Solution Overview

Problem

Existing torpedo storage and launch systems are complex, expensive, and require compressed air and an operator for launch, making them unsuitable for simple and inexpensive defensive measures in areas without surveillance agents or deployed defensive weapons, especially in uneven sea floors like those with rocks.

Innovation Solution

A sea-based buoyancy type torpedo storage and launch system featuring a vertically arranged torpedo with a buoyant rise mechanism, using hydrogen and oxygen gas balloons for buoyancy and automatic detection and launch, allowing the torpedo to rise and collide with targets without a propulsion apparatus, and being designed to evade detection by sonar and radar.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional torpedo storage and launch system is used, then the system can launch torpedoes, but the configuration becomes complicated and expensive, requiring compressed air tanks and operators

Engineering Contradiction:
Improvetorpedo launch capabilityVSAvoidsystem configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts and removes the compressed air tank and propulsion apparatus from the torpedo system, retaining only the essential launch capability through buoyancy-based rise mechanism. This simplifies the overall system configuration while maintaining the core function of torpedo deployment.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The torpedo utilizes its own buoyancy to rise and propel itself upward after launch, eliminating the need for external compressed air propulsion. The system serves itself by using inherent physical properties (buoyancy) rather than requiring complex external propulsion systems.

Inventive Principle:
Principle #25Self-service

2Reliability

If a conventional torpedo storage and launch system is used, then the system can launch torpedoes, but it requires an operator and large-scale apparatus

Engineering Contradiction:
Improvetorpedo launch capabilityVSAvoidoperator requirement
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The torpedo storage and launch apparatus automatically detects target ships using sonar or radar and launches torpedoes without human intervention. The system performs detection, decision-making, and launch operations autonomously, eliminating the need for operators while maintaining reliable torpedo deployment capability.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the torpedo storage and launch apparatus is made detectable by sonar or radar, then the system can be located and operated, but it becomes vulnerable to detection and countermeasures by enemy ships

Engineering Contradiction:
Improvesystem locationVSAvoiddetection vulnerability
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention applies acoustic and electromagnetic wave absorption materials to the outer surface of the torpedo storage and launch apparatus, analogous to changing its 'acoustic color' or 'electromagnetic color'. This allows the system to absorb rather than reflect sonar and radar waves, making it undetectable by enemy detection systems while maintaining operational capability.

Inventive Principle:
Principle #32Color changes

AI summary

The present invention provides a simple and inexpensive torpedo storage and launch system that has a sea-based buoyancy type torpedo storage and launch system that has a torpedo storage and launch apparatus that stores a buoyant rise type torpedo in vertical arrangement, and further has a torpedo launch mechanism unit that has an outer peripheral surface made of a material that minimizes electric or acoustic wave reflection, that is arranged on the sea floor, whereby automatic ship detection is performed by remote control from a radar station or the like or by a sonar and controlling means provided in the torpedo storage and launch apparatus itself so that if a ship comes into an encounter position and time then the torpedo is launched from the sea floor, rises by buoyancy, and detonates on collision with the ship, thereby torpedoing the ship.
