Wheels TRIZ Cases

A shared roller bracket and limited second shaft reduce roller gap, shake, noise, and vibration for more stable omni wheel running.

By reading magnet drive output during wheel rotation, the robot confirms surface adhesion without visual checks or prior surface data.

Raised traction elements on independently rotating wheel rollers improve grip and odometry on soft surfaces without adding high stress or power demand.

A locked second shaft and dual-roller bracket reduce roller shake, noise, and vibration while improving omni wheel running stability.

Sliding magnets and a clutch vary magnetic flux so wheels hold ferromagnetic surfaces securely yet disengage with lower effort.

Helical fins and a forward mass bias help this granular mobility case climb slopes with better traction while enabling subsurface sensing.

A multiaxial wheel shifts between free omnidirectional rolling and surface-engaged control to balance maneuverability with stability.

Rotating discs and a serpentine isolator ring switch magnetic flux paths, giving ferromagnetic wheels strong grip and easier disengagement.

Alternating axial roller placement overlaps gaps in an omnidirectional wheel, reducing impact and noise while improving ride quality.

A star-spoke unitary frame spreads roller loads to keep omniwheels strong yet light, while reducing fasteners, material use, and assembly complexity.

Complementary members fill recessed gaps between adjacent rollers in a mecanum wheel to reduce impact, noise, and ride-quality loss.

Automatic magnet orientation control lets a wheeled moving device transition from floor to wall with less sticking, delay, and operator effort.

Controllable magnetic coupling replaces external supports in spherical wheels, reducing slip, debris jamming, and maintenance.

Elastic spoke plates and a rotating collar let a robot wheel change diameter for better obstacle crossing and terrain adaptability.

A gear-driven three-link wheel mechanism retracts an auxiliary wheel in less space, cutting component count, weight, and failure risk.

Larger wheel diameters and differential motor control cut axial friction and improve electric car range and traction stability.

Segmented bearing seating and adhesion grooves stabilize a hubless wheel bearing to simplify assembly, cut weight, and reduce noise.

A rotatable support unit longer than the wheel radius helps driving robots lift onto step tops and cross stairs without bulky mechanisms.

Larger rear wheels and motor torque control cut axial friction losses, helping electric passenger cars travel farther per charge.

A polygonal three-leg handle support resists rotation, improving steering accuracy and comfort for carts and other moving bodies.

Elastic connective elements built into an omni-directional wheel absorb rough-terrain impacts, cutting vibration and suspension weight.

A cable-actuated tensegrity wheel expands for soft-terrain traction and obstacle climbing, then collapses to cut robot weight and cost.

A rebounding retaining structure and locking recess let worn mecanum wheel rollers be replaced quickly without sacrificing radial and axial retention.

Repeated motor-rotation and yaw measurements generate correction coefficients that improve directional accuracy in omnidirectional moving bodies.

A central gear passively deploys pivoting legs to switch between rolling and legged motion, improving obstacle crossing with less control complexity.

A mixed drive-wheel and omnidirectional-wheel layout stabilizes six-leg cargo movement on flat ground and stairs while reducing fall risk.

Larger EV wheels paired with motor control and steering reduce axial friction, extending driving range per battery charge.

A movable rim disc and aero ring vary wheel airflow between open and closed states to improve brake cooling while preserving aerodynamic efficiency.

Alternating large and small rollers with dual-arm supports improve load distribution, cutting wheel weight without sacrificing durability.

A central ring with bearings lets the rim and tyre rotate without spokes, creating a simpler hubless bicycle wheel with safer, robust support.

Hot forging below the abnormal grain growth range and with hotter tools prevents surface cracks, cuts excess weight, and preserves properties.

Tilting a ring or disc blank during machining prevents chip and coolant buildup, improving cooling, visibility, and material use.

Flat radial portions wider than lathe feed preserve wheel styling while creating a stable reference plane for accurate dimension measurement.

Tilting a disc or annular blank during machining prevents chip and coolant buildup, improving cooling and process visibility.

A circumferential undercut lets anti-skid chain hooks move on a rim adapter, easing attachment to curved vehicle rim cups and preventing damage.

Offset spherical rollers in this omniwheel assembly overcome obstacle traversal limits while maintaining smooth all-directional motion.
