Welding Headgear With Detachable Auxiliary Shield for Wider Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welding protectors often lack convenience in assembly, wearability, storage, and mobility due to their design limitations.
Innovation Solution
A welding protector design featuring a head band with a detachable auxiliary shield connected via a Velcro structure, providing improved protection and adjustability, including a face shield, head band, and auxiliary shield that covers additional head areas with materials resistant to heat and light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a welding protector includes only basic components (head band and face shield), then the device complexity is low, but the protection coverage and adaptability are insufficient
Solution Approach 1:
The welding protector is divided into separate functional modules: head band, face shield, and auxiliary shield. The auxiliary shield is detachably connected to the head band via Velcro, allowing independent assembly and disassembly. This segmentation enables enhanced protection coverage without permanently increasing device complexity.
Solution Approach 2:
The auxiliary shield serves multiple protective functions by covering additional areas (ears, temples, sides of head) that the basic face shield does not protect. This multi-functional component increases adaptability and versatility while maintaining a relatively simple overall structure.
2Ease of operation
If the auxiliary shield is permanently attached to the head band, then the assembly is more stable, but the ease of operation and storage convenience deteriorate
Solution Approach 1:
A Velcro connection element serves as an intermediary between the auxiliary shield and head band. This intermediary provides a detachable yet stable connection, allowing the user to easily attach and detach the auxiliary shield while maintaining reliable connection during use. The Velcro mechanism balances ease of operation with assembly stability.
3Object-affected harmful factors
If the auxiliary shield covers more areas of the head, then the protection effectiveness increases, but the weight and volume of the protector increase
Solution Approach 1:
The auxiliary shield provides localized protection specifically for areas not covered by the face shield (ears, temples, sides of head). Rather than uniformly increasing protection across the entire head, the auxiliary shield concentrates protective material only where additional protection is needed, minimizing unnecessary weight and volume increase.
