Mechanical Machines/Dredgers TRIZ Cases
- Trench Cutter Switchover Mechanism for Cutting Wheel Flushing
A trench cutter switchover mechanism directs discharge pump fluid flow onto cutting wheels to flush adhering soil material.
- External Swing Damper for Rotary Joint Friction Disc Replacement
An external swing damper replaces glued linings with replaceable friction elements and mechanical spring pressure, eliminating adhesive failure contamination.
- Percussion Tool Impact Energy Control via Seismic Feedback
A control unit adjusts striking piston energy using real-time seismic data to protect nearby structures.
- Work Machine Notification Control for Excavation Context
A work machine controller adjusts operation support notifications based on terrain profile comparisons.
- Excavator Boom Control for Vibration Suppression
Adaptive current control suppresses hunting during dump operations while preventing lever vibrations in excavation mode.
- Dump Cylinder Speed Control via Piston Position Feedback
Position sensor feedback enables the controller to reduce hydraulic flow before impact, preventing component wear during rapid extension.
- Ultrasonic Sensor Cone Width Tuning for Vegetation Interference
Dynamic cone width adjustment isolates ground echoes from vegetation clutter, ensuring accurate milling depth measurements.
- Swivel Bucket Assembly Multi-Axis Maneuverability
A swivel bucket assembly rotates and pivots independently via a dedicated mounting mechanism.
- Portable Water Spreader Tiltable Tank for Precise Road Base Application
A portable water spreader uses a tiltable tank and spray heads to distribute liquid across work sites.
- Attachment Coupler Hook Mechanism for Foreign Matter Protection
A cam-driven hook advances into the U-shaped arm opening to secure the attachment pin during operation.
- Skid Steer Rearview Mirror Offset Bracket Design
Offset support arm positions the mirror above the lift arm to provide clear rear visibility without obstructing the tail swing path.
- Soil Recycler Fork Receiving Device Transport Stability
Spaced recesses in the housing prevent tilting and slipping during lifting fork transport, eliminating ropes and reducing center of gravity instability.
- Steering System Torque-Based Mode Selection
Controller selects steering modes based on transmission output torque to minimize track slippage during heavy load turns.
- Construction Equipment Banana Boom Utility Pole Placement
A banana boom extension assembly couples with utility line poles for precise placement and removal operations.
- Compact Excavator Fuel Tank Side Observation Window
Side-mounted fuel tank level gauge and cab observation window enable visual oil checks in compact excavators without compromising space.
- Bulldozer Steering Brake Thermal Load Control
A control unit tracks half-engagement duration of bulldozer steering brakes to suppress thermal loads and prevent damage.
- Adjustable Wheel Arms for Floor Conveyor Gauge
Segmented frame plates and universal wheel arms adjust the gauge to accommodate various vehicle sizes without increasing material storage variance.
