Detachable Portable Extractor for Floor and Handheld Carpet Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carpet extractors lack a versatile and efficient system for both floor cleaning and portable cleaning operations, with limited flexibility in fluid delivery and recovery systems, and often require complex assembly and disassembly processes.
Innovation Solution
A surface cleaning apparatus featuring a portable extractor with a detachable and removably mounted pod that includes a suction source, fluid delivery system, and diverter valve configuration, allowing for seamless transition between floor cleaning and portable cleaning modes, with integrated noise reduction and easy maintenance features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the extractor is designed as a fixed floor cleaning system, then cleaning effectiveness on floor surfaces is improved, but portability and versatility for other cleaning operations deteriorates
Solution Approach 1:
The extractor is divided into two main segments: a base unit with the suction source and a removable pod containing the recovery tank and fluid delivery system. This segmentation allows the pod to be detached and used as a portable handheld extractor, while the base unit provides stable floor cleaning operation. The suction source remains in the base unit and connects to the pod through detachable connections, enabling both fixed and portable cleaning modes.
Solution Approach 2:
The extractor is designed to perform multiple functions through a single integrated system. The base unit with suction source can handle floor cleaning operations, while the removable pod with recovery tank and fluid delivery system enables portable handheld extraction. The same suction source serves both floor cleaning and portable extraction functions, making the device universal for different cleaning scenarios.
2Adaptability or versatility
If the extractor uses a complex assembly system for floor cleaning operations, then cleaning functionality is improved, but ease of operation and setup deteriorates
Solution Approach 1:
The extractor employs segmented design with clearly defined connection interfaces between the base unit and pod. The detachable connections include alignment features and simple engagement mechanisms that allow users to assemble and disassemble the components without tools or complex procedures. The fluid delivery system and recovery tank are integrated into the pod as a single removable unit, simplifying the assembly process.
3Productivity
If the extractor maintains continuous fluid communication between recovery tank and suction nozzle, then cleaning efficiency is improved, but fluid management and noise control deteriorates
Solution Approach 1:
The extractor uses a dynamic diverter valve that can switch fluid pathways based on operational mode. During floor cleaning, the valve maintains continuous fluid communication between the recovery tank and suction nozzle for optimal cleaning efficiency. When transitioning to portable mode or during maintenance, the valve dynamically redirects fluid flow, allowing the suction nozzle to be isolated from the recovery tank, thereby reducing noise and improving fluid management.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and flexible cleaning operations by allowing the extractor to be used both as a floor cleaner and a portable device, with improved noise management and simplified maintenance, enhancing user convenience and cleaning effectiveness.
Implementation Method 1
a source of suction in fluid communication with the working air conduit to draw the cleaning fluid from the surface to be cleaned and through the nozzle and the working air conduit to the recovery tank

AI summary
An extraction cleaner for a floor surface comprises a portable extractor and a base adapted to be moved to perform a cleaning operation on the floor surface when the portable extractor is operably mounted to the base, wherein the portable extractor can be used as a standalone extractor when detached from the base. The portable extractor includes a suction hose for manually suctioning fluid from the floor surface, a recovery tank interconnected to the suction hose for receiving recovered fluid from the floor surface, and a fluid delivery system for dispensing a cleaning fluid onto the floor surface. One or more connections are made between the base and components of the portable extractor when the portable extractor is operably mounted to the base.
