Weapon Assembly/Disassembly TRIZ Cases
- Pivot Pin Aperture Design for Controlled Detent Installation
An aperture through the pivot pin lets a common tool guide and retain the detent, reducing expulsion risk and installation force.
- Rifle Receiver Slit Expansion for Contaminant-Tolerant Barrel Assembly
A rotatable bolt and abutment widen the receiver slit so the barrel can be reassembled quickly despite minor contamination.
- Locking Takedown Pin With Internal Release for Receiver Reassembly
A nested release pin and spring-loaded detent simplify secure firearm receiver detachment and reliable reassembly.
