Non-Mechanical Controls TRIZ Cases

Semi-automatic detection uses switch signals to verify mounting orientation and resolve left-right door ambiguity.

A trim lock device uses a rotating blocking member to visually indicate the locked state from the interior side.

A knob cylinder coupling mechanism uses a stepper motor and locking pin to transmit torque.

A magnetic slide latch mechanism enables quick service access to elevator control boxes using a portable external magnet.

A magnetic lock system uses an arc magnet and key magnet to control a lock element position through precise field interaction.

A bistable electromechanical actuator uses a spring system balanced against permanent magnets to hold the armature in end positions without power.

Segmented rotor assemblies enable bidirectional bolt control, resolving the conflict between outside security and inside emergency release.

Segmented side walls with movable parts allow quick access to potting troughs, reducing sealing compound volume and production time.

Rack and pinion gear moves locking bar horizontally to resolve complexity-reliability trade-off in garage door systems.

Magnetic field substitution replaces heavy mechanical blocks, reducing power consumption and actuator size while maintaining brute force resistance.

Alternating magnetic disks on the knob shaft return the lock bit to a neutral position, eliminating dead centers found in spring-based reset mechanisms.

Segmented locking and actuation modules allow rapid manual rotation of large façade elements during power failures while maintaining reliable motorized control.

A rotating bolt mechanism resists external impact forces by engaging a locking tab recess, eliminating vulnerability to linear motion trajectories.
