Belt Control Systems TRIZ Cases
- Seatbelt Tongue Angle Sensing for Improper Belt Position Detection
A Hall sensor tracks seatbelt fitting rotation to detect diagonal belt misuse and support adaptive occupant safety responses.
- Seat Belt Position Detection to Prevent False Buckling
Occupancy, buckle, and tag-based position sensing blocks machine startup when a seat belt is fastened incorrectly behind the user.
- Occupant Injury Risk Prediction Using Two-Stage Collision Modeling
Two linked learning models turn vehicle, scene, occupant, and restraint data into body-motion curves for more accurate collision severity assessment.
- Seat Belt Webbing With Invisible Pattern and Uniform Color
Two yarns with different invisible-light reflectance create a detectable seat belt pattern, while overdyeing keeps the webbing visually uniform.
- Autonomous Driving Handover Feedback with Fallback Driver Alerts
When a primary seat or belt feedback path fails, the vehicle switches to backup driver alerts to secure control handover.
- Seat Belt Webbing Pattern Detection for Correct Passenger Restraint
Infrared-reflective webbing patterns and vision sensing distinguish correct seat belt wear from fake fastening or abnormal use.
- Electromagnetic Buckle Lock Indication for Dark Ride Restraints
Magnetic rod detection and color display show buckle lock status in dark ride restraints without touch, reducing inspection contact and assembly complexity.
- Autonomous Driving Mode Switching with Driver Safety Checks
Pre-switch vehicle, environment, and driver checks gate autonomous mode changes and issue corrective tasks to keep transitions safe.
- Motorized Retractor Assembly for Child Seat Webbing Lock Control
A sensor-guided retractor unlocks webbing for child seat installation, then locks and retracts it to cinch slack after correct tethering.
- Seat Belt Webbing IR Marking for Anti-Spoof Position Detection
Laser-ablated infrared markings let optical systems verify true seat belt positioning while preserving webbing durability and hidden customization.
- Seat Belt Tongue Assembly With Pre-Fixed Electronics
Pre-fixing the carrier-mounted electronics to the seat belt tongue simplifies assembly, prevents dislodgment, and protects components during molding.
- Seat Sensor Recessed Mounting for Passenger Comfort
A recessed seat sensor mount in a board-like member hides the sensor under the cushion pad to improve comfort and maintain accurate occupancy detection.
- Safety Belt Retractor RFID Tag Placement Outside Body Pillar
Mounting the RFID transponder on seat belt webbing outside the body pillar enables reliable belt retractor tracking during vehicle assembly.
- Vision-Based Seat Belt Detection for Proper Wear Verification
Image-based cabin analysis verifies proper seat belt routing, avoids buckle false positives, and removes wiring complexity in adjustable seats.
