Nested Male-Female Brush System for Consistent Pipe Flux Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for applying pipe joining agents, such as flux and adhesives, often result in inconsistent application to pipe surfaces, leading to suboptimal joining processes due to incorrect amounts or insufficient coverage.
Innovation Solution
A system comprising a male and female brush design, where the male brush is inserted into a container to pick up the agent and then inserted into the pipe to apply it internally, while the female brush applies the agent externally, ensuring complete surface coverage with a single insertion, with brush sizes correlated to the pipe diameter to ensure thorough application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional methods are used to apply pipe joining agents, then the application process is simple, but the coverage and consistency of agent application are insufficient
Solution Approach 1:
The brush system is divided into two separate components: a male brush for internal surface application and a female brush for external surface application. This segmentation allows each brush to be optimized for its specific function, ensuring consistent and complete coverage of respective surfaces while maintaining operational simplicity through modular design
Solution Approach 2:
The male brush is designed to be inserted through the female brush, creating a nested configuration during the dipping process. This nesting allows both brushes to be simultaneously loaded with agent from the same container, ensuring consistent application to both internal and external surfaces while simplifying the overall application process
2Area of stationary object
If a single brush is used for both internal and external surfaces, then the device is simple, but complete coverage of all surfaces cannot be achieved
Solution Approach 1:
The application tool is segmented into a male brush component for internal surfaces and a female brush component for external surfaces. This division enables complete coverage of all pipe surfaces by assigning specific functional responsibilities to each component, with the male brush accessing the internal bore and the female brush treating the external circumference
Solution Approach 2:
The male and female brush components are merged into a single integrated system that can be simultaneously dipped into the agent container. This combination allows both brushes to be loaded with agent in one operation and applied to their respective surfaces, achieving complete surface coverage while maintaining operational efficiency
3Quantity of substance
If excessive agent is applied, then coverage is sufficient, but the amount of agent used increases and waste occurs
Solution Approach 1:
Each brush is designed with specific bristle characteristics optimized for its intended surface: the male brush has bristles configured for effective internal surface contact, while the female brush has bristles optimized for external surface application. This local optimization ensures adequate coverage with appropriate agent quantities while minimizing waste through efficient application to the correct surfaces
Solution Approach 2:
The brush design incorporates sufficient bristle length and density to ensure complete surface coverage in a single application pass, eliminating the need for multiple applications that would result in excessive agent use. The brushes are sized to extend slightly beyond the pipe surfaces, ensuring full coverage without requiring over-application

AI summary
A system for applying a pipe joining agent, such as flux, primer or adhesive, to pipe structure surfaces. The system includes a male brush that cooperates with a female brush that is removably mounted on a container than contains the agent to be applied. The male brush can be inserted through the female brush and into the container to pick up the agent. As the male brush is withdrawn from the container, the female brush wipes excess agent from the male brush so that the female brush picks up agent thereon. The male brush can then be inserted into the end of a pipe structure to apply the agent to the interior surface of the pipe structure. Also, the female brush can be removed from the container and then inserted over the end of a pipe structure to apply the agent to the exterior surface of a pipe structure.
