Unicoupon Welding Simulator with Magnetic Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual welding simulators require frequent repositioning or replacement of mock welding coupons to switch between different types of simulated welds, which is inconvenient and can lead to improper mounting, resulting in incorrect simulated welding data.
Innovation Solution
A mock welding unicoupon with multiple grooved surfaces and a curved exterior surface that can simulate various types of welds, including pipe fillet, vertical groove, horizontal groove, and flat groove welds, using a magnet source to track the movement of a mock welding tool and generate a magnetic field for spatial tracking, allowing for seamless switching between weld types without manual repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple physical models of weldments are used to simulate different types of welds, then the versatility of the welding simulator is improved, but the device complexity and ease of operation deteriorate due to the need to reposition or replace coupons
Solution Approach 1:
The mock welding coupon is designed with multiple grooves of different orientations (vertical, horizontal, angled) and a curved exterior surface that can simulate various types of welds including fillet welds, groove welds, and pipe welds. This multi-functional design allows a single coupon to replace multiple specialized coupons, enabling the simulator to handle different weld types without requiring physical replacement of the coupon.
2Adaptability or versatility
If mock welding coupons are repositioned or replaced to switch between weld types, then the versatility is improved, but the reliability deteriorates due to improper mounting
Solution Approach 1:
The magnet source is pre-positioned at a specific location on the mock welding coupon, and the virtual reality welding simulator is pre-programmed to recognize this fixed magnetic field position. This preliminary setup ensures that when the coupon is placed on the stand, the system automatically detects the correct position and orientation through the magnetic field, eliminating the need for manual positioning adjustments and ensuring reliable welding data collection from the start.
3Adaptability or versatility
If frequent repositioning of mock welding coupons is required, then the versatility is improved, but the loss of time increases due to training interruptions
Solution Approach 1:
The mock welding coupon integrates multiple groove configurations (vertical grooves for vertical groove welds, horizontal grooves for horizontal groove welds, angled grooves for angled welds, and a curved exterior surface for pipe welds) into a single physical object. This universal design allows welders to practice multiple weld types sequentially on the same coupon without interruption, as the virtual reality simulator can switch between simulating different weld types by referencing the known geometric characteristics of the grooves, thereby eliminating time-consuming physical repositioning operations.
