Mechanical Machines/Dredgers TRIZ Cases

Real-time center-of-gravity and ballast sensing adjusts speed and turn radius to prevent lateral tipping in loader-equipped machines.

Controller logic separates excavation and alignment actuators, limiting approach speed so the work tool follows angled design surfaces accurately.

A fixed-position detection icon changes display mode with sensor results, helping operators spot people around work machines faster.

Independent front-wheel speed control uses vehicle speed and IMU yaw data to suppress traction loss in motor grader turns.

Design-data-based coordinate conversion keeps work and entry-prohibited areas fixed as the machine moves, improving boundary accuracy and safety.

Predictive swing control slows or stops an excavator upper body before the attachment reaches overhead wires during land leveling.

A backup limiting unit takes over when the first limiter fails, maintaining drive unit motion control and work machine safety.

A compact excavator cooling layout uses one fan and two airflow paths to cool refrigerant and hydraulic oil heat exchangers efficiently.

A single fan and split airflow paths cool both radiator and oil cooler in a compact electric excavator layout with limited space.

A fixed-position detection indicator changes color or form with detection results, reducing screen clutter in work machine monitoring.

External bearing plates move pivot bearing points out of the sheet metal box, cutting excavator stick fabrication cost, weight, and instability.

A telescopic stabilizer leg and foot adjust support span and ground contact to reduce swaying and improve wheeled vehicle stability on uneven terrain.

Sensor-based attitude monitoring warns operators and restricts excavator movement on slopes to prevent forward tipping.

Automatic threshold-based implement state changes reduce loading and hauling time in underground machines while cutting operator intervention.

Truck operation detection lets the excavator wait at the unloading position and discharge only when the vehicle stops at the loading point.

A winch and movable pulley attachment lets work machines build towing force gradually, reducing shock loads and damage when recovering stuck vehicles.

Turning angular velocity replaces vulnerable steering and articulation sensors to control differential lock and help motor graders recover rear wheel slippage.

Variable negative control adjusts hydraulic pump discharge to operator input, supplying needed oil while cutting unnecessary flow and energy use.

Cutoff strength is adjusted by approach velocity and collision time to prevent work area invasion without unnecessary excavator slowdown.

Sensor-based control sets target excavation depth from soil hardness, improving digging efficiency while preventing bucket sticking.

A curved hitch-pin path and non-uniform frame width let a compact loader keep vertical lift, wide tracks, and a small footprint.

Combining pressure, position, and machine parameters improves wheel loader payload and center-of-gravity accuracy as bucket fill shifts.

Oversized tracks on a sub-36-inch loader improve soft-ground load distribution while preserving maneuverability and a compact footprint.

An orientation detector triggers alarms during backward travel so shovel operators check the true rear direction and avoid movement-related accidents.

Dynamic negative control adjusts hydraulic pump flow to operator input, avoiding excess oil discharge while maintaining actuator response.

Distributed energy storage and slip ring power transfer balance loads across an electric excavator while cutting charging losses and thermal stress.

Variable magnification in a work machine bird's-eye view enlarges the turning-radius caution zone for clearer peripheral monitoring.

A dual relay power path cuts control-device power during remote standby, avoiding communication-related energy waste while enabling quick restart.

When swing inertia outlasts work equipment motion, the control retracts a low bucket and brakes swing to avoid loading-object interference.

A control device enables temporary power bursts and load prioritization so electric power machines can finish tasks without immediate recharging.

A BEIM-based control setup adapts machine modes, load monitoring, and interfaces for safer remote earthmoving outside the cabin.

An articulated axle layout and rotatable seat balance load stability with clear operator visibility on uneven construction terrain.

Independently actuated catch hooks with spring reset keep attachments secure during changes and reduce collision risk from lock movement.

A dual-mode hydraulic circuit reroutes supply and return flow so secondary actuators work efficiently without overheating or degrading primary function.

Automatic load detection blends track steering with blade tilt control to keep bulldozers on grade lines under heavy loads.

An annular liquid nitrogen insert shrinks an interference-fit centre pintle for faster removal with far less nitrogen and no lancing.

Controller-timed valve switching lowers pump pressure before actuator connection, reducing shock during accumulator-to-actuator transitions.

Autonomous underwater harvesting swarms collect polymetallic nodules with coordinated mapping and communication while minimizing seabed disturbance.

Automatic relief valve control depressurizes auxiliary hydraulic circuits during tool changes, reducing manual effort and preventing drift or damage.

Swarm-operated underwater drones collect polymetallic nodules through hubs and AI coordination to raise uptime while limiting seabed disturbance.

Feedback channels and shaped outlet geometry help a hydraulic switch start oscillation reliably, stay stable, and cut pressure loss.

A spring-loaded catch hook pivots independently of the lock to avoid attachment collisions and keep quick changes secure on construction machines.

Acceleration feedback corrects boom cylinder commands during rapid operation to suppress oil-column vibration and improve work quality.
