Anti-Theft Cycle Devices TRIZ Cases

Double engagement of fixing pieces and stopper protrusions prevents lever drooping under strong wrenching forces.

A scooter handle integrates a fingerprint module with an electromagnetic interlock to secure the inner and outer tubes.

A portable ring lock displays a visual indicium when the shackle is in the closed position.

Segmented helical surfaces distribute force across multiple spring coils, reducing stress concentration and preventing debris trapping in electronic locks.

A vehicle lid lock uses a control member with raised portions to index the hook, enabling compact housing integration.

A vehicle lock shutter uses a rotating operating member to move the cover.

A bicycle anti-theft device uses a ground-fixed groove and removable cover to secure the crank arm.

A rotary latch incorporates a disconnect feature that selectively decouples the pawl from rotation while maintaining axial engagement.

A hidden handlebar lock system uses internal detection and communication to notify users of the lock state.

Elastic locking claws apply holding force greater than device weight to prevent accidental falls while enabling single-step removal.

Dual electronic and mechanical cores actuate a common latch tongue, eliminating single-point failure risks from lost keys or system malfunctions.

Gate-driven forced guidance moves security elements perpendicularly, eliminating spring pretensioning and reducing structural complexity.

An oblique cam surface translates independent handle motion into latch displacement, resolving the trade-off between ease of operation and device complexity.

Perpendicular linkage reduces wear between pushing and engagement members, enabling keyless steering lock operation.

A figure wheel locking device uses interlaced rotating axes to drive detection members within a compact housing structure.

Segmenting the lock into a rotatable cable and wheel interaction component resolves the contradiction between security and ease of operation.

A door lock outer operational device uses a sliding block mechanism to control handle movement.

A motorcycle seat lock uses direct contact between the key cylinder and locking mechanism to release engagement without a wire cable.

Antitheft system locks hydraulic driving unit when driver exits cabin with ignition on.

Metallic reinforcing plate interposed between resin base and outer panel restricts handle turning end, reducing component count for assembly.

Segmenting the latch body from metal holding elements allows adjustable spring force, overcoming plastic material limits for higher vibration resistance.

A spring-loaded locking assembly deployed via an elongated pole secures a vehicle wheel from a safe distance, eliminating officer exposure to fleeing traffic.

A pile-free parking management system uses paired sensing units and portable locks to manage vehicle positioning without fixed infrastructure.

A remote server transmits user settings to a vehicle system for automatic component adjustment, eliminating manual setup when switching vehicles.

A drainage hole connects the storage recess to a retaining recess, discharging water from the steering stem housing to prevent accumulation.

An electromechanical locking system replaces manual keys with radio frequency signals, resolving security reliability versus device complexity.

A cylinder lock shutter mechanism uses a unified engaging device to release engagement via solenoid or magnet lock.

Segmented drive surfaces allow independent engagement by key or motor, resolving the conflict between secure locking and automated actuation.
