Dual fluid system for floor maintenance machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current floor cleaning machines face challenges in combining soap-based and ozone-generation systems without compromising their separate functionalities or requiring precise operator usage, as incorrect mixing of cleaning agents can damage equipment or reduce effectiveness.
Innovation Solution
A dual fluid supply system for floor cleaning machines that integrates both soap-based and oxygen-based systems, allowing for independent operation and compatibility, with soap or detergent introduced through a dedicated well and ozone generated externally, ensuring compatibility and reducing operator error risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If soap or detergent is added to the clean water tank for chemical cleaning, then cleaning effectiveness on oily surfaces is improved, but the ozone generation system may be damaged or rendered ineffective
Solution Approach 1:
The fluid supply system is divided into separate channels: a first fluid line dedicated to the ozone generation system and a second fluid line for the soap/detergent system. This segmentation prevents soap from reaching the ozone generator while allowing both cleaning methods to operate independently and effectively.
Solution Approach 2:
The soap injection mechanism is extracted from the main water tank system and placed in a separate soap well with its own dedicated fluid line. This extraction ensures that soap cannot accidentally enter the ozone generation system while maintaining the ability to use soap for chemical cleaning when needed.
2Device complexity
If a single fluid system is used for both soap-based and ozone-based cleaning, then device complexity is reduced, but functionality and effectiveness are compromised
Solution Approach 1:
The fluid supply system uses separate fluid lines for ozone-based cleaning and soap-based cleaning, allowing both systems to coexist without interference. This segmentation maintains full functionality of both cleaning modes while providing clear operational distinction.
Solution Approach 2:
The brush deck is designed with outlets that can receive both ozone-containing water and soapy water through separate fluid lines. This multi-functionality allows the single brush deck to effectively perform both oxygen-based and chemical-based cleaning tasks.
3Reliability
If operators are required to precisely control cleaning agent mixing, then cleaning effectiveness is optimized, but ease of operation is reduced
Solution Approach 1:
The soap injection mechanism is extracted and placed in a dedicated soap well with automatic injection capability. This eliminates the need for operators to manually measure and mix soap, preventing improper mixing while maintaining effective chemical cleaning when the soap system is activated.
Solution Approach 2:
The system provides self-service through automatic soap injection from the soap well and automatic ozone generation control. The machine manages the cleaning agent delivery itself, reducing reliance on operator skill and preventing human error in mixing or dosing.

AI summary
A floor maintenance machine includes a clean water tank and a brush deck. A first and second fluid supply system place the clean water tank in fluid communication with outlet(s) at the brush deck. The first fluid supply system includes a first fluid supply line adapted to receive a soap or detergent therein supplied from a soap or detergent well. The second fluid supply system includes an ozone generator and a second fluid supply line adapted to receive injected ozone therein with the ozone being generated from the ozone generator.
