Elastomer Spout Paintbrush Holder Sealing and Gravity Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paintbrush holders are inefficient in preventing drying out and damage, hinder painting due to rubber collars, are not completely airtight, cause hair damage, occupy excessive space, and are not portable or environmentally friendly.
Innovation Solution
A paintbrush holder with a spout-shaped part made of elastomer that fits the brush head, providing a fluid-tight seal and supporting the brush handle to prevent drying, while allowing for easy cleaning and adjustment to various brush sizes, made from materials like PP or PE with specific dimensions and angles to minimize hair damage and maximize protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rubber collar is used around the brush handle to provide an airtight seal, then the brush is protected from drying out, but the collar hinders painting and causes a dirty brush handle after use
Solution Approach 1:
The harmful rubber collar is completely removed from the brush handle. Instead, a spout-shaped part is used that fits over the brush head without contacting the handle, eliminating the source of contamination while maintaining protection through a fluid-tight seal at the brush head interface
Solution Approach 2:
The spout-shaped part acts as an intermediary element between the container and the brush. It provides the sealing function without directly contacting the brush handle, thereby preventing contamination of the handle while maintaining the protective seal
2Adaptability or versatility
If the container is made large to hold multiple brushes and fluids, then storage capacity increases, but it occupies excessive space and is not portable
Solution Approach 1:
The holder is designed to accommodate multiple brushes of different sizes through the spout-shaped part that can adapt to various brush head diameters. The same compact container structure serves multiple functions: storing multiple brushes, holding cleaning fluids, and providing protection, thereby increasing versatility without proportionally increasing volume
Solution Approach 2:
The spout-shaped part is designed with flexible dimensions that can adapt to different brush sizes. The elastomer material allows the spout to conform to various brush head diameters, enabling a single compact container to hold multiple brushes of different sizes without requiring a large fixed volume
3Volume of moving object
If the container is made compact for portability, then it fits in pockets and is easy to transport, but it cannot properly store multiple brushes and fluids
Solution Approach 1:
Multiple brushes are stored nested within the compact container by inserting them through the spout-shaped part. The spout acts as an entry point that allows brushes to be arranged vertically within the limited container volume, maximizing space utilization while maintaining portability
Solution Approach 2:
The spout-shaped part extends vertically from the container, creating an additional dimensional space for brush storage. This vertical arrangement allows multiple brushes to be stored in a compact footprint, transforming the storage problem from a two-dimensional area constraint to a three-dimensional vertical arrangement
4Reliability
If a tapered container is used to fit brush heads, then the brush can be stored airtight, but the tapering angle causes squeezing of the hair and damage to the tips
Solution Approach 1:
The spout-shaped part is designed with specific local dimensions that match the brush head geometry. The elastomer material provides localized flexibility and sealing at the brush head interface without applying compressive forces to the brush hair, thereby maintaining the seal while preventing hair damage
Solution Approach 2:
The spout-shaped part uses elastomer material with specific mechanical properties (flexibility and elasticity) that allow it to conform to the brush head shape without excessive compression. The material parameters are selected to provide adequate sealing while maintaining brush hair integrity
