Safety Arrangement TRIZ Cases

Thumb rest merges with safety selector switch assembly to improve handling while reducing device complexity.

A modular magazine well with a detachable front wall enables conversion between AR10 and AK47 configurations.

A conditional locking mechanism engages a handgun slide via a trigger sear and linkage bar to prevent reciprocation.

A lower receiver transfer bar catches the bolt to hold it open after the final round fires.

Locking device secures bolt stop lever in release position, keeping ejection window closed to prevent sand or sludge entry into the receiver.

Wireless power transfer sustains electronic accessories while unique trigger signatures identify users, resolving limited battery capacity constraints.

Optical detection replaces metal detectors to identify firearms and exempt personnel, eliminating entryway delays.

Biometric sensors on a firearm grip detect user mental state to unlock a trigger interlock, preventing unauthorized firing by unauthorized or distressed users.

Nested sensors verify identity before retracting a locking pin from the trigger bar, resolving unauthorized access risks.

Segmenting safety into independent slide and projectile locks prevents accidental discharge of nonconforming projectiles.

A bladed bolt stop lever pivots against spring force to restrict firearm bolt motion.

Segmenting the trigger guard from the barrel path allows dry firing practice without obstructing slide operation, preventing internal damage during training.

A trigger assembly uses a captured roller to provide rolling frictional resistance between sear surfaces.

A semi-automatic rifle design merges an M1-style barrel group with an AR-style lower receiver to enable modular assembly and accessory integration.

A rapid fire toy launcher employs dual triggered feeding from multiple magazine clips to enable continuous projectile discharge.

Smart firearm system replaces mechanical safeties with electronic authentication protocols, preventing unauthorized use while managing device complexity.

A firearm lock mechanism uses a spring and intermediate angle to drive hammer pivoting.

A garment holster uses magnetic docking to authenticate and position a video recorder, preventing accidental activation while enabling hands-free operation.

An actuated barrier component interrupts breech block movement through the ejection port to halt runaway firing in remotely operated weapon stations.

An RFID trigger lock uses a microprocessor and servo motor to authenticate users via wearable keys.

A biometric locking system uses a dual assembly to transition between safe and fire positions.

An interrupter unit coordinates firing circuits to prevent ammunition collisions between intersecting weapon corridors.

Firearm receiver assembly with ambidextrous magazine, bolt, safety, and charging handle controls prevents inadvertent activation during combat operations.

Interchangeable lever members resolve skin snagging and pain by allowing users to select optimal dimensions for their specific anatomy.

Segmentation and intermediary keyhole design resolve the contradiction between secure storage and emergency access time.

An electronic controller and actuator replace mechanical linkages to reduce device complexity while maintaining versatile firing mode selection.
