Safety Arrangement TRIZ Cases

Magnetic sensors detect slide configuration changes without mechanical interference, preserving dynamic behavior and structural integrity.

Layer-by-layer assembly on a rigid profile reduces part count and eliminates springs, resolving the trade-off between reliability and assembly time.

A crossbow trigger safety unit uses spring-biased elements to lock the string hook and lever during loading.

Asymmetric grip geometry prevents unauthorized large-caliber mounting while enabling safe small-caliber training conversions.

Rotating the backstrap 180 degrees adjusts grip depth, eliminating lost interchangeable parts and improving field usability.

Magnetically conductive shield dissipates external magnetic fields, preventing unauthorized solenoid activation and maintaining lock security.

Distinct true and false gates in cylindrical tumblers prevent information extraction during picking attempts while maintaining reliable operation.

A firearm holder system uses embedded sensors to automatically detect weapon withdrawal and trigger immediate alerts without manual officer intervention.

A lever-coupled bolt catch mechanically links the selector switch to the bolt carrier assembly.

Replacing a wear-prone hinge with linear sliding guidance, this mechanism eliminates large clearance requirements while maintaining operational stability.

An intermediate sleeve with an integrated slope guides the firing pin to a safety position, preventing accidental discharge when the ram breaks.

A shell lifting device positions the automatic loading mechanism to insert shells into the cartridge chamber, reducing operator fatigue and safety risks.

A secondary safety surface on a safety element engages the sear to prevent accidental discharge from external forces.

A firearm uses image sensors and a computer to automatically identify targets and release bullets without manual aiming.

Relocating the L-shaped lever to a lower receiver protrusion prevents accidental spring overload and snagging during left-handed operation.

A magazine retention mechanism with interference flanges and sensors tracks physical ejection and re-engagement states.

Segmented left and right release levers allow one-handed actuation of the bolt catch, resolving single-hand operation constraints.

A firearm security device uses a fixed plate, movable plate, and trigger guard stud to hold weapons securely.

A dummy round records removal events to enforce chamber loading rules and prevent accidental discharges.

A redundant second sear halts forward striker motion to prevent hung striker conditions and unintended discharges in firearm trigger assemblies.

An open cam mechanism maintains the breech block in a closed state after firing, preventing harmful gas discharge while enabling simple mode conversion.
