Firearm Safety Selector Assembly Slide-Mounted Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
New firearm users are apprehensive about guns lacking a positively moving safety switch, particularly striker fire guns that integrate safety features differently, leading to concerns about carrying or storing these weapons.
Innovation Solution
A safety selector assembly for firearms, comprising a safety selector switch, actuator, stem, safety selector shaft with a cam surface, and an interference piston, which can be positioned on the slide to provide a movable safety switch, allowing users to easily determine if the gun is in a fire-ready or safe position, thereby addressing user concerns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a safety switch is integrated into the trigger or frame, then the firearm has a safety feature, but new users remain apprehensive due to lack of a positively moving safety switch
Solution Approach 1:
The safety mechanism is segmented into separate functional components: a safety selector switch for user operation, a safety plunger for mechanical actuation, and an interference piston for positioning control. This segmentation allows each component to perform its specific function independently, providing a clear and positive safety indication while maintaining reliability.
Solution Approach 2:
The interference piston acts as an intermediary mechanism between the safety selector switch and the safety plunger. It translates the user's switch operation into the appropriate mechanical action on the safety plunger, providing a positive and reliable safety feature while maintaining ease of operation through clear mechanical feedback.
2Ease of operation
If a safety selector switch is added to the slide, then user confidence is improved, but the device complexity increases
Solution Approach 1:
The safety selector assembly merges multiple functions into a single integrated unit mounted on the slide: the safety selector switch for user input, the safety plunger for mechanical safety actuation, and the interference piston for positioning. This consolidation provides enhanced user confidence while minimizing the increase in overall device complexity by combining rather than adding separate systems.
3Ease of operation
If the safety selector switch is positioned on the slide, then it becomes easily locatable, but the manufacturing precision requirements increase
Solution Approach 1:
The safety selector assembly is pre-assembled as a complete unit with all components (switch, plunger, interference piston) properly positioned and aligned before mounting to the slide. This preliminary assembly ensures that the accessibility and positioning requirements are met during manufacturing, as the entire assembly is installed as one unit rather than requiring precise individual component placement.
