Tyre Parts TRIZ Cases
- Tire Retreadability Screening Using Chemical and Physical Degradation
A two-stage tire assessment combines chemical aging and physical damage checks to improve retreadability decisions without unnecessary inspection steps.
- Tire Heating Control Using Excess Power to Cut Rolling Resistance
Excess generated power is redirected to tire heating when battery absorption is limited, cutting rolling resistance and extending EV range.
- Self-Sealing Tire Structure for Low Off-Gassing Vulcanization
A stiff encapsulating layer breaks down during vulcanization to form sealant, cutting off-gassing and preserving tire uniformity and balance.
- Steering Feedback Torque Using Wheel and Roadway Sensor Prediction
Wheel and roadway sensors predict high-frequency wheel-road interactions to deliver faster, more accurate steering torque feedback.
- Electric Drivetrain Inverter Diagnosis via Current Spectrum Analysis
Current Fourier analysis reveals inverter anomalies and optimal switching frequency in electric drivetrains, reducing noise and energy loss.
- Tire Balancing Bead Mix for Moisture Control and Flow Stability
A mixed bead fill uses super absorbent beads to remove tire cavity moisture, preventing clumping, valve clogging, corrosion, and pressure swings.
- Tyre Force Sensor Layers Using Triboelectric Self-Powering
Different intermediate layers in a tyre sensor generate triboelectric voltage from friction, enabling force measurement without external power.
- Self-Sealing Tire Cavity Foam Layout to Prevent Sealant Sticking
A silicone foam layer and intermediary adhesive reduce tire cavity resonance noise without blocking sealant flow or puncture sealing.
- Inflatable Wheel Partition Assembly for Tire Cavity Resonance
Inflatable baffles segment the tire cavity to raise resonant frequencies and reduce cabin noise from tire vibrations in EVs and hybrids.
- Pneumatic Tire Helmholtz Absorber Layout for Cavity Noise Reduction
A tuned Helmholtz absorber frequency spread cuts tire cavity resonance across running speeds while reducing absorber count, weight, and complexity.
- Wheel Hub Test Bed Using Virtual Wheel Dynamics
Virtual wheel dynamics and hub loading make road interaction more realistic on a test bed, enabling vehicle tuning without a physical prototype.
- RFID Tag Coil Transformer Layout for Durable Rubber Tracking
A coil-based coupling transformer and PCB-in-gap layout help rubber RFID tags resist deformation and carbon black impedance shifts.
