Solution Overview

Problem

Existing firearm stabilizers typically support the firearm at only one point, leading to increased instability due to user body movement, particularly at the rear end.

Innovation Solution

A stabilizer system with a support extending upwardly from a surface and a flexible strap affixed to its upper end, which is grasped by the user to apply force and sandwiched between the firearm grip and palm, providing additional stability by bracing against the surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single-point support system is used, then the device complexity is reduced, but the stability of the firearm during firing deteriorates

Engineering Contradiction:
Improvestabilizer structureVSAvoidfirearm stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The stabilizer is divided into two separate components: a support structure that provides physical stabilization and a strap that provides user-controlled bracing. This segmentation allows each component to perform its specific function optimally while maintaining overall system simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The strap acts as an intermediary element between the user's hand and the support structure. It transfers the user's bracing force to the support, enabling controlled stabilization without requiring direct hand contact with the support structure itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If a second point of stabilization is added at the rear end, then the stability of the firearm improves, but the device complexity increases

Engineering Contradiction:
Improvefirearm stabilityVSAvoidstabilizer structure
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The stabilizer system is segmented into a support structure for passive stabilization and a strap mechanism for active user control. This division allows the second point of stabilization to be achieved through a simple, add-on component rather than a complex integrated system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The strap provides dynamic, user-adjustable stabilization rather than fixed structural support. This allows the system to adapt to different firing positions and user needs while maintaining simplicity through flexible rather than rigid design.

Inventive Principle:
Principle #15Dynamics

AI summary

A device for stabilizing a firearm comprises a support extending upwardly from a surface. A flexible strap flexibly affixed to an upper end of the support is grasped by a user and sandwiched between the grip of the firearm and the palm of his firing hand. The user applies a force on the strap in a direction toward the surface to brace the support against the surface and add stability to the rear of the firearm.
