Portable foam brush
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foam brushes used in cleaning applications are cumbersome due to their hose-tethered design, which limits mobility and can transfer debris to surfaces, and they require a hose for soap and air supply, restricting their use in certain locations.
Innovation Solution
A portable foam brush with a rechargeable battery-powered air compressor and a soap reservoir that allows for cordless operation, featuring a foaming chamber where air and soap mix to form foam, eliminating the need for a hose and enhancing mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If foam brush is tethered to hose for soap and air supply, then reliable foam generation is achieved, but mobility is limited and debris transfer occurs
Solution Approach 1:
The patent extracts the soap and air supply system from the external hose connection and integrates it into a self-contained portable unit. The foam brush includes an onboard soap reservoir, battery-powered air compressor, and foaming chamber that can generate foam independently without external hose connections, thereby eliminating mobility restrictions and debris transfer issues while maintaining reliable foam generation capability
Solution Approach 2:
The portable foam brush integrates multiple functions into a single device: it combines the soap storage reservoir, air compression system, foam generation chamber, and brush application tool into one self-sufficient unit. This multi-functional integration allows the device to operate autonomously without external connections, resolving the contradiction between reliability and mobility
2Productivity
If hose is used for soap and air supply, then continuous foam production is possible, but device complexity and mobility restrictions increase
Solution Approach 1:
The patent merges the soap supply system, air supply system, and foam generation system into a single integrated portable unit. The soap reservoir, air compressor, and foaming chamber are combined in one device, eliminating the need for separate hose connections and external equipment, thereby reducing overall system complexity while maintaining continuous foam production capability
Solution Approach 2:
The portable foam brush is designed as a self-sufficient system that carries its own soap reservoir and air compressor. The device serves itself by generating foam internally without requiring external hose connections or additional equipment, thereby simplifying the overall system while ensuring continuous operation
3Quantity of substance
If hose-tethered design is used, then soap and air supply is ensured, but access to certain locations is restricted
Solution Approach 1:
The patent segments the foam generation system into a portable, handheld unit that can be independently positioned and maneuvered. By dividing the system into compact, self-contained components (reservoir, compressor, foaming chamber, brush), the device can be easily transported and positioned in hard-to-reach areas without being constrained by hose length or routing requirements, while still ensuring adequate soap and air supply
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
The portable foam brush provides enhanced mobility and cleanliness by allowing foam generation without a hose, reducing debris transfer and enabling easier access to all areas, while maintaining efficient foam production.
Implementation Method 1
a battery-operated air compressor. The compressor can also be configured for supplying air to act upon the soap reservoir
Implementation Method 2
The actuation chamber is configured to be acted upon by air from the air compressor for moving the piston to decrease the size of the chamber for containing soap to dispense soap from that chamber
Implementation Method 3
In use, the soap and the air in the foaming chamber combine to form a foam

AI summary
A portable foam brush assembly having a base having a soap supply, a water supply, and an electrical supply. A foam brush wand is detachably dockable to the base and in electrical and fluid communication with the foam brush wand having battery pack, a peristaltic pump, a reservoir chamber, a foaming chamber, an air pump, a brush and a momentary release switch. The base water supply and the base soap supply, when activated, are configured to travel by a water supply hose and a soap supply hose to a tee in the base where they are combined in a combined hose to a base quick coupler that is connectable to a reciprocal foam brush wand quick coupler, which has a foam brush wand hose to deliver the water soap mixture to bladder in the foam brush wand.
