Medical Devices TRIZ Cases
- Infusion Pump Motor Drive Sequence for Cogging Torque Reduction
A brief reverse windup before forward rotation cuts startup cogging torque in infusion pump motors, enabling smaller, lower-power pumps.
- Magnetic Line Holder Mounting for Sterile Dialysis Tube Positioning
Magnetic attachment lets dialysis fluid lines be repositioned securely on the machine housing while reducing contamination risk and torque damage.
- Infusion Pump Motor Drive Sequence for Cogging Torque Relief
A reverse-then-forward rotor drive sequence helps infusion pump motors overcome cogging torque with lower peak torque, power drain, and size.
- Lithotripsy Laser Parameter Control for Heterogeneous Stone Fragmentation
Adaptive laser settings for lithotripsy improve stone fragmentation by matching energy, pulse width, peak power, and frequency to stone properties.
- Transcutaneous Coil Loop Layout for Stronger Implant Coupling
A body-worn loop coil improves transcutaneous power and data coupling, shrinking the external unit and avoiding retention magnets and skin irritation.
- Endoscopic Laser Aiming Beam Control for Illumination Mode Visibility
Aiming beam wavelength switches with endoscope illumination mode to keep the spot visible and prevent treatment energy delivery when unseen.
- Analyte Sensor Pin Layout for Reliable Skin Penetration
Pins placed on the auxiliary-needle side make the substrate bend toward the skin, improving penetration reliability and detection accuracy.
- Integrated Battery Cavity for Miniaturized Analyte Detectors
By embedding the battery cavity into the transmitter shell, this case frees space for higher capacity and smaller analyte detectors.
- SMA Pump Actuation Control Using Resistance-Based Pulse Termination
Resistance, rate-of-change, and temperature feedback stop SMA actuation pulses earlier, cutting pump energy use and mechanical fatigue.
- Endoscopic Laser Aiming Beam Switching by Illumination Mode
A controller switches aiming beam wavelength by endoscope illumination mode to keep the beam visible and avoid unnecessary tissue energy delivery.
- Sealed Medical Fluid Transfer With Sensor-Guided Dosing
A sealed hose-and-pump setup uses destination sensing and connector flushing to dose medical fluids accurately while limiting leakage, vapor exposure, and waste.
- Endoscope Working Channel Unclogging With Flow-Sensed Irrigation Control
Flow sensing detects endoscope channel clogs and triggers irrigation or suction to clear them without harmful pressure swings at the anatomical site.
- Vehicle Sound Platform With NFT Marketplace and Cyber Sickness Mitigation
Biometric emotion modeling and sound masking help a vehicle metaverse platform personalize virtual sound trading while reducing cyber sickness.
- Dual-Voltage Aerosol Heater Control for Lower Power Use
Different processor voltages speed heater control while cutting charging-side power use, helping deliver more aerosol per charge.
- Atomizer Exchange Controller Using Voltage Ranges for Heater Detection
Non-overlapping voltage ranges let one circuit detect atomizer attachment and heater state, cutting cost while keeping aerosol heating stable.
