Milking Pump TRIZ Cases

A three-way connecting assembly with an elastic valve plate attached to the milk outlet reduces flow resistance in wearable breast pumps.

Segmenting the actuator from the interface resolves size and efficiency trade-offs while enabling mobile communication.

Segmenting suction and milk flow paths isolates the vacuum cylinder, reducing noise while preventing milk contamination in the pump.

A breast fluid collection pad uses negative pressure to gather fluid from the nipple.

A breast shield with an adhesive inner surface attaches directly to the body, enabling hands-free milk expression without external support structures.

An absolute pressure sensor measures atmospheric data to adjust operating parameters in a breastmilk expression system.

A rolling diaphragm pump moves between vent and vacuum orientations to create rapid pressure changes in the chamber.

Segmenting the wearable flange from the pump unit resolves mobility constraints while maintaining efficient milk extraction.

A motorized breast pump head isolates drive mechanism vibration via a resiliently deformable member, reducing noise and enhancing user comfort.

Elongate inflatable bladder deforms to apply peristaltic action to user teat within breast pump funnel assembly.

Layered flat-hose assemblies prevent kinking and patient discomfort while maintaining an airtight seal for continuous exudate flow.
