Solution Overview

Problem

Existing dual-sight mounts for firearms are heavy, noisy, and affect accuracy and precision due to their articulated mechanisms, with cumbersome designs that complicate quick transitions between optical components.

Innovation Solution

A pivotably connected sight and accessory mount for firearms, where the accessory mount protrudes from the sight mount in a direction aligned with the firearm, allowing for a low-weight, silent operation with minimal impact on accuracy, featuring a monolithic structure and optimized cuts for reduced weight and footprint.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an articulated mechanism is used in a selectable dual-sight mount, then one optical component can shift in position relative to the firearm, but the weight increases significantly

Engineering Contradiction:
Improveselectability of optical componentsVSAvoidweight of sight mount
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The accessory mount is designed to be pivotably connected to the sight mount, allowing it to dynamically shift between a first position (aligned with the sight) and a second position (pivoted away). This dynamic configuration enables selective use of different optical components without requiring a fixed dual-sight structure, reducing overall weight while maintaining versatility.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If an articulated mechanism is used in a selectable dual-sight mount, then one optical component can shift in position, but noise is generated that may reveal the operator

Engineering Contradiction:
Improveselectability of optical componentsVSAvoidnoise from articulated mechanism
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The pivotable connection allows the accessory mount to be dynamically positioned. When in the second position (pivoted away), the accessory mount and its optical component are displaced from the direct sightline, enabling silent operation without requiring the noisy articulated mechanism to be actively engaged during shooting.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If an articulated mechanism is used in a selectable dual-sight mount, then one optical component can shift in position, but play is caused that decreases accuracy and precision

Engineering Contradiction:
Improveselectability of optical componentsVSAvoidshooting accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The pivotable connection provides controlled movement between defined positions. When the accessory mount is in the first position, it aligns with the sight for accurate aiming. The dynamic design allows precise positioning without the unwanted play that would occur with traditional articulated mechanisms.

Inventive Principle:
Principle #15Dynamics

4Reliability

If a fixed dual-sight mount is used, then no articulation is present, but tooling is required to remove optical components

Engineering Contradiction:
Improvestability of mountVSAvoidremoval of optical components
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The sight mount is segmented into a fixed sight mount portion and a separately pivotable accessory mount portion. This segmentation allows the accessory mount to be independently positioned and removed without affecting the fixed sight mount, providing both stability and ease of operation.

Inventive Principle:
Principle #1Segmentation

5Adaptability or versatility

If a traditional sight and accessory mount is used, then both sight and accessory can be mounted, but the footprint on the firearm is large

Engineering Contradiction:
Improvemounting of sight and accessoryVSAvoidfootprint on firearm
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The accessory mount pivots on an axis that allows it to be positioned in line with the sight when needed. This dynamic arrangement eliminates the need for separate mounting spaces, reducing the overall footprint on the firearm while maintaining the ability to mount both sight and accessory.

Inventive Principle:
Principle #15Dynamics

AI summary

A sight mount for a firearm having a rail, wherein the sight mount comprises: - a first sight mount arranged to carry, or fasten, a sight, - a second sight mount arranged to carry, or fasten, a accessory, wherein the second sight mount is pivotably connected to the first sight mount and arranged to carry, or fasten, a accessory, and the second sight mount protrudes from the first sight mount in a rearward, or forward, direction relative to the firearm, and wherein the second sight mount has a first end position and a second end position relative to the first sight mount between which it can pivot, wherein in the first end position the accessory is aligned with the sight, and in the second end position the accessory is pivoted away from the sight.
