Solution Overview

Problem

Existing gas-powered guns with internal compressed gas sources have limited firing power and an unappealing visual appearance, while those with external sources are easily identifiable.

Innovation Solution

A gas-powered gun design featuring a detachable plenum module below the barrel, which houses a plenum chamber and connects to a pressure chamber via a regulator, providing increased firing power and a visually integrated gas source resembling a magazine.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If the compressed gas source is arranged internally around the barrel, then the visual appearance resembles a real gun, but the firing power is very limited

Engineering Contradiction:
Improvevisual appearanceVSAvoidfiring power
Core Design Contradiction:
ShapeVSPower

Solution Approach 1:

The plenum chamber is nested within a detachable module that attaches to the lower part of the gun body, creating a nested structure where the gas storage system is contained within a housing that itself attaches to the main gun structure. This allows internal gas storage without compromising firing power.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The gas source is moved from the traditional lateral or top position to the lower dimension of the gun, attaching below the barrel. This dimensional relocation allows the gas source to be visually integrated while providing sufficient volume for adequate firing power.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Power

If the plenum chamber volume is increased to provide higher firing power, then the firing power is improved, but the visual appearance becomes less integrated

Engineering Contradiction:
Improvefiring powerVSAvoidvisual integration
Core Design Contradiction:
PowerVSShape

Solution Approach 1:

The gas storage system is segmented into a permanent pressure chamber within the gun body and a detachable plenum module that can be attached or removed. This segmentation allows the plenum volume to be optimized for power while maintaining a clean integrated appearance when the module is attached.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The plenum module is designed to be detachable, allowing dynamic reconfiguration of the system. Users can attach the module when high power is needed and remove it when aesthetic appearance is the priority, providing dynamic adaptability between performance and appearance modes.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If a detachable plenum module is provided, then interchangeable modules with different volumes and appearances may be used, but the device complexity increases

Engineering Contradiction:
Improvemodule interchangeabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The detachable module interface is designed as a universal connection system that can accommodate different plenum module configurations. The standardized interface allows various modules with different volumes, materials, and aesthetic features to be interchangeably mounted on the same gun platform.

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

Solution Approach 2:

Different plenum modules can be manufactured with varying parameters such as chamber volume, wall thickness, material composition, and aesthetic finishes. These parameter variations allow customization for different performance and appearance requirements while using the same base interface design.

Inventive Principle:
Principle #35Parameter changes

AI summary

A gas-powered gun comprising an inner barrel (31), a compartment (40) for compressed gas formed coaxially around the inner barrel (31), a pressure regulator (42) connected between the compartment (40) and a pressure chamber (10), so as to ensure a controlled pressure in the pressure chamber (10), and a valve (15) arranged to release compressed gas from the pressure chamber (10) to thereby discharge a projectile (13) provided in said inner barrel (31). The gas-powered gun further comprises a plenum chamber (70) in fluid connection with the pressure chamber (10), the plenum chamber being formed in a detachable module (7) arranged below the barrel during normal use.
