Solution Overview

Problem

Existing search and rescue equipment at sea lacks mobility and navigational capabilities in adverse conditions, limiting its effectiveness in reaching shipwrecked individuals, especially when the device is upside down or not positioned correctly.

Innovation Solution

A U-shaped self-propelled craft with two turbines and a robust remote control system, equipped with an electronic module including a magnetometer, accelerometer, GPS, and propulsion system, allowing navigation on any side and automatic water intake adjustment, enabling reliable and efficient rescue operations in rough seas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a traditional circular buoy is used, then it provides basic floating support, but it lacks mobility and cannot navigate to shipwrecked persons in adverse sea conditions

Engineering Contradiction:
Improvenavigation speedVSAvoiddevice structure
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The craft is divided into two symmetrical halves (left and right) that can function independently or together. Each half contains its own turbine, water inlet, and propulsion system, allowing the craft to be operated as a complete unit or split into separate rescue devices.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The craft serves multiple functions: it can navigate to shipwrecked persons, provide floating support, be launched from various platforms (land, sea, air), and operate in any orientation. The symmetrical design with dual turbines enables it to perform rescue operations regardless of which side enters the water first.

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

2Adaptability or versatility

If the craft is designed to navigate only in a specific position, then the structure is simpler, but it cannot operate when upside down or not correctly positioned

Engineering Contradiction:
Improvenavigation orientationVSAvoidwater inlet system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

While the overall craft is symmetrical, each half contains asymmetric components (turbine, water inlet, ejection opening) positioned to function optimally when that half is in the correct orientation. The symmetry of the whole combined with asymmetry of parts allows operation in any orientation.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The craft dynamically adapts its water intake system based on orientation. Each half has water inlets and ejection openings positioned to function whether the craft is right-side up, upside down, or entering water from any direction, allowing continuous operation regardless of position.

Inventive Principle:
Principle #15Dynamics

3Reliability

If a robust remote control system with multiple sensors is added, then navigation and control reliability improves, but the device complexity increases

Engineering Contradiction:
Improveremote control reliabilityVSAvoidelectronic module
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The electronic module with magnetometer, accelerometer, and gyroscope enables the craft to autonomously determine its orientation and position. This self-service capability reduces the burden on the remote operator and improves reliability by providing automatic navigation assistance.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The sensor suite provides continuous feedback about the craft's orientation, position, and motion state to the remote control system. This feedback loop enables the operator to make informed control decisions and the system to automatically adjust for optimal performance.

Inventive Principle:
Principle #23Feedback

4Volume of moving object

If the craft is made with reduced dimensions for easy storage, then storage versatility improves, but the propulsion power may be limited

Engineering Contradiction:
Improvestorage sizeVSAvoidpropulsion power
Core Design Contradiction:
Volume of moving objectVSPower

Solution Approach 1:

The craft can be stored in a compact form on land, sea, or air platforms and quickly deployed when needed. The modular design allows it to be stored in reduced dimensions while maintaining full propulsion capability when deployed.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The craft operates in periodic cycles of deployment and storage. When deployed, the full propulsion power is available for rapid response; when not in use, it is stored in compact form. The dual turbine system provides sufficient power during operational periods despite the small overall size.

Inventive Principle:
Principle #19Periodic action

AI summary

The present invention relates a self-propelled craft with a U-shaped main body provided with two turbines (7), one on each flap (2) of the U-shaped main body, which propel the self-propelled craft (1) through turbine operation in a chamber (8) fed by water received by water intakes (4) which is ejected by the ejection openings (3), and which turbines (7) move inside the turbine operation chamber (8) adopting automatically one of two possible positions due to the casing (15) which is placed in two different positions within the turbine operation chamber (8), which positioning results from the placement of the device on the water being done by side A or B, the water intake being done through existing water entrances (4) on side A or B of the device.
