Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holsters for law enforcement officers face challenges in securely retaining a handgun while ensuring easy and intuitive release in stressful situations, with a need for cost-effective and ergonomic design that minimizes parts and assembly steps.
Innovation Solution
A thumb-actuated polymer holster with a pivoting lever mechanism that includes a thumb button positioned for ergonomic release, featuring a U-shaped shroud and lever that pivot between retention and release positions, and a dual-layer polymer construction for enhanced security and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is added to securely retain the handgun in challenging situations, then retention security is improved, but device complexity increases
Solution Approach 1:
The patent combines the retention mechanism and release mechanism into a single integrated lever assembly. The lever includes a trigger guard block portion that directly interacts with the handgun trigger guard, and a thumb button portion that is actuated by the user's thumb. This merging eliminates the need for separate retention and release components, achieving secure retention while maintaining simplicity.
Solution Approach 2:
The lever serves multiple functions simultaneously: it blocks the trigger guard to prevent unauthorized access, provides a thumb actuated release mechanism, and guides the user's thumb through integrated thumb guides. This multi-functionality reduces the overall number of components needed in the holster system.
2Ease of operation
If a thumb button is made accessible for easy actuation, then ease of operation is improved, but unintended access by others increases
Solution Approach 1:
The patent implements thumb guides that are specifically positioned to guide only the user's thumb to the thumb button. These guides create a localized access path that accommodates the anatomical shape of a thumb while preventing other objects or fingers from reaching the button. The thumb guides essentially create a customized interface that is ergonomic for the intended user but inaccessible to others.
3Reliability
If multiple retention mechanisms are added to enhance security, then retention security is improved, but manufacturing cost increases
Solution Approach 1:
The patent integrates multiple retention functions into a single lever component. The lever includes a trigger guard block portion that provides active retention by blocking the trigger guard, and the lever's pivotal connection to the holster body provides passive retention through friction and geometric constraints. This integration eliminates the need for multiple separate retention mechanisms, reducing part count and assembly steps while maintaining security.
4Reliability
If a U-shaped shroud is added to obstruct withdrawal path, then retention security is improved, but device complexity increases
Solution Approach 1:
The patent integrates the shroud function into the lever assembly itself. The lever includes a thumb button portion that extends toward the user and a trigger guard block portion that engages the handgun. The lever's body acts as the shroud, obstructing the withdrawal path when in the retained position. This integration eliminates the need for a separate U-shaped shroud component.

AI summary
A holster for receiving and withdrawing a handgun has a proximal wall portion with a handgun retention mechanism thereon. The mechanism having a first lever with a tab portion for actuation and release of a trigger guard, the lever having a snap fit into a lever region without a separate pin. A belt engaging member covers the lever region capturing the first lever therein. If a second retention mechanism is used, another lever with a tab portion is positioned so the tabs are stacked, depressing one also depresses the tab behind it, such that both mechanisms are released. Overmolded polymer layers in the holster body provides a softer interior handgun engagement surfaces. The holster body is split forwardly with a threaded fastener for clamping onto the handgun. No holster body is beneath or rearward of the tab portion, configured as a thumb button, allowing smooth transition to gripping the handgun.
