Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional welding training systems lack the ability to simulate complex structures and provide realistic education, particularly when structures involve multiple pieces or require welds from various angles, and they do not facilitate training for robotic welding machinery.
Innovation Solution
A welding simulator and training system that uses a display, mock welding tool, and simulated workpieces with a database to generate a simulated environment, track weld paths, and display simulated welds, allowing for scoring and feedback, and can transfer data to robotic systems for actual weld execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional welding training systems use actual welding guns and sample workpieces, then students can learn real welding skills, but materials are consumed and safety risks increase
Solution Approach 1:
The patent creates a virtual copy of the welding environment, including virtual workpieces, welding guns, and welding processes. Students interact with these digital replicas instead of physical materials, eliminating consumption of welding rod/wire while maintaining training effectiveness through realistic simulation of welding dynamics and outcomes
Solution Approach 2:
The patent replaces the physical mechanical welding system with a computational simulation system. The welding process is modeled through software that simulates arc behavior, heat transfer, and weld pool dynamics, substituting physical material consumption with digital computation while preserving the educational value of learning real welding skills
2Reliability
If conventional welding training systems use actual welding guns and sample workpieces, then students can learn real welding skills, but safety risks from arc and sparks increase
Solution Approach 1:
The patent creates a virtual copy of the welding environment, including virtual workpieces, welding guns, and welding processes. Students interact with these digital replicas instead of physical materials, eliminating consumption of welding rod/wire while maintaining training effectiveness through realistic simulation of welding dynamics and outcomes
Solution Approach 2:
The patent introduces a computer-generated virtual environment as an intermediary between the student and the actual welding process. This virtual layer allows students to practice welding techniques and receive feedback on their performance without being exposed to the harmful effects of real welding arcs, sparks, and flash
3Ease of manufacture
If conventional welding training systems use simple sample workpieces, then training setup is simple, but complex structures and multiple angles cannot be simulated
Solution Approach 1:
The patent creates a universal virtual training environment that can accommodate any workpiece geometry or configuration. The software system allows instructors to import or design complex three-dimensional structures and configure multiple welding angles and positions digitally, enabling a single system to handle diverse training scenarios from simple joints to complex assemblies without requiring physical reconfiguration
Solution Approach 2:
The patent transitions from two-dimensional or simple three-dimensional physical sample workpieces to fully three-dimensional virtual structures with unlimited geometric complexity. The virtual environment allows workpieces to be oriented in any spatial configuration, enabling students to practice welding on complex structures with multiple angles and approaches that would be difficult or impossible to replicate with physical samples
4Reliability
If conventional welding training systems require instructors to guide students, then safety is monitored, but large numbers of sample workpieces are needed
Solution Approach 1:
The patent incorporates automated feedback mechanisms that monitor student performance in real-time and provide immediate guidance. The system tracks welding parameters, weld quality, and technique, offering corrective feedback without requiring instructor intervention. This automated monitoring eliminates the need for large quantities of consumable sample workpieces while maintaining safety supervision through software-based performance tracking and evaluation

AI summary
A welding simulator (100) which facilitates simulated welding training on a complex structure. The simulator may receive CAD or actual measurement data for components forming the structure and use the data to generate digital models of the components for display or analysis activities. The simulator (100) may enable simulated testing of the complex structure and calculate performance measures using the results of the simulated testing. The simulator (100) may allow a user (1202, 1204) to repeat a simulated weld until a desired score is achieved and store data collected during the simulated weld for later use.
