Breast Pump Bra Cup With Elastic Compression Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing breast pump bras have openings that are too large, allowing the breast pump flange to wobble or slide out, and expose the breasts, compromising privacy and causing discomfort due to inadequate compression force.
Innovation Solution
A breast pump bra cup structure with a unique design featuring elastic compression areas and strategically positioned openings that form a compression force perpendicular to the cup surface, ensuring the flange is securely held while minimizing exposure, and incorporating cutting pieces and elastic strips for enhanced stability and privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the opening length is designed to be equal to the diameter of the breast pump flange to reduce compression pressure, then the insertion is easier, but the breast pump becomes easy to wobble or slide out when milk increases
Solution Approach 1:
The patent transitions from a single-dimensional opening (length only) to a two-dimensional opening structure with both length and width dimensions. The opening is designed with length L1 in the vertical direction and width W1 in the horizontal direction, creating an elliptical or rectangular aperture that provides both easy insertion and stable retention of the breast pump flange.
Solution Approach 2:
The patent changes the geometric parameters of the opening from a simple linear dimension to a two-dimensional area with specific length and width relationships. The opening length L1 is designed to be less than the flange diameter D, while the opening width W1 is designed to be between 0.05m to 0.15m, creating optimal compression conditions that prevent wobbling and sliding.
2Ease of operation
If the opening is made larger to facilitate breast pump insertion, then the ease of use improves, but the breasts are exposed too much, resulting in failure to protect privacy
Solution Approach 1:
The patent applies local quality by creating a focused, controlled opening area rather than a large exposed area. The opening is positioned locally at the center of the cup front surface, with specific dimensional constraints (length L1 < flange diameter D, width W1 = 0.05m to 0.15m), allowing breast pump insertion while minimizing overall breast exposure and protecting privacy.
3Ease of operation
If the opening length is increased to allow flange passage, then the insertion is facilitated, but the compression force of the bra on the flange becomes insufficient
Solution Approach 1:
The patent optimizes the opening dimensions by setting the length L1 to be less than the flange diameter D, and the width W1 to be between 0.05m to 0.15m. This parameter configuration allows the flange to pass through comfortably while maintaining sufficient compression force from the bra cup material around the opening, preventing the flange from wobbling or sliding out.
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 design provides sufficient compression to prevent the breast pump flange from wobbling or sliding out, while maintaining privacy and reducing arm fatigue for lactating women, allowing them to use the breast pump without exposing themselves excessively.
Implementation Method 1
a first elastic compression area is disposed between the first connecting part and the second connecting part; and a second elastic compression area is disposed between the first connecting part and the third connecting part

AI summary
A breast pump bra cup is provided. An elastic compression area can form an elastic compression force almost perpendicular to a surface of a cup and pointing to the inside of the cup when the bra is worn. A length direction of a first opening is the same as that of a second blind opening. The first opening, the first blind opening and one end of the second blind opening in the length direction intersect and are in a connected state. One end of a first blind opening limit line is connected with an O1 end of the second blind opening, so that the first blind opening coincides with the second blind opening in a direction close to the O1 end and is in a connected state. The opening on the bra cup can be stuffed into a breast pump flange while the length is smaller.
