Needle Injection Carpet Extraction for Low-Moisture Deep Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carpet extraction methods often fail to effectively clean deep within carpet fibers and backing, leading to prolonged drying times and incomplete removal of soiled fluid, as they typically saturate the carpet and do not penetrate deeply enough.
Innovation Solution
A carpet extractor with fluid delivery needles that penetrate the carpet surface to inject cleaning solution directly into the nap, combined with a suction system to remove soiled fluid, along with an agitator to enhance cleaning, allowing for deep cleaning without saturating the carpet backing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional fluid delivery methods are used to apply cleaning fluid to carpet surface, then the carpet surface is wetted for cleaning, but the carpet fibers and backing become saturated leading to long drying time
Solution Approach 1:
The invention transitions from surface-level fluid application to deep subsurface injection by penetrating the carpet nap with needles. This dimensional change allows cleaning fluid to be delivered at the base of the carpet fibers rather than on the surface, enabling thorough cleaning while allowing the surface to remain relatively dry and dry quickly.
Solution Approach 2:
The needle acts as an intermediary device that bridges the gap between the cleaning fluid and the deep carpet fibers. By using this intermediary injection mechanism, the fluid is delivered precisely where needed without saturating the upper carpet layers, thus reducing drying time while maintaining cleaning effectiveness.
2Quantity of substance
If conventional fluid delivery methods are used, then cleaning fluid is applied to carpet surface, but soiled fluid is not removed from deep within carpet fibers and backing
Solution Approach 1:
The injection system delivers cleaning fluid to the base of the carpet fibers through needle penetration, accessing deep-seated soils that surface application cannot reach. This dimensional delivery approach ensures reliable removal of embedded contaminants while the suction system extracts soiled fluid from the same deep locations.
Solution Approach 2:
The invention replaces the conventional mechanical spray and agitation system with a needle-based injection system combined with suction. This substitution allows direct fluid delivery to fiber bases and efficient extraction of soiled fluid, achieving more reliable cleaning of deep carpet contaminants.
3Reliability
If carpet is agitated to enhance cleaning, then cleaning effectiveness is improved, but carpet fibers become more saturated extending drying time
Solution Approach 1:
The invention replaces mechanical agitation (brushing) with a needle injection system that delivers fluid directly to the base of carpet fibers. This substitution eliminates the need for aggressive surface agitation that saturates fibers, while still achieving deep cleaning through precise fluid delivery and suction extraction, thus reducing drying time.

AI summary
An extractor has a plurality of fluid delivery needles mounted to a housing in fluid communication with a fluid distribution system and positioned to penetrate a carpet surface to deliver a cleaning solution below the surface of the carpet and into the carpet nap. Soiled cleaning fluid is removed from the surface with suction. A method of cleaning a carpet or a pet coat having a nap comprises injecting cleaning fluid, such as a foam detergent, directly into the nap and removing soiled cleaning fluid from the carpet.
