Ported Brush Applicator With Tapered Mesa For Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brush applicators tend to leak and suffer damage due to poor design, particularly when users grasp the brush to remove them from containers, leading to ineffective and unreliable application of liquid materials.
Innovation Solution
A ported brush applicator design featuring a brush with bristles attached to a ferrule, an applicator base cap with a tapered through hole, and fluid ports that allow liquid flow from the container through the cap and into the bristles, preventing leakage and damage by securing the brush to the cap without allowing rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional brush applicators are designed with simple attachment to containers, then ease of operation is improved, but reliability deteriorates due to leakage and brush damage
Solution Approach 1:
The applicator is divided into distinct functional segments: a brush portion with bristles, a ferrule section, and a cap portion with a mess base. This segmentation allows each part to perform its specific function optimally while reducing stress concentration points that could lead to failure. The mess base specifically segments the liquid flow path to prevent direct contact between liquid and the brush attachment point.
Solution Approach 2:
The mess base acts as an intermediary component between the container and the brush ferrule. It mediates the liquid flow by providing a controlled passage that prevents liquid from reaching the ferrule-brush interface, thereby protecting the attachment point from liquid-induced damage while maintaining the simplicity of operation.
2Ease of operation
If brush applicators allow direct liquid contact with the brush attachment area, then ease of material application is improved, but brush attachment strength deteriorates leading to damage
Solution Approach 1:
The mess base serves as a protective intermediary that blocks liquid from reaching the ferrule-brush interface. It provides a controlled liquid passage that allows material application to proceed easily while preventing liquid from compromising the structural integrity of the brush attachment point.
Solution Approach 2:
The mess base structure is designed beforehand to cushion and redirect liquid flow away from critical attachment points. By anticipating potential liquid intrusion paths, the design preemptively blocks these paths, protecting the brush-ferrule-cap assembly from liquid-induced weakening before damage can occur.
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 design provides a leak-proof and robust method for applying liquids, ensuring the brush remains securely attached to the cap, preventing damage and ensuring efficient material distribution without leakage.
Implementation Method 1
at least one fluid port having a first end in the plurality of bristles and a second end in the at least one tapered through hole, the fluid port configured for enabling the liquid material to flow from the cap opening, through the applicator base mesa, the at least one fluid port, and into the plurality of bristles
