Fluid Parameter TRIZ Cases
- Feed Forward Control for Diesel Exhaust Fluid Delivery Pressure Stability
Feed forward control predicts pressure disturbances from dosing requests to preemptively counteract negative spikes, maintaining stable system pressure.
- Variable Home Position Dispense Pump Reduces Hold-Up Volume
A dispense pump controller adjusts the diaphragm home position to match required fluid volume.
- Piston Compressor Variable Capacity Control via Electromagnetic Valve
An electromagnetic actuator holds a self-acting ring valve open in a piston compressor, resolving slow delivery rate response and throttling losses.
- Wheel-Mounted Air Compressor with Adjustable Support Legs
A wheel-mounted air compressor assembly uses length-adjustable support legs to mount securely on various vehicle wheels.
- Coolant Supply Device Pump Pressure Control
A coolant supply device adjusts pump rotation rate based on discharge pressure to deliver precise fluid flow.
- Inflatable Eyeglass Temple Cushion for Secure Fit
An inflatable cushion expands via an air pump to secure eyeglass temples, preventing slippage during movement.
- Fluid Control System Using Reservoir Pressure for Gas Displacement
A fluid control system uses a reservoir pressure sensor to determine gas displacement volume without inline flow sensors.
- Hydraulic Pump Drive Protection via Electronic Control
Centralized electronic control replaces autoclave cushioning to manage pump start-stop sequences, reducing drive damage from frequent cycling.
- Piston Pump Pressure Peak Detection for Flow Regularity
A piston pump uses a pressure sensor to measure metering chamber pressure peaks during compression cycles.
- Water Pump Unit Power-Saving Optimization via Switching Points
Parallel water pump units use working curves to identify optimal switching points, resolving inefficient energy consumption from undefined operation modes.
- Sensorless Pump Converter Using Affinity Equations
Affinity equations and numerical interpolation calculate instant pump parameters without physical sensors.
