Solution Overview

Problem

Existing rifle scope mounting systems on hunting and sporting weapons are not adequately secured against recoil, leading to distortion and loss of precision, resulting in unintended hit deviations and potential tilting of the rifle scope during firing.

Innovation Solution

The introduction of a weapon-side mounting base rail with upward-facing support surfaces and a recoil stud that engages in a transverse groove on the mounting body, combined with a spring plate that centers via index balls, provides a play-free transfer of recoil forces and secures the mounting body against tilting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a clamping lever with non-rotatable connection to clamping wings is used to attach the mounting body to the base rail, then the mounting body can be detachably connected to the base rail, but the connection is not suitable for weapon recoil and allows unintentional tilting play

Engineering Contradiction:
Improvedetachable connectionVSAvoidrecoil resistance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The mounting system is divided into separate functional elements: the base rail remains fixed to the weapon, while the mounting body can be detached. The recoil stud and groove provide a dedicated recoil management subsystem that is mechanically separated from the clamping mechanism, allowing each component to optimize its specific function without compromise.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The recoil stud acts as an intermediary element between the mounting body and base rail, specifically designed to manage recoil forces. This intermediary component transfers recoil loads through a dedicated path (stud to groove engagement) that is independent of the clamping lever mechanism, preventing recoil from affecting the optical alignment while maintaining easy detachability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a three-point support principle with semicircular fastening heads is used for positioning, then the mounting body can be positioned on the base rail, but the connection allows tilting play in the longitudinal axis

Engineering Contradiction:
ImprovepositioningVSAvoidalignment precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The traditional three-point support mechanism is replaced with a groove-and-stud engagement system. The transverse groove and recoil stud create a mechanical constraint that eliminates tilting play by providing a positive engagement geometry that prevents rotational movement around the longitudinal axis, while still allowing for straightforward positioning and attachment.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If the mounting body is secured to the rifle scope with fastening elements, then the rifle scope can be mounted, but the entire arrangement is not secured against being lifted off the weapon

Engineering Contradiction:
Improvemounting capabilityVSAvoidanti-lift security
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The anti-lift security is achieved by adding a vertical dimension constraint through the recoil stud engaging in the transverse groove. This vertical engagement prevents upward movement (lifting off) that cannot be prevented by horizontal clamping alone, creating a three-dimensional constraint system that secures the mounting body against all方向的 forces including recoil, lift, and tilt.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
