Padlocks TRIZ Cases

Asymmetric cylinder core positioning reduces manufacturing complexity while maintaining secure loop attachment reliability.

A padlock mount integrates a saddle and recessed cavity to restrict shackle rotation and protect the lock body from external forces.

Linear lid displacement engages a positive lock via the hinge, eliminating complex push-button mechanisms and reducing device complexity.

A padlock drive element uses a prestressed locking component to hold the flexible shackle in place during unlocking.

A flippable cable lock uses an X-shaped twistable cord to distribute twisting forces evenly across the locking assembly.

A locking device uses spaced plates and independent padlock bars to secure a sliding member against unauthorized access.

Integrating the cam with the lock cylinder reduces overall length and manufacturing complexity while maintaining reliable locking functionality.

A laminated padlock lock core assembly constrains cipher wheel positions through rectangular notches and limiting chucks.

A padlock assembly uses a rotatable shield to cover the lock body and shackle when locked.

A hook lock uses a pivoting locking finger and latch to form a secure loop.

Segmenting the lock body allows independent cylinder removal, preventing loss of small components during maintenance in poor lighting.

A hook lock uses a shared latch to coordinate combination and key mechanisms for secure engagement.

An accessible flange allows users to release the lock cylinder without disassembling the padlock, simplifying maintenance.

An elastic member presses a clamping boss against the zipper hole, preventing accidental opening while allowing intentional release.

Transversely movable securing element engages lock housing opening via compression spring preload, eliminating tool-dependent attachment complexity.

Segmented core rotation aligns reconfiguration channels with casing openings to replace pins without detaching the core, reducing rekeying time.

A combination padlock uses segmented housing parts that axially separate and rotate to expose visual formations.

A padlock integrates a combination dial system and a key override mechanism to secure luggage while enabling rapid security inspections.

Segmented cam recesses enable shackle removal without weakening structural integrity, allowing one lock to fit multiple shackles.

A combination lock spindle uses axial movement to align locking protrusions with dial recesses for secure operation.

A stamped brass insert with question-mark tines supports dials and blocks the member to resist attacks while preventing corrosion trapped in narrow throats.

A combination padlock and resistant mesh receptacle prevent theft by eliminating key management while resisting cutting tools.

A padlock featuring a removable shackle and pivoting rear cover enables quick size changes for versatile locking applications.

Segmenting the locking mechanism isolates pin channels in the cylinder core, preventing drilling damage to the finished lock body.

Recesses and projections in the shackle passage block shim rotation, preventing mechanical attacks on the preloaded locking member.

A riveted lamella padlock body uses a removable end lamella to secure an exchangeable lock cylinder via a through-rivet fastening mechanism.

Stamping lock plates without external web eliminates material waste while integrated fasteners secure seams against tampering.

Segmented protective sleeve covers the straight shackle section to prevent bolt cutter jaw engagement and maintain lock integrity during cutting attacks.

Segmenting the lock body allows core replacement without discarding the shackle, reducing expenses from whole unit failure.

An integrated cam mechanism locks the link directly, eliminating padlock weight and complexity.

A compact padlock uses a rotary bolt with a tangential blocking section to engage the second shackle leg while driving a radial element against the first leg.

Coaxial through bores and U-shaped channels in the housing secure gear shafts to prevent unauthorized access.

Segmenting the lock cylinder from the padlock body allows users to change security levels by replacing only the cylinder, avoiding full unit replacement.

Simultaneous laser engraving on wide and narrow padlock housing surfaces resolves precision instability caused by paint coatings, ensuring durable markings.

Segmented cable locks secure packages against theft while avoiding bulky chest designs, allowing compact storage and easy relocation via dynamic anchor points.

A two-wheeler lock applies a hardened protective device on the fastening section to prevent cutting attacks while reducing overall weight and production costs.

A combination padlock uses a claw mount to enclose the rocking claw and dial wheels within a protective cavity.

Coaxially aligned combination and key mechanisms in a single housing prevent forced opening via deadbolts while blocking contamination.

Multi-bend shackle aligns signage parallel to fence, resolving angled readability issues.

Composite strap construction with a freely moving inner cable resolves the contradiction between portability and cut resistance.

A chain lock featuring a spherical body and linkage chain that winds around the core for compact storage.

A cable lock uses a shaft and fixed cam to release two independent cable ends via combination dials or a key override.

Segmented locking elements engage straight and bent shackle feet to prevent rotation, enhancing structural integrity against high pull forces.

A padlock security enclosure uses a nested sleeve to restrict keyhole access.

A padlock actuator integrates a torsion spring to co-rotate the key cylinder while maintaining axial alignment within the lock body.

A zipper lock uses blocking plates and a latch-control plate to secure pull tabs.
