Flexible Member Pumps TRIZ Cases

Closed-loop feedback control adjusts rotor position to maintain 2-5 per thousand tolerance, eliminating waste from inaccurate dosing.

A linear peristaltic pump cartridge integrates deformable material to create pulsatile fluid flow within a compact reagent reservoir.

A low-cost ambulatory medical pump uses a software-enforced service life limit to prevent reuse after safe operating limits are exceeded.

Variable roller speeds in a two-stage peristaltic pump stabilize output pressure, reducing tubing wear and maintenance costs.

Replacing bulky fans with ultrasonic vibrations eliminates mechanical noise while maintaining airflow speed and heat dissipation efficiency.

Hollow fiber membranes separate oxygen from ambient air while a piezoelectric pump moves the gas, alleviating low oxygen concentration effects.

A spring-loaded pump actuator moves liquid through sealed orifices to dispense concentrated solutions from a compact basin reservoir.

A retractable platform assembly resolves the contradiction between trailer stability and maintenance safety by providing a secure working surface for personnel.

A piston pump mechanism delivers fluid by cyclically alternating velocity to simulate natural heart function.

Staggered hydraulic drive synchronizes reciprocating strokes across multiple positive displacement pumps to maintain continuous flow.

Replacing rigid scrolls with a flexible membrane eliminates tip seals and gas leakage, lowering manufacturing costs while extending pump lifetime.

Deformable elastomeric pump ring creates tight seals, preventing internal and external fluid leaks.

Snap-fitting holder device guides tubing into fixed length and angle, resolving manual alignment errors that cause inconsistent fluid flow.

A micropump design uses a rotor shaft port overlapping inlet and outlet angles to pump fluid without valve seals.
