Solution Overview

Problem

Monitoring the operation of automatic or autonomous equipment, especially in hard-to-reach areas, is challenging due to difficulties in verifying calculated positions, which can lead to positional deviations and unforeseen incidents when components are damaged or loose.

Innovation Solution

A method and device that utilize non-contact transmitters to convert signals into comparable picture information, compare calculated positions with real positions at a pixel level, and calculate deviations, providing a more reliable position measurement and warning system, even in inaccessible locations like the seabed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If position verification is performed in hard-to-reach areas, then measurement precision is improved, but device complexity increases due to the need for non-contact transmitters and 3D modeling systems

Engineering Contradiction:
Improveposition verification accuracyVSAvoidmonitoring system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces physical contact-based measurement systems with non-contact transmitters (cameras, lasers) that capture optical or electromagnetic signals. This substitution enables position verification in hard-to-reach areas without mechanical intervention, resolving the contradiction by improving measurement precision while avoiding the complexity of physical access systems

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

Solution Approach 2:

The patent creates a virtual 3D model (copy) of the equipment and its environment that mirrors the physical system. This digital twin allows position verification through comparison of calculated positions with actual captured images, enabling accurate measurement without physical access to difficult locations

Inventive Principle:
Principle #26Copying

2Reliability

If non-contact transmitters are deployed to monitor inaccessible areas, then reliability is improved, but loss of information increases due to the need for complex signal conversion and comparison processes

Engineering Contradiction:
Improveposition monitoring reliabilityVSAvoiddata processing accuracy
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent implements a feedback loop where non-contact transmitters continuously capture position data, compare it with the 3D model's calculated position, and generate deviation warnings. This closed-loop system improves reliability by continuously verifying position accuracy and providing real-time correction alerts

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces a processing unit as an intermediary that bridges the gap between raw transmitter signals and meaningful position verification. This intermediary converts and compares data from different sources (calculated position vs. actual position), preventing information loss through systematic data reconciliation

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If continuous position monitoring is implemented, then safety is improved, but use of energy increases due to continuous operation of transmitters and processing systems

Engineering Contradiction:
Improvesafety incidentsVSAvoidmonitoring system energy consumption
Core Design Contradiction:
Object-affected harmful factorsVSUse of energy by moving object

Solution Approach 1:

The patent employs periodic monitoring cycles where non-contact transmitters capture positions at intervals rather than continuously. The system compares calculated positions with actual positions periodically and triggers warnings only when deviations exceed thresholds, reducing energy consumption while maintaining safety through regular verification

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses the equipment's own control system data (calculated positions from 3D models) as a reference for self-verification. By comparing self-calculated positions with externally captured positions, the system achieves safety monitoring without requiring additional active sensors at the monitored location, reducing overall energy consumption

Inventive Principle:
Principle #25Self-service
