Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing firearm configurations with reciprocating slides face challenges in efficiently assembling and disassembling recoil systems, particularly those involving guide rods and springs, due to their complex interdependencies and lack of compatible catch mechanisms.

Innovation Solution

The introduction of a recoil system with a slide plug catch means and plug retainer catch means that interfit, allowing the recoil system to be held in a partially compressed configuration, facilitating easy removal and assembly by interlocking these components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional guide rod and spring configurations are used, then the recoil system can function, but the assembly and disassembly process becomes complex and time-consuming

Engineering Contradiction:

Improveassembly and disassembly efficiencyVSAvoidrecoil system configuration complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The recoil system is divided into separable modular components including the guide rod, spring assembly, and plug with catch means. This segmentation allows independent assembly and disassembly of components without affecting the entire system, directly improving productivity while reducing the complexity of the overall configuration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The plug with catch means acts as an intermediary component that simplifies the connection between the guide rod and spring assembly. The catch means provides a straightforward locking mechanism that enables easy assembly and disassembly operations, resolving the complexity issue while maintaining system functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the recoil system is designed with fixed configuration, then structural stability is maintained, but adaptability for different firearm designs is reduced

Engineering Contradiction:

Improverecoil system adaptabilityVSAvoidrecoil system configuration stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The guide rod and spring assembly are designed with universal features that allow them to function in multiple firearm configurations. The standardized interface with the plug and catch means enables the same components to be adapted to different firearm designs while maintaining structural stability through consistent mechanical engagement.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The recoil system incorporates dynamic elements through the movable plug and catch means mechanism, allowing the system to transition between locked and unlocked states. This dynamic design provides adaptability for different configurations while maintaining stability during operation through the secure catching mechanism.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If the guide rod is disposed through an opening in the plug, then the structure is simplified, but reliable retention of the spring requires additional catch mechanisms

Engineering Contradiction:

Improvestructural simplicityVSAvoidspring retention reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The plug integrates multiple functions into a single component: it provides structural support, defines the guide rod passage, and incorporates the catch means for spring retention. This merging maintains structural simplicity while ensuring reliable spring retention through the integrated catch mechanism that positively engages with the guide rod.

Inventive Principle:

Principle #5Merging (Combining)
