Castors TRIZ Cases

A bar-shaped pin and biasing member simplify caster locking in tight space while improving groove engagement and dual-axis braking.

Angled dual wheels on a rotatable strut improve luggage tracking and quietness while avoiding heavy bearings and debris buildup.

Independent spring-biased caster guards retract on contact with fixed obstacles, preventing binding, tip risk, and cable or hose damage.

A base contact portion cushions step impacts so a caster support bends elastically, reducing wheel damage without using a stronger tool.

Biasing members under the swivel brake plate absorb misaligned braking loads, preventing plate deformation and improving caster durability.

Adjustable front wheel placement aligns with deck suction zones to reduce grass compression and improve cut height uniformity on zero-turn mowers.

A gravity-aligned truckle support lets cabinets sit directly on the ground, improving rigidity, transport stability, and cable routing.

A deformable wheel cover encapsulates castors to block dirt and microbes while preserving furniture mobility and easy cleaning in hygiene-controlled spaces.

A single actuation link locks a caster against rolling and swiveling, improving cart stability on inclines and during unintended movement.

A pivoting cammed brake shoe deepens wheel engagement during rotation, cutting foot-pedal force while maintaining reliable caster braking.

An internal drum-and-band brake lets hospital casters lock in both directions while keeping patient support beds low and easy to move.

Independently movable retractable wheels raise a heavy gaming cabinet for transport, then retract for stable contact on carpet or tile.

A spring, follower, and swashshaft keep lifted caster wheels near centerline to avoid blocking short-range sensors on delivery vehicles.

A contactless axial lip, bypass section, and collection chamber divert water and dirt outward while reducing wheel bearing seal friction.

A cover pushes the hub bearing against a knuckle stopper to stiffen an off-road axle assembly, reduce rattling, and limit corrosion risk.

Opposed pivoting locking elements and a spring-assisted actuator hold a heavy mobile stand securely while keeping movement easy on uneven surfaces.

A slim flinger-and-sealing-body layout improves bearing sealing in contaminated environments while preserving standard boundary dimensions.

Carbon black in vehicle lubricant dissipates static charge at sliding parts, improving steering response and control stability.

Carbon black in vehicle lubricant helps neutralize driving-induced positive charge, improving steering stability without harsher damping or tread changes.

Non-uniform fastening angles improve load transfer in a wheel bearing outer ring while cutting mass and preserving stiffness and service life.

A self-centering puller applies even compression to remove and reinstall truck wheel bearing races without hammer damage across Class 1-8 hubs.

This caster uses guided slide-roller motion to reduce torsion and convert wheel contact into upward force for smooth stage climbing.

Independent wheel and arm springs absorb shocks and prevent misalignment, protecting cargo from damage on rough terrain.

Sensor-guided vertical adjustment of the crane drive wheel resolves traction loss on irregular terrain by dynamically maintaining optimal contact force.
