Firing/Trigger Mechanisms TRIZ Cases
- Compressed Air Gun Loading Lever Mechanism
Segmenting the hammer head from the body reduces power required for loading while maintaining impact force.
- Firearm Trigger Group Reducing Pull Weight via Dual Biasing
A firearm trigger group uses a secondary biasing member to counteract the primary hammer spring, optimizing mechanical advantage for lighter pull weight.
- Captive Bolt Stunning Device with Magazine Strip
A captive bolt stunning device uses a magazine strip to hold explosive cartridges, eliminating manual reloading time and hazardous spent cartridge handling.
- U-Shaped Bracket Handgun for Cost-Effective Sheet Metal Production
Segmented stamped sheet metal parts in a U-shaped bracket handgun resolve design complexity while maintaining reliable automatic firing functionality.
- Auto Sear Pivot Mechanism for Continuous Fire Control
A pivotally mounted auto sear body with angular trip locations enables hammer reciprocation within firearm lower receivers.
- Firearm Recoil Inversion Assembly Reducing Muzzle Climb
A recoil inversion assembly redirects rearward bolt motion through a transfer arm and lever to compress the spring.
- Rolling Trigger Mechanism for Low-Force Firearm Operation
A rolling trigger mechanism replaces sliding sears with ball bearings to reduce friction and enable smooth operation.
- Trigger Actuator for Firearm with Remote Switch Control
An actuator mounted adjacent to a firearm trigger pulls the trigger via commands from a controller linked to a pressure-sensitive switch.
- Auto Sear Trip Link for Compact AR Firearms
A drop-in auto sear trip link resolves the inability of shortened bolt carriers to actuate the sear without modifying upper or lower receivers.
- Adjustable Trigger Firearm with Laser Shot Feedback
Laser shot indicators project onto targets to show placement accuracy, resolving information loss in quiet dry firing without airsoft noise.
- Perpendicular Magazine Rifle for Pistol Cartridge Feeding
A rifle platform uses a perpendicularly mounted magazine to feed pistol cartridges directly into the chamber.
- Magwell Adapter Sear Spring Attachment for Compact Firearm Design
A magwell adapter integrates a sear spring aperture to assist magazine insertion and maintain firearm operability.
- Bowstring Release Device With Cylindrical Bearing Jaws
Cylindrical bearings in jaw grooves restrain lateral displacement and allow pivotal motion, resolving stability issues caused by manufacturing tolerance errors.
