Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional floor cleaning machines lack the ability to precisely control detergent solution concentration, leading to inadequate cleaning or excessive foaming, as the concentration is fixed and dependent on the ratio of detergent to water, without considering the type of soil, surface, or mechanical action.
Innovation Solution
A floor cleaning machine with a solid chemical delivery system that includes a pre-canister sensor to measure the baseline concentration of dissolved solids, a canister assembly to dissolve solid chemicals into the solution, and a post-canister sensor to adjust the concentration, ensuring optimal cleaning solution delivery to the cleaning head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional fixed concentration detergent solution is used, then the system is simple to operate, but the cleaning precision and adaptability to different floor conditions are insufficient
Solution Approach 1:
The system changes the concentration parameter of the detergent solution dynamically by dissolving solid chemical forms into the liquid solution at controlled rates. Sensors measure the concentration and feed back to the control system, which adjusts the dissolution rate to maintain optimal concentration levels adapted to different cleaning conditions.
Solution Approach 2:
The system incorporates sensors that continuously measure the detergent concentration in the solution and provide feedback to the control system. Based on this feedback, the control system adjusts the rate at which solid chemicals are dissolved into the solution, ensuring precise concentration control and enabling adaptation to varying floor conditions.
2Reliability
If more solid chemical form is dissolved into the solution, then the cleaning effectiveness improves, but excessive foaming and residue may occur
Solution Approach 1:
Sensors monitor the concentration of dissolved solids in the detergent solution and provide real-time feedback to the control system. When the concentration approaches optimal levels, the system automatically reduces or stops the dissolution of additional solid chemicals, preventing excessive foaming and residue while maintaining effective cleaning concentration.
Solution Approach 2:
The system uses automated sensor-based control to regulate the chemical dissolution process, eliminating the need for manual intervention. The sensors detect when optimal concentration is reached and the control system self-adjusts to maintain it, ensuring consistent cleaning effectiveness without over-concentration that would cause foaming or residue.
3Adaptability or versatility
If the detergent solution concentration is adjusted frequently, then the adaptability to different cleaning conditions improves, but the system complexity and operational difficulty increase
Solution Approach 1:
The system performs automatic concentration adjustment through integrated sensors and control mechanisms. The sensors detect the current concentration and the control system automatically regulates the dissolution of solid chemicals to achieve and maintain optimal levels, eliminating the need for manual adjustment and simplifying operation while providing full adaptability to different cleaning conditions.
Solution Approach 2:
The automated feedback loop continuously monitors detergent concentration and adjusts the chemical dissolution rate accordingly. This self-regulating system adapts to varying floor conditions and cleaning requirements without requiring operator intervention, maintaining optimal performance while keeping the interface simple and easy to operate.

This system allows for precise control of detergent concentration, optimizing cleaning efficiency by adjusting the chemical formulation based on real-time measurements, reducing waste and residue, and enhancing cleaning performance across varying floor conditions.
Implementation Method 1
A pre-canister sensor is configured to receive the cleaning solution from the solution tank and further configured to measure the concentration of any dissolved solids within the cleaning solution, thereby creating a baseline measurement.
Implementation Method 2
A canister assembly is configured to receive a portion of the cleaning solution from the pre-canister sensor and further configured to dissolve portions of a solid chemical form into the portion of the cleaning solution thereby forming blended droplets.
Implementation Method 3
A post-canister sensor is configured to receive a mixture of a portion of the cleaning solution from the pre-canister sensor and the blended droplets from the canister assembly. The post-canister sensor is configured to measure the concentration of any dissolved solids within the mixture.

AI summary
A floor cleaning machine is provided. The floor cleaning machine includes a solution tank for a cleaning solution. A pre-canister sensor receives the cleaning solution and measures the concentration of any dissolved solids. A canister assembly receives a portion of the cleaning solution from the pre-canister sensor and dissolves portions of a solid chemical form into the cleaning solution thereby forming blended droplets. The canister assembly has a spray nozzle positioned vertically above the solid chemical form. A post-canister sensor receives a mixture of the cleaning solution from the pre-canister sensor and the blended droplets from the canister assembly. The post-canister sensor measures the concentration of any dissolved solids within the mixture of the cleaning solution from the pre-canister sensor and the blended droplets from the canister assembly. A comparison of the baseline and post-canister measurements outside of a desired range results in replacement of the solid chemical form.
