Solution Overview

Problem

Existing adapter devices for attaching optical attachments like night vision or thermal imaging devices to rifle scopes often fail to achieve precise and repeatable alignment of optical axes, leading to potential offset during firing, which affects aiming accuracy, especially in limited lighting conditions.

Innovation Solution

A clamping ring adapter device with a holding contour for releasable positive or non-positive attachment to the rifle scope, featuring a retaining ring with adjustable locking elements and interrupted round threads for precise alignment, allowing for non-destructive and repeatable attachment without requiring zeroing adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a clamping ring adapter device is used to attach an optical attachment to a riflescope, then the attachment can be securely fixed to withstand recoil forces, but achieving precise and repeatable alignment of optical axes becomes difficult

Engineering Contradiction:
Improvefixation strengthVSAvoidoptical axis alignment precision
Core Design Contradiction:
StrengthVSMeasurement precision

Solution Approach 1:

The adapter device serves as an intermediary component between the clamping ring and the optical attachment. It includes a clamping ring portion that secures to the riflescope and an attachment adapter portion that interfaces with the optical attachment. This mediator enables both strong mechanical fixation and precise optical axis alignment by providing separate functional zones for each requirement.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The adapter device is divided into distinct segments: a clamping ring portion for mechanical attachment and an attachment adapter portion for optical alignment. This segmentation allows each part to be optimized independently - the clamping ring for strength and the adapter portion for precision alignment - thereby resolving the contradiction between fixation strength and alignment precision.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If the attachment is positioned as flush as possible with the riflescope to align optical axes, then aiming accuracy improves, but the attachment becomes vulnerable to recoil stress

Engineering Contradiction:
Improveaiming accuracyVSAvoidrecoil resistance
Core Design Contradiction:
Measurement precisionVSStrength

Solution Approach 1:

The adapter device acts as a buffer zone between the riflescope and the optical attachment. It allows the attachment to be positioned optimally for optical alignment while absorbing and distributing recoil forces through its clamping mechanism, preventing direct transmission of stress to the attachment's optical components.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Strength

If a mounting rail is used to attach the attachment to the firearm, then the attachment can be securely mounted, but precise alignment with the riflescope's optical axis is difficult to achieve

Engineering Contradiction:
Improvemounting securityVSAvoidoptical axis alignment
Core Design Contradiction:
StrengthVSMeasurement precision

Solution Approach 1:

The solution separates the mounting function from the alignment function. The clamping ring portion provides secure mounting to the riflescope, while the attachment adapter portion provides precise optical axis alignment. This segmentation allows each function to be optimized independently, overcoming the limitations of using a single mounting rail for both purposes.

Inventive Principle:
Principle #1Segmentation
