Tyres TRIZ Cases

Dual auxiliary drums synchronize carcass building with tread band assembly, resolving productivity mismatch between stations.

A distal air deflector accelerates heated air through an elongated chamber, eliminating recirculation zones that cause uneven tire curing.

A pneumatic tire reinforcing belt uses parallel and spiral winding treatments to distribute overlapping irregularities evenly in the circumferential direction.

Independent rotation of the mold cap and outer ring opens the pouring slot during filling, reducing downtime in automated production.

Buffer devices decouple mixing and shaping to resolve contradictions between production speed and longitudinal uniformity in self-sealing tyres.

A pneumatic tire deploys retractable studs to increase friction on ice while keeping them retracted on dry pavement.

A tire curing mold uses larger vent holes in recess portions to promote rubber flow and air dispersion.

Thermoplastic elastomer sockets seal sealant bottles without O-rings, reducing device complexity.

A mold blade shapes the cover layer during vulcanization, reducing shear-induced cracking and thickness variations in the tread.

Radial undulations in a tire sipe reduce rolling resistance by 3% while increasing wear life by 7% through dynamic stiffness changes.

Instant vaporization of a cleaning solution on heated workpieces generates micro-explosions that remove micron-scale dirt without surface corrosion.

Hydrocarbon polymer modifiers in isobutylene-based elastomers reduce butyl rubber reliance while extending pull point and improving heat transport efficiency.

Adding specific inorganic fillers to the polymer matrix achieves isotropic thermal expansion without complex biaxial stretching equipment.

Merging four pull rods into one assembly reduces occupied space while maintaining mold clamping precision.

Servo motors replace pneumatic cylinders to eliminate mechanical stops, ensuring accurate positioning and reduced cycle times.

Variable thickness profile on tyre tubular structures prevents tearing and micropunctures during toroidal shaping.

A locking element secures a removable insert in a tyre mould sidewall plate seat using resilient snap-action.

Embedding electronic structures within the tire base material prevents sensor detachment during rotation while maintaining reliable data collection.

Segmented pallet design employs a flexible non-stick support element to reduce adhesion and weight for easier tire handling.

A pneumatic tire inner surface recessed region anchors mechanical fasteners to prevent attached objects from rotating during rolling.

Opposite-threaded bolts and springs move drum parts symmetrically, eliminating bending loads from non-coaxial torque transmission.

Segmented rolling with a narrow roller reduces tread elongation while ensuring reliable adhesion across different casing types.

A tire vulcanization mold uses segmented side pieces to form vent gaps and separate replacement pieces for information display.

Deflection roller stabilizes cord band against lateral oscillation and crushing during slitting.

Curved mold parting lines limit sector misalignment in tire vulcanization molds, reducing rubber squeeze-out at sidewalls.

A joining device positions a second strip leading end closer to a support plane using a deflection member for precise placement.

Segmented presser elements ensure uniform adhesion across strip-like elements, preventing unevenness at ends on high-camber outlines.

Segmented driving pins automatically lock into rim recesses, preventing slippage and damage during tire service operations.

Placing the optoelectronic relief on the tread instead of the sidewall preserves structural integrity while maintaining robust readability.

A tire post-inflation apparatus uses staggered vertical station mechanisms with cross beams and swing arms to reduce overall height.

A movable linkage assembly transitions between retracted and extended positions to spread a tire envelope.

Multiple strip circuits and carcass inflation prevent buckling and ensure uniform pressure for reliable adhesion.

A tiltable curing press cover uses a slidably guided axle to pivot and slide, increasing free height for tire loading.

Slidable tie rods allow segments to retract and swing, reducing mold removal forces for complex tread patterns.

Knurled grooves on the bead ring create specific gaps that reduce rubber residue entry, ensuring efficient gas discharge.
