Building Locks TRIZ Cases

Segmented cover cap and ring eliminate frame scratches during assembly while hiding gaps.

Flat edge strike latch plate removes protruding lips to eliminate injury risks while maintaining reliable bolt retraction.

A shoot bolt mechanism engages a receiver to lock sliding fenestration panels in place.

A double-leaf door lock uses a guide slot and actuating pin to retract the deadbolt for panic release.

A corner drive assembly transfers motion between window lock bars via a sliding spring, reducing friction and adhesive interference.

A refrigerator locking device uses a tongue and clamping block to secure cabinet doors.

A locking mechanism secures a self-steering axle wheel while an indicator system confirms the locked status.

A spacer with a rotation preventive mechanism interfaces the steering column and combination switch.

Segmented wire ropes pulled through intermediate node blocks ease manual operation of the bed cover lock while preventing sidebar tilting.

A pull box kit secures wire theft using keyed fastener nuts and a J-bolt anchor system.

A resilient positioning hook deforms to disengage a pin from a contact surface, protecting internal components from mechanical stress.

An automatic hidden latch structure retracts its post via a transmission mechanism, preventing floor damage and simplifying operation.

A locking device with multiple hooking means engages a strike plate to increase contact points and mechanical strength.

An integrally molded tilt latch uses a plunger assembly to protect the spring from distortion while a weatherseal lip blocks dust ingress.

A portable door lock uses a pivoting locking bar stored in a compact housing for secure engagement.

A unitary latching structure holds a cover in a closed orientation while remaining outside the equipment volume.

A flush rosette fitting uses a push-push mechanism to secure the cover plate directly against the substructure.

A vehicle door check link mechanism limits door opening to an intermediate position using a latch member.

A panic bolt crash bar pivots about a longitudinal axis to activate the lock mechanism.

A dampening spring absorbs impact forces to protect anchor points from dislodgement during forced entry attempts.

Hydraulic cylinder throttles recoil forces via fluid passages, resolving instability during misfires and premature firings.

A locking astragal merges fastener covers and stiffeners into the main body to eliminate loose parts.

Exterior handle actuation pivots the pawl member away from the striker, enabling single-handed door release without reaching inside.

An actuation device expands extension members within an elevator door lock to block unauthorized access while allowing maintenance.

A cam lock cover contour interacts with the actuation to prevent closure when open.
