Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning systems using steam and textile microfiber sheets face issues such as inconvenient washing, trapped dirt, uneven wetting, inefficiency in cleaning greasy particulate soils, and streaks due to high surface tension water.
Innovation Solution
A cleaning system comprising a steam appliance with pre-wetted disposable pads containing a cleaning solution, where the pads have a laminate construction with a hydrophobic floor contacting layer and an absorbent storage layer, ensuring consistent wetting and effective stain removal without leaving streaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If textile microfiber floor sheets are used with steam appliances, then cleaning capability is improved, but maintenance convenience deteriorates due to inconvenient washing and trapped dirt
Solution Approach 1:
The patent employs disposable floor sheets made of cellulosic material that are discarded after a single use, eliminating the maintenance issues associated with reusable textile microfiber sheets. These disposable sheets prevent dirt trapping problems and washing inconvenience while maintaining effective cleaning capability through their single-use nature and chemical treatment.
Solution Approach 2:
The patent applies chemical treatments to the cellulosic floor sheets, including surfactants and other cleaning agents, to enhance their cleaning performance. This chemical parameter modification allows the disposable sheets to achieve cleaning effectiveness comparable to or better than reusable microfiber sheets, resolving the contradiction between cleaning capability and maintenance convenience.
2Reliability
If pre-wetted floor sheets are used, then cleaning of soluble stains is improved, but effectiveness against tough stains deteriorates
Solution Approach 1:
The patent pre-attaches floor sheets to the steam appliance head before use, allowing the sheets to be pre-treated with cleaning chemicals and positioned in advance. This preliminary action ensures the sheets are ready to handle various stain types from the start, combining the benefits of pre-wetting with enhanced chemical treatment for tougher stains.
Solution Approach 2:
The patent uses cellulosic material as the base substrate and combines it with various chemical treatments including surfactants, solvents, and cleaning agents. This composite approach creates a multi-functional floor sheet that can handle both soluble and tough stains, achieving versatility across different stain types while maintaining cleaning effectiveness.
3Reliability
If scrubbing strips are added to floor sheets, then stain removal capability is improved, but device complexity and ease of operation deteriorate due to flipping requirements
Solution Approach 1:
The patent combines the floor sheet and scrubbing elements into a single integrated disposable unit. The cellulosic floor sheet is pre-attached to the appliance head with scrubbing capabilities built into the sheet itself, eliminating the need for separate scrubbing strips and flipping mechanisms. This merger maintains stain removal capability while simplifying the overall device structure and operation.
Solution Approach 2:
The patent employs disposable floor sheets that are discarded after single use, eliminating the complexity of reusable scrubbing strip mechanisms that require flipping and repositioning. The disposable nature of the sheets allows for integrated scrubbing features without adding long-term device complexity, as the entire assembly is replaced rather than maintained.
4Power
If water with high surface tension is used for steam cleaning, then steam generation is effective, but streaking increases due to poor wetting
Solution Approach 1:
The patent modifies the chemical parameters of the cleaning solution by adding surfactants and other wetting agents to the water used in steam generation. These chemical additives reduce the surface tension of the water, improving its wetting properties and preventing streaking while maintaining the effectiveness of steam generation for cleaning.
Solution Approach 2:
The patent introduces surfactants as intermediary substances between the steam/water and the floor surface. These surfactants act as mediators that reduce surface tension and improve wetting, allowing the steam cleaning system to effectively clean without leaving streaks, thus resolving the contradiction between steam power and streak-free results.
