Solution Overview
Problem
Existing cleaning devices face issues with uneven cleaning of the cleaning cylinder, leading to secondary pollution and reduced efficiency, as well as challenges with solid-liquid waste separation, air leakage, water residue, and mold growth on rolling brushes.
Innovation Solution
Implementing a cleaning apparatus with equal-length flow channels for uniform cleaning medium distribution, a filtering plate for solid-liquid separation, a sealing ring design to prevent air leakage, and features to manage water and dirt residue, along with ventilation to prevent mold growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If water spraying apparatus is used to clean the cleaning cylinder, then the cleaning cylinder can be cleaned automatically, but the cleaning medium is sprayed unevenly resulting in excessive or insufficient local cleaning
Solution Approach 1:
The cleaning apparatus divides the single water spraying function into multiple independent spray orifices distributed across different spray bars. Each spray orifice targets a specific section of the cleaning cylinder, ensuring uniform coverage. The cleaning medium is delivered through multiple separate flow channels rather than a single channel, segmenting the delivery system to achieve even distribution.
Solution Approach 2:
Different sections of the cleaning cylinder receive cleaning medium through locally optimized spray orifices positioned at specific locations. Each spray orifice is designed to target its specific local area, ensuring that every part of the cleaning cylinder receives appropriate cleaning attention. The spray bars are positioned to create local cleaning zones that collectively cover the entire surface uniformly.
2Manufacturing precision
If the cleaning cylinder is detached for cleaning, then the cleaning cylinder can be cleaned thoroughly, but the detachment operation process becomes complicated and service life is reduced
Solution Approach 1:
The cleaning apparatus enables the cleaning cylinder to clean itself automatically while installed in the cleaning device. The spray orifices and spray bars are positioned to direct cleaning medium onto the cleaning cylinder surface without requiring removal. The system performs self-cleaning functionality, eliminating the need for manual detachment and reattachment operations.
Solution Approach 2:
The cleaning medium (water or cleaning solution) acts as an intermediary substance that transfers cleaning action to the cleaning cylinder surface. The spray bars and spray orifices serve as intermediary components that deliver the cleaning medium efficiently. This intermediary mechanism enables thorough cleaning without direct mechanical intervention or detachment.
3Device complexity
If the cleaning cylinder is not cleaned regularly, then the device structure remains simple, but the cleaning cylinder causes secondary pollution to the surface being cleaned
Solution Approach 1:
The cleaning apparatus enables continuous or periodic cleaning of the cleaning cylinder during normal operation. The spray system can be activated at regular intervals or continuously to maintain the cleaning cylinder surface. This continuous cleaning action prevents dirt accumulation and eliminates the source of secondary pollution without requiring complete disassembly or complex maintenance procedures.
