Mechanical Machines/Dredgers TRIZ Cases

A lateral display layout on the operation box keeps the screen visible by placing it outside the swing areas of the control levers.

Sidewall inlet apertures and guided airflow cool enclosed electrical prime mover components while limiting precipitation ingress.

Magnetic fluid held in a tubular holder carries heat from the motor and sun gear, preventing overheating and lubrication failure.

Visual cues on a dredge arm use light and predator silhouettes to move sea turtles away while maintaining dredging productivity.

A segmented bar display shows shovel load ratio by range, helping operators track truck loading progress faster than numeric-only screens.

Individual valve opening control adjusts boom float to match scraping, breaking, and excavation modes without added hydraulic hardware.

Current-matched control keeps paired electric actuators force-balanced on a shared load, reducing wear, maintenance, and downtime.

Travel restraint is applied only in directions toward a detected object, using revolving angle data to reduce unnecessary stops and avoid collisions.

Camera overlays show implement offset and inclination in real time, helping operators align loader couplings despite boom-obstructed views.

Controller-based load correction adjusts actuator commands by posture, distance, and sensed load to keep excavation accurate near target surfaces.

A single differential with opposed coaxial speed reducers shares heavy loads to keep construction machine transmissions compact and strong.

A hose guide and guide plate limit hydraulic hose bulging near crawler travel motors, reducing damage while keeping movement smooth.

By switching excavation modes from hydraulic pump pressure, the controller balances traction and digging force to avoid overload and poor scooping.
