Breast Pump Connector Manifold for Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing breastpump systems require multiple connections and adapters for transitioning between single and double pumping modes, leading to complexity, potential for tube tangling or loss, and increased parts to manage.
Innovation Solution
A connector with a manifold featuring a three-way passageway and four ports, where tubes are permanently affixed, and a plug member allows for easy switching between single and double pumping modes with a leakage path to maintain consistent suction levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple adapters and connections are used for transitioning between single and double pumping modes, then the breastpump system can achieve both pumping modes, but the device complexity increases and the ease of operation deteriorates
Solution Approach 1:
The connector is designed with a universal structure that performs multiple functions: it serves as both a double-pumping connector and a single-pumping connector with the addition of a simple cap. The manifold body with multiple ports allows the same connector to adapt to different pumping modes without requiring mode-specific components.
Solution Approach 2:
The cap is designed to nest within the connector structure when attached to seal a port. This nesting approach allows the cap to be stored within or alongside the connector, minimizing the number of separate parts the user must manage while maintaining the ability to switch between pumping modes.
2Adaptability or versatility
If multiple adapters and connections are used for transitioning between single and double pumping modes, then the breastpump system can achieve both pumping modes, but the ease of operation deteriorates due to more parts to manipulate
Solution Approach 1:
The invention extracts the mode-switching functionality from a complex multi-component system and consolidates it into a simple cap attachment. By removing the need for multiple adapters and complex reconfigurations, the essential function of mode switching is achieved through a single, simple action of attaching or removing a cap.
3Adaptability or versatility
If tubes are made removable for single pumping, then the system can disconnect the inactive breastshield, but the reliability decreases due to potential tube misplacement or loss
Solution Approach 1:
The invention employs a disposable or easily replaceable cap rather than making the tubes themselves disposable. The cap serves as a temporary, simple component that seals the port when not in use, eliminating the need to handle, store, or protect the tubes from loss while maintaining the ability to configure for single pumping.
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
Simplifies the breastpump system by reducing the number of attachments, minimizing the risk of tube tangling and loss, and maintaining consistent suction levels during single or double pumping.
Implementation Method 1
The fourth port is sized and shaped to receive one of the first tube or the second tube and permit a predetermined amount of fluid to pass by way of a leakage path

AI summary
The connector of the present invention provides fewer connections and attachments to a breastpump configured for expressing breast milk from both of a woman's breasts simultaneously, thereby facilitating easier use of the breast pump and yielding fewer pieces for the user to carry or misplace. The connector includes a manifold with four ports. Individual tubes extend from three of the four ports and each has a plug member. One tube engages with a vacuum source and the remaining two tubes engage with a breastshield assembly for double breast pumping. When single breastpumping is desired, one of the two tubes connected to the breastpump assemblies is disconnected and engaged with the dock port of the manifold.
