Elevators TRIZ Cases

A bi-stable magnetic brake actuator maintains elevator braking across variable rail gaps, reducing noise and wear while improving magnetic efficiency.

Surface contour scanning screens wall irregularities in stages to place boreholes where fastening components can be secured reliably.

Electromagnetic actuation moves biased brake members directly into guide-rail engagement, cutting linkage complexity and speeding brake response.

Permanent magnets replace springs in elevator safety gear actuation, cutting wear and maintenance while coils control disengagement.

An electro-mechanical screw and lever brake holds the elevator car at landings and tracks pad wear to reduce tripping risk and maintenance.

Residual current delays magnetic brake engagement so elevator emergency stops use staged braking torque with less jerk and smoother deceleration.

Permanent magnets and an electric coil replace spring actuation in elevator safety gear to cut wear, maintenance, and holding energy.

A force sensor on the brake mounting detects torque and drag, letting elevator motor control prevent car movement without load measurement.

Integrated reading units and point straightening improve lift guide alignment and surface accuracy while cutting production time and cost.

An electromagnet and spring trigger replaces rope-based governors, cutting complexity and easing wedge release from the guide rail.

An integrated magnetic brake and retention assembly simplifies elevator safety braking by cutting component count, installation time, and cost.

Using orthogonal magnetic actuation, this brake handles 0.5-3.6 mm guide rail gaps while reducing noise, wear, and braking loss.
