AI Welding Shield Display for Wider Arc-Safe Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional welding shields with auto-darkening filters limit the welder's field of view, causing eye fatigue and requiring manual control through mouth pressure, making it difficult to estimate the end of a welding line without interrupting the process.
Innovation Solution
A head-mounted welding shield equipped with digital video cameras, a processor, and a display that uses artificial intelligence and pattern recognition algorithms to detect welding arcs, adjusting the image to maintain uniform brightness and reduce arc intensity without affecting surrounding visibility, eliminating the need for manual filter control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an auto-darkening light filter is used to protect the welder from dazzle, then the welder's eyes are protected from intense arc light, but the field of view is limited and only a small area around the arc remains visible
Solution Approach 1:
A camera system acts as an intermediary between the welding arc and the welder's eyes. The camera captures the welding zone and transmits the image to a display, allowing the welder to see beyond the limited field of view of the auto-darkening filter while maintaining eye protection.
Solution Approach 2:
The solution transitions from direct optical viewing through the filter to electronic image transmission on a display screen. This dimensional shift from optical path to electronic display enables a wider field of view while maintaining the protective darkening function.
2Object-affected harmful factors
If the light filter enters shade mode to protect from arc light, then the welder is protected from dazzle, but the welder cannot see the surrounding area and must rely on visual memory or interrupt welding
Solution Approach 1:
The camera system serves as an intermediary that captures and transmits visual information about the surrounding welding area to the display, preventing information loss while the filter maintains its protective shade mode.
Solution Approach 2:
The electronic display provides continuous visual feedback about the welding progress and surrounding area, eliminating the need to interrupt welding to check progress and maintaining continuous visibility of the work area.
3Object-affected harmful factors
If the light filter darkens the surrounding area to protect from arc light, then the welder is protected from dazzle, but this leads to increased eye fatigue due to unnatural viewing conditions
Solution Approach 1:
By transitioning from direct optical viewing to electronic display, the system allows the filter to maintain its protective darkening function while the display presents the image in comfortable brightness conditions, separating the protection function from the viewing comfort function.
