Safety Arrangement TRIZ Cases
- Ambidextrous Bolt Catch Mechanism for Controlled Jam Clearing
A secondary actuator lets either hand operate the bolt catch, supporting rapid jam clearing while maintaining firearm control.
- Ammunition Magazine Follower Ramps Preventing Cartridge Misfeeds
This case uses angled, curved follower ramps to guide cartridges without bullet contact, reducing misfeeds during rapid feeding.
- Locking Magazine Rotor Mechanism for Accidental Discharge Prevention
A user-selectable rotor and block element lock the magazine, preventing firing and extraction while preserving ammunition capacity.
- Electromechanical Gun Biometric Templates for Privacy-Safe Authentication
A random projection preserves biometric similarity for gun unlocking while keeping original biometric data out of memory.
- Spring-Loaded Button Detent Retention for Magazine Catch Alignment
A threaded rod, spring, and mating detent surfaces prevent over-depression and loosening during magazine catch button installation.
- Rail-Mounted Firearm Trigger Lock with Proximity Relocking
A spring-loaded slide and electromechanical lock relock the firearm trigger when the authorized wrist device leaves range.
- Non-Lethal Gas Gun Magazine for Automatic Feeding and Gas Regulation
This case combines automatic projectile feeding with a pressure-regulated gas magazine to reduce reloading time and mechanical wear.
- Auto-Loading Firearm Trigger Assembly for Safe Training Mode
A mechanical selector separates live-fire and training pathways, preserving trigger reset and realistic feedback without discharge.
- Takedown Lever Safety Block for Handgun Trigger and Magazine Lockout
The takedown lever uses a safety block to block trigger rotation and magazine insertion, reducing discharge risks during cleaning.
- Trigger Shoe Assembly with Magazine-Well Set Screw Adjustment
Angled surfaces, lips, and a vertical set screw enable precise trigger shoe engagement adjustment without full firearm disassembly.
- Pistol Trigger Assembly With Spring-Biased Blocked Position
A pivoting trigger shoe and spring use the pistol frame to block movement, balancing firing control with deliberate actuation.
- Ambidextrous Bolt and Magazine Release Integration for Pistol Magazines
A sliding magazine release and paired bolt actuators improve ergonomic reloading from either side while supporting pistol-style magazines.
- Firearm Trigger Sear Link Design for Smooth Pull and Setting Stability
This case shows how a sear link and detent screws tailor trigger pull while stabilizing settings against shock or misalignment.
- Caliber-Selective Magazine Latch Preventing Incorrect Insertion
This case uses asymmetric latch geometry to distinguish cartridge calibers while retaining magazine compatibility across weapon platforms.
- CEW Magazine Locking and Self-Alignment for Electrode Delivery
Bias springs, datums, and graded ramps secure CEW magazines for consistent electrode alignment and stimulus delivery.
- Zero-Radio Firearm Discharge Monitoring With Automated Shot Counting
An accelerometer-based module detects discharge events, maintains shot counts, and selectively sends stored data to a server.
