Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional scope mounting systems for firearms often fail to accommodate non-round barrel profiles, require permanent modifications, and lack stability, leading to damage and misalignment issues.

Innovation Solution

A clamping mechanism with L-shaped clamp members that engage multiple planar surfaces of the barrel, using fasteners for secure attachment, and optionally includes protective films to prevent marring, allowing quick release without tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional mounting systems are used, then attachment is achieved, but compatibility with non-round barrel profiles is poor

Engineering Contradiction:

Improvecompatibility with different barrel geometriesVSAvoidstability of attachment

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The clamp member is divided into multiple engagement surfaces (first planar surface, second planar surface, third planar surface) that can independently contact different portions of the barrel. This segmentation allows the mounting system to adapt to various barrel geometries including non-round profiles while maintaining stable attachment through distributed contact points.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The clamp member is designed with multiple planar surfaces that can engage with different barrel profiles (round, square, oval, faceted). This multi-functional design enables a single mounting system to universally accommodate various firearm barrel geometries without requiring geometry-specific adapters or modifications.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If permanent modifications are made to the barrel, then secure attachment is achieved, but structural integrity and collector value are compromised

Engineering Contradiction:

Improvesecurity of attachmentVSAvoiddamage to firearm surface

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The clamp member acts as an intermediary between the accessory and the barrel, providing mechanical attachment without direct fastening to the barrel. The multiple planar surfaces of the clamp member distribute clamping forces across several contact points on the barrel, achieving secure attachment while preventing localized damage, scratches, or deformation of the firearm surface.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The clamp member functions as a flexible mounting shell that can conform to different barrel profiles through its multiple planar surfaces. This flexible adaptation allows secure attachment without rigid fastening methods that would require permanent modifications or cause surface damage to the barrel.

Inventive Principle:

Principle #30Flexible shells and thin films

3Ease of operation

If clamping rings are used, then attachment is achieved, but stability under recoil and vibration is insufficient

Engineering Contradiction:

Improveease of attachmentVSAvoidresistance to slippage or rotation

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

Different surfaces of the clamp member have optimized local qualities for specific functions: the first and second planar surfaces provide stable engagement with the barrel, while the third planar surface is configured to engage with the accessory. This localized optimization of surface geometries ensures resistance to slippage and rotation under recoil and vibration while maintaining ease of attachment.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The mounting system transitions from simple circumferential clamping to multi-dimensional engagement using three distinct planar surfaces oriented at different angles. This dimensional expansion creates a more stable attachment that resists slippage and rotation in multiple directions while maintaining operational simplicity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Ease of manufacture

If inadequate surface conformity is used, then attachment is achieved, but uneven clamping forces cause slippage or surface damage

Engineering Contradiction:

Improvesimplicity of mounting systemVSAvoiduniformity of clamping forces

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The clamp member incorporates multiple planar surfaces that can conform to both curved and angular barrel profiles. This geometric design allows the mounting system to achieve uniform surface contact and even force distribution across the barrel surface, preventing slippage and localized damage while maintaining manufacturing simplicity.

Inventive Principle:

Principle #14Spheroidality (Curvature)

AI summary

A clamping mechanism for mounting an accessory, such as a scope, to a firearm barrel includes first and second clamp members with inner planar surfaces configured to engage respective outer surfaces of the barrel so as to distribute clamping forces evenly and minimizing damage to the barrel surface. A dovetail section on one of the clamp members enables attachment of various optics or accessories. The clamp members are secured together using one or more fasteners passing through aligned openings in the clamp members. The clamping mechanism allows non-permanent, stable mounting of accessories without requiring permanent modification to the firearm. The clamping mechanism is particularly configured to be mounted on the barrel of a Henry® brand rifle.
