Solution Overview

Problem

Dual-feed weapons with link deflector devices face issues where links ejected from one port obstruct the other ejection route, leading to potential firing incidents due to restricted space and fixed deflector installation challenges.

Innovation Solution

A link deflector device with a deflector flap connected via a ball joint and horizontal slide connection between two ejection orifices, allowing the flap to pivot and translate to prevent obstruction, ensuring unimpeded ejection of links from either channel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed deflector is installed between ejection ports, then link ejection is directed away from the other port, but the restricted space between ejection ports complicates installation and the deflector cannot adapt to dynamic ejection patterns

Engineering Contradiction:
Improveprevention of ejection port blockageVSAvoidinstallation complexity due to restricted space
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the deflector flap movable rather than fixed. The flap is articulated to the weapon structure and can pivot dynamically in response to link ejection forces. This allows the deflector to adapt its position automatically during operation, optimizing link redirection while accommodating the restricted space between ejection ports without complex installation requirements.

Inventive Principle:
Principle #15Dynamics

2Productivity

If links are ejected from one port, then they are directed towards the other port by fixed deflectors, but this causes accumulation and obstruction of the ejection path

Engineering Contradiction:
Improvelink ejection efficiencyVSAvoidlink accumulation and obstruction
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent applies the 'blessing in disguise' principle by utilizing the kinetic energy and directional force of ejected links, which would normally cause obstruction, to actively push the deflector flap into its proper deflecting position. The harmful impact of links against a fixed deflector is converted into a beneficial self-actuating mechanism that optimizes link redirection and prevents accumulation in the ejection path.

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

Solution Approach 2:

The movable flap dynamically adjusts its position based on the force and direction of incoming links, creating an adaptive system that redirects links away from the other ejection port while preventing accumulation. This dynamic adjustment eliminates the obstruction problem that occurs with fixed deflectors.

Inventive Principle:
Principle #15Dynamics

3Area of stationary object

If a fixed deflector is used to redirect links, then space requirements are minimized, but the deflector cannot adapt to different ejection conditions and may cause obstruction

Engineering Contradiction:
Improvespace between ejection portsVSAvoidadaptation to different ejection conditions
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The patent resolves this contradiction by implementing a movable, articulated deflector flap that maintains a compact footprint while adapting to different ejection conditions. The flap's ability to pivot and reposition itself allows it to handle varying link ejection patterns, forces, and directions without requiring additional space, thus maintaining adaptability within the constrained area between ejection ports.

Inventive Principle:
Principle #15Dynamics
