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.

A traction aid uses a central gear and pivoting brackets to adjust its geometry for secure mounting on various tire sizes.

An arcuately-shaped frame with radial clips secures a traction portion to a wheelchair wheel, enabling quick deployment on irregular terrain.

A resiliently deformable element connects the ring gear to the hub, enabling gradual torque transfer between the wheel rim and power-transmission components.

Elongated flexible elements stored within a tire rim structure deploy automatically via elastic return means to form a snow chain.

Passive camber mechanism engages small diameter tires during turns to increase traction without manual intervention.

Telescopic covers expand wheel bases to resolve tipping risks on soft terrain without increasing device complexity.

Spaced rigid members in the wheel rim allow mud passage to prevent deep tracks while maintaining traction.

Segmented tyre claws and a jacking head lift trapped wheels, avoiding the time lost mounting heavy anti-skid chains.

Coaxial auxiliary wheels provide traction on rough surfaces without increasing overall tire width.
