Welding Mask Imaging for Arc Glare and Surrounding Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welding operators face difficulties in recognizing surrounding environments and obtaining accurate welding information due to the high brightness of welding lights, which limits their ability to perform precise welding operations, especially when using automatic or manual welding masks.
Innovation Solution
A welding information providing apparatus with a camera unit, image generating unit, display unit, and processor that captures and processes welding images, providing high-definition composite images and real-time feedback to the user, while a battery-powered design eliminates the need for a wired connection to a power source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wired power source is used to supply power to the welding mask, then the device can operate continuously, but the user's movement is restricted and convenience is reduced
Solution Approach 1:
The patent extracts the power source from the external wired connection and places it within the welding mask itself through a battery pack. This allows the mask to operate independently without being tethered to an external power source, significantly improving user mobility and convenience while eliminating the complexity of external wiring.
Solution Approach 2:
The welding mask becomes self-sufficient by incorporating an internal battery pack that supplies power to all its components (camera, display, processor). The system serves itself by generating and storing the energy it needs, eliminating dependence on external power sources and wired connections.
2Object-affected harmful factors
If a darkening filter is used to protect eyes from welding light, then eye protection is improved, but visibility of surrounding environment deteriorates
Solution Approach 1:
The patent introduces a camera as an intermediary device that captures the surrounding environment and transmits it to a display. This mediator allows the user to see around the darkening filter's obstruction, providing environmental information that would otherwise be lost due to the necessary eye protection.
Solution Approach 2:
The camera creates a visual copy of the surrounding environment and displays it to the user. This copy compensates for the information blocked by the darkening filter, allowing the user to perceive the workspace layout and conditions without removing eye protection.
