Mechanical Machines/Dredgers TRIZ Cases

Multiple tool holders distribute cutting across the disk cutter, reducing forces for mining and confined underground excavation.

This crane control case adjusts individual boom speeds to preserve head movement while avoiding actuator extremes and collisions.

Acceleration-based bucket control enables varied excavation patterns and fuel efficiency.

A controller compares target-surface height with the machine body to detect insufficient earth and sustain accurate placement.

A display-guided control process detects tilt rotator angle and stops rotation at the correct position for tool attachment.

A position-aware controller detects when the moldboard approaches the scarifier avoidance zone and adjusts movement to prevent contact.

Hydraulic vertical and rotary rotor adjustment lets one power rake handle grading, swales, and runoff areas across varied terrain.

Dual-switch signals secure work equipment locks while preserving emergency operation.

A work vehicle uses split shrouds and a rotatable heat exchanger to maintain cooling airflow while easing engine-compartment access.

A control valve sequences the retaining body and hydraulic manifold, securing the tool before hydraulic coupling.

This case combines cameras and distance measurement to show obstacle location, direction, and distance to operators.

Feedback-controlled swing and link movements start tool descent earlier, reducing arrival time while protecting the loading target.

This motor grader case uses discrete mounting brackets to balance cylinder loads, reducing circle bending, downtime, and servicing costs.

Dynamic box blade reconfiguration lifts the scraper and aligns its longest dimension with the vehicle for easier transport and storage.

Pivoting frames switch forward collection and back-dragging modes, reducing spillage while improving visibility around obstacles.

This case uses soil property data to adjust bucket excavation traces, balancing implement power, mobility, and fuel use.

A control unit maintains the bucket’s lowest point above target height during dumping to reduce collision risk in mine tunnels.

Cameras detect changing ground contours and reset the attachment’s finish point and trajectory for accurate excavation.

The excavator calculates work-area angle and turning radius to protect boundaries without slowing safe bucket operation.

Radial stator support and sealing stabilize the rotary joint while preserving fluid flow and resisting oil and dirt ingress.

A motor controller varies excavation speed and torque to maintain target power, reduce stalling, and isolate motors from vibration.

A central controller reallocates mining work machines using energy, delay, and flow data to sustain production plans.

This case uses control modes and feedback to position the excavator attachment, reducing data preparation and operator effort.

A single excavator screen lets operators select payload, lift, and machine guidance modes without cumbersome manual switching.

The display recommends work locations from current object-shape data, helping inexperienced operators choose excavation points.

A four-cable scissors grab uses simplified single-pass closing sheave routing to reduce complexity, maintenance points, and cycle time.

A dual-stage lift raises a grader snow wing higher while limiting mast interference with the cab.

Calculate attachment weight and center of gravity from boom pressure without extra bucket sensors.

This case uses spaced crowd bores, local wall thickening, and beveled weld grooves to extend dipper handle weld life.
