Foam Dispensing Cleaning Tool for Inverted-Position Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning tools with foaming mechanisms are ineffective when used in inverted positions and require manual effort to dispense foam, as they rely on a specific orientation and mechanism that can be difficult to operate with one hand.
Innovation Solution
A cleaning tool design featuring a handle with a foaming mechanism that includes a chamber, air pocket, air tube, fluid reservoir, and foaming pump, allowing for the creation and dispensing of foam in any orientation, with an actuator to build pressure and ensure proper mixing of air and fluid, and features like compressed air cartridges and one-way valves to maintain pressure and prevent vacuum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional foaming mechanism is used with the pump above the fluid and air pocket, then foam can be dispensed in upright position, but the mechanism does not work effectively when inverted
Solution Approach 1:
The patent inverts the traditional foaming mechanism configuration by placing the foaming pump below the fluid and air pocket instead of above, enabling the mechanism to function effectively in inverted positions while maintaining upright position capability
Solution Approach 2:
The patent introduces an air tube as an intermediary component that extends into the air pocket to provide a dedicated air supply path to the foaming pump, ensuring consistent foam generation regardless of container orientation
2Ease of operation
If a push pump mechanism is used, then foam can be generated, but the user must push or translate the mechanism which is difficult to accomplish with one hand
Solution Approach 1:
The patent replaces the manual push pump mechanism with a pressure-building actuator system that can be operated more easily, reducing the physical effort and complexity required for one-handed operation
Solution Approach 2:
The foaming mechanism is designed to automatically draw air through the air tube and mix it with fluid when pressure is applied, eliminating the need for complex manual pumping actions by the user
3Reliability
If the air tube end remains above liquid level, then air can enter the air tube for foam production, but liquid will enter the air tube when inverted, preventing foam production
Solution Approach 1:
The air tube acts as an intermediary that extends into the air pocket, providing a dedicated air supply pathway that prevents liquid contamination while ensuring consistent air delivery for foam production in any orientation
Solution Approach 2:
The air tube is strategically positioned within the air pocket at a specific location where it can reliably access air without being contaminated by liquid, creating a localized quality zone that maintains foam production capability
