Safety Arrangement TRIZ Cases
- Event Detection Using Inertial and Signal Feature Matching
Combining inertial data with one component signal detects object events without separate sensors on the trigger, slide, and magazine.
- Lower Receiver Ejector Arm for Consistent Firearm Ejection
Integrating an ejector arm into the lower receiver improves cartridge case ejection consistency while reducing separate part alignment issues.
- Interchangeable Firearm Bottom Metal for Universal Stock Fit
A universal stock opening and interchangeable bottom metal assembly let one firearm stock fit DBM or hinged floor plate setups across cartridge lengths.
- Sighting Human Detection to Trigger Abnormal Aiming Warnings
Deep learning human recognition in a sighting view triggers abnormal aiming mode to prevent accidental shooting at people.
- Ambidextrous Bolt Catch Release Using a Spring-Biased Cam Plunger
A spring-biased side plunger wedges against a cam ramp to release the bolt catch from either side while avoiding added friction and inertial load.
- Electromechanical Sear Assembly for Fast Low-Wear Firing Control
A coil-triggered actuator moves the sear quickly between safe and firing states, cutting wear, transition force, and mechanical failure risk.
- Firearm Magazine Locking Retainer for Reduced Spring Wear
A retainer separates the magazine from the locking spring, preserving secure fixation while reducing spring wear and simplifying maintenance.
- Forcing-Cone Deformation Sensing for Projectile Positioning
Strain gauges measure deformation at a weapon barrel’s forcing cone against a threshold, verifying projectile positioning and flagging detachment risk.
- Smart Firearm Safety Lock with Motion Detection
Motion sensing detects firearm orientation or movement, enabling radio-controlled trigger locking through a property monitoring system.
