Anti-Theft Devices TRIZ Cases

Successful user-terminal history raises the biometric threshold to cut false acceptance while preserving access for less-established users.

Foam-encapsulated actuation and gesture sensors make vehicle door handles compact, moisture-resistant, and less prone to false triggering.

Capacitive touch, radar, and ECU control enable seamless vehicle entry while blocking automatic door opening when obstacles are in the swing path.

A wristwatch terminal uses low-frequency wake-up signals and adaptive authentication to enable low-power vehicle start, access, and tracking.

Motion-based door unlocking lets authorized users admit unregistered passengers while preserving vehicle security through interior and exterior image recognition.

A vehicle searches for a registered mobile terminal before boarding so user settings can be applied early with lower power use.

Multiple wireless receivers and localization modules combine BLE, UWB, Wi-Fi, or cellular signals to improve vehicle access accuracy across regions.

A radially expanding center-bolt lock fits different wheel bores and blocks access to wheel nuts to resist unauthorized removal.

A hidden controller cuts power to the shift interlock solenoid, keeping an idling vehicle locked in park against unauthorized shifting.

Signal strength consistency checks between a portable key and multiple vehicle transceivers help block relay attacks without sacrificing keyless entry convenience.

State checks run only after a connection request, cutting mobile terminal power use while preserving authentication security.

An integrated actuator, hinge, and lock lets delivery robots open compartments automatically while keeping items secure during navigation.

Baseline noise tracking and threshold timing help a vehicle liftgate ignore sensor spikes and avoid unintended hands-free activation.

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

Contactless NFC or Bluetooth authentication lets a fuel cell vehicle safely power external loads without driver entry.

A unified test API automates digital key validation across devices and vehicle models, cutting manual effort, errors, and test time.

Image-based buyer verification and wireless settlement unlock a vehicle trunk only for registered purchasers, reducing theft and store setup cost.

An ultrasonic fingerprint assembly under the dashboard enables keyless mobile carrier access and user-specific function settings.

BLE beacon authentication replaces complex bidirectional access control, cutting energy use and system cost while keeping secure, user-friendly entry.

OBD and sensor data are combined with facial and gesture analysis to verify drivers, detect vehicle faults, and deliver in-vehicle recommendations.

Wireless network authentication verifies an autonomous vehicle at the correct pickup or drop-off point when GPS alone is not precise enough.

Mobile-based user identification loads private driver settings and switches shared entertainment preferences as occupants change.

Adaptive radar narrows near a coupled trailer to detect nearby people, trigger alerts or imaging, and improve rear gate access safety.

An intermediary controller automates vehicle data collection and updates across network end points, cutting downtime, access risk, and management cost.

A normally open SmartFuse closes only after smartphone-based driver verification, blocking unauthorized vehicle starts and theft attempts.

Non-visual motion sensing verifies approaching users by gait, reducing key and biometric exposure while enabling secure vehicle access.

Millimeter-wave radar captures fingerprint and gesture signatures through the car surface to replace lost or stolen keys with secure biometric access.

Serrated nut and sleeve contact locks battery clamp preload under vibration, preventing loosening, noise, deformation, and battery drop.

A wedge lock and spring-loaded slide simplify steering assist packaging while resisting torque and ingress or egress loads.

Function-specific authority data and expiry settings let an NFC card key limit door, trunk, or engine access if the card is lost or stolen.

Local risk scoring maps attacked vehicle components and their dependencies to trigger faster, targeted incident response without remote delay.

A waveguide-based door interface projects gesture cues on transparent surfaces while sensing actions for intuitive, secure, contactless operation.

Electronic key identification triggers stored user settings for seats, mirrors, and climate, reducing manual startup steps and improving safety.

Automated action plans and continuity control keep vehicle data collection and updates running without direct access, reducing downtime and risk.

A controller interprets automation descriptions into endpoint commands, enabling vehicle data collection and responses without direct access or risky OTA updates.

A remote unlock command shifts the door to standby, then proximity and facial recognition trigger hands-free entry while reducing theft risk.

A low-power smart sound sensor enables local voice command recognition for parked vehicle remote functions without heavy ECU or cloud processing.

A pivot shaft and transmission mechanism let the steering wheel rim stow away, freeing driver space while preserving precise steering position.

RFID and photoelectric door actuation pairs with kneeling suspension to ease cargo loading and reduce manual effort.

When a fob is left inside a locked vehicle, selective LF/RF deactivation helps prevent theft and battery drain while preserving essential access.

Authorized device location triggers vehicle handle deployment before pickup, reducing door-opening delay while preserving aerodynamic efficiency.

Low-power sound sensing gates ECU activation and maps voice events to key-fob codes for reliable parked-vehicle remote functions.

Threshold-based sensing stops authentication after failed user detection, cutting vehicle smart entry power use without losing convenience.

A secondary clutch-based unlock path transfers external handle or remote power to unlatch a vehicle door when the main keyless entry power fails.

When vehicle battery voltage drops, contactless charging powers stored-energy unlatching so the door can still open without heavy emergency mechanics.

UWB modules on separate vehicle closures estimate door opening angle from time-of-flight ranging, avoiding multiple dedicated sensors.

External vibration sensing detects cutting or removal attempts on catalytic converters and triggers alarms or wireless alerts before theft succeeds.

When registered biometrics become unusable, the vehicle disables biometric login after successful fallback authentication from a mobile device.
