Quick-Release Bipod Adapter Plate for Arca and Picatinny Rails

Solution Overview

Problem

Existing bipod and tripod adapters for firearms and photographic equipment often require bulky and heavy designs to accommodate both Arca and Picatinny/Weaver rail interfaces, lacking a compact and efficient solution for interchangeable mounting.

Innovation Solution

A quick-release adapter with angled wings and a threaded rod mechanism that allows for secure clamping onto both Arca and Picatinny/Weaver rails, featuring a body with angled faces and dowels for stability, enabling easy attachment and detachment of mounts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a clamp is designed with two different channels at different levels and widths to accommodate both Arca and Picatinny/Weaver rails, then the adapter can interface with both rail types, but the clamp becomes bulky and heavy

Engineering Contradiction:

Improveinterface compatibilityVSAvoidclamp weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The clamp is divided into two separate channels (first channel for Arca rail, second channel for Picatinny/Weaver rail) that are positioned at the same level and have the same width. Each channel is independently configured to accommodate its respective rail type, allowing the clamp to interface with both rail types without requiring one channel to be larger or positioned differently than the other.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If a clamp is designed with two different channels at different levels and widths to accommodate both Arca and Picatinny/Weaver rails, then the adapter can interface with both rail types, but the clamp becomes bulky and heavy

Engineering Contradiction:

Improveinterface compatibilityVSAvoidclamp volume

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The clamp is divided into two separate channels (first channel for Arca rail, second channel for Picatinnym/Weaver rail) that are positioned at the same level and have the same width. Each channel is independently configured to accommodate its respective rail type, allowing the clamp to interface with both rail types without requiring one channel to be larger or positioned differently than the other.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The two channels are arranged side-by-side horizontally rather than stacked vertically at different levels. This horizontal arrangement at the same level optimizes the spatial configuration, reducing the overall volume of the clamp while maintaining the ability to accommodate both rail types.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If a clamp is designed with two different channels at different levels and widths to accommodate both Arca and Picatinnym/Weaver rails, then the adapter can interface with both rail types, but the clamp becomes bulky and heavy

Engineering Contradiction:

Improveinterface compatibilityVSAvoidclamp structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The clamp is divided into two separate channels (first channel for Arca rail, second channel for Picatinnym/Weaver rail) that are positioned at the same level and have the same width. Each channel is independently configured to accommodate its respective rail type, allowing the clamp to interface with both rail types without requiring one channel to be larger or positioned differently than the other.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Both channels are designed with the same width and are positioned at the same level, creating a symmetric and uniform structure. This homogeneous design simplifies the overall clamp structure while maintaining the ability to accommodate both Arca and Picatinnym/Weaver rail types.

Inventive Principle:

Principle #33Homogeneity
