Solution Overview

Problem

Existing reconnaissance methods for coastal areas, such as deploying trained operatives or using aerial drones and satellite data, are either risky, non-covert, or lack the necessary high-resolution data for effective planning of personnel and hardware deployment, particularly in hostile environments.

Innovation Solution

A system comprising a first submersible vehicle deploying a second submersible vehicle, connected via a tether, which allows independent movement and data transfer, enabling high-resolution data collection and sample acquisition with sensing equipment, and allowing re-docking and land movement for detailed coastal area assessment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If trained operatives are deployed to the intended deployment location for reconnaissance, then high-resolution data can be obtained, but the risk to the lives of operatives increases significantly

Engineering Contradiction:
Improvereconnaissance data qualityVSAvoidoperative safety
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent uses autonomous submersible vehicles as artificial copies of human operatives to perform reconnaissance tasks. These vehicles can collect high-resolution data about coastal areas, water depth, and terrain features without exposing human lives to danger, thereby resolving the contradiction between data quality and operative safety.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical system of human operatives with autonomous submersible vehicles equipped with sensors and navigation systems. This substitution allows the collection of detailed reconnaissance data while eliminating the risk to human life, as the vehicles can operate in hostile environments without vulnerability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If aerial drones are used to obtain data, then high-resolution reconnaissance can be achieved, but the operation becomes non-covert and range is significantly limited

Engineering Contradiction:
Improvereconnaissance data resolutionVSAvoiddetection risk and range limitation
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent transitions from aerial (three-dimensional air space) to underwater (three-dimensional water space) operations. Submersible vehicles operate below the surface, making them invisible to aerial surveillance and significantly extending their operational range beyond what drones can achieve, while maintaining high-resolution sensing capabilities.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent uses the ocean water column as an intermediary medium to conceal the reconnaissance vehicles from detection. By operating underwater rather than in the air, the vehicles exploit the natural barrier of water to remain covert while gathering intelligence, resolving the contradiction between detection risk and data quality.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If satellite data is used to view potential deployment locations, then covert operation is maintained, but the resolution lacks the detail required for effective operation planning

Engineering Contradiction:
Improvecovert operation capabilityVSAvoidsurface composition and obstacle detail
Core Design Contradiction:
Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The patent divides the reconnaissance task into two stages: initial broad assessment using satellite data (covert, low resolution) followed by detailed on-site investigation using submersible vehicles (covert, high resolution). This segmentation allows the operation to maintain covert status while achieving the necessary level of detail for planning, as the submersibles can approach undetected and collect granular data about surface composition and obstacles.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses satellite data to perform preliminary identification of potential deployment locations before deploying submersible vehicles for detailed reconnaissance. This preliminary action narrows down the areas of interest, allowing the high-resolution submersibles to focus their investigation on specific targets while maintaining covert operations, thus resolving the resolution limitation of satellite data.

Inventive Principle:
Principle #10Preliminary action

4Device complexity

If a single submersible vehicle is used for reconnaissance, then device complexity is reduced, but the ability to collect comprehensive data and samples is limited

Engineering Contradiction:
Improvevehicle system structureVSAvoiddata collection and sampling capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent employs a nested configuration where a smaller second submersible vehicle is deployed from within a larger first submersible vehicle. The first vehicle provides power and data link capabilities through a tether, while the second vehicle can be positioned closer to the seabed for detailed sampling and sensing. This nesting allows comprehensive data collection capabilities without requiring each vehicle to be independently complex.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The first submersible vehicle serves multiple functions: it acts as a platform for deploying the second vehicle, provides power through the tether, maintains communication links, and can recover the second vehicle after reconnaissance. This multi-functionality allows the system to achieve comprehensive data collection and sampling capabilities while keeping individual vehicle designs relatively simple, resolving the contradiction between device complexity and versatility.

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