Welding Helmet Face Cover Mechanism for Soft Close and Reduced Strain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional welding helmets with moveable face covers are cumbersome and pose ergonomic issues due to their weight and manual operation, leading to neck strains and health risks during extended use.
Innovation Solution
Incorporation of a spring-assisted movement mechanism with rotational dampers to facilitate smooth opening and closing of the face cover, reducing manual effort and strain by using a track component, movement pin, and damping springs for a soft close.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a moveable face cover is added to the welding helmet, then the operator can see the surrounding environment, but the helmet becomes cumbersome and causes neck strains
Solution Approach 1:
The patent applies the anti-weight principle by using spring mechanisms to counterbalance the weight of the moveable face cover. The springs are positioned to provide upward force that offsets the gravitational pull on the face cover, making it easier to lift and position without straining the operator's neck and head muscles.
Solution Approach 2:
The patent implements dynamics by making the face cover moveable rather than fixed, allowing it to be positioned in different states (open, closed, intermediate). The spring mechanism enables dynamic adjustment of the face cover position, adapting to the operator's needs while reducing the static weight burden on the head.
2Ease of operation
If the face cover is made moveable for ease of use, then the operator can open and close it, but it requires manual effort and constant adjustment
Solution Approach 1:
The spring mechanism acts as a counterweight system that stores potential energy when compressed or extended. As the face cover moves, the spring releases or absorbs energy to assist the motion, significantly reducing the manual effort required to open and close the face cover repeatedly.
Solution Approach 2:
The spring mechanism provides self-service by automatically assisting the face cover movement without requiring external energy input from the operator. The spring's elastic properties enable it to self-regulate the force assistance throughout the range of motion, making the system self-sufficient.
3Ease of operation
If a spring-assisted mechanism is added to reduce manual effort, then ease of operation improves, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the movement mechanism into distinct functional components: the spring element, the mounting structure, and the connection points. This modular segmentation allows for easier manufacturing, assembly, and maintenance while achieving the desired ease of operation.
Solution Approach 2:
The spring acts as an intermediary element between the fixed helmet structure and the moveable face cover. It mediates the force transmission, providing mechanical assistance while isolating the complexity of the spring mechanism from both the helmet shell and the face cover, simplifying the overall system integration.

AI summary
Systems and methods are provided for welding-type headwear with enhanced movement and soft close. An example welding-type headwear has a moveable face cover configured for moving between a first position and an second position, and a movement mechanism configured for facilitating and controlling movement of the moveable face cover. The movement mechanism has a track component, a movement pin, and one or more springs. A movement assisting spring of the one or more springs is configured to assist in the moving of the moveable face cover towards to the second position. The track component has one or more tracks, and at least a portion of the movement pin is configured to move within the one or more tracks.
