Trigger Guard Sheath with Nested Holster Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm trigger guards do not adequately prevent accidental discharge when a pistol is carried in a holster, as they may not securely encase the trigger and barrel, potentially allowing unwanted contact.
Innovation Solution
A trigger guard sheath with a molded plastic or KYDEX material design that forms an integral body with a top section for the barrel and a bottom section for the trigger, featuring protrusions for secure fitting within a holster, ensuring the trigger and barrel are fully enclosed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional trigger guard is used, then the structure is simple, but it does not adequately prevent accidental discharge when carried in a holster
Solution Approach 1:
The trigger guard sheath is disposed within the holster, creating a nested configuration where the sheath is inserted into the holster's trigger guard receiving portion. This nested structure provides enhanced trigger protection while maintaining a compact overall design that integrates seamlessly with the existing holster system.
Solution Approach 2:
The trigger guard sheath is divided into distinct functional sections: a top section with a first width configured to receive the barrel or slide, and a bottom section with a second width configured to receive the trigger and trigger guard. This segmentation allows each section to be optimized for its specific protective function while maintaining structural integrity.
2Reliability
If a snug fit is achieved for safety, then accidental discharge is prevented, but the fit may be too tight for easy insertion
Solution Approach 1:
The sheath features localized tapered portions at specific insertion points that create a friction-fit mechanism. These tapered sections allow the sheath to be easily inserted into the holster while maintaining a snug, secure fit once positioned, providing local flexibility to resolve the contradiction between secure retention and ease of insertion.
Solution Approach 2:
The friction-fit mechanism allows the sheath to transition from a loose state during insertion to a secure, snug fit once positioned. This dynamic adjustment enables easy insertion followed by reliable retention, with the fit adapting to the insertion process rather than maintaining a constant tightness level.

AI summary
A trigger guard sheath for a pistol and is configured to be disposed within a holster. The sheath includes an integral body that includes a top section having a first width and configured to receive a barrel or slide of the pistol and a bottom section having a second width and configured to receive a trigger and trigger guard of the pistol. The integral body includes a first protrusion that extends radially outward from a first end of the top section and a first protrusion that extends radially outward from a first end and an inner wall of the top section in a first direction and a second protrusion that extends radially outward from a second end and outer wall of the bottom section in a second direction that is opposite the first direction.
