Breast Pump Rear Assembly Diaphragm Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current breast pumps are often uncomfortable to use and do not faithfully replicate the natural process of breastfeeding, with complex designs that require multiple parts to be dismantled for cleaning, making them inefficient and inconvenient.
Innovation Solution
A breast pump design featuring a rear assembly with a breast shield and flexible diaphragm that forms a unit with a milk container, easily disassembled for cleaning, and a front assembly with a power source, pump, and controller, allowing for simple assembly and disassembly, and incorporating a release element for secure coupling and alignment, reducing the number of components and improving user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a moveable diaphragm is used to prevent milk contamination and provide massaging action, then hygiene is improved and milk extraction is enhanced, but the device complexity increases and the number of parts to be dismantled for cleaning increases
Solution Approach 1:
The diaphragm is integrated with the breast shield to form a single unitary structure. The diaphragm forms part of the breast shield assembly, eliminating the need for separate diaphragm components that would require individual disassembly and cleaning. This merging reduces the number of parts while maintaining the hygiene benefits and milk extraction functionality.
2Reliability
If multiple parts are used in the breast pump assembly, then functionality and hygiene are improved, but the ease of operation deteriorates due to complex assembly and disassembly requirements for cleaning
Solution Approach 1:
The diaphragm and breast shield are merged into a single integrated assembly that can be detached as one unit from the main pump body. This reduces the number of separate components the user must disassemble for cleaning, improving ease of operation while maintaining full functionality through the integrated design.
3Productivity
If a complex multi-part design is used to achieve effective milk extraction and hygiene, then productivity is improved, but the loss of time increases due to time required for assembly and disassembly for cleaning
Solution Approach 1:
By integrating the diaphragm with the breast shield into a single removable assembly, the design reduces the total time required for disassembly and cleaning. Users only need to detach this one integrated unit from the main pump body for cleaning, rather than disassembling multiple separate components, thereby reducing time loss while maintaining milk extraction efficiency.
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 enhances user comfort by simulating the upper jaw movement of a baby during sucking, reduces the risk of leakage, and simplifies the assembly and cleaning process, making it easier to use and maintain while providing effective milk expression.
Implementation Method 1
a moveable membrane, known as a diaphragm, between the pump and the expression kit, the membrane forming a barrier against any milk being sucked into the pump
Implementation Method 2
a vacuum pump inside the breast pump generates a vacuum and the stimulation mode can be started
Implementation Method 3
the frame comprises a release element which projects along a channel in the front assembly, thereby to define a release actuator at an external surface of the front assembly for releasing the coupling together of the rear and front assemblies

AI summary
A breast pump or milk collection assembly comprises a rear assembly for fitting over the breast of a user, a front assembly for fitting over the rear assembly and a milk container for fitting beneath the rear and front assemblies. The rear assembly comprises all parts (other than the container) which will contact milk in use, such as a breast shield and a diaphragm. The front assembly comprises all parts which do not need cleaning, for example a cover for fitting over the diaphragm to define a sealed space between them, a power source, pump and controller, and a front cover. A release element which projects forwards along a channel in the front assembly, thereby to define a release actuator at an external face of the front assembly for releasing the coupling together of the rear and front assemblies.
