Hooded Sun Shield with Ventilated Mask and Glare Nose Piece
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sun protective clothing accessories, such as neck buffs, provide inadequate facial coverage, are restrictive, and fail to protect against reflective sun rays and extreme conditions like wind and high speeds, leading to discomfort and fogging of eyewear.
Innovation Solution
A hooded sun shield with a two-piece configuration, including a head piece with side ventilation and a detachable mask piece, along with a nose piece, designed to provide full facial protection, airflow, and reduce glare, using sun protective fabrics and adjustable fasteners to ensure comfort and secure fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a tight-fitting neck buff is used to protect the face, then sun protection coverage is improved, but breathing comfort deteriorates and eyewear fogging increases
Solution Approach 1:
The hooded sun shield is divided into multiple functional segments: a headpiece with side ventilation openings for airflow, a detachable mask piece with breathing holes for comfortable breathing, and a nose piece for glare protection. This segmentation allows each component to address specific needs while maintaining overall sun protection.
Solution Approach 2:
Different regions of the sun shield have different properties optimized for their specific functions: the headpiece has ventilation openings for air circulation, the mask piece has breathing holes for respiratory comfort, and the nose piece provides targeted glare protection. This local differentiation resolves the contradiction between coverage and comfort.
2Object-affected harmful factors
If a tight-fitting neck buff is used to protect the face, then sun protection coverage is improved, but temperature comfort deteriorates
Solution Approach 1:
The hooded sun shield divides the protective structure into segments with ventilation openings in the headpiece and breathing holes in the mask piece, creating channels for air circulation that prevent heat buildup while maintaining sun protection coverage.
Solution Approach 2:
The mask piece incorporates breathing holes that create a porous structure, allowing air to pass through and providing cooling effects that prevent temperature buildup while maintaining protective coverage.
3Object-affected harmful factors
If a tight-fitting neck buff is used to protect the face, then sun protection coverage is improved, but eyewear performance deteriorates due to fogging
Solution Approach 1:
The breathing holes in the mask piece extract moisture and warm air that would otherwise accumulate and cause fogging of eyewear. By removing these problematic elements through dedicated ventilation pathways, eyewear functionality is maintained while sun protection coverage is preserved.
4Device complexity
If a single-piece neck buff is used, then device simplicity is improved, but protection effectiveness deteriorates in extreme conditions
Solution Approach 1:
The hooded sun shield is divided into a headpiece, detachable mask piece, and nose piece, with each segment providing specific protective functions. This segmentation enhances protection effectiveness in extreme conditions while maintaining reasonable structural simplicity through modular design.
Solution Approach 2:
The hooded sun shield integrates multiple protective functions into a single system: sun protection, ventilation, breathing comfort, and glare protection. This multi-functionality addresses various extreme condition challenges while maintaining a unified wearable structure.
