Wearable Welding Vision System for Arc Glare and Site Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welding processes pose challenges due to high-brightness/high-illuminance lights, making it difficult for users to visualize the welding site and surrounding environment, especially when wearing protective gear, which can lead to inaccurate welding and reduced visibility.
Innovation Solution
A welding information providing apparatus equipped with a camera unit featuring multiple cameras that image the welding site before, during, and after welding, with a light blocking cartridge and video processing to generate high-definition images, allowing users to view the site without removing protective gear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a blackening filter is used to protect the user's eyes from welding light, then the user's eyes are protected from intense light, but regions other than the welding light spot become completely invisible
Solution Approach 1:
The system divides the imaging function into multiple cameras: a first camera for capturing the welding light spot area and a second camera for capturing the surrounding environment. This segmentation allows simultaneous protection from welding light while maintaining visibility of the surrounding area through the second camera's feed displayed on the display unit.
Solution Approach 2:
The display unit acts as an intermediary, showing processed images from both cameras to the user. This allows the user to view the surrounding environment captured by the second camera while the first camera captures the welding area, effectively mediating between the need for eye protection and environmental visibility.
2Object-affected harmful factors
If users wear protective gear during welding, then the user's eyes are protected from light and heat, but users cannot conveniently check welding information and surrounding environment
Solution Approach 1:
The welding information providing apparatus integrates multiple functions into a single wearable system: the first camera captures welding light spot information, the second camera captures surrounding environment, the video generating unit processes and combines these feeds, and the display unit presents integrated visual information to the user. This multi-functional integration allows users to check both welding information and surrounding environment while wearing protective gear.
3Loss of information
If multiple cameras are used to image the welding site, then comprehensive visual information is provided, but device complexity increases
Solution Approach 1:
The video generating unit merges the video feeds from the first and second cameras into a single integrated display output. This combining approach provides comprehensive visual information from both cameras while presenting it through a unified interface, reducing the perceived complexity for the user despite using multiple cameras.
