Fluid Parameter TRIZ Cases

A cryopump uses a non-combustible silica gel adsorbent to capture non-condensable gases within the vacuum chamber.

An electronic air pump integrates a magnetic on/off mechanism and an LED pressure display for precise sports ball inflation.

Variable fan speed and valve positioning via fuzzy logic prevent condensate formation while reducing energy consumption in oil injected compressors.

A self-priming pump system uses a bleed valve and controller to restore fluid prime automatically.

A suction booster assembly injects discharge fluid through a venturi passage to raise inlet pressure in reciprocating pump systems.

Detecting valve opening and closing times estimates gallery pressure, eliminating expensive transducers that reduce system reliability.

Removable pump head strain gauge transmits pressure data to compensate for barrel variations and ensure reliable nanoliter volume control.

A calibration system acquires pump pressure data across multiple current command values to generate precise control tables for variable capacity hydraulic pumps.

A compressor control unit adjusts operation stop pressure based on detected supply voltage levels to maintain efficient air storage.

Alternating constant pressure control between dual plunger pumps eliminates thermal effect pulsations and improves mobile phase composition reproducibility.

A gas compression system uses a pressure detector and regulator to maintain constant intake pressure, reducing engine gas consumption.

Extending the flow sensor shutdown delay to 1.5 minutes prevents electrical stress from frequent switching while eliminating pressure sensors.

Trial operations verify pump functionality in uncertain temperature ranges to expand the operational window.

A flow rate control valve slows pump switching to suppress upstream pressure pulsation.

Solenoid actuators regulate valve timing to prevent wear and heat buildup in reciprocating compressors.
