Firearm Optic Mounting Assembly for Repositionable Sight Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm optic assemblies face challenges in removably attaching multiple accessories to user-selectable locations due to issues like permanent wedging of components, limiting flexibility and redundancy in sight configurations.
Innovation Solution
A firearm optic assembly with a body featuring a first mounting facility for a Picatinny rail connection and a second mounting facility with slidably received protrusions in pockets, allowing easy repositioning and secure attachment of accessories like telescopic and red dot sights, with alignment flares for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a protrusion with taper and anodized aluminum coating is used in the mounting facility, then the attachment strength is improved, but the protrusion becomes permanently wedged in the pocket and cannot be removed or repositioned
Solution Approach 1:
The patent changes the geometric parameters of the protrusion by eliminating the taper and modifying the coating properties. The protrusion is made substantially tapered-free with a flat or slightly rounded end, and the anodized aluminum coating is replaced or modified to reduce friction and prevent permanent wedging, while maintaining adequate attachment strength through controlled interference fit.
Solution Approach 2:
The mounting facility transitions from a static, permanent attachment system to a dynamic, reversible system. The protrusion is designed to be insertable and removable from the pocket, allowing users to reposition accessories between different mounting locations. The interference fit is controlled to provide sufficient holding strength during use while allowing easy removal when needed.
2Adaptability or versatility
If multiple mounting locations are provided for accessories, then the adaptability and versatility are improved, but the device complexity increases
Solution Approach 1:
The mounting facility is segmented into multiple discrete pockets distributed at different locations and angles on the optic assembly body. Each pocket is an independent, identical structural unit that can receive a standardized protrusion. This segmentation allows accessories to be mounted at multiple user-selectable locations without requiring complex unique interfaces for each position.
Solution Approach 2:
The patent implements a universal mounting interface where all pockets share the same dimensions, orientation, and reception characteristics. A single protrusion design can be inserted into any pocket, and the same removal and reinsertion procedure applies to all locations. This universal interface simplifies the overall structure while enabling versatile accessory placement options.
