Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional valve structure is used in the breast milk collection device, then the device can perform negative pressure breastfeeding, but the valve is prone to deformation in long-term use and cannot provide good blocking effect, requiring frequent replacement
Solution Approach 1:
The patent employs a membrane with a negative pressure diaphragm and an annular one-way valve diaphragm that can be adjusted at different angles. This dynamic structure allows the membrane to adapt to deformation over time by repositioning the one-way valve diaphragm to maintain effective blocking, thereby extending service life while preserving reliability
Solution Approach 2:
The patent changes the angular parameter of the one-way valve diaphragm relative to the negative pressure diaphragm. By allowing angular adjustment, the system can compensate for deformation and maintain optimal blocking performance throughout the membrane's service life, resolving the contradiction between reliability and duration
2Duration of action of stationary object
If the membrane is designed with adjustable angle positioning, then the service life is extended and assembly is simplified, but the structure becomes more complex
Solution Approach 1:
The patent merges the negative pressure diaphragm and the one-way valve diaphragm into a single integrated membrane structure. This combination eliminates the need for separate adjustment mechanisms while maintaining the angular positioning capability, thus extending service life without significantly increasing device complexity
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 device extends the service life of the membrane, reduces user consumption costs, and ensures convenient assembly and operation by maintaining effective blocking and milk collection functionality.
Implementation Method 1
The one-way valve diaphragm is deformed and cannot provide a good blocking effect on the opening
Implementation Method 2
A negative pressure cavity is formed between the negative pressure diaphragm and the second shell

AI summary
The present invention introduces a breast milk collection device with a first shell, a second shell, and a membrane. The first shell has a milk suction passage and a milk accumulation chamber with an opening. The second shell is connected to the first shell and has a fixing seat. The membrane includes a negative pressure diaphragm and an annular one-way valve diaphragm connected to its outer edge. The membrane is adjustable, the negative pressure diaphragm tightly seals the milk suction passage, and the one-way valve diaphragm can block the opening. A negative pressure cavity forms between the negative pressure diaphragm and the second shell. The breast milk collection device features a durable, simple, and easily assembled one-way valve for efficient breast milk collection.
