Wearable Breast Pump Synchronization with Infant Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing breast pumps are often noisy, require frequent maintenance, and can be time-consuming and frustrating to use, with inadequate milk letdown and uncertainty about when milk production will resume, making it difficult for mothers to collect and store breast milk efficiently.
Innovation Solution
An article of clothing with an embedded breast pump that applies a customizable compression pattern and suction to facilitate lactation, including a collection mount, compression element, and reservoir, which collects and stores milk, and a system that synchronizes breast-pumping sessions with milk consumption based on temporal patterns of milk production and consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a breast pump is used to extract milk, then milk collection is enabled, but the device becomes noisy and requires frequent maintenance
Solution Approach 1:
The patent replaces traditional mechanical breast pump mechanisms with a biological approach - using the infant's own sucking action to extract milk. This eliminates the need for mechanical pumps, thereby removing noise generation and maintenance requirements while preserving milk collection capability
Solution Approach 2:
The patent introduces an intermediary device - a special bottle with a nipple that mimics the breast - which allows the infant to perform the extraction function. This intermediary transfers the milk extraction task from a mechanical pump to the infant's natural sucking mechanism, resolving the contradiction between effective milk collection and elimination of harmful factors
2Quantity of substance
If a mother manually operates a breast pump while holding her baby, then milk can be collected, but the process becomes time-consuming and frustrating
Solution Approach 1:
The patent enables the infant to perform the milk extraction service themselves by designing a bottle that allows the baby to suckle and extract milk from the mother's breast. This eliminates the need for the mother to manually operate a pump, significantly reducing the time and effort required while maintaining effective milk collection
Solution Approach 2:
Instead of the mother actively pumping milk while managing the baby, the patent inverts the approach by having the baby's natural sucking action perform the extraction. This role reversal eliminates the complexity of manual pump operation and reduces the overall time required for the process
3Productivity
If existing breast pumps apply pressure to facilitate milk letdown, then milk production is stimulated, but the pressure causes pain for the individual
Solution Approach 1:
The patent replaces mechanical compression devices with the infant's natural sucking action to stimulate milk production. The baby's suckling provides gentle, rhythmic stimulation that effectively triggers milk letdown without causing pain, eliminating the harmful effect while maintaining productivity
Solution Approach 2:
The patent changes the stimulation parameter from high-pressure mechanical compression to low-pressure rhythmic sucking. This parameter change maintains the ability to stimulate milk production while reducing the intensity to below pain thresholds, resolving the contradiction between effectiveness and comfort
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 solution reduces the noise and maintenance needs of breast pumps, enhances milk collection efficiency, and encourages longer-term breast pumping, improving user experience and providing health benefits for babies by ensuring a consistent milk supply.
Implementation Method 1
the pump may apply a pressure less than atmospheric pressure to a cavity between the areola and the inner surface of the collection mount
Implementation Method 2
the compression element applies a type of compression pattern at a location on the breast to facilitate lactation

AI summary
A system embodied in an article of clothing for synchronizing one or more breast-pumping sessions of an individual (such as a mother) and milk consumption by a second individual (such as a baby or infant) is described. In particular, based on measurements of a volume of the collected milk as a function of time and received information specifying milk consumption by the second individual as a function of time, a control circuit may determine a need for milk. Then, the control circuit may provide feedback based on the determined need for milk that synchronizes the one or more breast-pumping sessions and the milk consumption. For example, the feedback may alert the individual to initiate a breast-pumping session and/or may provide a signal to a breast pump that initiates a breast-pumping session.
