Solution Overview

Problem

Existing firearms, particularly rifles, are heavy, generate significant recoil and gaseous discharge, and lack versatility, which hinders precision and long-range shooting performance.

Innovation Solution

The design of an actionless rifle with an exo-bolt mechanism, a collapsible stock, and a retractable suppressor, combined with a muzzle brake that redirects gas discharge, and a reticle featuring a density altitude guide and wind compensation, to enhance shooting accuracy and reduce weight and recoil.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional rifles are used for precision shooting, then shooting accuracy can be achieved, but the rifle weight and recoil increase

Engineering Contradiction:
Improveshooting accuracyVSAvoidrifle weight
Core Design Contradiction:
Measurement precisionVSWeight of moving object

Solution Approach 1:

The patent removes the traditional rifle action (trigger mechanism, bolt, magazine) and replaces it with an actionless design where the barrel is directly mounted on the stock. This extraction of unnecessary components significantly reduces rifle weight while maintaining shooting accuracy through the retained essential elements: barrel, stock, and simplified firing mechanism.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The rifle is segmented into minimal essential components: barrel, stock, and actionless firing mechanism. This segmentation eliminates redundant parts that contribute to weight while preserving the core functions needed for precision shooting.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If traditional rifles are used for long-range shooting, then precision can be achieved, but gaseous discharge and visual disturbances increase

Engineering Contradiction:
Improvelong-range shooting precisionVSAvoidgaseous discharge
Core Design Contradiction:
Measurement precisionVSObject-generated harmful factors

Solution Approach 1:

The patent employs a muzzle brake device that captures and redirects the harmful gaseous discharge from the barrel muzzle. The brake converts the harmful gas flow into beneficial rearward-directed thrust that counteracts recoil, while also reducing the forward gaseous discharge that causes visual disturbances for the shooter.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The muzzle brake is positioned at the barrel muzzle to preemptively intercept and redirect gas discharge before it can create harmful visual disturbances or excessive recoil. This preliminary anti-action prevents the harmful effects before they impact the shooter.

Inventive Principle:
Principle #9Preliminary anti-action

3Adaptability or versatility

If traditional rifles are used, then basic shooting function is provided, but versatility for different shooting conditions is limited

Engineering Contradiction:
Improveshooting condition adaptabilityVSAvoidrifle system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The actionless rifle design provides universal adaptability across different shooting conditions by eliminating condition-specific mechanical actions. The simplified system with direct-barrel mounting and modular muzzle brake works effectively across various ranges and scenarios without requiring complex adjustment mechanisms, making the system universally applicable while remaining simple.

Inventive Principle:
Principle #6Universality (Multi-functionality)
