Pivoting Welding Visor With Flexible Bib for Head Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eye-protection headgear designs for high-intensity light environments, such as welding, often restrict the user's ability to tilt their head forward due to the rigid structure of conventional welding helmets, which can limit visibility and comfort.
Innovation Solution
The design incorporates a pivotably connected rigid visor with an optical filter, a flexible fabric bib, and a flexible fabric cap. The visor is movable between shielding and non-shielding positions, allowing the user to pivot the visor upward and maintain eye protection while allowing unobstructed vision in the forward direction without needing to manipulate the bib.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid welding helmet structure is used to provide eye protection, then eye protection reliability is improved, but head mobility and visibility are worsened
Solution Approach 1:
The welding helmet is divided into separate functional components: a rigid visor assembly for eye protection and a flexible bib for neck protection. The visor can be independently pivoted and removed, allowing head mobility while maintaining eye protection capability when needed.
Solution Approach 2:
The visor assembly is designed with pivotable connections allowing dynamic movement between different positions (shielding and non-shielding). This dynamic design enables the user to adjust the visor angle and remove it completely, providing both protection and mobility as needed.
2Stability of the object's composition
If a rigid visor structure is used to maintain protective positioning, then eye protection stability is improved, but adaptability to different working positions is worsened
Solution Approach 1:
The visor is connected via pivotable joints that allow adjustment to multiple angles and positions. The user can position the visor to provide protection while maintaining a comfortable working posture, and the visor can be quickly repositioned or removed to adapt to different task requirements.
Solution Approach 2:
The visor assembly serves multiple functions: it can be positioned to provide full face protection, adjusted to partial coverage for better visibility, or completely removed for unrestricted head movement. This multi-functional design adapts to various welding positions and tasks.
3Reliability
If the visor is fixed in position to ensure continuous protection, then eye protection reliability is improved, but ease of operation is worsened
Solution Approach 1:
The pivotable connection mechanism allows the visor to move smoothly between fixed protective positions and a removed state. The design provides stable protection when needed while enabling easy head movement when the visor is pivoted away or removed, combining reliability with operational ease.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances user comfort and visibility by allowing the visor to be easily moved into a non-shielding position, enabling the user to tilt their head forward without compromising eye protection, thus improving usability in tight or confined spaces.
