Solution Overview
Problem
Existing surface cleaning devices face challenges in effectively cleaning and maintaining the roller brushes due to wear and contamination, which affects their cleaning efficiency over time.
Innovation Solution
A brush head design featuring a pivotally connected waterway plate assembly with a scraper that abuts against the roller brush, ensuring continuous contact and cleaning even with wear, combined with a double-brush structure for enhanced cleaning efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed scraper is used to clean the roller brush, then the structure is simple, but the cleaning effectiveness deteriorates due to wear and contamination
Solution Approach 1:
The scraper is designed to be movable relative to the roller brush, allowing it to dynamically adjust its position and maintain contact pressure. The waterway plate assembly can pivot or move to accommodate roller brush wear, ensuring the scraper continuously abuts against the roller brush surface for effective cleaning throughout the roller brush's service life.
Solution Approach 2:
The system uses the roller brush's own rotation during normal operation to enable the scraper to clean its surface. The rotating roller brush passes repeatedly under the scraper, allowing continuous self-cleaning without additional mechanical driving mechanisms for the scraper itself.
2Reliability
If the scraper is made movable to maintain contact with the roller brush, then cleaning effectiveness is improved, but device complexity increases
Solution Approach 1:
The waterway plate assembly serves dual functions: it distributes cleaning liquid to the roller brush and supports the scraper mechanism. By integrating these functions into a single assembly that can pivot or move, the design achieves scraper mobility without adding separate complex mechanisms, thereby reducing overall device complexity while maintaining continuous cleaning contact.
3Device complexity
If a single brush structure is used, then the device is simple, but cleaning efficiency is limited
Solution Approach 1:
The cleaning system is divided into multiple functional segments: the roller brush for primary surface cleaning, the scraper for removing embedded contaminants, and the waterway plate for liquid distribution. This segmentation of cleaning functions into distinct components working in sequence enhances overall cleaning efficiency while maintaining reasonable structural simplicity through modular design.
