenient cleaning process with reduced power loss and extended component lifespan, effectively removing water and dirt without leaving stains, and allowing for easy maintenance and cost-effective production.
Implementation Method 1
The threaded conveying rod is rotatable in the sewage holding groove. The sewage holding groove is provided with a sewage discharge port in a rotary pumping and conveying direction of the threaded conveying rod
Implementation Method 2
The roller brush is a water-absorbent roller brush
Implementation Method 3
The threaded conveying rod is arranged at one side of the roller brush, and the threaded conveying rod is in contact with the roller brush. a gap is provided between a lower edge of the sewage holding groove opening and the roller brush, and the gap facilitates the roller brush to drive wastewater and/or particulate dirt into the threaded conveying rod by way of rotation

AI summary
A mopping apparatus and a cleaning device for floor cleaning are disclosed. The cleaning device comprises the mopping apparatus and a sewage tank (710). The sewage tank (710) collects water and/or dirt of the mopping apparatus. The mopping apparatus comprises a roller brush (1), a threaded conveying rod (21), and a sewage holding groove (62). The threaded conveying rod (21) is arranged at one side of the roller brush (1). The threaded conveying rod (21) is arranged in proximity to or attached to the roller brush (1). The threaded conveying rod (21) is rotatably mounted in the sewage holding groove (62). The threaded conveying rod (21) is arranged in proximity to or attached to an inner wall of the sewage holding groove (62). A sewage holding groove opening (622) is provided at one side of the sewage holding groove (62) facing the roller brush (1). Sewage on a surface of the roller brush (1) is squeezed and removed by the threaded conveying rod. This favors product miniaturization or diversified designs, provides an excellent sewage removal effect, has an ingenious design and a simple structure, and is simple to operate and convenient to use. The modularized design facilitates the assembly and the disassembly of the parts for replacement or maintenance. Sewage is conveyed from one end of the threaded conveying rod (21) to the other end. The protruding and recessed surface of the threaded conveying rod (21) kneads, pats, and squeezes the roller brush (1). A roller brush assembly is mounted and demounted in one piece.
