Winding Mechanisms TRIZ Cases
- Impact-Drill Winch Attachment for Low-Strain Heavy Lifting
An impact drill drives the winch drum to lift heavy loads with less strain, while auto-locking holds the load safely at height.
- Active Rope Guiding for Low-Angle Hoist Drum Winding
An axial-force rope guide compensates rope angle at the drum, cutting torque, wear, and sizing limits in hoisting systems.
- Rope Inspection Support That Follows Boom Tip Rope Movement
A movable support lets the rope inspection instrument follow horizontal rope motion, keeping detection stable during boom raising and lowering.
- Crane Load Hook Control Using Rope Tension Ratio Limits
By comparing tensions in two rope sections, the crane stops hook travel before unsafe lowering or collision near the deflection arrangement.
- Electro-Hydraulic Rope Winder for Even Drum Layering
Sensors and hydraulic actuation synchronize rope travel with drum rotation to keep wire rope layers even in compact forestry winches.
- Helically Grooved Drum Sheaves for Zero Fleet Angle Reeling
Varying the groove helix along a drum sheave keeps cable departure at zero fleet angle, reducing wear, twisting, and reeving space.
- Crane Winch Drum Layer Estimation Using Rope Length and Rotation
By comparing rope delivery length with winch drum rotation across boom orientations, this case improves wound layer estimation after rope cutting.
- Rope Drum Speed Control for Constant Line Winding
Feedback control adjusts drum rotation from real-time rope speed sensing to keep line winding constant as drum fill changes.
- Winch Drum Phase and LiDAR Monitoring for Precise Rope Winding
By combining drum phase detection with LiDAR distance sensing, this case improves winding layer and row detection with fewer components.
- Sailboat Winch Handle Magnetic Locking for Power Assist Control
Magnetic locking secures a sailboat winch handle without levers, while sensor and NFC pairing enable reliable power assist activation.
- Hoist Frame Clamping Layout for Load-Free Jig Extraction
A jig-supported hoist frame clamps the assembled structure while preventing cantilever load, reducing strain and damage during extraction.
