Pneumatic Tyre Reinforcements TRIZ Cases
- Run-Flat Tire Crown Corrugation for Comfort and Low Rolling Resistance
A corrugated crown layer placed close to the sidewall insert improves run-flat support while preserving comfort, handling, and low rolling resistance.
- Tire Belt Structure Balancing Rolling Resistance and Durability
A three-layer belt layout with tuned cord angles and widths cuts rolling resistance while preserving heavy-duty tire durability.
- Elastomer Reinforcement Cord Filling for Rust Resistance and Adhesion
Controlled resin filling between metallic filaments blocks water paths while preserving rubber adhesion and corrosion fatigue resistance.
- Dual-Layer Wire Assembly Reconfiguration for Tire Reinforcement
Separating and reassembling a temporary core-based wire assembly preserves linear mass, uniform wire geometry, and endurance in tire reinforcement.
- Pneumatic Tire Belt Structure Balancing Durability and Weight
A steel-and-organic cord belt structure cuts tire weight and bending rigidity while preserving high-speed durability and driving stability.
- Passenger Radial Tire Noise Reducer Layout for Heat and Durability
Segmented inner tire noise reducers with thicker shoulder regions cut cavity noise while limiting heat retention and adhesion failure.
- Hybrid Band-Layer Tire Structure for High-Speed Steering Stability
Hybrid band cords and tightly controlled groove-side rubber thickness improve high-speed steering stability without sacrificing ride comfort.
- Steel Cord Twist Pitch for Straightness Without Filament Fracture
Controlled twist pitch keeps steel cord tip rise below 5 mm, improving splicing straightness while lowering filament fracture risk.
- Rolled Steel Cord Structure for Low-Resistance Tire Belt Reinforcement
Periodic rolling creates mixed circular and non-circular wire sections that cut tire rolling resistance while improving rubber adhesion and fatigue life.
- Recycled PET Tire Cord Composition for Heat-Resistant Tires
By controlling intrinsic viscosity and isophthalic acid, recycled PET tire cord keeps heat resistance and strength comparable to virgin PET.
- Tire Tread Groove Layer Layout for Wet Grip and Separation Resistance
A stress relaxation layer extends from the groove bottom onto land edges to resist separation while preserving exposed tread area for wet performance.
- Pneumatic Tire Bead Reinforcement Layout for Heavy-Load Durability
A layered bead reinforcement layout improves heavy-load tire durability by increasing rigidity, lateral support, and strain control.
- Tire Bead and Sidewall Structure for Stiffness Transition Control
A segmented apex and ply turnup layout stiffens the bead-sidewall transition, improving force direction and tire durability.
- Tire Bead Conductive Path for Low Rolling Resistance
An embedded conductive rubber path in the bead and carcass releases static electricity without raising carcass carbon content or rolling resistance.
- Low Turned-Up Tire Carcass for Bead Durability at Lower Mass
A low turned-up single carcass ply with tuned sidewall thickness improves bead durability while keeping mass low in high-load tires.
- Steel Cord Structure With Stronger Core Filaments for Low-Fracture Twisting
A stronger-core, weaker-sheath steel cord cuts filament fracture during twisting while maintaining high breaking load and production efficiency.
- Twisted Metallic Tire Cord for Part-Load Elongation and Adhesion
A helical metallic tire cord uses controlled twist pitch to raise part-load elongation while improving elastomer penetration, adhesion, and corrosion resistance.
- Heavy-Duty Tire Buffer Layer Structure for Stable Ground Contact
Thicker hump portions in a crosslinked rubber buffer layer suppress belt-end lifting, stabilizing ground contact while reducing tread load and tire mass.
