Handle-Actuated Steam Mop Pump for Controlled Crevice Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mops are ineffective at cleaning dirt in small crevices and floor gaps, and require frequent repositioning due to limited cleaning surface area, while existing steam cleaners have inefficient steam distribution and require complex fabric attachment methods.
Innovation Solution
A steam mop with a water pump actuated by the angular movement of the mop handle, which pumps water from a reservoir to a boiler, allowing controlled steam generation and distribution to a steam pad for improved cleaning, eliminating the need for electric pumps and switches, and featuring a low-pressure, non-pressurized system for safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional mops are used to clean floors, then they can clean surface areas, but they are ineffective at cleaning dirt in small crevices and floor gaps
Solution Approach 1:
The steam mop head is designed with a fabric pad that can be pressed into small crevices and floor gaps, providing localized high-temperature steam cleaning exactly where dirt accumulates. The steam is delivered through the fabric pad itself, allowing targeted cleaning in hard-to-reach areas while maintaining overall cleaning effectiveness.
Solution Approach 2:
The invention transitions from conventional two-dimensional surface cleaning to three-dimensional cleaning by enabling steam penetration into crevices and gaps. The fabric pad structure allows steam to reach into vertical and depth dimensions of floor crevices, not just horizontal surface areas.
2Device complexity
If conventional mops are used with limited cleaning surface area, then they can be simple in structure, but they require frequent repositioning
Solution Approach 1:
The steam mop generates steam continuously through an onboard boiler system, allowing the user to clean large areas without frequent stops to refill water or reposition the mop. The continuous steam generation maintains cleaning action throughout the entire cleaning process, increasing productivity.
Solution Approach 2:
The steam mop head serves multiple functions: it cleans surface areas, penetrates crevices, and can be used with different fabric pads for various floor types. This multi-functionality reduces the need for multiple different cleaning tools and frequent repositioning for different cleaning scenarios.
3Device complexity
If steam cleaners use nozzles without large surface areas, then they can be simple in design, but they have inefficient steam distribution
Solution Approach 1:
The fabric pad acts as a flexible steam distribution surface that conforms to floor contours and crevices. The fabric material allows steam to distribute evenly across the entire pad surface area, ensuring reliable steam delivery to all cleaning zones while maintaining a simple nozzle design that simply delivers steam to the fabric.
Solution Approach 2:
The fabric pad contains porous structures that allow steam to pass through uniformly across its surface. The porous nature of the fabric ensures efficient steam distribution while maintaining a simple design without complex nozzle internal structures.
4Ease of operation
If steam cleaners use fabric pads secured by Velcro strips to cleats, then they can be easy to attach, but the cloth may not cover the front or back of the brush attachment properly
Solution Approach 1:
The fabric pad is designed to be self-aligning and self-securing through the Velcro attachment system. The fabric's own weight and the distributed Velcro attachment points along the edges allow the fabric to automatically position itself correctly, covering the brush attachment front and back without requiring precise manual alignment during installation.
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
Provides greater user control over steam generation, enhances cleaning effectiveness by allowing precise steam distribution to small areas, and ensures safer operation with a low-pressure system, enabling efficient cleaning of small crevices and gaps without the need for complex electric components.
Implementation Method 1
a water pump operatively connected to the handle and connected to the reservoir and the boiler, the water pump pumping water from the reservoir to the boiler in response to movement of the handle
Implementation Method 2
an electric boiler in the housing connected to the water pump and to the steam nozzle, the electric boiler generating steam from the water pumped by the water pump
Implementation Method 3
the electric boiler generating steam to be distributed by a fabric steam pad mounted on the steam pad frame attachment for cleaning

AI summary
A steam mop having a main body including a water pump and a boiler. Generation of steam is provided when the water pump is actuated by angular movement of the mop handle which changes the angle between the handle and mop head for operating a two way piston pump to pump water to the boiler. Steam is fed to a steam pad that may have a replaceable fabric pad fit snugly on the frame to distribute cleaning steam to the surface to be cleaned.
