Electric Connection Testing TRIZ Cases
- Electronic Cigarette Control Chip Open and Short Circuit Protection
Control chip detects open and short circuits via current sampling, shutting down the driving module to prevent chip damage during assembly.
- Open Load Diagnosis Using In-Band Voltage Transients
A device applies in-band voltage transitions to measure signal line load resistance via time constant analysis.
- Capacitive Circuit Connection Loss Detection via Pulsed Signal Analysis
Evaluating circuit analyzes discharge curve changes in pulsed signals to detect connection loss in capacitive parts, avoiding DC current limitations.
- Moisture Detection Circuit for Electrical Connector Impedance Monitoring
A moisture detection circuit monitors impedance changes between electrical contacts to identify liquid presence on exposed connector surfaces.
- Cable Connection Quality Assessment via Impulse Response Echo Power
A test system transforms cable transfer functions into impulse responses to identify relative echo power for objective quality evaluation.
- Adapter Cable With Memory For Switching System Test Configuration
Adapter cable memory stores configuration data for test device to configure signal interfaces, eliminating manual parameterization errors.
- Connector Defect Detection via Voltage Sensing
Voltage sensing at connection pins detects moisture or corrosion defects, preventing connector malfunction.
- Contactless Magnetic Field Sensor for Inaccessible Circuit Testing
Surface coil generates magnetic field equivalent to coaxial loop, enabling non-destructive fault detection in inaccessible multilayer PCB regions.
