Building Locks TRIZ Cases

Modular gear rack segments allow variable backset lengths without altering locking position precision.

A locking device latch bolt uses a transversely projecting pin and displaceable blocking element to constrain displacement paths.

Tapered keeper-engaging regions and angled walls guide the latch bolt to prevent overshooting, reducing impact shock stress on operators.

A cover plate with conically beveled threaded holes distributes lateral impact forces across a larger area to enhance structural integrity.

A window lock uses a movable abutment to bear against the frame, securing the sash in place.

A rod lock emergency release decouples the drive rod from the actuator to unlock multiple locking mechanisms with a single operation.

Spring-biased vertical slide catch secures wire enclosure doors against pet escape while allowing simple owner access through a single finger pull.

Actuator disengages latch during sash closure to prevent window frame damage from impact.

A locking mechanism uses a coupling device to separate automatic and tight-closing functions via a cylinder.

Adjustable arm inclination and length enable a single panic bar mechanism to fit multiple lock configurations without redesigning the structure.

Inverting the latch mechanism rotates the locking surface outward, preserving internal component placement area while maintaining secure attachment.

A spring-biased latch blocks plate movement to prevent accidental circuit breaker switching.

U-shaped aluminium profiles compress sliding pivoting door panels to eliminate gaps, preventing water infiltration while maintaining smooth pivoting operation.

A closing and opening device uses elastic means to switch engagement positions for secure panel closure.

A dynamically adjustable strike plate repositions a bolt receptacle to maintain tight clearance and reduce vibrations in moving structures.

Segmented drive bolts with a reversing gear allow sash tilting while maintaining secure locking reliability.

An emergency unlocking device segments from the primary actuator to allow self-release when trapped, resolving reliability risks in one-sided access.

Extruded metal strip with longitudinal webs resists tool-based levering on window frame locking bars while maintaining slim profiles.

A rotating modular user interface exposes internal gaming machine components without tools.

A transversely corrugated plastic spring integrally molded with a latch bolt provides reliable actuating force for tilting window sashes.

A rotatable lock pin uses a cam track to engage a guide, securing the pin to the safe body.

Integrated swivel bolt prevents unauthorized lifting by engaging a guide rail pin, reducing component count while enhancing burglary protection.

A camera housing draw latch secures two pivotally coupled portions using a rigid plastic mid-linkage and bent wireform.

Segmented locking units with distinct drive mechanisms maintain security reliability when warping blocks one lock.

Flexible ramps on a spring-loaded arm guide the locking pin from tilted to closed positions, preventing catches and simplifying structure.

An inward-extending flange secures a decorative trim surround to a base plate, enabling aesthetic customization without replacing the entire hardware assembly.
