Foldable Auxiliary Shield Structure for Compact Welding Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Protectors for welders are difficult to store and transport due to their complex structures and components, which can lead to damage and reduced durability.
Innovation Solution
A welding protector design featuring a face shield with an auxiliary shield that includes multiple overlapping portions, which can be folded or rotated to reduce overlapping area, allowing for compact storage and increased portability, and is made of durable materials like metal or heat-resistant plastic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the auxiliary shield includes multiple overlapping portions for comprehensive protection, then the protection coverage is improved, but the device complexity and storability deteriorate
Solution Approach 1:
The auxiliary shield is divided into multiple overlapping portions that can be separately positioned and adjusted. Each portion can be independently folded or rotated, allowing comprehensive protection coverage while maintaining the ability to compact the structure for storage by folding the segments together.
2Strength
If the auxiliary shield is made of hard material for durability, then the strength is improved, but the ease of storage and portability deteriorate
Solution Approach 1:
The auxiliary shield incorporates movable connections between portions that allow it to transition between extended and folded states. The hard material maintains durability when deployed, while the dynamic folding capability enables compact storage and improved portability when not in use.
3Object-affected harmful factors
If the auxiliary shield portions overlap extensively for protection, then the protection coverage is improved, but the storability deteriorates
Solution Approach 1:
The auxiliary shield portions are designed to nest within each other when folded, similar to nested dolls. The overlapping portions can be stacked and contained within a compact configuration, significantly reducing storage volume while maintaining the ability to provide comprehensive protection when deployed.

AI summary
Provided is a welding protector which includes a face shield configured to protect a face of a welder and an auxiliary shield disposed adjacent to one edge of the face shield. The auxiliary shield includes a plurality of portions which overlap each other in a first mode and move to reduce an overlapping area when switching from the first mode to a second mode.
