Anti-Theft Devices TRIZ Cases

Detects vehicle angle changes during unauthorized jacking to protect tires and catalytic converters while limiting false alarms.

Interlocked cover, bottom plate, and service cover locks enforce a specific battery pack disassembly sequence to block unauthorized maintenance.

By blocking window opening and closing after a lock command in parked or stopped states, this case prevents vehicle in-lock without extra sensors.

Embedded steering wheel sensors detect erratic heart rhythms and trigger safe vehicle slowdown when driver health or emotional distress is detected.

Motion and tilt sensing trigger brake lock, siren, and alerts to deter trailer theft beyond passive locks and tracking.

Fluid pressure checks replace slope-sensitive level sensing to enable safer remote work machine starts with less idling, delay, and stress.

Per-key driving force limits let shared-vehicle users keep suitable pedal response while still receiving abnormality alerts when limitation control is off.

Progressive floor elevation and raised seating add underfloor stowage, improve visibility, and upgrade bus safety without fleet replacement.

Controller logic disables unnecessary fingerprint detection after other authentication or at higher vehicle speed to suppress radio noise.

An elastic decorative vehicle element doubles as the lock actuator, shielding the internal sensor from weather and false readings.

A threaded sleeve and locking bolt mechanically stop force-free steering shaft rotation in parked steer-by-wire systems.

Periodic UWB channel remeasurement detects cabin obstructions and switches vehicle anchors to keep intrusion and child presence features active.

A stepped key lock collar balances friction along the steering shaft to prevent lock key breakage without impairing smooth steering.

Wireless channel reciprocity and RSSI feature correlation help verify nearby devices and block relay attacks in keyless vehicle entry.

Authorized users can adjust seats, mirrors, or climate settings by voice before entering, reducing awkward in-cabin setup.

A vehicle-mounted safe limits phone access, enables charging and essential communication, and blocks driving until the device is secured.

A mobile device stores and forwards vehicle key lock requests, blocking unauthorized digital key addition even when radio shielding delays contact.

A transport unit uses location-based requests, authentication, and selective coupling to move shared mobility devices indoors and outdoors.

A locking mechanism blocks unauthorized digital key storage and allows new key provisioning only after an authorized vehicle key unlocks it.

Combining body-shape sensing, obstacle distance detection, and smart key ID, this case suggests unparking when door-side entry is blocked.

Interior feature matching adds vehicle-geometry verification to face and liveliness checks, blocking spoofing by playback or 3D masks.

Out-of-band device identification adapts secure ranging to cut key FOB power use while maintaining reliable vehicle access.

A timed link between lock sensor touch and handle pull prevents missed unlatching when users open the vehicle door too quickly.

Temporary user setting changes are stored during device updates, then compared and merged after completion to avoid lost or inconsistent settings.

Mounting a fixed wireless communicator near the floor helps capture direct waves first, improving in-space position estimation when shielding degrades signals.

Continuous in-vehicle identity checks compare the current user with the authenticated driver and restrict enabled functions if a different person is detected.

Approach-region tracking and movement thresholds prevent unintended vehicle door unlocking and reduce battery drain.

A mobile interface streamlines IID recalibration, lockout reset, payment, and status handling without manual service-center calls.

Local event monitoring lets a parked vehicle detect theft risk, alert on exposed valuables, relocate itself, or call nearby vehicles to block theft.

State-based monitor lists adapt vehicle intrusion checks to driving conditions, improving abnormal data detection without excessive processing load.

Orientation-aware camera switching keeps a virtual rearview mirror aligned while expanding rear visibility and adding wireless safety functions.

When a charging worker unlocks the vehicle, an interior camera captures images for user monitoring to reduce anxiety about unauthorized actions.

A smartphone-authenticated unlock mode lets the access key transmit only after user verification, blocking relay attacks without extra key hardware.

Mobile, biometric, and geofenced authorization adds secure fuel account control with real-time transaction alerts and dispenser approval.

When central access control fails, a communication device directly triggers the window lifter to open a vehicle window for non-destructive entry.

Intermediate Bluetooth status signals keep vehicle digital key sessions alive during long-running remote functions and prevent timeout cancellation.

A lockable power compartment prevents cable removal during vehicle software updates, avoiding power loss and update abnormalities.

Proximity detection plus voice or gesture input unlocks a motor vehicle without active authentication, improving access speed and convenience.

Wireless ignition-circuit disconnection helps deter vehicle theft, avoid invasive installs, and scale secure control across fleets.

Balance weights let an asymmetric aluminum wheel cover suppress tire rotation vibration while preserving styling and anti-theft fastening.

Communication is cut between the in-cabin user terminal and vehicle during locking, preventing unauthorized engine start if the key is left inside.

Indoor weight sensors track passenger and item changes in valet mode to limit vehicle functions and alert against unauthorized access.

A locking anti-theft cover conceals roof rack fixing holes and screws, making crossbar removal much harder without adding bulky structure.

Revocation checks digital key use status, future need, and vehicle state to avoid disabling vehicle access during active or expected use.

Aligned inner and outer hook holes with an integrated lock mechanism immobilize ATV and pickup truck wheels and deter theft.

A slidable kingpin housing and actuator block unauthorized trailer coupling while allowing controlled unlocking for legitimate use.

Environmental imaging and map generation improve vehicle biometric unlocking by verifying identity with road context, habits, and access needs.

Occupant and seatbelt status trigger passive key searches when doors are removed, improving fob detection while reducing battery drain.

Ultrasound sent through the vehicle shell detects external hand gestures, replacing buttons or apps with faster, contactless vehicle control.
