Solution Overview

Problem

Conventional welding systems lack an efficient method for automatically generating welding instructions, which can lead to errors and increased time and resource consumption, especially for less experienced operators.

Innovation Solution

A welding system that utilizes a tracking system to monitor the position and orientation of welding tools and operators, processing this data to automatically generate welding instructions based on identified welding technique parameters, and recording these instructions for future use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual welding instruction generation is used, then flexibility and customization are maintained, but time consumption and error risk increase significantly

Engineering Contradiction:
Improveaccuracy of welding instructionsVSAvoidtime for instruction generation
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system creates digital copies of welding procedures by tracking and recording actual welding operations. These digital models can be automatically replicated and reused, eliminating the need for manual recreation of instructions while maintaining accuracy through automated data capture from sensors and tracking systems.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The welding system automatically generates its own instructional documentation by capturing operational data during welding processes. The system self-documented procedures, parameters, and techniques without requiring external manual intervention, thereby improving both accuracy through direct data capture and reducing time consumption.

Inventive Principle:
Principle #25Self-service

2Productivity

If automated welding instruction generation is implemented, then time and resource efficiency improve, but system complexity increases

Engineering Contradiction:
Improveinstruction generation efficiencyVSAvoidsystem architecture complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The welding system integrates multiple functions into a unified platform that simultaneously performs welding operations, tracks operational parameters, captures sensor data, and generates instructional documentation. This multi-functionality improves productivity by consolidating processes while managing complexity through integrated architecture rather than separate systems.

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

Solution Approach 2:

The system merges the welding execution process with the instruction generation process into a single coordinated operation. By combining data capture, analysis, and documentation generation within the welding workflow itself, the system achieves high efficiency without proportionally increasing complexity, as the same hardware and software resources serve dual purposes.

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If detailed tracking of tool position and orientation is performed, then welding technique parameter accuracy improves, but data processing complexity increases

Engineering Contradiction:
Improvetool position and orientation accuracyVSAvoiddata processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system extracts only the essential welding technique parameters from the complete set of tracked data, such as tool position, orientation, and movement velocity. By selectively extracting relevant information rather than processing all available data, the system maintains high measurement precision for critical parameters while reducing overall data processing complexity through focused analysis.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

In some examples, weld monitoring systems may use position tracking systems to track the positions, orientations, and/or movements of an (e.g., expert) operator performing a welding-type operation using a welding-type tool 106. An instruction generation process may then be used to automatically generate welding instructions based on the tracked positions, orientations, and/or movements. The welding instructions may be associated with a particular job, part, and/or welding position, and thereafter used to help guide future operators through similar welding-type operations when the future (e.g., less experienced operator) is working on a similar job/part and/or at a similar welding position.
