Winding Mechanisms TRIZ Cases

Segmented pulleys prevent cable binding at angles by maintaining 90-degree contact, reducing wear and improving recovery efficiency.

A towing winch deflection pulley system guides the cable while a sensor detects contact force on a pivotable support.

A motor-driven handheld hoist moves loads along a cable using a cinch brake assembly for secure positioning.

Cascade brake engagement prevents load skewing during parallel heavy lifting operations.

Instrumented fairleads monitor cable orientation and load to stabilize pipelayers on steep terrain without adding counterweight complexity.

A winch clutch mechanism reconfigures between radial and axial positions.

Independent software, hardware, and mechanical layers prevent harm from winch abnormalities without increasing overall system complexity.

An automatic capstan selects gear ratios via a rotating inner crown to resolve manual switching complexity.

Paired sheaves on a rotatable support vary contact angles to control rope tension, reducing unnecessary bending cycles and space requirements.

A double-speed electric winch integrates two planetary gear sets within a single gearbox to enable convenient speed adjustment.

Active rope guide driven by shared motor reduces friction and wear while clutch mechanism protects transmission from excessive loads.

Segmented chain link body enables adjustable positioning of hoisting rope guide components, resolving installation complexity and rope wear trade-offs.

Active motor locking holds loads at zero speed, eliminating transmission damage from over-braking.
