Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable eyeglasses lack combination function, fashion, and style, making them unsuitable for meeting changing market demands and user preferences, particularly in terms of usability and safety.
Innovation Solution
An eyeglass bridge structure with angular and elastic folding capabilities is developed, utilizing a design with lateral portions, connectors, and a central piece that allows for angular folding and unfolding without elastic parts, featuring a square and elongate opening configuration and a circular hook mechanism for secure engagement, made from materials like monel, titanium, or beryllium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional foldable eyeglasses are designed to be small and flat when folded, then space-saving function is improved, but combination function, fashion, and style are deficient
Solution Approach 1:
The eyeglass bridge is designed with dynamic folding capabilities allowing multiple angular positions (fully folded, partially folded, and unfolded states). The bridge can be folded at angular positions between 0-180 degrees, enabling the glasses to adapt to different usage scenarios and styling preferences while maintaining a compact form when needed.
2Device complexity
If conventional foldable eyeglasses use simple folding mechanisms, then device complexity is reduced, but reliability and safety are compromised
Solution Approach 1:
The eyeglass bridge is segmented into multiple functional components: a first lateral portion, a second lateral portion, a central piece, and connectors with circular hooks. Each segment has specific engagement features (square openings, elongate openings, stoppers) that work together to provide reliable folding and unfolding motions while maintaining structural integrity.
Solution Approach 2:
The design incorporates stoppers on the connectors that engage with the central piece to limit the folding motion and prevent over-folding. This beforehand cushioning mechanism ensures the bridge folds to the desired angular position without compromising the structural integrity or safety of the eyeglasses.
3Ease of operation
If conventional foldable eyeglasses use elastic parts for folding motion, then ease of operation is improved, but device complexity and number of parts increase
Solution Approach 1:
The eyeglass bridge utilizes the inherent elastic properties of the material (monel, titanium, or beryllium) to provide the folding motion without requiring separate elastic parts. The bridge structure itself serves the dual function of providing both the structural framework and the elastic recovery force needed for folding and unfolding motions.
Solution Approach 2:
The design changes the physical parameters of the bridge structure, specifically the thickness distribution. The thickness between the inner surface and straight surface is made one-fifth larger than the thickness between the recessed surface and straight surface, creating built-in elastic zones that enable smooth folding motion through material deformation rather than separate elastic components.
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 solution enhances usability and safety by providing a reliable, space-efficient, and stylish foldable eyewear bridge structure that minimizes parts for folding and unfolding, offering improved angular and elastic motion while maintaining product reliability and safety.
Implementation Method 1
an upper end of the end wall of each of the first and second connectors serves to elastically slide on a lower end of each of the inner wall of the first and second lateral portions when the bridge structure is unfolded, and elastically release from the lower end of the inner wall of each of the first and second lateral portions when the bridge structure is folded
