Control Devices TRIZ Cases
- Powertrain Anti-Shuffle Control via Estimated Spring Displacement
A powertrain controller estimates damper spring displacement using rotational speed sensors to adjust engine torque and mitigate shuffle oscillations.
- Implantable Heart Pump Controller Synchronization
An implantable controller synchronizes pump speed with the cardiac cycle to generate physiological pulsatile flow.
- Integrated Shift Lever Mechanism for Vehicle Transmission
A single shift lever mechanism integrates gear shifting, drive force interruption, and differential lock control within a compact transmission assembly.
- Redundant Conductor Continuity Monitoring in Blood Pump Systems
A monitor detects electrical current changes in one conductor to verify the integrity of redundant power lines.
- Balancing Unit Pressure Control for Medical Fluids
A balancing unit uses a pressure-controlled conveying unit to maintain stable fluid flow in medical applications.
- Triple-shaft deflection gear for RWD vehicle floor height
A triple-shaft deflection gear with conical gearing connects the engine transmission to the Cardan shaft.
- Circulatory Support Controller Feedback Loop
A circulatory support controller adjusts blood pump speed using real-time sensor data.
- Intracorporeal Heart Device Two-Point Anchoring
A segmented intracorporeal device anchors across anatomical walls to distribute pressure and reduce tissue trauma during minimally invasive procedures.
- Dual Rotary Pump Artificial Heart Flow Balance
Independent pump speed control maintains physiological flow balance without atrial shunts, reducing device size.
- Saccular Cavopulmonary Assist Device Power Cavity
A saccular cavopulmonary assist device uses a dedicated power cavity to drive blood storage and flow.
- Vehicle Velocity Control Detecting Deviations Without External Sensors
Closed-loop vehicle velocity control analyzes movement status signals to detect deviations from predetermined threshold ranges.
- Cumulative Suction Detection in Implantable Blood Pumps
A control circuit calculates cumulative suction presence by dividing intervals with events by total time.
- Single-Piece Bearing for Four-Wheel Drive Shaft Alignment
A single-piece bearing design integrates guiding and supporting functions for power transmission shafts in four-wheel drive vehicles.
