Coolant Flow Control TRIZ Cases
- Linear Drive Nested in Vehicle Air Flap
Nesting a linear drive within the hollow interior of a vehicle air flap reduces installation volume and protects the mechanism from environmental exposure.
- Auxiliary EGR Cooler Circuit for Engine Adaptability
A parallel auxiliary circuit with an independent pump adds a low-pressure EGR cooler without modifying the main engine cooling configuration.
- Blower Scroll Housing Fastening via Interference Fit
Replacing threaded fasteners with an interference fit eliminates assembly tool requirements while maintaining secure attachment for the blower scroll housing.
- Thermostat Failure Detection Using Dual Temperature Thresholds
Dual temperature thresholds distinguish actual failures from radiator shutter effects, ensuring accurate engine water management.
- Electronic Fan Clutch Actuator with Nested Ferromagnetic Housing
Nested ferromagnetic housing concentrates magnetic flux to reduce unbalanced bearing load and simplify internal structure.
- Sequential Air Flap Actuation for Reliable Position Monitoring
Segmented coupling decouples air flaps at different times, allowing individual position monitoring through drive current analysis without complex sensors.
- Working Machine Cooling Control System PID Threshold Integral
A cooling control system adjusts fan rotation speed using a threshold-based integral activation mechanism.
- Blower Housing Ramped Surface Deflects Particulate Matter
Ramped duct surface deflects particulate matter toward an exhaust window, preventing filter clogging and extending component lifespan.
- Electric Vehicle Heat System Parallel Circuit Topology
Parallel heat exchanger circuit reduces construction complexity while maintaining independent cooling for multiple vehicle components.
- Aluminum Thermostat Housing Cooling Fins Crack Resistance
Cast aluminum thermostat housing with exterior cooling fins and tapered post resists thermal cycling cracks.
