Circuit Authentication TRIZ Cases
- Multi-Mode Battery Charging Circuit for Fast Charging Heat Control
A control module identifies power supply type and switches charging modes to speed charging while limiting battery heat.
- EV Power Transmission Interface for V2G Billing Authorization
Defined EV, supply equipment, and grid messages enable discharge scheduling, billing, and user authorization for V2G energy transfer.
- Earphone Box-Entry Detection Using Built-In Acoustic Signals
Using the earphone's own microphone, this case detects box entry from insertion sounds to avoid extra sensors, cost, and false judgments.
- Smart Outlet Authentication and Metering for Power Usage Billing
Integrated metering, relay control, and server authentication let outlets track charging power accurately for billing while blocking unauthorized use.
- Wall-Mounted Contactless Charging Station for Secure Device Management
A wall-mounted contactless charger uses angled slots, locking, and monitoring to charge multiple inmate devices without cords or floor carts.
- Wireless Charging Recovery for Fully Depleted Batteries
RF-powered boot charging uses ROM first, then shifts to RAM-based control so a fully depleted wireless charging battery can recover without interruption.
- Wireless Charging FOD Using Resonant Peak Frequency Feedback
Resonant peak frequency and quality-factor feedback improve foreign object detection in wireless charging, reducing heating, power waste, and damage.
- Charging Cabinet Contact Plates for Cordless Laptop Power
Conductive plate contacts replace cords and low-power induction, enabling automatic laptop charging, power control, and device tracking.
- Separate Authentication Module for ENDS Age Verification
A separate chip or circuit board adds age verification to aerosol delivery devices by controlling power or charging without PCB redesign.
- Wireless Charging Bay for Sterile Medical Device Batteries
A dual-antenna charging bay powers medical device batteries through a sterile barrier, avoiding contact oxidation and charge loss.
- Battery Charging Case Screening Assembly for Model Mismatch Sorting
A movable screening assembly sorts mismatched batteries in a charging case, reducing manual removal while preserving charging flow.
- Battery Pack Data Logging and GPS Tracking for Field Management
Built-in memory, GPS, and network communication let battery packs log performance, location, and handling data for easier tracking and maintenance.
- Battery Charger Voltage Negotiation for Stable Quick Charging
Dynamic voltage-current negotiation cuts quick-charge power loss and stabilizes battery charging with standard travel adapters.
- Replacement Battery Application Switching via Protocol Version Detection
Protocol version detection lets a replacement battery identify the host system and load the right control application, even in low-power mode.
- Earbud Case DC Voltage Control for Intermodulation Prevention
Capacitor-based insertion detection cuts radio power early, preventing intermodulation in earbud cases while managing DC bias levels.
- Contactless EV Charging Authorization Using Vehicle Image Recognition
Image recognition and position sensing let taxi charging pads admit authorized EVs, block unauthorized vehicles, and keep service available.
