Mechanical Machines/Dredgers TRIZ Cases

Drive current is applied before engine start to clear foreign matter from a hydraulic pilot solenoid valve without unintended actuator motion.

Sets construction machine work areas from design data to keep restriction boundaries aligned during travel and avoid entry into prohibited zones.

Position feedback and current adjustment reveal actuator brake holding capacity, helping prevent load drift during power-down.

Lateral fastening on longitudinal rack frames avoids welded plate planarity loads, protecting construction machine batteries and speeding assembly.

Standardized front and rear axle units let one mobilization setup fit different work implements for faster road transport and easy attachment.

A lateral battery rack replaces planar mounting to absorb welding deformation, reduce tensile load, and speed construction machine assembly.

Inner ribs tied to the lower plate spread arm cylinder load, suppressing bracket stress during high-elevation excavation with full retraction.

Drive-load feedback builds a soil-nature map and corrects bucket commands, helping semi-automatic excavation stay precise across depth and soil changes.

Predicted work-device paths and prohibited areas let loaders adjust swing and lift motion to avoid transporter contact without slowing normal loading.

Inclination-based control suppresses false ground detection during scooping, avoiding unnecessary braking and rear obstacle alarms.

Color-changing icons indicate when empty-bucket reference correction is allowed, helping excavator operators avoid weight calculation errors.

Saved torque is validated against boom, arm, and bucket state so brake release can hold position and prevent falling or sagging.

Validating saved torque from boom, arm, and bucket status helps prevent excavator falling and sagging when the brake is released.

Object detection and video approval let a work machine start remotely only when nearby workers are clear, improving cold-region startup safety.

A changeover valve routes the highest circuit pressure to the locking drive, securing construction machine attachments more reliably.

Front-side keyhole locking secures a trailer hitch to an excavator dozer blade without rear access, improving attachment ergonomics and safety.

Compares motor torque with standby torque from boom, arm, and bucket status to release excavator brakes without falling or sagging.

Weight- and position-based standby torque control sets brake release timing to prevent excavator boom, arm, or bucket sagging.

A rover latching interface secures and moves modular or large lunar payloads while adapting chassis height and stance to uneven terrain.

Fused roll, pitch, and gyroscope data from dual IMUs improve real-time yaw articulation estimates for more precise earthmoving control.

An adjustable pivot-pin layout keeps fuel cylinder rotation accurate despite part variation while freeing installation space with assisted single-member support.

A relative-angle display helps excavator operators compare bucket bottom inclination with target topography for more precise digging.

Accumulator-pressure feedback adjusts boom regeneration valve opening to keep descent speed aligned with operator input while recovering hydraulic energy.

Positioning a 3D measurement sensor beside the headlight helps articulated work machines keep accurate target positioning during excavation and loading.

By lowering engine speed before low-load attachment work begins, this excavator cuts wasteful energy use while preserving power for heavier tasks.

A hybrid electromechanical-hydraulic actuator boosts peak force while keeping distal working-element actuators smaller and lighter.

A cable-linked pedal and inching valve on the floor frame improve mounting flexibility, cut vibration, and simplify cleaning.

Electrical actuators and a rear battery layout replace hydraulics to improve lift, tilt, and track control while reducing maintenance.

An electric motor and link mechanism replace hydraulic blade lift, cutting system complexity while extending blade travel with lower torque demand.

An electric motor and link mechanism raise and lower a dozer blade while reducing hydraulic complexity, torque demand, and mounting space.

Load-threshold control distinguishes excavation from leveling in wheel loaders, preventing unintended autonomous digging with standard buckets.

Set swing pause and limit points using obstacle and attachment sensing to prevent upper-body over-rotation and collisions.

Two opposed speed reducers share load through a differential, boosting overload strength while keeping construction machine drive transmissions compact.

Restricting setting changes when translational and rotational inputs overlap helps work machines avoid accidental equipment setting errors.

Server-side transmission control and machine-status acceptance logic simplify updating working device settings on connected machines.

Stored swing angle data lets the controller resume machine control within a valid swing range when swing structure position information is lost.

Travel restraint is applied only toward a detected object's direction by combining sensor results with revolving angle, reducing operator annoyance.

A vertical motor-pump layout frees frame space for a larger battery in small electric excavators, extending operating time.
