Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional breast pumping devices use multiple components, then the device can perform pumping function, but the structure becomes complicated and size increases
Solution Approach 1:
The patent combines multiple functional components (pumping unit, collection bag, stop valve unit) into a single integrated device made from one piece of elastomeric material. The pumping unit with concaved ends, the collection bag, and the stop valve unit are all formed as one unified structure, eliminating the need for separate parts and reducing overall device complexity and size.
Solution Approach 2:
The single elastomeric material structure serves multiple functions simultaneously: the concaved ends create vacuum for pumping, the central portion forms the collection bag, and the integrated stop valve unit controls flow. This multi-functional design eliminates the need for separate components while maintaining all necessary pumping functions.
2Ease of operation
If conventional breast pumping devices have multiple components, then the device can be assembled, but it becomes difficult to disassemble for cleaning
Solution Approach 1:
By merging all components into a single elastomeric material structure, the device becomes non-assembled and thus non-disassemblable in the traditional sense. The entire device including pumping chambers, collection bag, and valve mechanisms can be cleaned as one piece by rinsing with water, eliminating cleaning difficulties associated with multiple separate components.
3Ease of operation
If the device is made from single material, then cleaning becomes easy, but manufacturing precision may be affected
Solution Approach 1:
The patent utilizes the elastic properties and memory characteristics of elastomeric materials to achieve precise structural formation through molding processes. The material's ability to return to original shape and maintain consistent deformation allows for precise pumping chambers and valve mechanisms to be formed directly in the molding process, maintaining manufacturing precision despite using a single material.

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 integrated design enhances user convenience by simplifying cleaning and reducing the device's size, making it easier to use discreetly and hygienically.
Implementation Method 1
when an internal gas of the controlling portion and the engaging portion is extracted by an external device, the one end of primary unit is shifted toward the inside of the engaging portion and drives the squeezing unit to generate a contraction
Implementation Method 2
when the controlling portion and the inside of the engaging portion are pressure-released by an external device to supply gas, the one end of primary unit is shifted toward an outside of the engaging portion and drives the squeezing unit to generate an expansion
