Solution Overview
Problem
Existing floor scrubbers fail to effectively clean the inner surface of the roller brush cover during the self-cleaning process, leading to poor user experience and manual cleaning requirements.
Innovation Solution
A cleaning device with a roller brush cover that can move between two positions relative to the floor brush housing, allowing for contact with the roller brush to clean the inner wall of the cover, utilizing a guide mechanism and liquid outlet assembly to facilitate self-cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the roller brush cover is kept stationary during self-cleaning, then the structure is simple and easy to manufacture, but the inner surface of the roller brush cover cannot be cleaned automatically
Solution Approach 1:
The roller brush cover is designed to move between a first position (during normal operation) and a second position (during self-cleaning) along an arc-shaped trajectory. This dynamic positioning enables the cover to contact the roller brush for cleaning purposes, achieving automatic cleaning functionality without requiring complex additional mechanisms.
Solution Approach 2:
The system utilizes the roller brush's own rotation to clean the inner surface of the roller brush cover. During self-cleaning mode, the roller brush rotates while the cover is positioned to contact it, allowing the brush to clean itself and the cover simultaneously, eliminating the need for separate cleaning mechanisms.
2Reliability
If the roller brush cover contacts the roller brush during operation, then cleaning effectiveness is improved, but friction and energy loss increase
Solution Approach 1:
The roller brush cover dynamically adjusts its position based on operational mode. During normal cleaning operation, the cover is in the first position with minimal contact to reduce friction. During self-cleaning mode, it transitions to the second position to maximize contact and cleaning effectiveness, optimizing performance for each specific function.
Solution Approach 2:
The system alternates between different operational states: normal cleaning mode with minimal contact and self-cleaning mode with increased contact. This periodic switching between states allows the system to achieve thorough cleaning when needed while minimizing energy loss during primary operation.

Function Achieved in This Case
Automates the cleaning of the roller brush cover, eliminating the need for manual cleaning and improving user experience by ensuring the inner surface is kept clean during the self-cleaning process.
Implementation Method 1
the roller brush cover and the floor brush housing enclose a roller brush cavity for fitting with the roller brush, and the roller brush cover is configured to be operable in a first position or a second position relative to the floor brush housing; in the first position, there is a first contact area between the roller brush cover and the roller brush; in the second position, there is a second contact area between the roller brush cover and the roller brush
