Solution Overview

Problem

Existing mounting devices for target devices on handguns often result in friction-related wear and inconsistent clamping, making them prone to repeatable and precise mounting issues.

Innovation Solution

A device with a rotatable holding element that decouples from the actuating element during clamping, allowing for precise and low-wear engagement by limiting rotation and using a latching connection to define locking and release positions, ensuring the holding element does not rotate during clamping, thus reducing abrasion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If the clamping jaw is rotated during clamping, then the clamping force is applied, but friction-related wear and signs of use occur on the handgun surface

Engineering Contradiction:

Improveclamping forceVSAvoidfriction-related wear

Core Design Contradiction:

ForceVSObject-affected harmful factors

Solution Approach 1:

The holding element is designed to transition from a rotatable state during insertion to a locked non-rotatable state during clamping. This dynamic change allows the system to achieve both easy installation (rotation during insertion) and wear-free clamping (no rotation during force application), resolving the contradiction between applying clamping force and preventing friction wear.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The actuating mechanism is segmented into distinct functional phases: insertion phase with rotation, locking phase where rotation is limited, and clamping phase where only linear displacement occurs. This segmentation separates the rotational motion (for insertion) from the linear clamping motion, ensuring that rotation does not occur during the clamping phase, thus preventing wear on the handgun surface.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If the holding element is rotatable, then insertion is facilitated, but rotation during clamping causes wear on contact points

Engineering Contradiction:

Improveinsertion easeVSAvoidmounting consistency

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The holding element transitions from a rotatable state during insertion to a locked non-rotatable state during clamping. This dynamic change allows the system to achieve both easy installation (rotation during insertion) and wear-free clamping (no rotation during force application), resolving the contradiction between applying clamping force and preventing friction wear.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The locking mechanism is designed to limit rotation before the clamping phase begins. By preliminarily locking the holding element at a specific rotation angle, the system ensures that subsequent clamping movements produce only linear displacement without rotation, thereby preventing wear and ensuring consistent mounting results.

Inventive Principle:

Principle #10Preliminary action

3Manufacturing precision

If the clamping jaw moves along the handgun surface, then engagement is achieved, but abrasion occurs on sensitive surfaces

Engineering Contradiction:

Improveengagement precisionVSAvoidabrasion on sensitive surfaces

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The locking mechanism acts as an intermediary that decouples the rotational motion from the clamping motion. By introducing this intermediate locking stage, the system ensures that rotation is completed before contact with the handgun surface, and subsequent movements are purely linear, thus preventing abrasion on sensitive surfaces while maintaining engagement precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The invention relates to a device for mounting a sighting device on a handgun, comprising a bracket (2) which includes at least one fixed holding element and an opposing holding element (5) rotatable relative to the bracket (2) about a pivot axis (20), the latter being adjustable relative to the fixed holding element (3) by means of an actuating element (19). To enable repeatable and low-wear mounting, the actuating element (19) is rotatable relative to the rotatable holding element (5) about its pivot axis (20).
