Mechanical Machines/Dredgers TRIZ Cases

Articulated lateral wings and spring-loaded lower sections let a road scraper follow uneven pavement, vary width, and clear obstacles in fewer passes.

LIDAR terrain mapping and dynamic blade-depth control help bulldozers grade soil more precisely while reducing operator error and rework.

Symmetric reinforcing members strengthen grader rotary frame bends, easing stress concentration without adding overload-causing weight.

Multiple self-contained drive pods feed a central gearbox, delivering excavator horsepower while easing transport, repair, and power scaling.

A swivel joint adds out-of-plane motion to a suction excavator tube support, expanding reach while avoiding hose collisions and damage.

Adjustable slotted brackets simplify excavator boom-cab sensor alignment while keeping magnetic angle detection accurate and reliable.

Real-time status feedback alerts cabin and remote operators to each other's inputs, reducing unexpected machine activation and confusion.

Controller-led shutdown sets the parking brake, shifts to neutral, and grounds implements to prevent unintended grader movement and interference.

Sliding grip plates and actuators replace rust-prone coupling pins to fit varied attachment tools while stopping lateral movement.

When bucket position functions compete during slope formation, priority control prevents conflicts and keeps excavator operation smooth.

Visual feedback sets the bucket start position where it partly overlaps the excavation target, improving accuracy as the contour changes.

A multipart side plate lets worn ground contact sections on mounted earth removal equipment be replaced separately, cutting maintenance effort.

Interchangeable spar and dangle head modules cut boom changeover time while handling different head configurations, loads, and torque.

Magnetic sensor mounting and protection simplify excavator boom-cab angle calibration while maintaining accurate rotation detection.

A chain or belt-driven support body gives vehicle-mounted tools full-width horizontal travel at constant speed while staying compact and protected from dust.

Operation is restricted when the displayed camera view is unsuitable, helping remote work machines avoid unsafe control conditions.

A bracket and damping-rubber mounting layout isolates boom access covers from vibration, reducing cracks, deformation, and dust or water gaps.

A pilot-controlled hydraulic circuit opens check valves to combine blade float, anti-drift, and anti-sink control for stable machine operation.

A guided release block keeps the latch locked until the jaw disengages, preventing excavator attachment ejection and hydraulic overload damage.

An adjustable locking stop compensates for tolerance, wear, and deformation to secure crane tool couplings while reducing movement, loads, and noise.

A separate displacement carriage and lifting line let the hammer fall freely for stronger impact while reducing wear, vibration, and breakdown risk.

Bucket angle is used as a reference to set the target digging surface automatically, cutting excavator setup time and manual configuration effort.

Varying wing shroud curvature and added material spread wear across GET contact zones, extending service life and reducing replacements.

Threshold-based boom and steering control standardizes pile approach digging, cutting vehicle stress, fuel use, and operator dependence.

Three nested boom members driven by one actuator extend vacuum hose reach while limiting sagging, debris buildup, and plugging.

A plug-in steering wheel can be removed to clear the operator's forward view, while joystick steering and speed limiting maintain safe machine control.

Dual counterbalance valves lock circle drive motion and block reverse motor drive, reducing slippage, heat, and gear wear in grading machines.

By monitoring boom, stick, bucket, and lever states, hydraulic control cuts excavator impact and vibration while preserving work efficiency.

When a fault is detected, the controller blocks work implement operation while allowing travel, preventing continued work and enabling safe relocation.

Acceleration feedback adjusts blade propulsive angle to match actual travel direction, easing operator control on varying road surfaces.

A stored reference heading lets remote implement commands stay intuitive even when the machine changes orientation, reducing operator confusion.

Boom cylinder force and ground acceleration are used to measure bucket load accurately during wheel loader travel despite vibration.

Retaining spring clips, bushings, and void fillers prevent packing, wear, and bit rotation while allowing easier tool bit removal.

Abnormal position regions around a target part help automatically operated work machines detect motion deviations for safer, controlled operation.

Kalman-filtered kinematic estimation improves excavator bucket tooth tip 3D coordinates despite system and sensor noise.
