Welding Helmet Display Cartridge With AR Coating for Clear In-Mask Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welding operators face inconvenience as they cannot view relevant information during welding operations due to the design of conventional welding protectors, which lack an integrated display system, requiring them to remove the protector to access information.
Innovation Solution
A welding protector with a helmet unit, a mounting frame unit, and a cartridge unit that includes a filter portion, a panel portion, and an information display portion with an anti-reflection coating layer, allowing operators to view work information directly without removing the helmet, and adjustable to suit their viewing needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an information display portion is added to the welding protector, then the operator can view work information during welding operation, but the device complexity increases
Solution Approach 1:
The patent combines the information display portion with the existing welding protector structure by integrating it into the cartridge unit. The display is merged with the filter portion, panel portion, and glass portion that are already part of the welding protector assembly, thereby adding functionality without significantly increasing overall device complexity.
Solution Approach 2:
The cartridge unit serves multiple functions: it filters light during welding operations and simultaneously displays work information. By making the cartridge unit multi-functional, the patent avoids adding separate independent components, thus improving ease of operation while controlling device complexity.
2Illumination intensity
If an anti-reflection coating layer is applied to the information display portion, then diffuse reflection is minimized and clear vision is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies an anti-reflection coating layer to the information display portion to change the optical parameters of the surface. This coating modifies the refractive index and reduces diffuse reflection, thereby improving display clarity. The parameter change approach allows achieving clear vision while using standard coating technologies.
Solution Approach 2:
The information display portion uses a composite structure combining transparent material with an anti-reflection coating layer. This composite material approach optimizes both the display transparency and the anti-reflection properties, achieving clear vision without requiring extremely high manufacturing precision.
3Adaptability or versatility
If the mounting frame unit is made detachable and attachable, then the adaptability is improved, but the reliability of connection decreases
Solution Approach 1:
The mounting frame unit is designed with detachable and attachable characteristics, allowing it to transition between different connection states. This dynamic design enables the operator to adjust or remove the cartridge unit as needed, improving adaptability while maintaining sufficient connection reliability when attached.
