X-Shaped Visor Support Assembly for Face Shield Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical protective face shields are uncomfortable to wear, difficult to install or replace, suffer from low air circulation leading to fogging, are heavier than necessary, and lack convenient storage solutions.
Innovation Solution
A lightweight protective face shield with a support assembly that interfaces with the head, featuring a visor that can be easily mounted and removed, improved air circulation, and a storage base with hooks for hanging, allowing for customizable fit and easy storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If known medical protective face shields are designed with dense coverage, then protection is improved, but air circulation is reduced causing fogging
Solution Approach 1:
The visor is divided into multiple panels separated by vertical bars that create airflow channels. This segmentation allows protection coverage while maintaining air circulation paths that prevent fogging by allowing air to flow through the structure.
Solution Approach 2:
The visor design incorporates different structural characteristics in different regions - the panels provide protection where needed while the vertical bars and spacing between panels create airflow zones. This local differentiation allows simultaneous achievement of protection and ventilation.
2Reliability
If known protective face shields use traditional mounting methods, then protection is provided, but installation and replacement become difficult
Solution Approach 1:
The mounting system uses elastic arms with spring mechanisms that provide dynamic adjustment and automatic engagement. The elastic arms can be compressed for installation and automatically lock into position, while also allowing easy release by applying force to the release mechanism, making both installation and replacement simple operations.
Solution Approach 2:
The elastic arms serve as intermediary components between the visor and the headgear. These intermediaries absorb the mechanical stress of installation and removal, providing a cushioning effect that makes the process easier while ensuring secure attachment during use.
3Reliability
If known protective face shields are designed for security, then protection is improved, but comfort is reduced due to weight
Solution Approach 1:
The face shield incorporates composite material construction using lightweight polymers and materials with high strength-to-weight ratios. This allows the structure to maintain necessary protection and security while significantly reducing the overall weight compared to traditional metal constructions.
Solution Approach 2:
The visor and protective elements are constructed using thin-walled but structurally sound shell designs that provide adequate protection with minimal material usage. This reduces weight while maintaining the necessary protective function through optimized geometric shapes and wall thicknesses.

AI summary
A new design protective face shield is described. The protective face shield includes a support assembly characterized in having an X-shaped portion at the front providing a clearance between the forehead of the wearer and the visor to be mounted thereto. The support assembly comprises protrusions designed to mount a top piece, a rear piece, and the visor, each comprising apertures adapted to cooperate with the protrusions to be mounted thereto. According to an aspect, the protective face shield includes a rotatable visor assembly adapted for being moved between a raised position and a lowered position. The protective face shield may be stored on a described base and may be complemented with accessories through use of a bracket.
