Self Acting Brakes TRIZ Cases

A dual-spring brake replaces oil dampers in automatic winding screens to keep braking torque stable across temperature changes and avoid leakage.

A spring-steel tolerance ring creates controlled friction in an external fall absorber, enabling resettable use and better weather durability.

A wedge-groove base, needle roller slide plate, and limit cover improve high-torque disc braking by preventing deformation and false locking.

Series magnetic armatures and dual friction discs raise shaft braking force in less space while simplifying control and reducing wear.

A tapered shaft and friction-disc brake locks the hoist drum as wear thins the discs, preventing unintended reeling under load.

Expandable brake shoes create viscous drag to prevent sprinkler turbine overrotation and keep speed control effective.

An adjustable pushing member balances brake distance and component impact by keeping robot joint brake friction within a safe range.

Adaptive brake blocks clamp the traction sheave and cut the safety circuit, enabling compact elevator emergency stopping with speed-based braking force.

An electromagnetic clutch engages a friction disk to slow steering rack motion during faults, helping rear wheels recenter and stabilize the vehicle.

An eccentrically pivoted braking arm stays off during casting and engages on deceleration to prevent backlash without cutting cast length.

A progressive modulating spring damps no-back brake chatter during aiding loads, reducing wear and maintenance in aircraft actuators.

Axially stacked armatures, springs, and friction discs raise braking force in less space while simplifying control and reducing wear.

A shackle drop brake holds a swiveling connecting part off the load, improving grip, alignment, and injury prevention during lifting.

A cured fastener in the pressure plate-electromagnet cavity shrinks brake size, preserves air-gap alignment, and avoids friction-surface contamination.

A knockdown lift uses modular trusses, clutch control, and overspeed braking to move loads safely over stairs where fixed access is unavailable.

A roller-based lever converts rotation into axial brake release, reducing manual force while keeping elevator brakes compact and movable.

A ball ramp no-back mechanism locks flight control surfaces in position and limits reverse torque to protect the actuator from overload.

A cam-and-notch indicator converts relative rotation into axial movement, reducing wear and contact stress for reliable torque limiter trip indication.

A normally closed magnetic brake stops the shaft during bit jams, giving handheld power tools faster protection and easy reset.

A wedge groove, elastic support, and needle roller slide plate prevent deformation and false braking in high-torque disc locking.

Magnetic self-adjustment shifts the floating bracket toward equal brake disc gaps, cutting axial force, one-sided wear, and brake response delay.

An external brake release passing through the housing lets a robot manipulator disengage its brake safely during power interruption.

A seize ring triggers torque disconnect when bearing centerline control is lost, limiting shaft damage without sensors or added electronics.
