Fluid Parameter TRIZ Cases
- Acoustic Sensor Suction Device for Hemolysis Prevention
An acoustic wave sensor detects characteristic suction sounds to automatically adjust pump power and maintain optimal flow conditions.
- Variable Displacement Pump Control for Noise Suppression
A variable displacement pump control system switches to partial capacity operation based on drive source rotational speed and hydraulic oil temperature.
- Portable Pump Heat Dissipation and Segmentation
Segmented chambers and an aluminum housing dissipate heat from a brushless DC motor, enabling high pressure in a lightweight portable pump.
- Membrane Pump Drive Piston Dynamics for Blood Damage Reduction
Three-phase piston control optimizes pump performance while reducing blood damage risk by maintaining uniform fluid flow.
- Smooth Flow Control for Embedded Micropumps
Iterative learning control with optical feedback eliminates pulsatile spikes from pneumatic micropumps, enabling accurate in vivo biological condition mimicry.
