Eyeglass Nose Support with Reversible Flexing Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nose supports for eyeglasses often fail to provide adequate comfort and secure fitting due to rigid designs that do not adjust to varying nose shapes and sizes, potentially pinching the nostrils and causing discomfort.
Innovation Solution
A nose support with a flexing section that is reversibly deflectable between an unflexed and a flexed state, comprising a soft resilient organic polymeric shell and elongate ribs with a gap, allowing for adjustment to different nose shapes and sizes, thereby enhancing comfort and secure fitting without excessive pinching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid nose supports are used, then structural strength is maintained, but comfort and adaptability to different nose shapes deteriorate
Solution Approach 1:
The nose support is divided into multiple sections including rigid portions and flexible portions. The rigid portions maintain structural strength while the flexible portions adapt to different nose shapes. This segmentation allows different regions of the nose support to perform different functions simultaneously.
Solution Approach 2:
The nose support incorporates flexible portions that can dynamically adjust to the wearer's nose shape. These flexible sections allow the nose support to change its configuration to accommodate varying nose geometries while maintaining overall structural integrity through the rigid portions.
2Ease of manufacture
If rigid nose supports are used, then manufacturing simplicity is maintained, but comfort and secure fitting without pinching deteriorate
Solution Approach 1:
The nose support is segmented into rigid and flexible portions that can be manufactured separately and then assembled. This approach maintains manufacturing simplicity for each component while achieving the complex function of comfortable and secure fitting through the combination of different material properties.
Solution Approach 2:
The nose support uses composite construction with rigid portions made from stronger materials and flexible portions made from more compliant materials. This composite approach enables secure fitting without pinching by distributing forces appropriately across different material zones.
3Adaptability or versatility
If flexible nose supports are used, then adaptability to nose shapes is improved, but structural strength and stability deteriorate
Solution Approach 1:
The nose support is segmented into rigid portions that provide structural stability and flexible portions that provide adaptability. The rigid portions maintain the overall shape and structural integrity while the flexible portions conform to the wearer's nose, achieving both stability and adaptability simultaneously.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The flexible design allows the nose supports to adjust to various nose shapes, providing enhanced comfort and secure fitting of eyeglasses without pinching the nostrils, ensuring the eyeglasses remain securely in place.

AI summary
A nose support for a pair of eyeglasses is disclosed. The nose support comprises an elongate main body comprising a flexing section which is reversibly deflectable between an unflexed state and a flexed state at a proximal end of the main body, a contact section at a distal end of the main body and a soft resilient organic polymeric shell which encases the main body.
