Solution Overview

Problem

In metallurgical processes, precise positioning of metallurgical vessels is challenging due to decimeter-level tolerances, leading to manual compensation and increased health risks for operators, while existing optical sensors are unreliable in harsh environments, affecting process stability and cycle times.

Innovation Solution

A system using a robot with a positioning means that engages with a position element on the metallurgical vessel via contact, utilizing a touch sensor to measure forces and moments for accurate positioning, allowing the robot to determine its position independently and safely, even in conditions like vapor or smoke, without operator intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If optical sensors are used to automate robot positioning at metallurgical vessels, then automation extent is improved, but measurement precision deteriorates due to environmental conditions like steam and smoke

Engineering Contradiction:
Improveautomation of robot positioningVSAvoidposition determination accuracy
Core Design Contradiction:
Extent of automationVSMeasurement precision

Solution Approach 1:

The patent replaces optical sensing systems with a mechanical positioning system. A robot equipped with a positioning means (mechanical probe) physically contacts a positioning element (target) on the metallurgical vessel to determine position. This mechanical contact-based approach is immune to environmental conditions like steam and smoke that plague optical sensors, thereby maintaining measurement precision while achieving full automation.

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

2Measurement precision

If manual positioning of the robot is performed by an operator, then measurement precision is improved through direct observation, but object-affected harmful factors worsen due to operator exposure to hazards

Engineering Contradiction:
Improveposition determination accuracyVSAvoidoperator safety risks
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The system enables the robot to perform self-positioning through automatic contact with the positioning element on the metallurgical vessel. The robot autonomously moves its positioning means to contact the target, detects the contact position, and adjusts accordingly without operator intervention. This eliminates operator exposure to hazardous environments while maintaining precise position determination through the mechanical contact method.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If manual positioning compensation is performed to achieve precise positioning, then manufacturing precision is improved, but loss of time increases due to extended positioning procedures

Engineering Contradiction:

Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent replaces manual positioning compensation procedures with an automated mechanical positioning system. The robot autonomously contacts the positioning element, detects the contact position through force sensors or position sensors, and automatically adjusts its position. This eliminates the time-consuming manual observation and adjustment process while maintaining high positioning accuracy, thereby reducing cycle times.

Inventive Principle:

Solution Approach 1:

The patent substitutes optical detection systems with a mechanical contact-based detection system. The robot's positioning means physically contacts the positioning element on the metallurgical vessel, and position is determined through mechanical interaction detected by force sensors or position sensors. This mechanical approach provides reliable data acquisition in harsh environments with steam, smoke, and extreme temperatures where optical sensors fail, while maintaining ease of remote operation.
