Electric Devices TRIZ Cases
- Battery Cell Vent Deformation Detection for Pre-Venting Response
A spaced detector tracks battery cell vent deformation against a threshold, enabling action before hazardous discharge without impairing vent function.
- Battery Undertray Sensor Textile for Intrusion Detection
Conductive sensor wires embedded in an EV battery undertray detect deformation from below impacts, enabling early intrusion warning.
- Structural Battery Cooling Channels for EV Pack Rigidity
Integrated cooling ducts in the front beam and battery modules improve EV pack cooling, rigidity, and NVH without reducing cell volume.
- Vehicle EST Fault Override Using Model-Based Parameter Estimation
Model-based estimation replaces faulty EST condition parameters so vehicle energy systems stay operable in hazardous situations.
- Standby Power Supply Monitoring for Rail Vehicle DC Networks
Independent monitoring of converter voltage, backup output, and stored energy enables fast fault detection and emergency action in rail vehicles.
- Fuel Cell Stack Sensor for Hydrogen Leak and VOC Poisoning Detection
Multi-substrate sensing compares internal and external temperature, humidity, and hydrogen data to detect leaks and VOC poisoning.
- EV Motor Inverter Counter-Torque Battery Diagnosis
Opposing torque from dual inverters lets the EV motor discharge the battery for deterioration diagnosis without a separate load device.
- EV Chassis Collision Structure for Guided Battery Pack Protection
Guided chassis deformation uses energy-absorbing boxes and bottom fenders to protect EV battery packs during collisions.
- Scooter Motor Stator Winding Temperature Sensing for Overheat Protection
A bimetallic sensor placed near the stator winding improves overheat detection stability and lets the controller limit or stop motor power.
- MSD-Mounted Contactor Retrofit for Certified Battery Packs
Replace a manual service disconnect with a contactor in the same battery-pack cavity to add remote HV control without major redesign.
- Motor-Inverter Mount Layout for Frontal Collision Protection
A rotatable motor mount moves the inverter upward and rearward in a frontal crash to avoid contact, reduce damage, and limit electrical leakage.
- EV High-Voltage Module Fuse Box Layout for Non-Invasive Service
A separate fuse-box enclosure lets EV high-voltage modules replace fuses without opening the main electronics housing or compromising EMC.
- Heavy-Duty EV Battery Mounting With Vibration Isolation and Sealing
A modular battery mounting layout uses isolators and load members to cut frame vibration while limiting moisture exposure in heavy-duty EVs.
- Terminal Temperature Sensing in Electrical Assemblies for Fault Protection
Passive terminal temperature sensing triggers controller status changes to detect overcurrent and prevent overheating without complex polling.
- Electric Lawn Mower Drive Control With Emergency Motor Braking
Independent wheel motors and controller-managed shaft brakes improve mower maneuverability, blade control, and emergency stopping.
