Paint Brush Scraping Relief for Efficient Paint Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scraping devices for paint brushes are inefficient due to limited effectiveness, requiring repeated brushing and taking up space, and often result in unintentional contact with the paint, leading to ineffective paint removal and bulkier designs.
Innovation Solution
A scraping device with a peripheral wall that encloses a scraping space and features a complete inner perimeter scraping relief, allowing for parallel scraping direction, reducing unintentional contact, and enabling efficient paint removal with a compact design suitable for standard paint packaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a slanting scraping wall is provided in the holder, then scraping function is provided, but the useful capacity of the holder is reduced
Solution Approach 1:
The scraping relief is configured to extend along the complete inner perimeter of the peripheral wall, transforming the scraping action from a vertical/diagonal movement to a horizontal circumferential path. This dimensional change allows the scraping surface to wrap around the holder interior, providing comprehensive scraping coverage without requiring a slanting wall that would reduce vertical capacity.
Solution Approach 2:
The scraping relief is divided into multiple segments or zones along the peripheral wall, with each segment contributing to the overall scraping function. This segmentation allows the scraping surface to be distributed around the holder perimeter, maximizing scraping effectiveness while maintaining full holder capacity.
2Ease of operation
If up and down movement with a roller is used for scraping, then scraping action is achieved, but unintentional contact with the product occurs
Solution Approach 1:
The scraping action is shifted from vertical up-and-down movement to horizontal circumferential movement along the inner perimeter of the holder. The scraping relief extends around the perimeter, allowing the roller to scrape by moving horizontally along the paint surface rather than vertically through it, eliminating unintentional contact.
3Area of stationary object
If a scraping relief extends along the complete inner perimeter, then scraping area is maximized, but device complexity increases
Solution Approach 1:
The scraping relief is integrated directly into the peripheral wall structure of the holder, merging the scraping function with the holder body. This integration eliminates the need for separate scraping components, achieving complete perimeter coverage while maintaining simple device construction.
Solution Approach 2:
The peripheral wall serves dual functions: it provides the structural boundary of the holder and simultaneously incorporates the scraping relief. This multi-functionality maximizes scraping area without adding separate components or increasing device complexity.

AI summary
The invention provides a scraping device (01) for a paint brush, the scraping device comprising a peripheral wall (02) that extends between an upper end (03) and a lower end (04), and enclosing a scraping space (05) between said upper end and said lower, end. On an inner side (10) turned towards the scraping space, the peripheral wall is provided with a scraping relief (11) that extends along a complete inner perimeter of the peripheral wall (02). The scraping device is provided with a bottom (07) and/or one or more engaging elements for resting on, preferably for coupling to, an upper edge of a holder, for example a tin (21). The scraping space is built for receiving the tip of a brush, and the scraping relief is configured for providing a scraping direction substantially parallel to the upper edge of the peripheral wall (02).
