Anti-Theft Devices TRIZ Cases

Combining GPS, ignition status, and onboard sensor data enables faster carjacking detection and automatic alerts to drivers or authorities.

Priority-based UWB ranging resolves timing overlap between smart and digital keys, protecting smart key reliability without repeated skips.

A single in-cabin camera captures both door-side interior and exterior views, enabling pre-entry face authentication without extra exterior cameras.

BLE time-of-flight distance checks keep the authorized device near the vehicle, blocking relay-based unlocking and ignition.

An electromagnet-driven retention pin vibrates the door handle to signal authentication status while preserving emergency mechanical unlocking.

A trained model tracks body-part entry and displacement direction to cut false door-control triggers with lower calculation load.

Integrating touch, proximity, and NFC sensing into car sealings enables handle-free keyless access with cleaner styling and simpler assembly.

Remote authorization controls trailer coupling, air brakes, landing gear, and door locks to block unauthorized towing without physical keys.

State-based communication monitoring compares incoming data with normal lists to catch unauthorized signals during rapid onboard transitions.

A control lever with an integrated locking arm blocks misaligned locking bolts from unauthorized release by magnets or impacts.

Preset-pattern verification blocks powertrain startup in steer-by-wire control when controller communication appears unauthentic.

Sensors and gesture recognition let one operator control vehicle actions beside the vehicle, avoiding reboarding while maintaining reliable control.

Camera-based gesture recognition lets one ground operator guide and control a vehicle without re-boarding or onboard input devices.

Dual vehicle authentication combines RF key detection with badge or NFC credential validation to block unauthorized access in fleets and dealerships.

An external sensor tracks exhaust vibration patterns from cutting tools and triggers alarms or wireless alerts before catalytic converter theft succeeds.

Secondary user access is verified through stored identity data and owner confirmation, balancing autonomous vehicle security with flexible use.

A lockable housing blocks access to the gear shifter release and secures the steering wheel, keeping a stolen vehicle stuck in park.

Image, voiceprint, and torso detection identify a child left alone in a vehicle and trigger alerts, child locks, and temperature control.

When no delivery person is inside a stopped autonomous delivery vehicle, monitoring is reduced to cut remote workload and data processing.

A delayed alarm and tracking approach helps deter carjackers, protect occupants, and improve vehicle recovery without provoking immediate violence.

Structured UWB sessions with adaptive schedule blocks cut standby power while preserving multi-smartphone ranging success.

A dual-wireless vehicle key links the car and a smartphone app to simplify secure access without dedicated onboard access hardware.

Multiple vehicle sensors form overlapping distance regions to locate an unlocking device more accurately despite measurement errors and relay attacks.

Driving behavior data enables in-vehicle identity checks that avoid interrupting the driver while improving authentication stability and accuracy.

Camera-based facial analysis detects driver health events in real time, triggering alerts and vehicle safety protocols to reduce crash risk.

BLE and UWB key authentication lets a vehicle prioritize multiple digital keys for secure remote control of comfort functions.

Multiple vehicle sensors use time-of-flight distance regions and overlap points to locate an unlocking device more accurately and resist relay attacks.

Nesting the worm and rod inside the main gear cuts steering lock package size while preserving reduction ratio and unlocking force.

Vehicle state signals trigger early controller and camera startup, cutting display delay without higher controller cost or wasted processing capacity.

Driver verification allows temporary steering for emergency vehicle movement, then actuator torque blocks steering after a set distance to deter theft.

A wireless latching relay disconnects vehicle battery power to block relay attacks and key theft while simplifying fleet anti-theft installation.

UWB reflective sensing replaces capacitive vehicle access sensors to cut false activations from humidity, snow, and metal coatings.

A gateway and firewall isolate critical RV controls from accessory bus interference while preserving secure diagnostics and reliable data flow.

A unified encrypted valet keycode enables vehicle entry and drive-away authorization while keeping passive entry and secure idle compatible.

Vibration sensing and RSSI-based module activation cut unnecessary vehicle key communication, extending remote battery life.

A start-button fingerprint sensor replaces manual ID entry and prioritizes in-vehicle service authentication alongside engine start.

Combining time-of-flight and phase shift cuts switching and power use while keeping wireless distance measurements accurate.

Remote confidence confirmation and fallback biometrics help vehicle access systems handle sensor and environment differences more accurately.

Combining key fob detection with camera or radar intent sensing helps a handleless vehicle door avoid accidental opening near passersby.
