Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional welding training systems are used, then training effectiveness is limited, but acquisition and operation costs are high

Engineering Contradiction:
Improvetraining effectivenessVSAvoidsystem cost
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses virtual reality to create a virtual copy of the welding environment, allowing trainees to practice welding techniques in a simulated setting. This virtual welding system replicates the visual and operational aspects of real welding without requiring expensive physical training equipment, thereby reducing costs while maintaining training effectiveness

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces physical welding training equipment with a computational system that uses cameras, processors, and software to simulate welding operations. The mechanical welding training apparatus is substituted with digital image processing and virtual reality technologies, reducing hardware costs while providing comprehensive training feedback

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

2Productivity

If more welding training systems are acquired, then training capacity increases, but operational costs increase

Engineering Contradiction:
Improvetraining capacityVSAvoidoperational cost
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The welding training system is designed to be universally applicable across multiple trainees and different welding scenarios. A single system can serve multiple students sequentially, and the virtual reality environment can simulate various welding positions and techniques, eliminating the need to acquire separate physical training systems for each student or welding type

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

Solution Approach 2:

The system provides automated feedback and evaluation through image processing algorithms that automatically analyze welding quality metrics. This self-evaluating capability eliminates the need for additional instructors or manual assessment processes, reducing operational costs while maintaining high training capacity

Inventive Principle:
Principle #25Self-service

3Measurement precision

If manual welding assessment is used, then feedback is provided, but measurement precision is insufficient

Engineering Contradiction:
Improveweld quality assessment accuracyVSAvoidassessment system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual visual inspection with automated image processing systems that use cameras and computer algorithms to measure welding parameters. The system objectively quantifies weld bead geometry, penetration, and other quality metrics with high precision, eliminating the subjectivity and limitations of human assessment

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

Solution Approach 2:

The patent introduces an intermediate image processing layer between the welding operation and the assessment result. Cameras capture images of the welding process, software algorithms process these images to extract quantitative measurements, and this intermediate computational step enables precise objective assessment without requiring direct manual measurement

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method of operating a welding system includes receiving welding data corresponding to a welding session for a weld, receiving a location selection from an operator, and displaying on a display a graphical representation of welding parameters of the welding selection corresponding to the location selection. The welding data includes welding parameters, including a work angle of a welding torch, a travel angle of the welding torch, a contact tip to work distance, a travel speed of the welding torch along a path of the weld, an aim of the welding torch, or any combination thereof. The location selection corresponds to a point along the path of the weld traversed by the welding torch.
