Modular Bottle Brush with Flexible Stem for Tight-Corner Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices fail to effectively scrub the various contours of infant nursing bottles and nipples, particularly after use with fatty liquids or liquids containing suspended solids, due to their inflexibility and inability to reach tight corners.
Innovation Solution
A modular and flexible interchangeable brush system with a handle featuring a flexible stem and interchangeable brushes, allowing for bending to reach difficult areas and featuring a spine-like configuration with resilient material to enhance flexibility and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid brush handle is used, then structural strength is improved, but the ability to reach tight corners and difficult contours deteriorates
Solution Approach 1:
The handle is divided into multiple segments including a rigid base portion and a flexible neck portion with articulation joints. This segmentation allows the handle to maintain structural strength in the base while achieving flexibility and bendability in the neck region to access tight corners and difficult contours of baby bottles and nipples.
Solution Approach 2:
The handle incorporates dynamic elements such as flexible materials and articulation joints that allow the neck portion to bend and flex during use. This dynamic design enables the brush to adapt to various cleaning angles and reach difficult areas while the rigid base maintains overall structural integrity.
2Ease of operation
If a flexible brush handle is used, then the ability to reach difficult contours is improved, but structural strength and stability deteriorates
Solution Approach 1:
The handle is segmented into a rigid base portion that provides structural strength and a flexible neck portion that provides bendability. This segmentation ensures that flexibility is concentrated where needed for reaching contours while the base maintains stability and strength.
Solution Approach 2:
Different portions of the handle have different mechanical properties: the base portion is rigid for strength, while the neck portion is flexible for contour access. This local differentiation of material properties resolves the contradiction between overall strength and localized flexibility.
3Device complexity
If a non-modular brush design is used, then device complexity is reduced, but the ability to replace worn parts deteriorates
Solution Approach 1:
The brush is designed as a modular system with separable components including an interchangeable brush head and a handle with integrated storage. The brush head can be detached and replaced independently, allowing users to replace only worn brushing elements without discarding the entire brush, thus improving repairability while maintaining reasonable complexity.
Solution Approach 2:
The handle incorporates a storage compartment that can hold multiple brush heads or additional cleaning accessories. This multi-functional design allows the same handle to work with different brush heads for various cleaning needs, reducing the need for multiple separate devices while enhancing versatility and ease of replacement.
4Ease of repair
If a modular interchangeable brush system is used, then ease of repair and part replacement is improved, but device complexity increases
Solution Approach 1:
The modular design segments the brush into a handle and interchangeable brush head components with simple connection mechanisms. This segmentation enables easy replacement of worn brush heads while the standardized connection keeps the overall system complexity manageable.
Solution Approach 2:
The brush head inserts into and is contained within the handle structure, with the handle's storage compartment accommodating the brush head when not in use. This nested arrangement integrates multiple functions (brushing and storage) into a unified structure, reducing the need for separate components and managing complexity.
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 modular brush system effectively cleans the interior of baby bottles and nipples by flexing to reach tight spaces and allowing for easy replacement of worn parts, ensuring thorough hygiene without the need for replacing the entire device.
Implementation Method 1
The flexible stem has at least one gap into which a resilient material is disposed. The location of the gap is at a bend location along a longitudinal axis of the handle.

AI summary
Modular and flexible interchangeable brush system to scrub a container. The brush system includes a handle having a first core and a second core. A sleeve is provided into which the first core and the second core are disposed. A flexible stem is removably connected to the first core of the handle. The flexible stem has at least one gap into which a resilient material is disposed. The location of the gap is at a bend location along a longitudinal axis of the handle. A first brush is operatively connected to the flexible stem, and a second brush is operatively connected to, and received within, the second core of the handle.
