Arc-Shaped Heating Member for Breast Pump Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing breast pumps with heating functions often double heat breast milk, leading to nutrient loss, bacterial germination, and the production of harmful substances.
Innovation Solution
A breast pump design featuring a cover with an arc-shaped heating member, where most of the heating element is located in the upper area, reducing direct contact and heating of breast milk in the milk storage chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the arc-shaped heating member is positioned to heat the breast effectively, then the heating function is improved, but the breast milk in the milk storage chamber is overheated causing nutrient loss and bacterial growth
Solution Approach 1:
The heating member is designed with non-uniform heating distribution, concentrating heat in the upper area (first area) where the breast is positioned, while minimizing heat in the lower area (second area) where the milk storage chamber is located. This local differentiation of heating intensity allows effective breast heating while avoiding overheating of the breast milk.
Solution Approach 2:
The heating member is divided into different functional zones: a first area corresponding to the upper area of the cover body for heating the breast, and a second area corresponding to the lower area for minimal heating. This segmentation allows each zone to perform its specific function independently, resolving the contradiction between effective heating and avoiding milk overheating.
2Ease of operation
If the heating member is positioned to heat the breast, then use comfort is improved, but the breast milk contacts the heated cover and gets overheated
Solution Approach 1:
The heating member provides localized heating primarily in the upper area where the breast contacts the cover, while the lower area near the milk storage chamber receives minimal heat. This ensures comfort during use while maintaining breast milk quality by preventing overheating.
3Temperature
If the heating member heats the breast milk, then the breast milk temperature is improved for feeding, but excessive heating causes nutrient loss and harmful substance production
Solution Approach 1:
The heating member is designed to provide minimal heating in the lower area where the milk storage chamber is located, preventing excessive heating that would cause nutrient loss. The heating is concentrated in the upper area for breast comfort, while the milk temperature is maintained at a safe level.
Solution Approach 2:
The heating member is positioned and configured beforehand to minimize contact with the breast milk in the storage chamber. By pre-positioning the heating zones appropriately, the system prevents overheating before it occurs, preserving nutrient quality.
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
This design minimizes double heating of breast milk, reducing nutrient loss and bacterial growth, thereby maintaining the quality and safety of the breast milk.
Implementation Method 1
a trumpet cover (e.g., a horn cover) of the breast pump can fit the breast and hot compress the breast
Implementation Method 2
the breast milk in the breast pump is usually heated once before feeding the infant, thereby causing double heating of the breast milk

AI summary
Disclosed is a breast pump comprising a milk bin and a cover. The cover includes a cover body and an arc-shaped heating device. The cover body is connected with the milk bin, and the arc-shaped heating device is disposed in the cover body. The cover body comprises a lower area and an upper area separated by a wall. The lower area is connected to the upper area in a height direction of the breast pump, and the lower area and the milk bin form a milk storage chamber. A ratio of a height of the arc-shaped heating device in the upper area to a total height of the arc-shaped heating device is greater than or equal to 0.7 in the height direction of the breast pump.
