Building Locks TRIZ Cases

Outer chamber locking elements coupled to a push rod resolve space conflicts with corner drives, enhancing stability without extra actuation.

A hinge locking device uses a mounting plate and reinforcement gusset to secure a door panel against a frame.

Curved slot geometry in a rotating camming element retains the latch in an unlatched position without depressing the push bar.

Two transverse gears drive a single slide to accommodate different lever positions, eliminating specialized hardware and reducing production costs.

A multi-point locking system couples a door to its frame at three locations using solid steel components.

A door lock extender projects the latch engagement point outward from the control panel box door to maintain secure locking.

Segmented latch bars with universal T-shaped connections resolve trade-offs between manufacturing simplicity and adaptability to various locker heights.

A self-adjusting latch mechanism moves along a rod to compensate for manufacturing variances in protrusion spacing and dimensions.

An adhesive door stopper employs a pressure spring to retract its movable head, eliminating manual removal and preventing surface damage.

A parking door assembly with connector holders organizes fiber optic connectors on a distribution panel.

A strike plate uses a ramp-shaped leaf spring to guide and support the bolt within a locking rod fitting.

A locking member uses a heart-shaped speed regulation path to fluctuate and slow an entering rod before engagement.

A door latch mechanism uses an oblique cam surface to translate handle movement into latch displacement.

A door-equipped housing features a flexible part that bends to climb over a projecting portion, enabling smooth operation.

Segmented locking balls engage handle grooves to simplify assembly while maintaining high load capacity.

Interlocking modular base sections eliminate custom cutting and reduce storage complexity for variable door heights.

An active vehicle seat controller disables operation upon detecting security threats.

A length adjustable door lock uses a sliding lock bolt within a housing sleeve to adapt its dimensions.

An actuator maintains a spring latch bolt inside a bolt housing to prevent sudden contact with a strike plate and eliminate latch noise.

A pivotable latch arm secures outward-hinged doors without floor modifications.

A modular robotic arm with interchangeable gripping tips installs diverse carpentry fittings on frames.

A motorized steering lock uses a parallel bolt to reduce radial space requirements.

A wear protection element made of hardened material supports the locking frame, preventing contact area deterioration and maintaining reliable locking function.

A compression latch uses a cam surface to guide shaft movement for secure panel engagement.

A pivotable cover blocks access to the drive surface until engagement, resolving ambiguity in latched states.

A reinforced deadbolt socket assembly uses a kinematic brace to maintain window security.

A furniture drawer locking mechanism uses horizontal pivot filling parts to block pull-out movement of adjacent drawers.

A disassemblable hinge uses a rotatable catch to lock and release the hinge member within a defined space.

Segmented fastening member and elastic bias mechanism prevent wear at snap fit lock connection points during frequent opening cycles.

Masking dots create rough contact layers that scatter light, resolving the trade-off between high extraction efficiency and complex manufacturing processes.

Scissor-driven drop seals and wall-mounted resilient members block sound and pathogens without impeding door movement.

A spring-biased detent engages housing orifices to anchor the shank, accommodating varying door panel thicknesses.

A handle lever toggle mechanism secures pump closures through precise hinge alignment and spring biasing.

A trackless sliding door pivots panels outward from a header member using integrated carrier bars and lock members.

A motorcycle key cylinder operates separate locking mechanisms via dedicated cables, eliminating redundant unlocking hardware and reducing device complexity.

A sash window lock cam rotates within a housing to engage a keeper catch via an elongated sweep arm channel.

A lock striker uses a tool to rotate retaining elements for rapid extraction without removing the striking plate.

Integrated spring unit holds and resets the handle, reducing assembly complexity.

A sliding door locking mechanism uses mechanical conversion means to push panels together for sealing.

Segmenting latch and keeper assemblies resolves the trade-off between shear load capacity and device complexity.
