Solution Overview

Problem

Traditional portable weapons have a complex assembly process with many components that can be easily lost or misassembled, requiring screws and threaded caps, leading to a cumbersome and unreliable disassembly and reassembly.

Innovation Solution

A modular design where components like the supporting module, locking and recocking module, stock module, containment module, and magazine module engage through claws and quick coupling systems without screws, allowing for independent assembly and disassembly without tools, with each module performing distinct functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional portable weapons use a complex assembly with many components (frame, magazine tube, locking assembly, barrel, guide rod, threaded cap), then the weapon can be disassembled into individual parts, but the components are not mutually connected and can be easily lost, and the assembly process is cumbersome

Engineering Contradiction:
Improvemodular configurabilityVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The weapon is divided into distinct functional modules (barrel module with locking assembly, stock module, magazine module, sight module) that can be independently assembled and disassembled. Each module maintains its functional integrity while enabling modular reconfiguration, directly resolving the contradiction between adaptability and complexity by organizing components into meaningful functional units rather than loose individual parts

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking assembly is nested within the barrel module, and the magazine module contains the cartridge feed mechanism. This nesting ensures that when modules are disassembled, their internal components remain contained within their respective module housings, preventing loss of small components while maintaining modular separability for reconfiguration

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If traditional portable weapons use screws and threaded caps for assembly, then components can be securely fastened, but the assembly and disassembly process requires tools and becomes time-consuming

Engineering Contradiction:
Improveassembly reliabilityVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The traditional screw-and-threaded-cap mechanical fastening system is replaced with a bayonet-style quarter-turn locking mechanism. This substitution maintains secure fastening (reliability) while eliminating the need for tools and significantly reducing assembly time from minutes to seconds, directly resolving the contradiction between reliability and assembly time

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The locking surfaces and alignment features are pre-configured on the module interfaces during manufacturing. The bayonet locking geometry is predetermined to ensure proper alignment and secure engagement, eliminating the need for complex assembly procedures or tools while maintaining reliable connection, thus resolving the time-reliability contradiction

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If traditional portable weapons disassemble into individual components, then the weapon can be stored or transported in parts, but the components are not mutually connected and can be easily lost

Engineering Contradiction:
Improvedisassembly easeVSAvoidcomponent retention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Each module contains its internal components nested within its housing structure. When the weapon is disassembled into modules, small components like springs, pins, and locking elements remain contained within their respective module housings, preventing loss while maintaining ease of module-level disassembly for storage and transport

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

Functionally related components are merged into integrated modules. For example, the locking assembly is combined with the barrel module, and the magazine feed mechanism is integrated with the magazine module. This merging ensures that disassembly produces connected functional units rather than loose individual parts, resolving the contradiction between ease of disassembly and component retention

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A modular portable weapon has a supporting module (100), constituted by the barrel (1) of the weapon, and modules which are mutually functionally independent and are associated with the supporting module. The modular weapon according to the invention allows the user to compose the weapon by choosing, for example, a type of barrel, stock and tubular magazine among the alternatives that are commercially available, with the characteristics best suited to his requirements.
