Mechanical Machines/Dredgers TRIZ Cases

A split control architecture lets work vehicles add tilt and rotation attachments while preserving precise multi-axis tool motion.

A ring antenna in a dielectric-lined pipe measures slurry concentration under saline conditions while integrating with velocity metering.

A rotary feedthrough replaces hose routing in mobile machine attachment couplings, maintaining reliable pressurized media supply during rotation.

A dual rotating mechanism repositions the work device to cut transport overhang, avoid narrow-space interference, and stay stable under high loads.

A rotating eccentric runner support keeps the cutter-centered path precise, improving milling depth control while containing debris.

A U-shaped flexible hydraulic pipe inside a telescopic arm reduces pipe damage during extension while keeping arm width compact.

A seat-accessible auxiliary switch lets articulating tractor operators change hydraulic functions more easily while reducing control complexity in tight spaces.

A rotating sensor stay and radial engagement groove keep magnet-to-sensor spacing stable despite backlash, improving boom angle detection.

A fork-shaped stick connection moves the mounting device closer to the axis, cutting breakaway force and expanding attachment swivel range.

Movable detector spacing, elastic support, and air nozzles improve radiation measurement and detector protection in confined demolition work.

Real-time display icons track housing and boom swing relative to the undercarriage, helping excavator operators avoid obstacles.

A rotary joint adds out-of-plane motion to the suction tube, expanding reach while avoiding collisions and preserving coarse material flow.

Sensors, control, and a restricting member stop bucket rotation before it hits nearby machine parts, reducing accidental damage.

Aligning bucket, stick, boom, and platform hinge points in one vertical plane cuts bending moments, removes extra reinforcement, and extends service life.

Sets an allowable work range from projector-receiver position data to avoid beam blockage and reduce interruptions in machine operation.

Variable relief pressure tied to lift linkage position lets skid steer loaders raise heavier loads while staying within tipping limits.

A curved suction-head wall and high-speed water feed reduce flow losses and improve deep-sea mineral deposit pickup and transport.

Sensors and closed-loop control predict unwanted machine movement and apply boom, bucket, or track corrections to prevent mis-cutting and mis-dumping.

A sacrificial liner inside the spoils transition tube deflects abrasive debris into the vacuum port while protecting the microtrencher housing from wear.

Dynamic swing control keeps the excavator end attachment following the slope surface in contact, improving shaping precision and work efficiency.

A flexible, tiltable bearing lets the gear wheel move under impact, protecting the trench cutter gearbox while saving installation space.

A 360° rotating control platform and 180° excavator rotation remove seat changes, expand digging range, and improve operator visibility.

A preset entry-prohibited surface restrains bucket motion before the target work surface, preventing unintended over-excavation.

Image-based state detection corrects tip-attachment release position so work objects are placed accurately despite shape and position variation.

Engine load feedback automatically raises or lowers a tractor blade to keep engagement in range, cutting passes and fuel waste.

Multiple upper-house cameras are stitched and shifted by swing angle and travel direction to keep the machine's forward path visible.

By omitting selected target points and recalculating timing, this case keeps attachment motion predictable while reducing unnecessary work machine movements.

Electric cylinders, drive motors, and sensor-based grade control replace hydraulics to improve skid steer grading precision and avoid oil leaks.

Reward feedback from actual and target position curves lets excavators learn combined-operation control with less manual tuning.

Simple position and velocity sensing automates excavator digging and dumping cycles, cutting operator fatigue and sensor complexity.

Void fillers, bushings, and spring clips keep grader tool bits secure while reducing packing, washout, and removal effort.

Buffered NFC attachment IDs are stored and selected only after linkage attachment, cutting processing load while improving recognition accuracy.

An attachment plate lets a grapple engage a bucket, cutting attachment swap downtime while handling both large objects and particulate material.

Event-driven soil sensing on an excavator captures site and position-linked soil data only when conditions change, reducing storage load.

Replaceable suction box covers let trench cutters shift opening shape and position for different soil conditions without changing the base body.

Error-based assistance shifts control between operator input and machine correction, improving work device orientation near the target.

Adjusts both path and timing in work-machine attachment trajectories to avoid abrupt speed changes while preserving work accuracy.

A coaxial pivot and laterally offset piston give backhoe buckets precise lateral tilt for grading on uneven terrain with less downtime.
