Solution Overview
Problem
Existing rifle scope mounting devices on hunting or sporting weapons suffer from instability and lack of precision due to the narrow mounting area and inadequate clamping force distribution, leading to reduced shooting accuracy, especially under high recoil conditions.
Innovation Solution
A mounting device featuring a base rail attached to the weapon with a clamping screw that engages a stud bolt with a wedge recess, allowing for a new clamping principle that includes a horizontal clamping bolt, providing a force-fitting influence and ensuring precise, repeatable positioning of the rifle scope, with adjustable clamping force and limited rotational range to prevent loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a base rail is embedded in the breech box of the weapon, then the mounting width is reduced, but the mounting area becomes too small and the mounting rail is attached unstably
Solution Approach 1:
A base plate is introduced as an intermediary component between the weapon's breech box and the mounting rail. The base plate distributes the mounting area over a larger surface of the breech box, providing both increased mounting area and enhanced stability. This mediator resolves the contradiction by decoupling the mounting rail's stability requirement from the constrained space within the breech box.
2Ease of operation
If hemispherical alignment elements are used on the underside of the riflescope-side mounting device, then alignment is simplified, but the mounting device is partially lifted out of the receiving elements during recoil
Solution Approach 1:
The alignment and clamping functions are segmented into separate components: hemispherical alignment elements for initial positioning and clamping elements (clamping lever with clamping wings) for securing against recoil. This segmentation allows each component to specialize in its function - alignment elements provide ease of positioning while clamping elements provide reliable retention during recoil.
Solution Approach 2:
The mounting device uses a composite approach combining different geometric forms - hemispherical alignment elements work together with planar clamping surfaces and wedge-shaped clamping wings. This composite structure leverages the advantages of each geometry: the hemisphere provides self-alignment while the flat clamping surfaces provide stable contact during recoil.
3Device complexity
If a single clamping element is used, then the device complexity is reduced, but the clamping force acts only perpendicular to the base rail surface without additional displacement force
Solution Approach 1:
The clamping element merges two functional components into one integrated unit: a clamping lever that generates perpendicular clamping force through rotation, and wedge-shaped clamping wings that generate displacement force along the base rail surface. This merging maintains relative simplicity while achieving both perpendicular and parallel clamping forces for enhanced precision.
4Reliability
If two spaced-apart clamping bolts are used, then the clamping precision is improved, but the actuation effort is increased
Solution Approach 1:
Two clamping functions are merged into a single clamping lever that rotates about a pivot axis. The lever carries two clamping wings at its ends, allowing both clamping points to be actuated simultaneously through one rotational motion. This eliminates the need for separate actuation of two bolts while maintaining the precision benefits of distributed clamping points.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures reliable, wear-free, and repeatable transmission of recoil forces, maintaining high precision and accuracy even with high recoil, by providing a stable attachment and adjustable clamping force, thus enhancing the repeatability and longevity of the assembly.
Implementation Method 1
wedge surfaces are arranged, which engage undercuts in the base rail on the weapon side and are thus clamped to the base rail on the weapon side by rotating the clamping lever
Implementation Method 2
a threaded bushing is arranged in the mounting rail and the threaded pin of the swivel lever is screwed into the threaded bushing of the mounting rail. When you turn the clamping lever, the thread setting in the threaded bushing is also adjusted, so that the clamping force is increased.

AI summary
The mounting device (2) has mounting arrangement at the side of a firearm, where a mounting rail (4) is connectable by a clamping element. A clamping force, acting perpendicular to the surface of the two rails, is generated by actuating the clamping element. The clamping element generates a displacement force acting in the axial direction of the two rails by clamping between the firearm-sided base rail (3) and the positively held mounting rail. The clamping element is connected by a clamping screw (10) formed by a clamping bolt.
