Nested Brush Assembly for Misplacement Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional brush systems for cleaning containers are prone to microbial growth due to improper storage and small brushes are easily misplaced, leading to inefficiencies in cleaning.
Innovation Solution
A brush assembly with multiple brushes of different sizes secured to a handle, where the cap can be removed to expose the inner brushes, ensuring they are not misplaced and facilitating easy access for cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple small brushes are provided separately, then cleaning versatility is improved, but brushes are easily misplaced and lost
Solution Approach 1:
The patent combines multiple separate brushes (main brush, first auxiliary brush, second auxiliary brush) into a single integrated brush assembly with a common handle. This merging ensures all brushes remain together and cannot be misplaced, while still providing cleaning versatility for different surfaces and container types.
Solution Approach 2:
The patent employs a nested configuration where the first auxiliary brush is housed within the inner chamber of the handle, and the second auxiliary brush is housed within the inner chamber of the first auxiliary brush. This nesting arrangement compactly stores multiple brushes in a hierarchical manner, preventing misplacement while maintaining accessibility.
2Reliability
If brushes are stored inside the handle, then organization and prevention of misplacement is improved, but access to inner brushes becomes difficult
Solution Approach 1:
The patent segments the brush assembly into modular components: a main brush attached to the handle, a first auxiliary brush stored in the handle's inner chamber, and a second auxiliary brush stored in the first auxiliary brush's inner chamber. This segmentation allows each brush to be accessed independently while maintaining organized storage, with the nested structure enabling sequential access to inner brushes.
3Quantity of substance
If a hollow handle structure is used, then storage space for inner brushes is improved, but device complexity increases
Solution Approach 1:
The patent utilizes a nested doll configuration where the handle contains an inner chamber that houses the first auxiliary brush, which in turn contains an inner chamber housing the second auxiliary brush. This nested structure efficiently maximizes storage capacity within the handle volume without requiring complex external mechanisms, as each nested level provides additional storage space.
Data Source
AI summary
A brush assembly including a handle with a main brush, a first auxiliary brush detachably engaged with a cap, and a second auxiliary brush extending from the cap is described. The cap, when removed from the handle, exposes the first auxiliary brush. Disengagement of the cap from the first auxiliary brush exposes the second auxiliary brush.
