Undulating Brush Holder Structure for Faster Cosmetic Brush Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetics brush holders with flat bases and cylindrical sidewalls cause brushes to cluster together, limiting air flow and making it difficult for wet brushes to dry properly.
Innovation Solution
A cosmetics brush holder with an undulating pattern on the sidewall and a brush retainer that secures brushes outside the interior cavity, allowing for better air circulation and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flat base and cylindrical sidewall are used in the brush holder, then the structure is simple and easy to manufacture, but the brushes cluster together at one side limiting air flow and drying
Solution Approach 1:
The holder body is divided into multiple functional zones: an interior cavity for holding brushes and an exterior cavity with undulating patterns for air circulation. This segmentation allows the structure to simultaneously provide simple manufacturing (through modular design) and improved air flow (through the exterior cavity pattern).
Solution Approach 2:
The solution moves from a two-dimensional flat base to a three-dimensional structure with an exterior cavity featuring undulating patterns. This dimensional change creates additional air circulation pathways outside the traditional interior cavity, enabling better air flow without complicating the basic manufacturing process.
2Ease of operation
If brushes are placed inside the interior cavity, then they are contained and organized, but they cluster together making it difficult for wet brushes to dry properly
Solution Approach 1:
The holder is segmented into two distinct functional spaces: the interior cavity maintains brush organization while the exterior cavity with undulating patterns provides dedicated air circulation pathways. This segmentation allows brushes to remain organized while simultaneously enabling effective drying through the exterior cavity's air flow channels.
Solution Approach 2:
The undulating pattern on the exterior cavity acts as an intermediary structure that facilitates air flow between the interior cavity where brushes are held and the external environment. This intermediary design enables organized brush storage while maintaining effective drying capability through enhanced air circulation.
3Object-affected harmful factors
If a brush retainer extends outward from the outer sidewall surface, then brushes can be secured outside the interior cavity for better air circulation, but the device complexity increases
Solution Approach 1:
The brush retainer is merged with the holder body as an integrated component rather than a separate attachment. This combining approach allows the retainer to extend outward from the outer sidewall surface for improved air circulation while avoiding the complexity of separate assemblies, as the retainer is formed as part of the monolithic holder structure.

AI summary
A cosmetics brush holder includes a holder base defined at a lower end of the cosmetics brush holder, the holder base defining an inner base surface and an outer base surface opposite the inner base surface; and a holder sidewall defining an undulating pattern about a circumference of the holder sidewall, the holder sidewall defining an inner sidewall surface and an outer sidewall surface opposite the inner sidewall surface, the inner sidewall surface defining a plurality of alternating inner sidewall grooves and inner sidewall ridges; and an interior cavity defined by the inner base surface and the inner sidewall surface and configured to receive cosmetics brushes.
