Modular Holster Retention Assembly with Interlocking Wedges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gun holsters are prone to accidental discharge or unauthorized removal, posing a risk to users, especially in situations where criminals may attempt to snatch the firearm or children may access it.
Innovation Solution
A modular firearm holster safety retention assembly featuring a saddle with a pivot release arm and interlocking wedges that securely lock the firearm in place, using a locking nub to engage the ejection port and a braking mechanism to prevent forceful removal, while accommodating various firearm sizes and types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional holster with a buckle strap is used to enclose the gun, then the gun can be secured in the holster, but the holster is prone to accidental discharge or unauthorized removal by criminals or children
Solution Approach 1:
The retention system is divided into separate functional components: a saddle that receives the barrel, a pivot release arm with locking nub, and interlocking wedges. This segmentation allows each component to perform its specific function independently, creating a more reliable multi-stage retention system that prevents unauthorized extraction while requiring a deliberate release action.
Solution Approach 2:
The locking nub is positioned to automatically engage with the ejection port when the firearm is inserted into the saddle, providing preliminary locking action before the user can remove the firearm. The interlocking wedges are pre-configured to engage with the saddle, creating a braking mechanism that must be overcome before extraction is possible.
2Reliability
If a secure locking mechanism is implemented to prevent unauthorized removal, then firearm security is improved, but the device complexity increases with multiple components like pivot release arm, locking nub, and interlocking wedges
Solution Approach 1:
The pivot release arm is designed to be manually actuated by the user to release the locking nub from the ejection port. The system serves itself by using the user's own action to both secure and release the firearm, eliminating the need for separate locking and unlocking mechanisms operated by different components.
Solution Approach 2:
The pivot release arm transitions from a static blocking position (when engaged) to a dynamic movable position (when pivoted). This dynamic capability allows the same component to provide both security during transport and easy release during authorized use, reducing the need for additional static locking components.
3Reliability
If the holster is designed to fit specific firearm types and sizes, then the retention security is improved through proper fit, but the adaptability to accommodate different types and sizes of firearms is reduced
Solution Approach 1:
The saddle is designed with a universal geometry that can receive and secure multiple types and sizes of firearms through its barrel-receiving structure. The interlocking wedges and pivot release arm mechanism provide a standardized retention system that adapts to different firearm dimensions while maintaining secure retention through the same fundamental locking principle.

AI summary
A modular firearm holster safety retention assembly is operable with a holster to prevent unauthorized extraction or accidental drop of a firearm from holster. The assembly comprises a saddle that receives the barrel of a firearm, and a pivot release arm that couples to the saddle to selectively restrict movement or release the firearm in the holster. The pivot release arm detachably couples to the saddle. The pivot release arm has a first end with a protruding locking nub that engages the ejection port of firearm to restrict movement thereof; and a second end that is urged away from the saddle to disengage the locking nub from the firearm ejection port to disengage firearm from saddle. The saddle and the pivot release arm have interlocking wedges that restrict forceful removal of the firearm from holster. The saddle has a pivot stop to prevent overleveraging of pivot release arm.
