Mechanical Machines/Dredgers TRIZ Cases
- Hybrid Power Train for Tractor Scraper Regenerative Energy
A hybrid power train system uses an inverter circuit and energy storage device to manage electrical energy flow between traction motors.
- Semi-transparent Target Surface Display for Construction Landform Visualization
Adjusting transparency levels allows operators to see the underlying distribution map through the target surface, resolving visibility conflicts.
- Work Vehicle Steering Lever Control for Speed and Direction
Dual lever inputs enable single-hand direction and speed control, reducing foot coordination needs.
- Hydraulic Boom Cylinder Cavitation Prevention via Dual Pressure Source
A hydraulic boom cylinder connects a low-pressure fluid source to the head end to prevent cavitation and reduce frictional forces.
- Convertible Carriage with Floating Shaft for Uneven Terrain
A convertible carriage uses a shaft in an elongate slot to adapt to uneven terrain.
- Hoist Motor Control for Wire Rope Dead Wrap Safety
A controller regulates hoist motor torque based on wire rope wrap counts to maintain safe traction levels.
- Composite Articulated Arm Segment with Integrated Actuation Zone
An integrated composite segment uses filleted protruding zones to optimize mechanical resistance, reducing weight while simplifying the manufacturing process.
