Off-Road Vehicles TRIZ Cases

A symmetric HMI simplifies control of wheeled-walking hybrid vehicles by adapting modes, switching operators, and supporting multi-vehicle operation.

A shared intake box and shield wall protect engine and CVT inlets from water and dust in off-road vehicle front intake routing.

A two-stage muffler layout under the cargo bed cuts exhaust noise while preserving packaging space and reducing thermal impact on nearby parts.

A coupling and adjustment assembly lets the steering wheel swing clear for entry, then return to a selected driving position without re-adjustment.

Driven wheels are matched to winch-induced vehicle speed to cut winch power draw and reduce electrical stress on the low-voltage system.

An electronic controller estimates torque assist before a shift to synchronize rotating elements and avoid clutch slip, heat, and wear.

Pre-adjusting suspension damping and vehicle height before launch control helps small vehicles start quickly without upsetting vehicle attitude.

Compact rear turbo placement boosts utility vehicle power while staged oil reservoirs and intake cooling manage heat and oil flow on steep terrain.

A removable control unit lets operators run a utility vehicle from outside and switch to sensor-based target following to cut reentry delays.

Active suspension shifts wheel normal force toward higher-grip wheels to improve traction and stability on uneven surfaces.

Distinct buzzer timing patterns let drivers identify work vehicle abnormalities by type and urgency, even during high-speed travel.

Sequential wheel steering, suspension weight shift, and torque create serpentine motion to free stuck vehicles on uneven terrain.

During overrun at low speed, torque is shifted between axles to limit wheel slip and material wedge build-up while keeping deceleration stable.

Real-time terrain classification and target slip estimation help maintain maximum traction on snowy, sandy, muddy, icy, and gravel roads.

A lockable split rear axle lets OHV wheels run together off-road or independently on pavement to cut tire wear and improve turning control.

A switchable speed-hold mode automatically adjusts driving force to keep utility vehicles stable on uneven off-road terrain.

A close-coupled turbo, staged oil reservoirs, and water cooling improve utility vehicle power delivery under heat and high-angle terrain.

Real-time stuck probability adjusts torque and braking slope to keep off-road vehicles moving without worsening instability or bogging down.

Separate intake conduits and dual fuel injection cool supercharged intake air, prevent knocking, and avoid airflow interference at the valves.

Geofencing automatically switches vehicles into low-speed and low-SPL modes in regulated areas to meet road and noise limits.

Location-based control switches an off-road vehicle into low-speed and low-SPL modes inside geofences to meet road and noise rules.

Past location-linked speed, acceleration, and sprung-weight data estimate road unevenness so rough-terrain controls can cut vibration and wheel slip.

A front coupling break point limits excessive torque, while a cantilevered pivotal seat adds under-seat storage in a side-by-side ATV.

A detachable fuel tank, regulator, and outlet module simplifies gas-fuel vehicle maintenance by enabling single-unit removal and service.

Route and map data let the suspension switch settings before new road sections, reducing response delay, discomfort, and unnecessary energy use.

Sensor-based tractive feedback adjusts propulsive and braking torque on changing off-road surfaces to prevent wheel spin and stalling.

Separate wheel-end motors remove long shafts and axles, cutting vehicle size, power loss, and lubrication needs in narrow off-highway sites.

Passive RFID helmet detection lets the vehicle limit speed or power when no helmet is present, improving rider safety at low cost.

A suspension member placed between the trailing arm surfaces limits rear wheel toe change at full compression, improving stability and directional control.

Independent coaxial wheel-end motors replace the axle and drive shaft, improving off-highway maneuverability while reducing power loss and oil use.

Using route and road-type data, the suspension switches ahead of upcoming sections to cut response delay, unnecessary adjustments, and energy waste.

A modular frame keeps wheelbase and cargo pivot geometry consistent across utility vehicle variants, simplifying assembly and adding protected storage.

At low speeds on loose surfaces, shifting overrun torque between axles limits wheel slip and material wedge buildup while preserving deceleration.

By placing the stabilizer bar ahead of the radiator, this ATV layout improves front-end stability and simplifies mounting in limited space.

A detachable seat back and lock lever create clear rear access to the electric component box while keeping the seat stable and protected from dust and water.

A laterally placed transmission and horizontal cylinder axis cut engine height, avoid interference, and preserve off-road ground clearance.

Macro-capacitive sensors track seated, leaning, or standing driver positions and adjust throttle and braking to prevent unintended vehicle response.

By nesting the motor within the drive wheel periphery, this tracked vehicle frees space for suspension while keeping drive, brake, and transmission compact.

A spring-biased solenoid and grooved cam lock the shift lever in park, then retract under brake, ignition, and idle-speed conditions.

A control-arm suspension keeps six-wheel robot chassis wheels in ground contact, improving obstacle crossing, stability, and damping on uneven terrain.

A four-isolator utility vehicle powertrain mount separates engine and transmission support to improve transmission service access and engine stability.

A defined drivetrain break point limits torque damage, while a pivoting seat bottom adds storage and improves access to electrical connections.

Vehicle and weather data are combined to assess off-road surface traction, slope, and material so drivers can avoid routes likely to cause vehicles to get stuck.

Centered longitudinal arrangement of engine, integrated fuel tank, and rear gear unit reduces vehicle body width while accommodating electric accessories.

A rearward radiator uses a rotating fan to draw outside air inwardly, maintaining cooling efficiency without protective covers.
