Propulsion Cooling TRIZ Cases
- Vehicle Heat Exchanger Airflow Flaps for Cooling Backup Paths
Dual flaps create independent airflow paths to the vehicle heat exchanger, preserving cooling if shutters fail while limiting drag.
- Grille Shutter Lamella Mounting for Easy Replacement
A mounting pin, C-shaped arm, and coupling link let grille shutter lamellas be installed and replaced without bending damage.
- Grille Shutter Fins With Collision Drop-Off for Cooling Airflow
A passive drop-off fin mechanism keeps grille opening area available during collisions, preserving vehicle cooling airflow without a center pillar.
- Passive PTO Cooling Through Axle Housing Heat Conduction
A passive heat-conducting path moves PTO heat into the axle chamber, improving stationary cooling without pumps, added complexity, or extra maintenance.
- Brake Duct Backflow Plate for Radiator and Brake Cooling
A backflow suppression plate in the brake duct redirects hot air away from the radiator while preserving brake cooling during travel.
- Grille Shutter Flap Alignment for Vehicle Front Surface Harmony
Rotating grille shutter flaps are arranged to follow the frame's rearward-extending front surface, improving visual harmony and reducing gaps.
- Active Air Intake Grille With Scissor Vanes for Airflow Control
Scissor-linked vanes open into an olive-shaped intake to boost airflow regulation and capacity without obstructing the grille appearance.
- Vehicle Grille Shutter Layout for Larger Opening Area
A single rotating shutter member opens a larger grille area while adapting to varied grille shapes with less structural complexity.
- Cooling Module Air Inlet Closure for Symmetric Airflow Control
Independent closing elements open paired air inlets symmetrically, improving cooling airflow control while reducing turbulence and fuel use.
- Ram Air Duct Layout for Cooling High Engine Bay Components
Fresh air from the grille is routed along the hood to the dash panel, cooling hard-to-reach engine bay components without water-cooled units.
- Vehicle Reservoir Tank Support for Coolant Level Stabilization
Predicted acceleration and dual-axis actuators tilt the reservoir tank to keep the coolant port submerged and block air bubbles in the cooling circuit.
- Foam Air Guide and Cooler Seal Layout for Vibration Decoupling
A foam air guide tensions an elastic cooler seal to improve airflow sealing while reducing vibration and noise in vehicle front-end cooling.
- Twisted Coiled Polymer Actuation for Lightweight Active Aero Modules
A twisted coiled polymer actuator replaces heavy DC motor units in active aero modules, cutting weight and cost while delivering vane motion.
- Air Intake Anti-Recirculation Channel With Water Extraction
A perpendicular overpressure wall and bottom drainage passage keep water away from the air intake while limiting airflow resistance.
- Vehicle Cooling Opening Cover With Elastic Airflow Control
An elastic connecting element opens a vehicle cooling cover on demand, improving airflow cooling while limiting drag and energy use.
- Rotating EV Radiator Assembly for Cab-Clear Service Access
A split stationary-rotating radiator assembly improves heavy-duty EV service access without cab interference or bulky actuation hardware.
- Vehicle Front End Module Splash Shield for Radiator Protection
A molded plastic splash shield placed between the heat exchanger and radiator blocks road splashes to prevent radiator wear and discoloration.
- Charge Air Cooler Grille with Deflecting Fins for Wheel Arch Cooling
A charge air cooler grille uses oriented fins to deflect cooling air and protect the heat exchanger from external debris.
