Attachable Eyewear Side Panels for Sun Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional face shields obstruct vision and cause fogging and discomfort while providing unnecessary protection, especially for drivers who need to focus on the road without covering the nose and mouth, and they do not effectively protect sideburns and cheeks from sun exposure.
Innovation Solution
Attachable, detachable, and retractable side panels connected to eyewear shafts via adjusting clips, allowing for customizable protection of sideburns and cheeks while keeping the nose, mouth, and eyes uncovered, using a mechanism with stoppers, a wheel, and magnetic snap fasteners for secure and easy extension and retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional face shields are used to protect the entire face, then protection against solar rays is improved, but vision obstruction and fogging increase
Solution Approach 1:
The face shield is divided into separate zones: clear zones around the eyes and mouth, and protected zones covering the cheeks and sideburns. This segmentation allows selective protection of sun-exposed areas while maintaining visual clarity and breathability zones.
Solution Approach 2:
Different regions of the face shield have different optical properties. The cheek and sideburn protection areas use sun-blocking material, while the eye and mouth areas remain transparent or open, creating local quality variations that address different functional requirements simultaneously.
2Object-affected harmful factors
If the entire face is covered with a face shield, then sun protection is improved, but breathing comfort deteriorates due to fogging
Solution Approach 1:
The face shield design segments the breathing zones (mouth and nose areas) from the sun protection zones (cheeks and sideburns), creating open or clear pathways for breath flow that prevent fogging while maintaining sun blockage where needed.
Solution Approach 2:
The mouth and nose breathing areas are extracted from the sun-blocking coverage, creating designated open zones that allow unrestricted breath flow and prevent the accumulation of water vapor that causes fogging.
3Reliability
If permanent modifications are made to eyewear shafts to attach face shields, then attachment reliability is improved, but ease of manufacture and adaptability deteriorate
Solution Approach 1:
The attachment system transitions from permanent fixed attachment to a dynamic, adjustable system where panels can be attached, detached, and repositioned. The shafts include adjustable features that allow reliable attachment without permanent modification, enabling flexibility in configuration.
Solution Approach 2:
The eyewear shafts are designed with universal attachment features that can accommodate different panel configurations and types. The adjustable clips and mounting mechanisms provide multi-functional capability for securing various shield arrangements without requiring specific permanent modifications.
