Cordless Foam Brush Assembly With Dock Charging and Onboard Foaming
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, restricting access to certain areas and causing unwanted contamination.
Innovation Solution
A portable foam brush with a rechargeable battery-powered air compressor and a soap reservoir, allowing for cordless operation and independent air supply to create foam without a hose, featuring a soap reservoir filling valve assembly for controlled soap dispensing and a foaming chamber for efficient foam generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If foam brush is tethered to hose for soap and air supply, then foam generation capability is maintained, 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 the foam brush itself. The foam brush includes an integrated air compressor, soap reservoir, and foaming chamber that were previously external components connected via hose. This extraction eliminates the hose attachment system while maintaining foam generation capability.
Solution Approach 2:
The foam brush becomes self-sufficient by incorporating its own air compressor, soap reservoir, and foaming chamber. The device generates its own foam without requiring external connections for soap or air supply, making it portable and eliminating the need for hose tethering.
2Reliability
If hose is used for soap and air supply, then foam can be generated, but the hose can drag across floor picking up grit and debris
Solution Approach 1:
The patent removes the hose from the system entirely by integrating the air compressor and soap reservoir into the foam brush. This extraction eliminates the source of debris contamination that the hose represented, preventing grit pickup from the floor.
Solution Approach 2:
The self-contained design with integrated components eliminates the need for external hose connections, thereby preventing the hose from dragging across surfaces and picking up debris that could contaminate the cleaning process.
3Adaptability or versatility
If hose-tethered foam brush is used, then soap and air can be supplied, but access to certain locations on vehicle is restricted
Solution Approach 1:
The patent extracts the supply system from external hose connections and integrates it into the foam brush, enabling portable operation without hose constraints. This allows unrestricted access to difficult-to-reach areas on vehicles.
Solution Approach 2:
The foam brush transitions from a static, hose-tethered design to a dynamic, portable system with integrated power and supply components. The battery-operated air compressor and onboard soap reservoir enable the device to move freely and adapt to various cleaning positions.
4Productivity
If hose attachment is used for foam brush, then foam generation is possible, but the brush becomes cumbersome to use
Solution Approach 1:
The patent removes the cumbersome hose attachment system and integrates all necessary components (air compressor, soap reservoir, foaming chamber) directly into the foam brush, maintaining cleaning efficiency while dramatically improving usability.
Solution Approach 2:
The patent merges the air compressor, soap reservoir, foaming chamber, and brush components into a single integrated unit. This consolidation eliminates the need for separate hose connections and external supply systems, creating a unified portable device that is both efficient and easy to use.
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
Enhances mobility and reduces debris transfer by eliminating the need for a hose, enabling effective cleaning without tethering, while maintaining efficient foam generation and soap management.
Implementation Method 1
In use, the soap and the air in the foaming chamber combine to form a foam
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
