Building Locks TRIZ Cases

Multilayer composite materials resolve the contradiction between heavy security and portability in storage devices.

A latch uses flexible arms and a flat spring to secure hen houses against predators.

A locking device uses a rotatable tilting guide and restoring member to enable smooth vertical hook movement.

A retractable gangway supports an extended safety cage via cantilevered braces and lifting arms.

An automatic latching mechanism prevents impact damage during closure by engaging strikes before full contact, ensuring security without manual force.

Independent gripping elements in a sliding window lock prevent collision damage during incorrect operation while maintaining secure engagement.

An input surface on the locking element engages an actuating surface during closure to ensure complete locking before final panel contact.

An adjustable strike plate uses an eccentric cam to shift a lower plate, resolving immobility versus alignment trade-offs without protruding components.

A dial locking mechanism integrates into a prescription bottle cap to require a specific combination for opening.

Rectangular locking rod in lever latch reduces support body bulk while enabling in-situ length adjustment without disassembly.

A door latch assembly uses a movable extension member to hold a door in an open position.

A segmented pivot hook locking element engages recessed threshold parts to secure windows in closed or tilted positions without protruding hardware.

Dual bolts connect the slide and locking element, resolving assembly complexity while boosting burglary resistance.

A fabric roller blind coupling mechanism uses a rotatable hook and elastic means to retain the handle bar in the closed position.

A trim lock device transitions between locked and unlocked states to prevent unintended door opening during storms, maintaining reliable egress.

A mechatronic locking apparatus uses dual communication paths to enable secure bidirectional data exchange between a security key and lock cylinder.

Segmented access via an intermediary insert with anchoring flanges prevents theft while maintaining maintenance ease.

A roto-translation mechanism uses a sliding rod to lock a hung sash, resolving insufficient locking stability under strong wind conditions.

A latch assembly uses a spring-biased clasp lever to pivot against a closing panel tab for secure container engagement.

A ball joint fixing system accommodates relative movement between door plates to absorb levering forces.

A window locking assembly uses a gear mechanism to convert linear slide movement into rotary locking element motion.

A pivotable blocking element holds the latch bolt in a partially extended intermediate position within an espagnolette lock mechanism.

Selective metal members adjust magnetic force to balance hinge torque, resolving inconsistent opening forces from manufacturing tolerances.
