Removable Magazine Trigger Unit for Rapid Small Arm Unloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Repeating rifles with a cylinder breech mechanism require high effort to completely unload the weapon, especially when the magazine is located above the trigger guard, making it difficult for rapid unloading and loading, especially in scenarios like transporting inside a vehicle or entering a building.
Innovation Solution
An insertion magazine with a trigger unit affixed to its underside, allowing the magazine and trigger unit to be removed and reattached quickly, featuring a blocking mechanism that locks the magazine in place using a compression spring, preventing accidental discharge due to icing or soiling, and allowing for easy adaptation to different calibers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the magazine is located above the trigger guard for compact construction, then the weapon structure is more compact, but the effort to completely unload the weapon increases significantly
Solution Approach 1:
The magazine system is segmented into two independent parts: the magazine itself and the trigger unit. By detaching the trigger unit from the receiver and attaching it to the magazine, the patent enables the magazine to be removed as a complete assembly, allowing rapid unloading without manual extraction of cartridges. This segmentation resolves the contradiction by maintaining compact above-trigger-guard placement while enabling easy removal through modular design.
Solution Approach 2:
The trigger unit is merged with the magazine to form a unified removable assembly. This combination allows the entire magazine-with-trigger unit to be extracted together from the weapon, transforming the unloading process from a complex multi-step operation into a single removal action. The merging enables rapid unloading while preserving the compact magazine placement above the trigger guard.
2Productivity
If the magazine is removed completely for rapid unloading, then unloading speed increases, but the risk of accidental discharge increases due to trigger exposure
Solution Approach 1:
The trigger unit remains permanently attached to the magazine assembly, creating a unified component that is removed and reinstalled as one unit. This merging ensures that the trigger is never exposed or detached independently, eliminating the risk of accidental discharge during magazine changes. The trigger-stay-attached-to-magazine configuration maintains safety while enabling rapid unloading through complete assembly removal.
Solution Approach 2:
The magazine assembly acts as an intermediary carrier for the trigger unit during removal and installation operations. By keeping the trigger unit attached to the magazine throughout the unloading process, the system uses the magazine as a protective intermediary that prevents direct exposure of the trigger mechanism, thereby maintaining reliability while enabling rapid unloading.
3Reliability
If a blocking mechanism is added to prevent accidental discharge, then safety improves, but the device complexity increases
Solution Approach 1:
The blocking mechanism is merged into the existing trigger unit-magazine assembly rather than being added as a separate component. The blocking element utilizes the natural interaction between the trigger unit and magazine housing, employing existing structural features to provide safety functionality. This integration approach improves reliability while minimizing additional complexity by reusing existing components and spatial relationships.
Solution Approach 2:
The blocking mechanism operates automatically through the natural insertion and removal motions of the magazine assembly. The blocking element engages and disengages passively as the magazine is inserted or removed, without requiring additional actuators, sensors, or control systems. This self-service operation maintains safety functionality while avoiding the complexity of active control mechanisms.

Function Achieved in This Case
Enables rapid and simple unloading and loading of the rifle with full magazine capacity, ensuring the weapon is ready for immediate use, even when the magazine is above the trigger guard, and prevents accidental shots by ensuring the trigger is only active when the magazine is fully locked.
Implementation Method 1
a blocking element, which is brought into a locking position by a compression spring
