Bottle Brush with Elliptical Cavity for Straight Fiber Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle cleaning utensils face inefficiencies in cleaning wide-necked bottle teats due to the need for adapted teat brushes, which result in bent fibers and reduced cleaning effectiveness when stored in conventional bottle brush handles.
Innovation Solution
A bottle cleaning utensil with a grip handle and storage cavity of non-traditional geometry, such as elliptical, rectangular, or diamond-shaped cross-section, designed to accommodate a teat brush with radially oriented straight fibers, ensuring the fibers remain straight and maintain cleaning capacity while allowing for compact and ergonomic storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the diameter of the teat brush is adapted to clean wide base teats, then the cleaning effectiveness of wide-necked bottle teats is improved, but the handle size increases and ergonomics deteriorate
Solution Approach 1:
The cleaning utensil is divided into two separate brushes: a bottle brush with a standard-sized handle for ergonomic gripping, and a separate teat brush with a larger cleaning head for wide base teats. The teat brush can be stored in a cavity within the bottle brush handle, allowing each component to be optimized for its specific function without compromising the other.
Solution Approach 2:
The teat brush is nested within the bottle brush handle, specifically in a storage cavity. This allows the larger teat brush to be accommodated within the smaller bottle brush structure, maintaining compact overall size while preserving the cleaning capabilities of both brushes.
2Volume of moving object
If the teat brush is stored in the bottle brush handle, then the utensil remains compact, but the fibers of the teat brush become bent and cleaning effectiveness is reduced
Solution Approach 1:
The storage cavity in the bottle brush handle is designed with specific dimensional characteristics to accommodate the teat brush. The cavity has a cross-section with a major axis that matches the diameter of the teat brush cleaning head, allowing the brush to be stored without bending its fibers. This localized design ensures that only the minimal portion of the teat brush is stored, preserving the straightness and cleaning effectiveness of the majority of the fibers.
3Device complexity
If a traditional cylindrical storage cavity is used, then the structure is simple, but it cannot accommodate teat brushes with wide base teats without bending fibers
Solution Approach 1:
The storage cavity in the bottle brush handle features an asymmetric cross-sectional geometry rather than a traditional cylindrical shape. The cavity has a major axis and a minor axis, creating an elongated space that matches the dimensional requirements of the teat brush. This asymmetric design provides sufficient space for the teat brush to be stored without bending its fibers, while maintaining relative structural simplicity.

AI summary
Said cleaning utensil includes a bottle brush (2) having a gripping handle (4) that is combined with a bottle-cleaning head (5), the gripping handle (4) including a storage cavity (7) wherein is removably inserted a nipple brush (3), including a gripping handle (9) and a nipple-cleaning head (10) that has radially positioned, substantially straight fibers. Additionally, the storage cavity (7) has a transverse cross-section having a large axis and a small axis, and the cleaning head of the nipple brush (3) has, in the transverse cross-section thereof, a maximum size substantially equal to the large axis of the storage cavity (7) such that the fibers of the portion of the nipple-cleaning head (10) that are positioned in the storage cavity at the large axis remain straight.
