Handheld Extraction Cleaner for Simultaneous Spray and Vacuum
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carpet and upholstery extraction cleaners often require sequential spraying, agitation, and vacuuming, which can be inefficient and cumbersome, especially when dealing with localized stains or small areas, as they lack a portable and integrated solution for simultaneous cleaning and fluid extraction.
Innovation Solution
A portable spot cleaner device with a hand tool connected to a main unit via a flexible hose, featuring a vacuum pump, liquid pump, agitator, and electrical cable, allowing for simultaneous spraying, agitation, and fluid extraction in a single motion, with adjustable components for ease of use and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional floor cleaners are used for spot cleaning, then they can clean carpet surfaces, but they are cumbersome and inefficient for small areas due to sequential spraying, agitation, and vacuuming
Solution Approach 1:
The invention divides the cleaning system into two separate units: a main unit containing the vacuum pump and fluid storage, and a handheld tool containing the spray nozzle and agitator. This segmentation allows the handheld tool to be lightweight and maneuverable for spot cleaning, while the main unit provides the necessary power and fluid storage, resolving the contradiction between cleaning efficiency and device complexity.
Solution Approach 2:
The invention introduces a flexible hose connecting the main unit to the handheld tool, adding a spatial dimension that allows the user to move the handheld tool independently across different locations. This dimensional separation enables simultaneous spraying, agitation, and vacuuming operations to be performed on different portions of the carpet, improving productivity without requiring the entire device to be complex.
2Loss of time
If floor cleaners are dragged over carpet for cleaning, then cleaning can be performed, but the sequential process on different portions of carpet is time-consuming
Solution Approach 1:
The handheld tool is pre-filled with cleaning solution and the vacuum pump is pre-positioned in the main unit, allowing the user to immediately begin spraying and agitating stains without dragging the entire device across the carpet. This preliminary preparation of the handheld tool enables rapid response to spills and stains, reducing cleaning time while maintaining ease of operation.
Solution Approach 2:
The flexible hose acts as an intermediary between the main unit and handheld tool, allowing the vacuum pump to draw fluid through the hose passageway and deliver it to the spray nozzle. This intermediary connection enables the handheld tool to function independently for spot cleaning, eliminating the need to drag the entire device and significantly reducing cleaning time for localized stains.
3Adaptability or versatility
If hand tool spot cleaners are used, then localized stains can be treated, but they lack integrated vacuum and spray capabilities in a portable format
Solution Approach 1:
The invention extracts the heavy vacuum pump and fluid storage from the handheld tool and places them in the main unit, leaving only the essential spray nozzle and agitator components in the handheld tool. This extraction maintains the portability and light weight necessary for spot cleaning while providing access to integrated vacuum and spray capabilities through the flexible hose connection, thus achieving versatility without excessive weight.
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 convenient cleaning of small areas by allowing simultaneous spraying, agitation, and fluid extraction, improving cleaning efficiency and reducing user effort, while also providing a compact and storable design for easy handling and storage.
Implementation Method 1
The main unit comprises a vacuum pump. The flexible hose surrounds a hose passageway and is operatively connected to the vacuum pump in a manner such that the vacuum pump is capable of drawing fluid through the hose passageway.
Implementation Method 2
the vacuum pump is capable of drawing fluid through the vacuum inlet port and into the hose passageway
Implementation Method 3
The spray nozzle is operatively connected to the liquid pump in a manner such that the liquid pump is capable of forcing liquid out of the spray nozzle.
Implementation Method 4
The electric motor is operatively connected to the agitator in a manner such that operation of the electric motor causes the agitator to move relative to the grip portion.
