Breast Pump Segmentation for Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing breast pump systems are noisy, uncomfortable, and lack discreet operation due to their large size and direct milk storage configuration, often requiring frequent cleaning and lacking advanced control features or memory devices to optimize pumping settings.
Innovation Solution
A low-volume breast pump system with a soft plastic or silicone breast shield that resembles a baby's mouth, featuring a remote milk storage configuration, continuous pumping to reduce noise, and smartphone app control for detailed settings and data tracking, using a vacuum cylinder to enable a smaller, quieter pump design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a larger pump is used to ensure sufficient pumping capacity, then pumping performance is improved, but noise level increases
Solution Approach 1:
The pump system is divided into two separate pumps: a first pump for suction and a second pump for milk collection. This segmentation allows each pump to be smaller and operate more quietly while maintaining overall pumping effectiveness, directly resolving the contradiction between pumping capacity and noise level.
2Productivity
If milk storage is directly connected to the breast shield, then milk collection efficiency is improved, but user comfort and discretion deteriorate
Solution Approach 1:
The milk storage container is extracted from direct connection to the breast shield and positioned remotely. The system uses separate tubing for suction and milk collection, allowing the storage container to be placed away from the breast area. This enables discreet pumping and improves user comfort while maintaining milk collection efficiency through the dedicated milk collection pump.
3Device complexity
If a single flow path is used for both suction and milk collection, then device complexity is reduced, but pump cleaning frequency increases
Solution Approach 1:
The system uses separate flow paths: a first tube for suction and a second tube for milk collection. This segmentation prevents milk from entering the suction pump, eliminating the need to clean the suction pump after each use and reducing overall maintenance frequency despite increased device complexity.
4Strength
If hard plastic breast shields are used for durability, then strength is improved, but user comfort deteriorates
Solution Approach 1:
The breast shield is made of soft plastic or silicone polymer material that resembles a baby's mouth. This composite material approach provides both durability and comfort, allowing the shield to be gentle on the user's skin while maintaining structural integrity during use.

AI summary
A non-therapeutic method of using a breast pump system to express breast milk A breast pump system having a suction tubing, a milk tubing, a pump, a three way vent valve, a milk bottle, an isolation valve and a breast shield, wherein the first end of the suction tubing and the first end of the milk tubing are fluidly connected to the pump; wherein the second end of the suction tubing and the second end of the milk tubing are fluidly connected to the breast shield; wherein the three way vent valve is fluidly connected between the pump and the breast shield on the suction tubing; wherein the milk bottle is fluidly connected on the milk tubing between the breast shield and the pump; and wherein the isolation valve is connected on the milk tubing between the milk bottle and the pump. The method comprises pumping, semi venting and final venting steps that are repeated. The cycle time is less than 5 seconds.
