Solution Overview

Problem

Current munition launch systems on aircraft, such as drones, require lengthy reloading times and lack safety mechanisms, posing risks during operations and compromising accuracy and safety.

Innovation Solution

A munition launcher system with a chassis, coupling mechanism, and removable ammunition tray, featuring latch pins, bolt receivers, and spring-activated fitting structures, allowing quick reloading and secure attachment during flight.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If traditional munition launch systems are used on aircraft, then the launcher can fire ammunition, but the reloading time is lengthy and the system must be removed from the aircraft to reload

Engineering Contradiction:
Improvereloading timeVSAvoidreloading operation
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The munition launch system is divided into separable components: a reusable chassis mounted on the aircraft and removable ammunition trays. This segmentation allows the trays to be quickly exchanged without removing the entire launcher from the aircraft, dramatically reducing reloading time while maintaining operational capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system employs disposable or reloadable ammunition trays that can be quickly removed and replaced. Used trays are discarded or set aside for reloading, while fresh trays are rapidly installed on the chassis. This approach eliminates the need for time-consuming in-flight reloading procedures and allows continuous operation.

Inventive Principle:
Principle #34Discarding and recovering

2Reliability

If the ammunition tray is securely attached to the chassis, then the ammunition remains safe during flight, but the attachment mechanism becomes complex

Engineering Contradiction:
Improveattachment securityVSAvoidattachment mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The attachment mechanism uses a hierarchical locking system where latch pins provide primary retention, bolt receivers provide secondary securing, and additional safety features provide tertiary protection. This nested approach ensures redundant security without requiring an overly complex single-system design.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The design incorporates safety features that prevent accidental detachment before it can occur. Latch pins are positioned to engage automatically upon tray installation, and the bolt receiver system is designed to prevent unintended release. These preemptive safety measures ensure secure attachment without requiring complex active monitoring systems.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Productivity

If the launcher is designed for quick reloading, then the reloading speed increases, but the safety mechanisms may be compromised

Engineering Contradiction:
Improvereloading speedVSAvoidsafety mechanisms
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

By separating the ammunition trays from the chassis, the system enables rapid tray exchange without compromising safety. The segmented design allows pre-loaded trays to be prepared independently and installed quickly, while the chassis retains all critical safety and firing control systems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Safety mechanisms are built into the tray-chassis interface itself rather than requiring separate safety systems. The latch pins and bolt receivers are designed to ensure positive engagement and secure retention during high-speed exchange operations, providing inherent safety that does not slow down the reloading process.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

4Ease of operation

If the coupling mechanism uses movable fitting structures with springs and bearings, then the tray can be easily coupled and decoupled, but the structure becomes more complex

Engineering Contradiction:
Improvetray couplingVSAvoidcoupling mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The coupling mechanism transitions from static rigid connections to dynamic movable fitting structures. Springs provide flexible engagement force that accommodates manufacturing tolerances and assembly variations, while bearings enable smooth lateral movement during tray installation and removal. This dynamic design simplifies operation despite the added mechanical components.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spring-activated fitting structures automatically engage and disengage during tray coupling and decoupling operations. The springs provide the necessary force to guide latch pins into opening slots without requiring manual adjustment or complex actuation mechanisms, making the system self-regulating and easier to operate.

Inventive Principle:
Principle #25Self-service
