Solution Overview
Problem
Existing surface cleaning machines require suction fans to remove dirty fluid from cleaning rollers, which increases energy consumption and complexity, and users still come into contact with dirty fluid during operation.
Innovation Solution
A surface cleaning machine design that incorporates a scraper guide device to remove dirty fluid from cleaning rollers without suction fans, using a scraping effect to guide the fluid into a tank, allowing for energy-efficient operation and self-cleaning of the rollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a suction fan is used to remove dirty fluid from cleaning rollers, then dirty fluid removal effectiveness is improved, but energy consumption and device complexity increase
Solution Approach 1:
The suction fan is extracted/removed from the system. Instead of using active suction, the patent employs a scraper guide device that passively removes dirty fluid through scraping action, eliminating the need for energy-consuming suction components while maintaining cleaning effectiveness
Solution Approach 2:
The cleaning system performs self-service by using the scraper guide device to automatically remove dirty fluid from the cleaning rollers through mechanical scraping action. The dirty fluid is guided into the dirty fluid tank device without requiring external power sources, enabling the system to maintain itself without additional energy input
2Reliability
If a suction fan is used to remove dirty fluid from cleaning rollers, then dirty fluid removal effectiveness is improved, but device complexity increases
Solution Approach 1:
The suction fan and associated negative pressure lines are extracted from the system. The patent replaces this complex suction mechanism with a simple scraper guide device that directly scrapes dirty fluid from the rollers and guides it to the tank, significantly reducing device complexity
Solution Approach 2:
The scraper guide device provides self-service functionality by mechanically scraping and guiding dirty fluid without requiring complex control systems, sensors, or power distribution networks, thereby simplifying the overall device architecture
3Object-affected harmful factors
If a suction fan is used to remove dirty fluid from cleaning rollers, then user protection from dirty fluid is improved, but energy consumption and complexity increase
Solution Approach 1:
The suction fan is removed from the system. The scraper guide device provides adequate protection by containing and directing dirty fluid into the tank through passive mechanical action, eliminating the need for energy-consuming suction while still preventing user exposure
Solution Approach 2:
The system provides self-service protection by using the scraper guide device to automatically contain and redirect dirty fluid away from users during operation, maintaining safety without requiring additional energy input from suction fans
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 enables energy-saving operation without suction fans, reduces user exposure to dirty fluid, and achieves effective dirty fluid removal and self-cleaning of the cleaning rollers, enhancing the cleaning process efficiency and user safety.
Implementation Method 1
Dirty fluid is removed from the at least one cleaning roller unit by means of the scraper guide device, in particular, by virtue of a scraping effect
