Solution Overview

Problem

Firearm structures, particularly shotguns, suffer from reduced hit ratio and firepower due to smooth interior barrel surfaces, which contrasts with the rotational surfaces of rifles that enhance shooting performance.

Innovation Solution

A new firearm mechanism designed for both rifles and shotguns features a lock system operating in a perpendicular position with a lower recoil level and increased firing power through minimal gas leakage, incorporating a mechanism group with a recoil spring tube, firing pin, and extractor system that interacts with the barrel to enhance firing efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If smooth interior barrel surface is used in shotguns, then ease of manufacture is improved, but hit ratio and firepower deteriorate

Engineering Contradiction:
Improveease of manufactureVSAvoidhit ratio
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent applies local quality by creating rotational surfaces only in specific zones where needed for performance. The barrel interior has rotational surfaces in the firing zone to improve hit ratio, while other portions maintain smooth surfaces for ease of manufacture. This selective application of surface treatment resolves the contradiction between manufacturing simplicity and shooting performance.

Inventive Principle:
Principle #3Local quality

2Reliability

If rotational interior barrel surface is used, then hit ratio and firepower are improved, but manufacturing complexity increases

Engineering Contradiction:
Improvehit ratioVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the barrel interior surface treatment into distinct zones. Rather than applying rotational surfaces to the entire barrel interior, only specific segments receive this treatment. This segmentation reduces manufacturing complexity while maintaining the performance benefits in critical areas.

Inventive Principle:
Principle #1Segmentation

3Power

If lock system operates in perpendicular position, then firing power is increased, but gas leakage increases

Engineering Contradiction:
Improvefiring powerVSAvoidgas leakage
Core Design Contradiction:
PowerVSLoss of energy

Solution Approach 1:

The patent converts the potential harm of gas leakage into a benefit by designing the perpendicular lock system to control and direct gas flow. The gas leakage that occurs is channeled to enhance firing power in a controlled manner, transforming energy loss into useful propulsion force.

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

4Power

If perpendicular lock system is implemented, then firing power increases, but recoil increases

Engineering Contradiction:
Improvefiring powerVSAvoidrecoil
Core Design Contradiction:
PowerVSForce

Solution Approach 1:

The patent employs counterweight principles by designing the perpendicular lock system to balance recoil forces. The lock system's perpendicular orientation creates counteracting forces that offset the rearward recoil impulse, allowing high firing power to be achieved without excessive recoil affecting accuracy or shooter comfort.

Inventive Principle:
Principle #8Anti-weight (Counterweight)
