Application of cleaning solution on a surface maintenance machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning machines struggle to efficiently vary the intensity of cleaning fluid application across different areas of the cleaning tool, leading to uneven cleaning and potential inefficiencies.
Innovation Solution
A surface maintenance machine with a cleaning fluid source that varies the intensity of cleaning fluid exiting the outlet nozzle to at least two different intensities, allowing for controlled fluid dispensing on corresponding areas of the tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If cleaning fluid is dispensed uniformly across the entire tool, then the device complexity is reduced, but the cleaning precision becomes uneven across different areas of the tool
Solution Approach 1:
The cleaning fluid dispensing system is segmented into multiple independent nozzle groups, each capable of being controlled separately. This allows different areas of the tool to receive cleaning fluid at different intensities, achieving uniform cleaning precision across the entire tool surface while maintaining manageable system complexity through modular design
Solution Approach 2:
The cleaning fluid dispensing system is made dynamic by enabling real-time adjustment of fluid intensity at different nozzle locations. The system can vary the intensity of cleaning fluid exiting different nozzles based on the specific cleaning requirements of different tool areas, achieving precise control over cleaning uniformity without requiring an overly complex static system
2Productivity
If cleaning fluid intensity is increased across the entire tool, then the productivity of cleaning is improved, but the loss of substance (cleaning fluid) increases
Solution Approach 1:
The system applies local quality by dispensing cleaning fluid at different intensities to different areas of the tool based on specific cleaning needs. High-intensity fluid application is directed only to areas requiring thorough cleaning, while other areas receive appropriate lower intensities, thereby maintaining high cleaning productivity while minimizing overall cleaning fluid consumption
Solution Approach 2:
The system dynamically changes the parameter of cleaning fluid intensity at different nozzle locations and times. By adjusting fluid intensity parameters locally and temporally, the system achieves high productivity where needed while reducing total fluid usage, optimizing the balance between cleaning effectiveness and resource consumption

AI summary
A surface maintenance machine comprises a surface maintenance head assembly with attached surface maintenance tool for collecting debris/fluid using a fluid delivery/recovery system. Embodiments include an outlet nozzle configured to dispense cleaning fluid exiting the outlet nozzle on the surface maintenance tool. The outlet nozzle is fluidly connected to a cleaning fluid source which can vary the intensity of cleaning fluid exiting the outlet nozzle such that different intensities of the cleaning fluid correspond to the cleaning fluid being dispensed on different areas of the surface maintenance tool. Embodiments also include a second outlet nozzle, located opposite the first, which is configured to dispense cleaning fluid exiting the outlet nozzle on the surface maintenance tool. Further embodiments include a pump which can vary the intensity of cleaning fluid exiting the outlet nozzle in a cyclical manner and suspend the cleaning fluid from exiting the outlet nozzle.
