Virtual Welding Rod Shortening for Realistic VR Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional welding systems require large-scale apparatus configurations and face challenges in imitating the effect of shortening a welding rod in virtual space when using a VR controller.
Innovation Solution
A welding training system that determines the distance between a welding rod tip and a parent material object, performs welding processing when the distance is within a threshold, corrects the welding rod length, and moves a dot object to the tip to imitate the rod shortening effect in virtual space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a real welding tool is used for welding operation training, then the training realism is improved, but the apparatus configuration becomes large-scale and complex
Solution Approach 1:
The patent uses a welding rod object that copies the essential characteristics and appearance of a real welding rod, allowing trainees to practice with a simplified virtual representation rather than requiring complex real welding equipment. This copying approach maintains training effectiveness while reducing system complexity
Solution Approach 2:
The patent replaces the mechanical welding tool system with a virtual welding rod object in a virtual space. The welding operation is simulated through computer graphics and coordinate transformations rather than requiring actual welding machinery, thus substituting a complex mechanical system with a software-based solution
2Ease of operation
If a VR controller is used instead of a special welding tool, then the ease of operation is improved, but the ability to imitate welding rod shortening effect deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of the welding rod object's length based on welding progress. The rod length is continuously modified through coordinate transformations as the welding operation progresses, allowing the virtual rod to dynamically shorten and consume just like a real welding rod, thereby maintaining training realism while using standard VR controllers
Solution Approach 2:
The patent changes the length parameter of the welding rod object during the welding operation. By modifying the axial length coordinate of the rod's tip based on welding distance and consumption, the system realistically simulates rod shortening without requiring special hardware, thus maintaining reliability while improving ease of operation

AI summary
An information processing apparatus (1) includes a distance determination unit (13) configured to determine a distance between a tip of a welding rod object used for a welding operation and a parent material object based on a distance between the parent material object and a dot object used for distance determination, the dot object being located at the tip, a welding processing performing unit (14) configured to perform welding processing in virtual space based on the determined distance, a welding rod length corrector (15) configured to perform a correction such that an axial length of the welding rod object is shortened, a distance determination object mover (17) configured to move the dot object to the tip of the welding rod object after the correction, and a display controller (19) configured to cause a display to display an image including the corrected welding rod object and the dot object moved.
