Removable Extraction Nozzle and Spray Unit for Carpet Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carpet extractors lack a modular and efficient system for delivering cleaning fluid and recovering spent fluid and dirt, which can lead to inadequate cleaning and maintenance challenges.
Innovation Solution
A surface cleaning apparatus with a modular nozzle/spray unit that includes a fluid delivery system for depositing cleaning fluid and a fluid recovery system for removing spent fluid and dirt, featuring a removable modular unit with a primary and auxiliary fluid distributor, and an extraction nozzle integrated with a suction source for effective cleaning and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional non-modular extractor design is used, then the device structure is simple, but the cleaning efficiency and maintenance accessibility are inadequate
Solution Approach 1:
The extractor is divided into modular components including a removable nozzle assembly, fluid distributor system, and recovery tank that can be independently accessed and maintained. This segmentation allows for improved cleaning efficiency through targeted application while maintaining structural simplicity through standardized modular interfaces.
2Ease of repair
If a conventional fixed design is used, then the device is easy to manufacture, but the maintenance accessibility is poor
Solution Approach 1:
The fluid distributor and nozzle assembly are designed as extractable modular units that can be removed from the main body for easy maintenance and cleaning. This extraction design provides excellent maintenance accessibility while the standardized connection interfaces keep manufacturing complexity manageable.
3Productivity
If cleaning fluid delivery is not focused, then the device structure is simple, but the stain treatment effectiveness is insufficient
Solution Approach 1:
The fluid distributor system incorporates adjustable spray patterns and targeted delivery mechanisms that concentrate cleaning fluid precisely where needed on stains. This local quality approach enhances stain treatment effectiveness while the modular design keeps the overall system relatively simple.

AI summary
An extraction cleaner for a floor surface comprises a fluid delivery system for storing cleaning fluid and delivering the cleaning fluid to the surface to be cleaned and a fluid recovery system for removing the spent cleaning fluid and dirt from the surface to be cleaned and storing the spent cleaning fluid and dirt. The fluid delivery system includes at least one fluid distributor and the fluid recovery system includes an extraction nozzle. The extraction nozzle and the at least one fluid distributor can be simultaneously removed from the extraction cleaner.
