Visor Snap Fastener Attachment with Stop Component
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visors for protecting against droplet infections are often cumbersome and fail to provide reliable, variable attachment to the wearer, leading to discomfort and inefficiency, especially when used in activities like forestry, gardening, or construction.
Innovation Solution
A visor designed for attachment to a cap or headband using snap fasteners with push-button components and stop components, allowing for pivoting into various positions while preventing unintentional downward movement, and optionally incorporating elastic bands and ventilation slots for enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the visor is attached directly to the wearer's head, then protection against droplet infections is provided, but the attachment is not reliable and cannot be adjusted to different headgear types
Solution Approach 1:
The visor attachment system is divided into separate snap fastener components that can independently connect to different headgear types. Each snap fastener acts as an independent attachment unit, allowing the visor to be reliably connected to caps, headbands, or braces without requiring a custom integration for each headgear type.
Solution Approach 2:
The snap fastener components are designed with universal compatibility to work with multiple types of headgear (caps, headbands, braces). The same snap fastener mechanism can attach the visor to different headgear types, providing both reliable attachment and adaptability across various wear scenarios.
2Illumination intensity
If the visor is made of transparent plastic for protection, then visibility is maintained, but the visor becomes cumbersome and strenuous to wear
Solution Approach 1:
The visor design extracts the protective function from a full face mask, providing only the necessary facial protection through a transparent visor plate. This selective approach maintains visibility while eliminating the cumbersome requirements of full face masks, making the device easier to wear during manual activities.
Solution Approach 2:
The visor utilizes a thin, transparent plastic plate that provides protection without the bulk and discomfort of thicker mask structures. The flexible, thin-material construction allows for ease of wearing while maintaining the necessary protective function and visual clarity.
3Adaptability or versatility
If the visor is attached with snap fasteners in corner regions, then the visor can pivot to various positions, but the visor may unintentionally pivot downwards and expose the wearer's face
Solution Approach 1:
The stop component is positioned in advance to prevent the visor from pivoting downwards beyond a safe angle. This preliminary anti-action counteracts the potential harmful effect of unintentional downward pivoting, ensuring the visor remains in a protective position while still allowing intentional adjustment to various working positions.
Solution Approach 2:
The visor attachment system provides dynamic positioning capability through the snap fastener mechanism, allowing the visor to be adjusted between different working positions. The stop component introduces a dynamic constraint that prevents excessive downward pivoting while maintaining the flexibility to reach appropriate working angles.
4Weight of moving object
If the visor is designed without a rim, then the visor becomes lighter and more comfortable, but the attachment structure becomes more complex
Solution Approach 1:
The visor design removes the traditional rim structure, extracting this component to reduce weight and improve comfort. The attachment function is redistributed to discrete snap fastener components that can be integrated into the visor body without requiring a supporting rim structure.
Solution Approach 2:
The attachment structure is segmented into separate snap fastener components rather than a continuous rim structure. This segmentation allows the attachment function to be distributed across multiple discrete points, reducing the overall structural complexity and weight while maintaining secure attachment capability.
