Anti-Theft Devices TRIZ Cases

A portable device configures verified radar gestures for contactless vehicle flap or door adjustment without physical access to the vehicle.

Spikes mounted on inner and outer tire beams puncture the tire on rotation, stopping trailer movement when force defeats standard locks.

Occupant detection overrides key lock-out prevention after automatic stop, locking an evacuated vehicle even when the key remains inside.

Conductive bolts form an electrical loop that detects rim or frame removal accurately and avoids wind- or vibration-driven false alarms.

Timing pre-derived URSK generation by digital key location avoids Secure Element conflicts and reduces vehicle start or unlock delays.

Vehicle-stored update data lets smart keys update wirelessly based on key presence and count, reducing service visits, cost, and downtime.

Exterior logo buttons replace separate vehicle access controls, cutting components, weight, and drag while enabling sequence-based functions.

Authenticated user profiles store language and machine settings so non-owner operators can start work quickly without unauthorized changes.

A protrusion-backed deflectable wall turns badge press force into a reliable sensor signal for secure motor vehicle closure access.

Semiconductor switching and concealed CAN-bus plus analog-line integration make vehicle immobilization harder to detect, bypass, or disable.

Outside-vehicle voice recognition replaces leg-trigger sensors to open liftgates and personalize vehicle settings without limb use.

A vehicle combines RF, magnetic sensing, and machine learning to locate a phone or wearable for secure passive entry without a bulky key fob.

A single UWB radar detects approach, face orientation, and line of sight to trigger vehicle door access without added cameras.

Optical monitoring and scatter-based fingerprinting detect drilling or housing entry without compromising the sealed vehicle module.

When a key fob is missing, secondary authentication via phone, code, or biometrics enables secure vehicle restart without stranding occupants.

Position-based mode switching cuts key fob wireless activity in low-use areas, reducing power draw and extending battery life.

Adaptive UWB presence sensing wakes the camera only near the vehicle, cutting power use and shortening hands-free door unlocking delay.

Combining UWB communication with backscatter radar improves object position and trajectory accuracy around vehicles for earlier system activation.

A cloud-mediated unlock check removes fob-vehicle code synchronization, blocking Rolljam replay and DoS attacks in vehicle entry.

Selective attestation verifies only the first unverified vehicle digital key, cutting NFC authentication data, time, and energy use.

Earhole acoustic reflection adds user verification to wireless vehicle control, reducing unauthorized operation within a wider range.

Historical vehicle movement defines a permitted remote-control area, blocking commands when the car is outside authorized use patterns.

A controller simplifies EV power modes using button, brake, and timeout logic to reduce user confusion and prevent battery overconsumption.

Wireless padlock control lets cargo authorities verify and unlock trailer doors remotely while tracking location and reducing unloading delays.

Serrated nut and sleeve collar surfaces lock battery clamp preload against vibration, reducing loosening, noise, and battery movement.

GPS, MCC, and quadtree-based location checks let vehicles immobilize only in authorized areas while reducing false positives from jamming.

Dual-mode authentication switches between simple and common checks to cut vehicle Bluetooth key connection delay without losing security.

Image sensors and an ECU detect an authorized user and carried objects to open the right vehicle closure hands-free.

On-site wheel immobilization uses a keypad-locked boot and lug nut blocking plate to avoid towing delays and enforcement cost.

Up-sampling and cross-correlation improve PEPS time-of-arrival ranging, helping vehicles detect relayed key fob signals and block unauthorized entry.
