Suspensions TRIZ Cases
- Air Spring Abnormality Detection via State Estimation Model
An extended Kalman filter estimates virtual gains to identify faulty air springs, enabling rapid vehicle body leveling and simplified repairs.
- Vehicle Seat Suspension Using Common Hydraulic Actuator
Integrating damping and height adjustment into one hydraulic actuator reduces device complexity while maintaining vibration isolation for utility vehicles.
- Steering Knuckle Enlarged Wall Portion Weight Reduction
An enlarged peripheral wall portion expands the hollow volume of a vehicle steering knuckle, resolving weight reduction conflicts with rigidity requirements.
- Trailer Braking ECU Remote Pairing via Communication Bus
Electronic braking system automates trailer identification using MAC addresses and secure codes to eliminate manual verification errors in large depots.
- One-Piece Cast Iron Rear Axle Subframe Design
A one-piece cast iron subframe integrates bearing mounts and connection arms to eliminate welding operations.
- Fabricated Axle Removable King Pin Weight Reduction
Segmented high-strength steel components replace monolithic forged axles, resolving the strength versus weight trade-off for heavy-duty payloads.
- Socket Assembly Deformable Wall Preload Reduces Internal Clearances
Deformable housing wall preloads spring against backing bearing to minimize internal clearances, extending operating life without adding collapsible components.
- Steering Sensor Pin Assembly With Flat Face And Axle Slot
A steering sensor pin assembly uses a flat face to couple with an axle beam slot, eliminating threaded holes and locking nuts.
