Non-Mechanical Controls TRIZ Cases

A modular swing-arm and electromagnetic delay mechanism adds timed unlocking to flat-push emergency door locks without modifying the original lock.

Motor current and bolt vibration signatures confirm true deadbolt engagement with the door jamb, avoiding magnet-defeatable reed switches.

Spring-loaded spindles center the lock body across varying door thicknesses while enabling toolless handing and protected electronics.

A lifting member and flexible strap spread impact force across the door frame, making forced entry harder than with a small-area deadbolt.

A linked deadlock and keyless lock unlock together through one actuator, cutting escape time while preserving door security.

A manual knob and motorized gear train share one lock linkage, so the door can still lock or unlock when motor power is off.

A latch bolt pre-centers the door before a swing hook engages, enabling self-locking with stronger tamper and burglary resistance.

A keypad-controlled lock replaces shared keys on jobsite boxes, cutting access delays, lost-key risks, and foreman-only access bottlenecks.

A passive movement sensor wakes position monitoring only during manual lock use, enabling event logging and notifications without constant battery drain.

A single lock body uses cam followers and a piston to secure both cart door and hatch, reducing key handling while maintaining access security.

A segmented bolt spanning the leaf and frame delivers smooth low-force locking while resisting pressure waves and shock.

A position-sensing rotary seat lets the lock verify a turn sequence and open even when both the sensing card and key are unavailable.

An electromechanical spindle and lever mechanism enables smooth motor-assisted sash tilting while preserving independent manual tilt-turn operation.

A rotatable anchor body and latch let a powered sliding door open mechanically from the private side during power failure or evacuation.

Replacing the mechanical key cylinder with wireless electronic latching removes a drillable attack point while improving corrosion resistance.

A wake-button lock shifts between hibernation and communication modes to preserve battery life while keeping remote status monitoring available.

A manual paddle handle and motor-driven lock bolt combine to fix slam latch keyless locking issues while preserving secure door operation.

A dual-shaft motor, worm cams, and spring-loaded plungers cut door strike power use while enabling fail-safe and fail-secure switching.

Dual restrictions, solenoids, and a manual lever keep overloaded storage doors unlockable when internal load blocks normal release.

A mobile-authenticated lock bar and latching assembly secures remote gates while improving intrusion resistance and access flexibility.

Motor self-heating and temperature sensing keep a wireless lock operable in low temperatures while preserving secure access and manual override.

Electromagnetic key sensing lets a retrofit smart cylinder unlock existing doors without batteries while adding secure access records.

A unitized actuator module lets one electric strike fit different latch assemblies while lowering mechanism complexity and improving locking reliability.

Dual spring-loaded magnetic bolts secure aircraft wardrobe doors with quiet operation, clean aesthetics, and built-in redundancy.

A controller, latch operator, and restrictor enable remote self-storage access override while reducing manual handling and infrastructure burden.

A retractable arm built into the wall or doorframe blocks forced entry, allows partial opening, and can trigger an alarm when pressure is detected.

A movable keeper latch and striker bolt cut unlatching force while preserving secure barrier retention for fast emergency egress.

Proximity-triggered access control decouples and recouples the exterior handle to simplify secure multipoint lock entry.

A compliant crank and spring coupling adapts to different push bar travel distances while cutting power use and eliminating separate dogging.
