Mechanical Machines/Dredgers TRIZ Cases
- Tilting Screw Actuator Layout for Misalignment-Tolerant Construction Equipment
A tilting threaded rod lets electric actuators absorb framework deformation and tolerances, reducing screw damage without heavier structures.
- Excavator Blade Prism Support Column for Interference-Free Measurement
A rotatable prism support column on an excavator blade enables precise total-station measurement while avoiding work-device interference and manual removal.
- Excavator Dual-Display Guidance Layout for Clear Forward Visibility
Separating bucket tip guidance from terrain imagery helps excavator operators keep critical data visible without blocking the forward view.
- Excavator Guide Screen Switching by Detected Work Pattern
Sensor-based work pattern detection keeps excavator guide screens aligned with actual excavation, travel, and embanking tasks in real time.
- Hydraulic Oil Tank Layout for Side Access and Tool Storage
Raising the hydraulic oil tank creates a side opening for easier waste-liquid draining and secure tool storage in compact excavators.
- Work State Estimation for Predictive Control of Self-Propelled Vehicles
Onboard sensors classify vehicle work states to automate engine speed and implement control, cutting fuel waste and operator fatigue.
- Construction Machine LiDAR-Camera Sensing for Fast Accurate 3D Mapping
Rapid dual-axis LiDAR and camera fusion improves terrain modeling and obstacle detection for safer autonomous construction machines.
- Work Machine Display Layout for Blade and Ripper Camera Views
Divided screen regions switch between blade and ripper camera groups, increasing visible information without degrading each image.
- Wheel Loader Traction Control on Slippery Surfaces
Dynamic traction limits based on friction, vehicle weight, and excavation state help wheel loaders reduce slippage and keep digging efficient.
- Loading Machine Bucket Positioning for Excavation Start Posture
Automatic swing-body and bucket posture control repositions the bucket for the next excavation cycle while avoiding undercarriage interference.
- Spring-Biased Operator Platform Interlock for Dumper Movement
A spring-biased platform and limit switch stop dumper travel unless operator weight is present, while ignoring small dropped items.
- Magnetic Bucket Tooth Locking Pin for Fast Dirt-Free Removal
A movable magnet locks a bucket tooth pin without exposed fasteners, cutting dirt buildup and speeding installation and removal.
- Compact Loader Arm Path With Wide Tracks for Tight-Space Lifting
Oversized tracks and a controlled vertical-lift arm path let a narrow compact loader maneuver in tight spaces without poor ground load distribution.
- Work Machine Drive Braking Using Regenerated Power Transfer
Regenerated braking power from the travel drive is routed to storage or the work motor, avoiding braking resistors and reducing friction brake wear.
- Excavator Bucket Trajectory Control at Construction Plane Bends
Segmented control switches target working lines near plane bends so the bucket follows horizontal-to-slope transitions more accurately.
- Excavator Attachment Pressure Control for Back Lift Stability
Hydraulic pressure relief in the boom cylinder limits attachment motion during automatic digging to reduce back lift and improve stability.
- Work Machine Imaging Control for Automatic Progress Recording
An onboard camera captures site images only when a preset subject region is in view, reducing manual progress recording on work machines.
- Shovel Cab Display Layout for Continuous Surroundings Visibility
A split cab display keeps camera views visible while menu screens are open, helping shovel operators maintain awareness during settings access.
- Power Rake Drum and Retractable Blade for Single-Pass Grading
A retractable front blade and flexible barrier let a powered rake grade and rake in one pass while reducing wet-material clogging.
