Solution Overview

Problem

Existing carrier platforms face challenges in accommodating missiles with large control surface elements due to stealth requirements, leading to issues with installation space and the inability to return missiles to the launcher after launch preparation is aborted.

Innovation Solution

A carrier platform with a reversible transfer mechanism for missiles and control surface elements, allowing the control surface elements to be folded in for compact storage and unfolded for launch, while enabling the missile to be returned to the launcher if needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If missiles are accommodated in a shaft-like receiving device to maintain stealth properties, then the stealth characteristics are improved, but the mounting system requires sufficiently large dimensions that may not be available due to installation space constraints

Engineering Contradiction:
Improvestealth characteristicsVSAvoidmounting system dimensions
Core Design Contradiction:
Object-affected harmful factorsVSVolume of stationary object

Solution Approach 1:

The control surface elements are divided into multiple segments that can be folded independently. The first control surface element has a first segment and a second segment, while the second control surface element has a third segment and a fourth segment. This segmentation allows the control surfaces to be folded into a compact configuration for stealth mode while maintaining full functionality when deployed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control surface elements are designed with dynamic folding capability, transitioning between extended and folded states. The reversible folding mechanism allows the control surfaces to adapt their configuration based on operational requirements, being extended for flight control and folded for compact storage in the receiving device.

Inventive Principle:
Principle #15Dynamics

2Volume of stationary object

If missiles with fold-out control surface elements are used to reduce mounting system dimensions, then the installation space requirement is reduced, but the control surface elements cannot be folded back in, preventing the missile from being returned to the launcher

Engineering Contradiction:
Improvemounting system dimensionsVSAvoidmissile return capability
Core Design Contradiction:
Volume of stationary objectVSAdaptability or versatility

Solution Approach 1:

The control surface elements incorporate a reversible folding mechanism that allows bidirectional movement between extended and folded states. The first and second control surface elements can be folded out from the missile body for flight operation and then folded back in, enabling the missile to be returned to the launcher for reuse or storage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The design enables recovery of the missile system by allowing control surface elements to be folded back into the missile body after use. This reversibility prevents permanent deployment of control surfaces, allowing the missile to be recovered and returned to the launcher, thereby extending the operational lifecycle of the missile system.

Inventive Principle:
Principle #34Discarding and recovering

3Volume of stationary object

If the receiving device is designed to accommodate missiles with control surface elements folded in, then the installation space is optimized, but the missile cannot be transferred back to the launcher if a launch sequence is aborted

Engineering Contradiction:
Improvereceiving device dimensionsVSAvoidmissile transfer reversibility
Core Design Contradiction:
Volume of stationary objectVSEase of operation

Solution Approach 1:

The control surface elements are equipped with dynamic folding mechanisms that enable reversible transitions between extended and folded configurations. When a launch sequence is aborted, the control surfaces can be folded back into the missile body, allowing the missile to be transferred back to the launcher and restoring the system to its initial state.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control surface elements change their spatial configuration parameter by folding in and out. This parameter change enables the missile to adapt its dimensions for different operational states, allowing compact storage in the receiving device while maintaining the capability for reversible transfer to and from the launcher.

Inventive Principle:
Principle #35Parameter changes
