Welding Helmet Display Recess for Protected Peripheral Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing welding helmets with display devices are prone to environmental influences such as dust, sweat, and mechanical loads, leading to reduced service life and obstructed vision, and often fail to account for ametropia, while being complex and costly.
Innovation Solution
The display device is positioned in the edge region of the welder's field of vision between the anti-glare device and the protective screen, with an optional recess in the anti-glare device to minimize obstruction, and can be adjusted for optimal viewing, using a seal for protection and connected to a control device for data transmission, allowing for adjustable and replaceable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display device is integrated into the welding helmet to show welding parameters, then the welder can monitor data without taking eyes off the weld, but the display device becomes exposed to dust, fumes, and mechanical stress
Solution Approach 1:
The display device is nested within the protective lens housing, positioned in the space between the protective lens and the glare protection device. This nesting arrangement allows the display to be protected by the protective lens while remaining visible to the welder, solving both the information visibility and protection requirements simultaneously
2Object-affected harmful factors
If the glare protection device is made dark to protect eyes from welding arc, then eye protection is improved, but the view of displayed data becomes obstructed
Solution Approach 1:
The glare protection device is designed with a recess or cutout in the specific area where the display device is located. This local modification allows light to pass through to the display while the rest of the glare protection device remains dark to protect the welder's eyes, thus maintaining both eye protection and display visibility
Solution Approach 2:
The display area is extracted or removed from the darkened glare protection device, creating a separate viewing zone. This allows the display to be visible while the surrounding glare protection remains intact, solving the contradiction between eye protection and display visibility
3Ease of operation
If the display device is positioned centrally in the field of vision, then data is easily readable, but the welder's view of the weld seam is obstructed
Solution Approach 1:
The display device is positioned in the peripheral area of the field of vision rather than centrally, utilizing the lateral dimension of visual space. This allows the welder to perceive display information without the display physically blocking the central view of the weld seam, effectively using spatial dimensionality to resolve the contradiction

AI summary
The invention relates to a welding helmet (1) having at least one helmet shell (2), fastening elements (3), a glare shield device (4) and at least one protective screen (5) spaced therefrom, and at least one display device (6) for presenting data in the field of view of a welder, the at least one display device (6) being arranged in the edge region of the field of view in the intermediate space (8) between the glare shield device (4) and the protective screen (5). To achieve a particularly simple and cost-effective variant of a welding helmet (1), the glare shield device (4) has at least one cut-out (12) in the region of the at least one display device (6). Because there is no glare shield device (4) in the region of the display device (6), the view of the display device (6) is not impeded by the glare shield device (4).
