Cycles TRIZ Cases

A control module uses seat belt state and vehicle speed to limit engine rpm only above a threshold, reducing hazards without abrupt response changes.

A movable battery assembly within the snowmobile tunnel balances structural rigidity with center-of-mass adjustment for better stability.

Pressure-sensed bumper compression cuts motor power and applies braking so mobility scooters stop before causing further pedestrian injury or damage.

By placing axle bearing units below the pivot, this layout shrinks the front cover, preserves handlebar clearance, and allows greater tilt.

A front-wheel drive train and lever-engaged rear caster wheels let a kart induce and control drift during turns without a differential.

Swivel caster rear wheels and battery-powered front-wheel drive expand tricycle turning range while reducing pedaling effort and discomfort.

An AMT-driven single rear wheel improves power distribution in a three-wheeled vehicle while adapting gear ratio to speed, engine load, and throttle.

T-slot extrusions create a modular EV chassis that simplifies mounting, supports length changes, and seals battery and electronics from water and dust.

A freewheel hub layout couples brake shoe and anchor across the drive member to enable reverse drive without extra chains or a second axle.

Active lean motors rotate a chassis control shaft so a three-wheel vehicle can lean into turns, improving stability and reducing flip risk.

Electronic steering input, lean actuation, and added centripetal torque improve turning stability in a leaning front-wheel vehicle.

Independent left and right drive wheel control cuts turning radius while maintaining stability in tight personal mobility turns.

Track-facing radiator fins expose the inverter through the frame opening to dissipate heat while keeping the control unit sealed from snow and moisture.

A pivoted two-panel air brake shifts from a low-drag closed state to an acute-angle open state for stronger braking on wheeled vehicles.

Independent oscillating arms and a linear shock absorber decouple wheel motion and steering to improve tilting vehicle stability on uneven roads.

A single lean actuator adjusts vehicle body angle during riding and rider boarding, reducing actuator count while preserving stability.

Rearward IMU placement enables accurate lean angle control in a leaning vehicle while avoiding a larger, more complex front link area.

A separate frame supports the slanted footrest center, enabling resin footrests, higher stiffness, and easier engine servicing.

External-power battery heating keeps an electric snowmobile battery warm during charging, improving cold-weather efficiency and startup comfort.

A rotating seat steers all four wheels through linkages, removing axles and steering columns to cut weight and improve accessibility.

A bridge-and-upright front suspension lets a multi-wheel vehicle tilt deeply while isolating steering from suspension travel to avoid bump steer.

A split engine-motor drivetrain lets an ATV use electric low-speed torque and delayed engine start to improve 4WD efficiency and cut fuel use.

A rearward CVT linked by a belt keeps ATV power transmission while cutting drive package width and allowing closer foot-wells.

A mechanical elastic roller constrains the front tilt bar to keep low-speed tilting vehicles stable without electronic gyros or manual tilt locks.
