Firearm Selector Lever with Visual Element Recess
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearms safety selector levers are difficult to visually determine in low light or darkness, lacking efficient illumination to identify their position.
Innovation Solution
The design incorporates a safety selector lever with a visual element recess and viewing apertures, allowing illumination through photoluminescent, phosphorescent, or fluorescent materials to make the selector position visible, featuring a securing screw for retention and secondary apertures for enhanced light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional safety selector lever design is used, then the structure remains simple and manufacturing is easy, but visual identification in low light or darkness becomes difficult
Solution Approach 1:
The visual element is nested within a recess in the selector lever, with viewing apertures providing access to the embedded visual indicator. This allows the illumination system to be integrated into the existing lever structure without adding external components.
Solution Approach 2:
The visual element is positioned in a specific recess area of the selector lever, providing localized illumination exactly where needed for position identification, rather than attempting to illuminate the entire lever assembly.
2Illumination intensity
If visual elements and viewing apertures are added to the selector lever, then visual identification in low light improves, but manufacturing complexity increases
Solution Approach 1:
The selector lever is divided into functional zones: the main lever body and a separate recess area for the visual element. This segmentation allows the visual indication system to be manufactured and assembled as a modular component, simplifying the overall manufacturing process.
Solution Approach 2:
The viewing apertures serve multiple functions: they allow visual observation of the safety selector position, provide structural definition for the recess area, and can be integrated into the existing lever manufacturing process without requiring separate assembly steps.
