Solution Overview

Problem

Existing buttstock designs are susceptible to breakage due to mechanical stress and lack flexibility in storage functionality, requiring users to purchase multiple stocks for different applications and incur time-consuming stock swaps.

Innovation Solution

A modular buttstock assembly featuring a multi-shaft locking block and bowed or arched actuating spring for enhanced structural integrity, along with swappable rear bodies for customizable storage and accessory integration, allowing quick adaptation to various applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional Roy's adjustable buttstock design is used, then adjustability is achieved, but structural integrity and resistance to mechanical stress deteriorate

Engineering Contradiction:

ImproveadjustabilityVSAvoidstructural integrity

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The buttstock is divided into multiple segments that can slide relative to each other along the receiver extension tube. Each segment can be independently positioned and locked, allowing adjustment of the overall length while maintaining structural integrity through the segmented locking mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The buttstock transitions from a static fixed-length design to a dynamic adjustable-length design. The segments can move along the receiver extension tube and be locked into different positions, providing adaptability while maintaining strength through the locking mechanism.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If permanently integrated storage compartments are added to the buttstock, then storage functionality is improved, but structural integrity and reliability deteriorate

Engineering Contradiction:

Improvestorage functionalityVSAvoidresistance to breakage

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The storage compartment is separated from the main buttstock structure as a removable component. This allows the storage function to be added without permanently weakening the structural integrity of the buttstock, as the storage compartment can be detached when not needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The buttstock is designed to serve multiple functions: as a structural component for supporting the firearm, and as a storage container when the removable storage compartment is attached. This multi-functionality allows users to have both structural integrity and storage capability without compromising either.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple buttstocks are purchased to accommodate different applications, then functional versatility is improved, but loss of time and loss of substance increase

Engineering Contradiction:

Improvefunctional versatilityVSAvoidtime for stock swaps

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The buttstock allows dynamic adjustment of its length and configuration through the sliding and locking mechanism. Users can quickly adjust the buttstock to suit different applications without needing to swap entire stocks, saving time and effort.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

A single buttstock design provides multiple functions through adjustable length and optional storage compartment attachment. This eliminates the need for users to purchase and carry multiple different buttstocks for different applications.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If multiple buttstocks are purchased to accommodate different applications, then functional versatility is improved, but loss of substance increases

Engineering Contradiction:

Improvefunctional versatilityVSAvoidfunds spent on additional stocks

Core Design Contradiction:

Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The buttstock is designed as a universal component that can serve multiple functions through adjustable length and optional storage compartment attachment. This single multi-functional design replaces the need for multiple separate buttstocks, reducing financial expenditure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A modular buttstock assembly that removably mounts to a receiver extension of a firearm may include a main body and a rear body. The main body may have a passage that mates with the receiver extension, while the rear body may be removably coupled to the main body such that any number of swappable, modular rear bodies may be coupled to the main body. The main body may include a toggle assembly with a actuating lever coupled to an bowed or ached actuating spring. The toggle assembly may also include a locking block with a plurality of shafts that distribute the load from the receiver extension to the main body rather than concentrating mechanical stress on a single lock pin.
