Anti-Theft Devices TRIZ Cases
- Autonomous Vehicle Compartment Access Using Proximity Authentication
Two distance thresholds and user authentication let recipients locate and unlock the correct autonomous vehicle compartment while reducing theft.
- Vehicle Function Activation Using UWB Reflection-Corrected Presence Detection
UWB reflection analysis corrects portable-device ranging errors, enabling more reliable vehicle locking and unlocking near the car.
- Steering Shaft Clutch Switching Between Driving and Game Modes
A clutch between steering shaft sections disconnects road steering for game mode while preserving normal vehicle functions and wheel height adjustment.
- Door-Off Key Fob Search Using Occupant-Triggered RF Detection
Occupant and seatbelt status trigger periodic RF key searches when doors are removed, improving fob detection while limiting battery drain.
- Vehicle Biometric Handover With Delayed User Authorization
A timed biometric handover lets vehicle operation continue after one user exits while the next user's authorization is verified.
- Actuated Sensor Roof Height Switching for Clearance and Transport
A movable vehicle roof raises sensors above foliage and lowers for transport, balancing data acquisition, wind resistance, and storage.
- Parked Vehicle Cabin Sound Monitoring for Low-Power Occupant Alerts
A low-power head unit uses cabin sound classification to detect trapped occupants, send alerts, and help rescuers locate the vehicle.
- Vehicle Gesture Control for Position-Dependent Power Adjustment
Position-based gesture sensing lets one vehicle controller trigger different powered adjustments and functions with more intuitive, contactless operation.
- Predictive Vehicle Remote Start for Departure-Time Climate Readiness
Sensor-driven remote start uses vehicle state, location, and driver patterns to warm the cabin before departure while limiting fuel use.
- Vehicle Hatch Locking With Exterior Bypass and Auto Lock Control
Automatic hatch locking uses vehicle-state sensing to block interior opening in locked mode while preserving emergency exterior bypass access.
- Controller Light-Triggered Tamper Shutdown for Sealed Housings
A light detection circuit cuts controller operating voltage when housing opening admits excess light, blocking tampering and contamination.
- In-Cabin Occupant Authentication Using Liveness and Feature Matching
Combining face recognition, liveness checks, and in-cabin feature matching helps block spoofing from photos, video playback, and masks.
- OFN and Capacitive Touch Signal Integration for Multi-Standard Control
Combining OFN sensing with capacitive touch data simplifies multi-standard device integration and outputs unified control data.
- Vehicle Access Control Key Fob Low-Power Switching by Position
Position-based mode switching puts a vehicle access control key fob into low-power operation in low-use areas to extend battery life.
- Handleless Vehicle Door Entry Using Window Seal Sensors
A window-seal sensor and PEPS authentication open a vehicle door without external handles, preserving a smooth outer surface.
- Vehicle Request Arbitration Architecture for Expandable Device Control
A main manager with device-level sub-managers simplifies adding vehicle applications while keeping arbitration rules stable and control reliable.
- Motorcycle Parental Control via Bluetooth Parameter Access
Bluetooth access lets a supervisor view and modify motorcycle parameters remotely and trigger an automatic stop if distance limits or connection fail.
- Fold-Out Vehicle Seating With Authorized Access and Trunk Clearance
Authorized key or app commands and camera-based trunk checks let fold-out vehicle seating serve third parties without exposing stored items.
- Steering Lock Control Using Latch Circuits for ASIL-D Safety
Existing power and vehicle-state signals are latched to prevent erroneous steering lock activation without redundant controllers or added sensors.
- Electronic Lock Access via RFID Tag Intent and Decentralized Control
RFID tag intent signaling lets a user device map tags to lock IDs and request secure access without a central control system.
- Vehicle UWB Module Auto-Location Using Distance Ranging
Distance ranging lets identical vehicle UWB modules self-identify their installed positions, cutting connector variation and manufacturing cost.
- Remote Ignition Interrupter for Fleet Vehicle Start Control
Encrypted WAN ignition control lets one mobile app start or disable multiple vehicles with geofencing beyond key-fob range.
- Powered Running Board Alarm Control for Adaptive Theft Deterrence
Sensor-driven alarm logic moves powered running boards in repeated patterns to match theft activity levels and strengthen vehicle deterrence.
- Fuel Cell Power Supply Restriction After Working Machine Use
Network restriction requests let a fuel cell power supply cut or limit output after machine use ends, improving payment enforcement without mid-use shutdown.
- Vehicle Anti-Theft Authentication for Staged Function Activation
Multi-step authentication separates basic and driving functions to block unauthorized entry and vehicle startup in remote parking.
- Vehicle Entry Authorization Using Garage-Aware Intent Detection
Garage interior mapping and mobile device location prevent false vehicle unlocking, reducing theft risk and battery drain.
