Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing mounts for weapon accessories fail to maintain stability and accurate positioning under recoil forces and do not allow for easy alignment of optical axes between different types of accessories on various weapons.

Innovation Solution

A mount with a base plate featuring aligned grooves and protrusions that securely engage with a rail and accessory, preventing displacement and recoil, and allowing for adjustable alignment using spacer plates for different weapon types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing mounts are used to attach accessories to weapons, then accessories can be mounted on weapons, but play occurs between the accessory and the weapon causing instability and inaccurate positioning under recoil forces

Engineering Contradiction:

Improvestability and accurate positioningVSAvoidmount design complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The base plate is segmented into multiple engagement features including first protrusions that engage with first grooves for longitudinal positioning, and a second protrusion that engages with a second groove for transverse positioning. This segmentation of engagement features eliminates play between the accessory and weapon while maintaining a relatively simple overall mount structure.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If accessories are mounted on weapons of different types and at different levels, then versatility is improved, but alignment of optical axes between accessories becomes difficult

Engineering Contradiction:

Improvecompatibility with different weapons and accessoriesVSAvoidoptical axis alignment precision

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The base plate is designed as a universal mounting interface that can accommodate accessories of different kinds on weapons of different types. The standardized groove and protrusion configuration allows the same base plate design to be used across various weapon platforms while maintaining proper optical axis alignment through the consistent engagement geometry.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A mount for mounting an accessory (19) on a weapon comprises a base plate (12) with an upper surface and a lower surface, to be connected with the accessory. The base plate (12) is clamped to a rail (10) on the weapon with the lower surface engaging the rail. Two aligned first grooves (23) in the upper surface extend in the longitudinal direction of the rail and a third groove (24) in the upper surface of the base plate, extends transversely of the first grooves. First protrusions (25) on the lower surface of the accessory guidingly engage the first grooves, and a third protrusion (26) on the lower surface of the accessory located between the first protrusions engages the third groove (24) to prevent displacement of the accessory along the first grooves.
