Tyre Tread Bands/Patterns TRIZ Cases

Alternating oblique segments in zigzag middle main grooves improve wet drainage while maintaining tread rigidity for steering stability.

Groove bottom and wall protrusions disrupt air column resonance in longitudinal grooves, reducing noise while maintaining drainage.

Angled transverse groove sections balance snow retention and drainage by assigning distinct orientations to separate tread zones.

A foot-operated tensioning member replaces high hand force requirements by actuating a spring-loaded retraction system to secure the anti-slip device.

Disconnected zigzag grooves prevent air resonance noise transmission while maintaining drainage efficiency.

Asymmetric tread groove layout increases outer side rigidity to improve dry traction while inner channels enhance wet water drainage.

Asymmetric lateral groove arrangement reduces tire noise while maintaining mud performance through local quality variation.

Variable groove depth zones balance low noise in the center with wear resistance at the shoulders.

Asymmetric chamfered sipe edges direct water flow to improve wet traction while preserving rib rigidity for dry steering stability.

Segmenting shoulder grooves prevents air flow separation to lower aerodynamic drag while maintaining low rolling resistance.

Reducing adjacent profile rib height decreases load on the groove base.

Cut-out portions expose zig-zag sipe patterns on tread block interior walls, creating pockets to trap snow and improve traction.

Segmented stud pin geometry with asymmetric angles discharges small ice from recessed areas, preventing accumulation that reduces braking grip on icy roads.

Notched flexible blades detach during tread wear to maintain water flow and shift resonant frequencies away from human-sensitive ranges.

A stud pin upper flange features a recessed surface to collect ice powder and maintain traction on icy roads.

Alternating inclined portions within main grooves engage to maintain tread block stiffness while lateral channels discharge water efficiently.

A pneumatic tire uses differentiated groove depths in shoulder blocks to enhance tread rigidity and water drainage.

Varying sipe depths minimize molding interference with insert geometry while ensuring uniform wear transition as the tread wears.

Segmented recessed regions with varying heights create a stepped structure that concentrates contact patch pressure at inclined edges to enhance snow traction.

L-shaped sipes with lateral three-dimensional portions increase edge components in tire blocks, balancing rigidity to suppress uneven wear.

Angled raised edges on tread blocks boost edge pressure while micro-incisions drain water films to improve icy grip.

Segmented zigzag grooves with variable widths and local intersection angles resolve stone retention trade-offs while maintaining tread structural integrity.

Inclined ribs on tire groove walls use elastic restoring force to push trapped stones outward for easy removal.

Continuous central thin ribs with circumferential sipes reduce rigidity differences in tread blocks, minimizing rolling resistance and irregular wear.

Interlocking sipe protrusions and recesses reinforce tire tread block edges, suppressing collapsing during ice braking to maintain contact area.

Zigzag center groove and bent lug grooves improve wet steering stability without reducing dry road rigidity, preventing uneven wear.

A pneumatic tyre tread pattern uses localized transverse groove widths to balance structural integrity and water drainage.

Gradient incision deflection limits block tilting to resolve uneven wear and improve icy road traction.

Alternating rubber blocks in circumferential grooves protect against stone ingress while maintaining wet grip properties through wavy groove shapes.

Segmented shoulder composite grooves reduce tread strain under contact pressure while maintaining wet drainage performance.

Thin grooves with varying depth ridges in the tread block suppress vibration sounds and heel-and-toe wear while maintaining structural rigidity.
