Solution Overview

Problem

Conventional beanbags used for firearm stabilization in long distance shooting add bulk and noise when moved, compromising stealth and convenience for snipers and tactical shooters.

Innovation Solution

A firearm support device with beanbags directly mounted to a rifle stock, allowing them to pivot between a secured transportation position and a support position, using cinch and stirrup straps, elastic cords, and various fastening mechanisms for secure and silent deployment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If beanbags are carried separately as loose gear, then they can be easily managed and packed, but they add bulk and noise during movement between shooting positions

Engineering Contradiction:
Improveease of managementVSAvoidnoise and bulk during movement
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The beanbags are merged with the rifle stock by directly mounting them to the weapon's sling mounts using straps or cords. This integration eliminates the need to carry beanbags as separate loose gear, reducing bulk and noise during movement while maintaining ease of access and management as part of the weapon system.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If beanbags are tethered to the weapon with straps or cords, then they remain accessible during movement, but they bounce and flail about creating noise and movement

Engineering Contradiction:
Improveaccessibility during movementVSAvoidnoise and movement during stealth movement
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The beanbags are mounted with dynamic positioning capability, allowing them to be secured in a compact position during movement and quickly deployed to a support position at the shooting location. The mounting system includes straps or cords that allow the beanbags to be held against the stock during movement, then released for deployment when needed, transitioning from a restrained to a functional state.

Inventive Principle:
Principle #15Dynamics

3Productivity

If beanbags are mounted directly to the rifle stock, then gear management is simplified and deployment is quick, but the mounting mechanism must be secure and silent

Engineering Contradiction:
Improvedeployment speedVSAvoidnoise during deployment
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The beanbags are pre-mounted to the rifle stock in a secured position using straps or cords attached to the weapon's sling mounts. This preliminary mounting action ensures they are ready for immediate deployment without requiring separate packing or carrying actions. The pre-attached mounting mechanism allows for quick, silent deployment by simply releasing the restraint, eliminating noise associated with unpacking or assembling the support device in the field.

Inventive Principle:
Principle #10Preliminary action

AI summary

The firearm support device includes one or more “beanbags” directly mounted to a rifle stock that can be moved between a secured transportation position held against the stock and a support position suspended beneath the stock. The support device includes a stock attachment and one or more beanbags pivotally connected to the stock attachment. The stock attachment includes cinch and stirrup straps that secure the support devices to the stock and prevent it from inadvertently sliding up the stock. The bean bags are constructed of cloth pouches filled with a granular substance. The beanbags are sewn directly to the cinch strap or connected to the cinch strap by a slide buckle that rides along a rail strap sewn to a beanbag. The beanbags are securely held against the sides of the rifle stock in the transportation position by elastic cords, buckles, snaps, hook and loop fastening patches or other connection mechanisms.
