Control Devices TRIZ Cases
- Implantable VAD Controller Using Accelerometer for Dynamic Flow Adjustment
An implantable blood pump controller adjusts speed via accelerometer data to maintain flow during activity changes while reducing power consumption.
- AWD Engagement Control via Preliminary Engine Power Increase
An electronic control unit increases engine power before engaging the all-wheel drive coupling to transfer torque smoothly.
- Implantable Controller System with Percutaneous Connector for Power Management
A percutaneous connector enables direct contact charging to resolve slow recharging times and extend battery lifetime in implanted circulatory assist devices.
- Axial Flow Pump Speed Control for Pressure-Flow Simulation
Adjusting motor speed in axial flow pumps to simulate target pressure-flow characteristics.
- Biocompatible Roller Blood Pump with Compliance Chamber
A biocompatible roller blood pump uses a compliance chamber to buffer pressure fluctuations and maintain optimal flow efficiency.
- Autonomous Vehicle Drive Mode Selection for Off-Road Control
A control system selects operating modes to manage vehicle speed and transmission gear ratios.
- Vehicle Control Allocation for Path Tracking During EPS Failure
A control allocation system manages redundant actuators to guide a vehicle along a planned path.
- Cardiac Support Device Synchronization with Heart Strain Profile
A cardiac support device applies dynamic external forces to match the heart's natural ventricular strain profile.
- Vehicle Control System Fuel Cut-Off Threshold Adjustment
A vehicle control system adjusts fuel cut-off thresholds to terminate engine braking earlier during autonomous driving.
- Renal Flow Modifiers for Transrenal Pressure Gradient
Flow modifiers increase renal artery pressure and decrease renal vein pressure to create a transrenal pressure gradient.
- Biomimetic Actuation Device with Soft Pneumatic Muscles
Helical soft pneumatic artificial muscles replicate twisting cardiac motion while eliminating tissue trauma and friction at the epicardium interface.
- Four-Chamber Redundant-Impeller Artificial Heart Design
Segmenting the pump into four redundant chambers and merging control electronics eliminates invasive external components while ensuring reliable blood flow.
