Solution Overview

Problem

Current methods for detecting floating layers on sea surfaces near coastal facilities, such as power plants, are limited by their temporal and spatial constraints, and lack the ability to characterize the composition of these layers, leading to potential clogging of drum screens and shutdowns in cooling systems.

Innovation Solution

The use of satellite radar measurements to detect and characterize floating layers by analyzing swell profiles and fluid properties, allowing for the identification of undesirable elements and issuing warnings to prevent clogging, while being independent of cloud cover and time of day.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If aerial surveillance flyovers are used to monitor sea surfaces, then floating layers can be detected, but the monitoring is limited temporally and spatially and requires daylight

Engineering Contradiction:

Improvedetection capabilityVSAvoidmonitoring coverage

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent replaces mechanical aerial surveillance systems with satellite radar imaging. The radar system uses electromagnetic waves to detect floating layers, eliminating the need for daylight and human operators. This substitution enables continuous monitoring regardless of time of day or weather conditions, directly resolving the contradiction between detection reliability and monitoring versatility.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The satellite radar system performs multiple functions: it detects floating layers, characterizes their composition through swell profile analysis, and operates in all weather conditions and at all times. This multi-functionality allows a single system to replace multiple specialized monitoring approaches, achieving both reliable detection and comprehensive adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If aerial surveillance is established to detect floating layers, then crisis situations can be managed, but preventive detection cannot be achieved

Engineering Contradiction:

Improvecrisis management capabilityVSAvoidresponse time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The satellite radar system continuously monitors sea surfaces and detects floating layers before they reach coastal facilities. By identifying threats in advance and characterizing their composition, the system enables preventive actions to be taken, eliminating the need to wait for crisis situations to develop. This preliminary detection and characterization capability directly addresses the time loss in responding to floating layer threats.

Inventive Principle:

Principle #10Preliminary action

3Loss of information

If floating layers are detected without characterizing composition, then presence can be identified, but the ability to anticipate clogging risk is limited

Engineering Contradiction:

Improvedetection informationVSAvoidclogging risk prediction

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The patent applies local quality analysis by examining specific characteristics of floating layers at different locations. Through swell profile analysis, the system determines local composition properties (organic vs. inorganic materials) and uses this localized information to predict clogging risks for specific facilities. This approach transforms generic detection data into location-specific risk assessments.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system changes the parameters of detection by analyzing swell profiles and fluid properties rather than simply detecting presence. By measuring wave characteristics and interpreting fluid properties, the system extracts compositional information that enables reliable prediction of clogging risks, transforming basic detection into informative characterization.

Inventive Principle:

Principle #35Parameter changes

AI summary

A method and system for detecting a floating layer on a surveillance area of the sea surface, a site of interest being placed in or around the surveillance area. The method comprises the following steps: a) satellite measurement of a radar feedback return, the radar signal being emitted by a satellite toward the sea surface of the surveillance area; b) recognition of at least one swell profile of the sea surface in accordance with the satellite measurements; c) identification of the fluid properties corresponding to the recognized swell profiles; and d) emission of a warning when the fluid properties identified for one of the recognized profiles correspond to a sea surface that includes undesirable elements for the site of interest.
