System, method and device for cleaning using a sub-surface fluid injector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carpet cleaning devices are unable to effectively clean through the sub-surfaces, middles, and surfaces of carpets and other fabrics, failing to remove reoccurring spots and embedded odors like pet urine.
Innovation Solution
A sub-surface pulsation fluid injector system that uses a flexible tube with a pointed end to penetrate carpet membranes and discharge cleaning fluids in a controlled manner, allowing for simultaneous extraction of fluids through the carpet surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional carpet cleaning devices are used, then surface cleaning is achieved, but sub-surface cleaning is not effective
Solution Approach 1:
The cleaning device is segmented into multiple functional components: a fluid injector for sub-surface fluid delivery, a vacuum extractor for fluid removal, and a pointed tube for membrane penetration. This segmentation allows each component to perform its specific function effectively, achieving deep sub-surface cleaning without requiring a completely complex integrated system.
Solution Approach 2:
A flexible tube with a pointed end acts as an intermediary element that penetrates the carpet membrane to deliver cleaning fluid to the sub-surface area. This intermediary component enables the fluid injector to reach deep into the carpet padding and backing without requiring the entire device to be complex, simplifying the overall structure while achieving deep cleaning.
2Reliability
If cleaning fluid is applied to carpet surface, then surface stains are treated, but embedded odors and reoccurring spots are not removed
Solution Approach 1:
The system performs preliminary action by injecting cleaning fluid directly into the sub-surface area before the main cleaning process. The fluid injector delivers cleaning solution deep into the carpet padding and backing where embedded odors and contaminants reside, preparing the area for effective contaminant removal during the vacuum extraction phase.
Solution Approach 2:
The system uses hydraulic principles to inject cleaning fluid under pressure into the sub-surface carpet areas through the pointed tube. This pneumatic-hydraulic mechanism enables the cleaning fluid to penetrate deep into the carpet structure, reliably reaching embedded contaminants without requiring complex manual operation.
3Manufacturing precision
If vacuum extraction is applied only to carpet surface, then surface fluids are removed, but sub-surface contaminants remain
Solution Approach 1:
The vacuum extraction system is merged with the fluid injector system, allowing the same pointed tube and flexible conduit to serve dual purposes: delivering cleaning fluid to sub-surface areas and then extracting the fluid along with dissolved contaminants. This merging eliminates the need for separate deep-extraction nozzles, maintaining operational simplicity while achieving deep extraction.
Solution Approach 2:
The pointed tube with flexible conduit serves multiple functions: it acts as both the fluid injection pathway and the vacuum extraction pathway. This multi-functional component enables deep sub-surface cleaning and extraction without requiring complex specialized nozzles for each function, reducing overall device complexity.
4Manufacturing precision
If pointed tube penetrates carpet membrane, then sub-surface access is achieved, but carpet damage may occur
Solution Approach 1:
The pointed tube is covered with a flexible conduit that allows the tube to bend and flex as it penetrates the carpet membrane and navigates through the carpet layers. This flexibility reduces the risk of damaging carpet fibers and backing materials, while still enabling accurate delivery of cleaning fluid to the sub-surface padding area.

AI summary
Systems, methods, and devices for cleaning a surface and sub-surface or flooring, such as a carpeted flooring and/or fabrics including carpet backing, padding, upholstery, mattress, etc., using a sub-surface fluid injector, such as a pulsation fluid injector are disclosed. The systems, methods, and devices enable spot cleaning a surface or flooring, such as a carpet and cleaning underneath the carpet surface, thereby eliminating reoccurring spots from spills and embedded odors, such as pet urine, using a sub-surface pulsation fluid injector to flush-clean through the sub-surfaces of the flooring thoroughly. The device of the disclosure safely provides a continuous free-flowing stream of fluid through all areas above and below the surface or flooring, for example the carpet face fibers, carpet backing and padding or underlay, in order to chemically treat, break down, carry out and/or remove certain contaminants embedded in the carpeted flooring.
