Magnetic Insect Screen Assembly for Sunglasses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to effectively prevent insects and airborne particles from entering the nose, mouth, and ears of a wearer, particularly during outdoor activities like cycling, as they do not provide a comprehensive and secure screening mechanism for sunglasses.
Innovation Solution
An insect screen assembly with a magnetically attachable screen that covers the nose, mouth, and ears, featuring a flexible or rigid screen panel with multiple openings, supported by a frame and secured using magnets and adjustable straps for attachment to sunglasses and neck adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screen assembly is attached to sunglasses using magnets, then the screen can be easily attached and detached, but the attachment strength may be insufficient for active use
Solution Approach 1:
The attachment system is divided into multiple magnetic components: magnets in the sunglasses frame and corresponding magnets in the screen assembly. This segmentation allows independent optimization of each component while achieving reliable overall attachment through cumulative magnetic force across multiple contact points.
Solution Approach 2:
Multiple attachment mechanisms are combined: magnetic attachment provides easy on/off capability while elastic straps provide continuous securing force. The magnetic components and elastic straps work together to achieve both ease of operation and reliable attachment during active use.
2Object-affected harmful factors
If the screen assembly covers the nose, mouth, and ears, then protection against insects and particles is improved, but the device complexity increases
Solution Approach 1:
The screen assembly serves multiple protective functions simultaneously: it blocks insects and particles from entering the nose, mouth, and ears while also providing UV protection through integration with sunglasses. The elastic straps serve dual purposes of securing the screen assembly and providing a snug fit around the head.
Solution Approach 2:
The screen assembly uses a flexible mesh material that can conform to the contours of the face and accommodate the integrated sunglasses. This flexibility reduces the need for complex rigid framing while maintaining protective coverage over the nose, mouth, and ears.
3Ease of operation
If elastic straps are used to secure the screen assembly, then the fit can be adjusted for comfort, but the device complexity increases
Solution Approach 1:
The elastic straps allow dynamic adjustment of the screen assembly fit by changing the tension parameter. Users can adjust the strap length and tension to achieve optimal comfort and security for different head sizes and activity levels, transforming a fixed-fit device into an adaptable one.
Solution Approach 2:
The elastic straps provide a dynamic securing mechanism that adapts to movement and changing conditions during use. The elasticity allows the straps to maintain constant tension and secure fit regardless of head movement or sweating, replacing rigid fixed-position fastening systems.

Function Achieved in This Case
Effectively blocks flies, insects, and airborne particles, providing a secure and adjustable solution for wearers by magnetically attaching to sunglasses and adjustable straps for a snug fit, enhancing comfort and protection during outdoor activities.
Implementation Method 1
The pair of screen magnets may magnetically engage the pair of frame mount magnets, respectively, to detachably secure the assembly screen on the sunglasses
