Anti-Theft Devices TRIZ Cases

Rear cameras and orientation sensing keep a simulated rearview mirror aligned with driver view, improving visibility beyond rear deck obstructions.

Sensors track a person near a partially opened rear door and trigger audible or visual alerts before head contact occurs.

Separate interior and exterior time-of-flight sensing improves key location accuracy in reflective spaces, preventing incorrect locking or start decisions.

A movable locking element and evasive support relieve tilting loads in vehicle locking housings, preventing damage while preserving lock stability.

Position-based mobile authentication unlocks vehicle safety functions within a target distance, removing separate LF keyless entry hardware.

Switched UWB antennas combine TWR angle finding and anchor triangulation to improve vehicle smart-key positioning near metal surfaces.

An external contact and emergency power algorithm unlock vehicle doors with depleted batteries by disabling non-essential functions and limiting current.

NFC or Bluetooth authentication lets a fuel cell vehicle safely supply external power without driver entry, expanding mobile power use.

A self-centering sensor module layout simplifies vehicle door handle assembly, saves installation space, and removes the need for a handle recess.

Advance cabin notices and power-state-triggered retransmission help prevent unexpected vehicle start lockout while preserving contract enforcement.

Wireless mobile ID authentication detects vehicle movement without any registered user nearby, helping stop tow-away theft in shared-use vehicles.

A touch-sensing outer cover combines rear camera and trunk release functions to cut parts, simplify assembly, and free tailgate design.

Asset-mounted collectors and stored user records enable secure temporary equipment access and real-time status monitoring across sites.

Delayed audible alarms combined with immediate tracking signals and image capture help deter hijackers while reducing violent reaction risk.

Remote document and code-based driver verification enables secure vehicle access for test drives without in-person checks or excess personal data.

After door locking, movement or radio-wave changes from a digital key smartphone are checked before an alarm warns it may be left in the vehicle.

A body-mounted winch keeps the transport vehicle door under tension after lock tampering, blocking interior access and reducing theft risk.

A pressure-sensed cover and magnetic lock protect vehicle image sensors from tampering while allowing authenticated maintenance access.

Dual input on the vehicle and portable terminal enables automatic authentication while resisting relay attacks and avoiding manual entry.

An NFC-powered backup unlock path transfers external energy to a keyless door latch when onboard power is unavailable.

A vehicle processor maintains or ends external camera sessions based on identifying image data, enabling real-time theft monitoring.

A deformable handle surface replaces moisture-prone capacitive touch sensing while integrating RF antennas for reliable keyless entry and object detection.

Multi-step NFC authentication replaces bulky keys with whitelist, token, and secret-key checks for secure, selection-free vehicle control.

Updated fraud detection rules let vehicle ECUs adapt to new malicious frames while applying changes only when network conditions allow.

A spline-locking ring fixes the wheel hub to the axle, while a covered lock blocks unauthorized removal without bulky actuators.

Handle sensors authenticate users from hand pressure and grip dynamics, avoiding radio key theft and spoofable visual biometrics.

Dynamic Bluetooth threshold spacing reduces false vehicle lock and unlock triggers caused by signal blocking and unstable proximity detection.

A drivetrain-mounted locking pawl immobilizes the driveshaft when ignition is off, blocking tampering, driving, and towing.

A bolt-through-sprocket lock stops tracked machinery in both directions while staying lightweight, durable, and quick to install.

Repeated powered door lock movement creates a threat-responsive alarm pattern that deters theft without keeping maximum system complexity active.

Biometric data captured before arrival lets a station determine identity early and begin credential or system actions before the person arrives.

Cloud-managed vehicle e-keys enforce time, location, and speed limits while securely sharing access and applying personalized settings.

Adaptive Bluetooth unlock and lock thresholds create a buffer against signal blocking, reducing false vehicle access triggers.

Encrypted Bluetooth plus an RFID security card blocks relay attacks by requiring both verified signals and close-range car access.

Dual-protocol authentication links a rider’s phone to an autonomous vehicle for secure cabin unlocking and remote cabin setting control.

Fleet incident data is matched to vehicle state to score cyberattack risk and selectively restrict exposed functions before damage occurs.

A sealed retrofit-ready handle module adds wireless access control while protecting electronics from weather and reducing assembly effort.

Separate inner and outer touch zones let users intuitively open or close a vehicle door without mechanical handles or confusing controls.

Motion sensors, cameras, a microphone, and a remote speaker combine to deter vehicle theft with live warnings and recorded evidence.

When the driver cannot operate the vehicle, passenger voice commands are enabled through driver-state detection to support safe deceleration or steering.

A spring-loaded vehicle alert deploys a visible display, camera, and emergency communication to help victims notify others under duress.

Periodic event monitoring enables seamless vehicle mode switching by updating operating state in real time without parking or timer delays.

A backup-powered emergency actuator authenticates a transponder and unlocks a vehicle door or tailgate when the main electrical system is dead.

Gesture-based door opening is gated by face authentication, allowing registered users convenient access while blocking unauthorized entry.

Counter-torque from the feedback actuator resists free steering wheel movement after ignition-off until the next lock position engages.
