Auxillary Traction Increasing Equipment TRIZ Cases

A crown-shoulder seal lets pressurized spiked wheels stay airtight under dirt and load while improving traction, smooth running, and ground pressure.

A bead lock retention ring secures snow chains on large tires while preserving wheel rim access, easier handling, and a cleaner look.

Movable tread segments and heat-conducting elements help a rim-clamped emergency wheel attachment maintain traction and reduce wear on flat, icy, or snowy roads.

A lug-mounted traction bar restores grip on mud, sand, or ice while avoiding the heavy, slow installation of tire chains.

A segmented wheel attachment clamps behind the rim flange, enabling secure flat-tire assembly without a car jack and limiting wheel movement.

Adjustable rim fasteners and elastic contact surfaces keep a wheel attachment secure on flat tires and slippery roads while absorbing shock.

Independent positioning and rim clamping secure run-flat support elements that press tire sidewalls outward for stable emergency driving.

Two segmented wheel attachments use positioning, locking, and expandable grips to secure a flat tire quickly without complex tools.

A movable tread, damping system, and heat-conducting elements help a clamped wheel attachment restore mobility with less wear and better comfort.

A pivotable hook and contact surface clamp behind the rim flange to secure run-flat wheel attachments across varying tire and rim geometries.

A compact rim-mounted attachment uses spring-loaded fastening and a tread body to restore traction for flat tires, snow, or ice.

A segmented foldable wheel attachment mounts without removing the wheel or using a jack, enabling emergency driving after a flat tire.

A segmented hub-mounted wheel attachment enables secure installation on a flat or icy tire without wheel removal or vehicle lifting.

A vehicle wheel uses resiliently deflectable arms to engage surface irregularities and absorb shock.

A self-bracing wheel attachment uses a contact portion to actuate bracing means that engage the rim flange for secure mounting.

A portable escape device uses a spring-loaded jacking mechanism to lift trapped auto tyres from pits for rapid self-rescue.

A nested spare tire mounts inside the main wheel rim to support vehicle weight when the primary tire deflates.
