Flexible Member Pumps TRIZ Cases
- MEMS Micropump with Thin Film and Bulk Piezoelectric Actuation
Thin film and bulk piezoelectric actuators deflect a single membrane to manage valve seats, resolving backpressure control issues in medical micropumps.
- Motorized Pumpjack for Intermediate-Depth Aquifer Irrigation
A motorized pumpjack system uses reciprocating rods to raise water from intermediate-depth aquifers.
- Peristaltic Pump Hose Channels for Electrohydrodynamic Atomizer Nozzles
Dedicated hose channels in a peristaltic pump prevent nozzle clogging and maintain consistent fluid flow for reliable electrohydrodynamic atomization.
- Bellows Pump Shock Vibration Suppression via Elastic Space
An elastic space portion within the bellows assembly absorbs pressure spikes to suppress shock vibration without reducing discharge amount.
- Fluid Disc Pump Axial Oscillation Isolation
An isolator reduces dampening at the peripheral portion of a driven end wall, maintaining pressure oscillation amplitude for efficient fluid pumping.
- Diaphragm Pump Noise Reduction via Interconnected Air-Permeable Housings
Interconnected air-permeable housings route displaced gas between chambers, containing acoustic energy and preventing external noise emission.
- High Viscosity Pump Pneumatic Return for Accurate Dosing
Pneumatic actuation replaces mechanical springs to overcome viscous resistance, ensuring accurate dosing of high viscosity fluids.
- Fluidic Pulsation Attenuator with Steep Rolloff Slope
A fluidic pulsation attenuator combines resistor and capacitor devices to create a steep rolloff slope for rapid flow stabilization.
- Magnetic Pump Mechanism for Tire Pressure Maintenance
A magnetic pump mechanism actuates a diaphragm to compress air and maintain tire pressure.
