Wearable Breast Pump Internal Channel Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current breast pumps require frequent disassembly for cleaning, which is labor-intensive and inconvenient, due to their independent structure components.
Innovation Solution
A wearable breast pump design that integrates a host machine with a detachable cup and flowing channel unit, featuring a variable pressure chamber for simulating a sucking action, allowing for easy demounting and cleaning by housing the flowing channel unit inside the cup, reducing occupied space and improving integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the breast pump components are designed as independent structures, then each component can be cleaned separately, but the device requires frequent disassembly which increases labor and reduces convenience
Solution Approach 1:
The patent integrates the flowing channel unit directly into the cup structure, forming an integrated assembly that eliminates the need for separate disassembly of channel components. The flowing channel unit includes inlet and outlet channels that are permanently attached to the cup, allowing the entire assembly to be removed and cleaned as a single unit, thereby reducing labor while maintaining cleanability
2Device complexity
If the flowing channel unit is integrated inside the cup, then the structure is simplified and space is reduced, but the detachability for cleaning may be compromised
Solution Approach 1:
The patent divides the breast pump into two main detachable segments: the host machine and the cup assembly. The flowing channel unit is integrated within the cup segment, which can be completely detached from the host machine. This segmentation allows the complex integrated structure to maintain ease of operation through simple two-part detachment for cleaning purposes
3Ease of operation
If the cup is detachably connected to the host machine, then cleaning becomes easier, but the structure becomes more complex with multiple connection points
Solution Approach 1:
The patent combines the flowing channel unit with the cup structure, eliminating separate channel assemblies and their associated connections. This merging reduces the number of connection points needed - only the cup needs to detach from the host machine, rather than multiple separate components requiring individual detachment, thereby simplifying the overall connection structure while maintaining cleaning ease

AI summary
The present disclosure provides a wearable breast pump, including a host machine, a cup and a flowing channel unit. The host machine includes a variable pressure chamber. The cup is detachably connected to the host machine through the variable pressure chamber. The flowing channel unit is detachably arranged inside the cup and separates an internal space of the cup into a flowing channel and a milk storage bowl. The flowing channel is communicated with the variable pressure chamber, the milk storage bowl and the outside. The wearable breast pump has the flowing channel unit arranged inside the cup, achieving structural optimization, whereby making the structure more concise and the shape more beautiful, as well as increasing the integration level and reducing the occupied space.
