Solution Overview
Problem
Existing cleaning devices face challenges in uniformly and thoroughly cleaning the cleaning cylinder, leading to reduced efficiency and potential secondary pollution, while collection bins suffer from air leakage and mixed waste management issues.
Innovation Solution
A cleaning apparatus with a housing, rolling brush, and cleaning assembly featuring evenly spaced cleaning medium spray orifices, a collection bin with a filtering plate for separating waste, and a sealing ring design to prevent air leakage.
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 water is not sprayed evenly resulting in excessive or insufficient local cleaning
Solution Approach 1:
The cleaning apparatus divides the single water spraying function into multiple independent spray nozzles arranged around the cleaning cylinder. Each nozzle sprays cleaning medium onto a specific segment of the cylinder surface, ensuring comprehensive and uniform coverage without the limitations of a single spraying point.
Solution Approach 2:
Different spray nozzles are positioned at different locations to provide localized cleaning for different sections of the cleaning cylinder. The cleaning medium is delivered to specific areas where it is most needed, achieving uniform cleaning across the entire surface rather than relying on a single general spraying action.
2Manufacturing precision
If the cleaning cylinder is detached for cleaning, then the cleaning cylinder can be cleaned thoroughly, but the detachment operation process is complicated and reduces service life
Solution Approach 1:
The cleaning apparatus enables the cleaning cylinder to clean itself automatically while remaining installed in the cleaning device. The spray nozzles are integrated into the housing and directed toward the cleaning cylinder surface, allowing the cylinder to be cleaned in situ without requiring detachment or manual intervention.
3Device complexity
If the cleaning cylinder is not cleaned regularly, then the device structure remains simple, but the surface to be cleaned is difficult to clean and secondary pollution occurs
Solution Approach 1:
The cleaning apparatus enables continuous cleaning operation by automatically cleaning the cleaning cylinder during or between ground cleaning operations. This ensures the cleaning cylinder surface remains clean and effective throughout its service life, maintaining high cleaning efficiency without requiring periodic shutdowns for manual maintenance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
