Solution Overview
Problem
Conventional extraction cleaners often face challenges in efficiently cleaning surfaces with heavy soiling due to the breakdown of cleaning solutions when using oxidizing agents, and they lack the ability to maintain effective pH levels for optimal cleaning performance.
Innovation Solution
The extraction cleaner employs a two-tank system with a basic cleaning solution and an acidic oxidizing solution, where the oxidizing solution is hydrogen peroxide-based, allowing for on-demand mixing to preserve stability and optimize cleaning effectiveness by maintaining a desired pH range, thereby enhancing cleaning performance on surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional extraction cleaners use oxidizing agents in cleaning solutions, then cleaning effectiveness on heavy soiling is improved, but the cleaning solution breaks down and pH levels become unoptimized
Solution Approach 1:
The cleaning system is divided into separate storage tanks: one for the base cleaning solution and another for the oxidizing agent (hydrogen peroxide). These components are stored separately to maintain stability, then combined in controlled proportions during operation to achieve effective cleaning without premature breakdown of the cleaning solution.
Solution Approach 2:
The system pre-mixes the base cleaning solution and oxidizing agent in optimal ratios before application to the surface. This preliminary mixing ensures the cleaning solution maintains effective pH levels and composition stability throughout the cleaning process, preventing breakdown that would occur if components were mixed in incorrect proportions or stored together.
2Productivity
If oxidizing agents are used to enhance cleaning performance, then staining and soil removal is improved, but the pH level becomes unoptimized reducing overall effectiveness
Solution Approach 1:
The system controls the concentration and pH parameters of the cleaning solution by precisely regulating the mixing ratio between the base cleaning solution and oxidizing agent. By adjusting these parameters through controlled dosing, the system maintains optimal pH levels (typically 10-12 for hydrogen peroxide-based solutions) that maximize both stain removal effectiveness and overall cleaning performance.
