Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing weapon accessory mounts are incompatible with different types of weapon rails, such as Picatinny and Weaver rails, due to their distinct slot configurations, leading to issues with securing accessories and preventing longitudinal movement.

Innovation Solution

A weapon accessory mount assembly featuring a rail mount with a rail channel that can accommodate both Picatinny and Weaver rails, along with a rail slot key that has interchangeable key portions to fit different slot dimensions, ensuring secure mounting and preventing movement along the rail.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single key design is used for mounting accessories, then the device complexity is reduced, but the adaptability to different rail types (Picatinny and Weaver) deteriorates

Engineering Contradiction:

Improvemount structureVSAvoidcompatibility with different rail types

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The key is divided into multiple key portions (first key portion and second key portion), each with different dimensions configured for specific rail types. This segmentation allows a single key structure to accommodate multiple rail configurations without requiring entirely separate keys for each rail type.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The key is designed as a universal component that can function with both Picatinny and Weaver rails through its multiple key portions. By integrating different key configurations into one key, the mounting structure achieves multi-functionality, eliminating the need for separate keys for different rail types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If different key designs are used for different rail types, then the adaptability to different rail types is improved, but the device complexity increases

Engineering Contradiction:

Improvecompatibility with different rail typesVSAvoidmount structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple key designs for different rail types are merged into a single key structure. The first key portion and second key portion are combined in one key, allowing the user to select the appropriate portion for the specific rail type, thereby reducing the total number of separate components needed.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The key serves as a universal mounting component that can interface with both Picatinny and Weaver rails. By making the key multi-functional with its different key portions, the system reduces complexity compared to having entirely separate keys for each rail type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of manufacture

If a fixed key configuration is used, then the manufacturing precision is simplified, but the adaptability to different slot dimensions deteriorates

Engineering Contradiction:

Improvekey configurationVSAvoidcompatibility with different slot dimensions

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The key configuration is segmented into multiple key portions with different dimensions, each optimized for specific slot types. This allows the manufacturing process to produce a single key with varied geometries rather than requiring entirely separate manufacturing processes for different key types.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the key have different local geometries and dimensions tailored to specific rail slot types. The first key portion has dimensions suited for Picatinny slots while the second key portion has dimensions for Weaver slots, allowing each local region of the key to be optimized for its specific function.

Inventive Principle:

Principle #3Local quality

4Adaptability or versatility

If the key is made removable and reconfigurable, then the adaptability to different rail types is improved, but the reliability of the mounting connection may deteriorate

Engineering Contradiction:

Improvecompatibility with different rail typesVSAvoidmounting connection

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The appropriate key portion is selected and positioned in advance before mounting. The user configures the key with the correct key portion for the specific rail type beforehand, ensuring proper alignment and fit before insertion into the rail slot, which maintains connection reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The key acts as an intermediary component that bridges the accessory and the rail. By selecting the appropriate key portion as a mediator for the specific rail type, the connection maintains reliability while still allowing adaptability across different rail configurations.

Inventive Principle:

Principle #24Intermediary (Mediator)
