Surface Cleaner ROS Generation for Organic Stain Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface cleaning devices, such as steam mops, are limited in their ability to effectively remove organic stains and odors due to the lack of reactive oxygen species generation, which are essential for oxidizing and breaking down unstable bond structures in soils and stains.
Innovation Solution
Integration of a reactive oxygen species generator within the surface cleaning apparatus, utilizing an ultrasound transducer and acoustic horn to cavitate water molecules and produce reactive oxygen species, which are then applied to the cleaning pad to enhance cleaning efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional steam-based cleaning is used, then the device structure is simple, but the ability to remove organic stains and odors is insufficient
Solution Approach 1:
The patent combines steam generation with reactive oxygen species generation in a single cleaning device. The steam generator and ROS generator are integrated into one system, allowing both steam and ROS to be applied simultaneously to the cleaning pad, thereby enhancing cleaning efficacy while maintaining reasonable device complexity
Solution Approach 2:
The patent introduces a new parameter (reactive oxygen species) to the cleaning process alongside the traditional steam parameter. This changes the chemical environment on the cleaning pad surface, enabling oxidation of organic stains and odors that steam alone cannot effectively remove
2Productivity
If reactive oxygen species generator is integrated, then cleaning efficacy is improved, but device complexity increases
Solution Approach 1:
The cleaning fluid serves multiple functions: it is heated to generate steam for thermal cleaning, and simultaneously undergoes ultrasonic cavitation to generate reactive oxygen species for chemical cleaning. This multi-functionality of the same fluid stream reduces the need for separate systems and minimizes device complexity
Solution Approach 2:
The cleaning fluid acts as an intermediary medium that carries both steam and reactive oxygen species to the cleaning pad. By using the fluid as a carrier for both cleaning mechanisms, the patent avoids needing separate delivery systems, thereby managing device complexity

AI summary
A surface cleaning apparatus includes a housing with an on-board reactive oxygen species generator which produces reactive oxygen species in situ from fluid stored within an on-board supply tank of the surface cleaning apparatus, and further delivers the generated reactive oxygen species to a cleaning pad attached to the housing of the surface cleaning apparatus.
