Integrated Trigger Locking Pin for Firearm Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trigger locking mechanisms can cause user discomfort and interference during voluntary trigger pressing due to their design, which can lead to involuntary firing prevention issues.
Innovation Solution
The trigger locking pin is designed with specific angles and positions, such as a 3-degree angle with the h axis and an 18-degree angle with the sharp tip, ensuring it remains integrated with the trigger, preventing separation and allowing smooth voluntary operation while maintaining involuntary firing prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate safety member is placed between two trigger parts to prevent involuntary firing, then firing safety is improved, but the user experiences disturbance and discomfort during voluntary trigger pressing
Solution Approach 1:
The patent merges the trigger locking pin with the trigger body into a single integrated component. The locking pin is formed as an integral part of the trigger, eliminating the need for a separate safety member between trigger halves. This integration maintains the locking function while eliminating the physical obstruction that caused user discomfort during voluntary pressing.
Solution Approach 2:
The invention extracts the safety function from a separate component and integrates it directly into the trigger structure. By incorporating the locking pin as part of the trigger itself rather than as a separate safety member, the design removes the interfering element while preserving the involuntary firing prevention capability.
2Reliability
If the trigger locking pin is positioned to effectively block involuntary trigger movement, then safety against accidental firing is improved, but the trigger mechanism becomes more complex
Solution Approach 1:
The trigger locking pin is combined with the trigger body as a single integrated component rather than separate parts. This merging reduces the overall number of components in the trigger assembly while maintaining the locking function, thereby simplifying the device structure rather than complicating it.
Solution Approach 2:
The integrated trigger locking pin performs multiple functions: it acts as both the trigger structure and the safety locking mechanism. This multi-functionality eliminates the need for additional dedicated safety components, reducing device complexity while maintaining reliable accidental firing prevention.
