Propulsion Using Engine-Driven Generators TRIZ Cases
- Automotive Thermal Unit Valve Layout for Hybrid HVAC Integration
A switchable hot/cold hydraulic loop improves cabin and engine temperature control while reducing refrigerant use in hybrid and electric vehicles.
- Hybrid Paving Machine Powertrain for Low-Emission Hydraulic Drive
A diesel-battery powertrain shifts paving machine actuators to hydraulic and electric drive, cutting emissions without losing operating performance.
- Dual-Motor Main Rotor Anti-Torque Control for Aircraft Yaw
Counter-rotating motors at the main rotor hub replace the tail rotor to improve yaw control while reducing noise, complexity, and safety risks.
- Hybrid-Electric Aircraft Propulsion for Uncommanded Thrust Loss
Electrical power is added to the turbomachine and propulsor after uncommanded thrust loss, helping maintain aircraft control and performance.
- Rail Vehicle Power Unit Control for Standby Engine Preheating
Temperature-based control keeps standby rail power engines warm through shared cooling circuits, cutting cold starts, energy use, and wear.
- Moving-Object Power Supply Control Using Predicted SOC
Predicted SOC correction lets a moving object's generator respond early to load swings, avoiding storage depletion and power shortfalls.
- Generator Cradle Mount With Vibration Isolators for Vehicles
Vibration isolators in a cradle mount keep an onboard generator stable while reducing noise, discomfort, and component damage in vehicles.
- Vehicle Parameter Feedback Control for Primary Mover Health
Closed-loop control uses predicted and actual primary mover performance to set vehicle parameters that improve fuel efficiency while preserving vehicle health.
- Dual-Channel Aircraft AC Power Sharing for Fault-Tolerant Operation
Bidirectional converters link dual AC channels so one engine-driven machine can support the other during faults and load transitions.
- On-Board EV Generator With Manual Pneumatic Start Assist
A two-lever pneumatic start cycle drives a magneto generator, letting an EV generate onboard power without batteries or charging stations.
- Chainless Hybrid E-Bike Powertrain Without Chain Maintenance
A pedal-driven generator and motor replace chains and chainrings, avoiding chain drop, clothing entanglement, and routine drivetrain upkeep.
- Serial Hybrid Rail Work Vehicle for Engine-Off Hydraulic Operation
An electric motor drives the hydraulic pump with the engine off, enabling quieter, emission-free rail work equipment operation.
- Engine-Driven DC Supply Layout for Flexible Load Integration
A modular housing layout separates precharge, DC-DC, and communication functions to fit varied external loads without overlap.
- EV Powertrain Controller for Load Bank Cooling Integration
A unified EV controller uses the compressor to cool a resistive load bank, reducing frontal cooling area and freeing mounting space.
- Vehicle Battery Current Threshold Control for Degradation Limiting
Dynamic current threshold adjustment limits battery degradation during sustained high-load periods while preserving usable vehicle battery performance.
