Eyeglass Structure With Segmented Flexible Temples
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglass temples made from titanium and plastic are prone to displacement and friction issues, leading to discomfort and potential skin damage due to their lightweight and flexible nature, which compromises adherence and stability.
Innovation Solution
The design features flexible plastic temples with distinct front and rear portions, where the rear portions have higher flexibility and friction for secure adherence to the ear, and the front portions are more rigid for stability and resilience against collisions, using materials like styrene-butadiene-styrene copolymer (SBS) to enhance comfort and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the temples are made lightweight and flexible using plastic and titanium, then the weight is reduced and comfort is improved, but the temples become easily displaced or detached due to lack of stability
Solution Approach 1:
The temple is divided into two distinct portions: a front portion connected to the main frame and a rear portion extending from the front portion. The front portion is designed with higher rigidity for stability, while the rear portion is designed with higher flexibility for comfort and adaptability. This segmentation allows each portion to fulfill its specific function optimally.
Solution Approach 2:
Different portions of the temple are assigned different mechanical properties. The front portion has preferred structural rigidity to prevent displacement and protect the eye portion, while the rear portion has excellent flexibility to adhere to the ear and absorb collision forces. This local differentiation of properties resolves the contradiction between overall stability and local adaptability.
2Adaptability or versatility
If the plastic layer is made thin to maintain flexibility, then the weight is reduced and flexibility is improved, but the temples cannot securely adhere to the ear portion leading to sliding and friction
Solution Approach 1:
The rear portion of the temple is designed with higher flexibility and friction to securely adhere to the ear portion. This local quality enhancement ensures that the temple can adapt to the contours of the ear while maintaining secure attachment, preventing sliding and friction-related discomfort.
Solution Approach 2:
The flexibility parameter is varied along the length of the temple. The rear portion has higher flexibility to conform to the ear, while the front portion has lower flexibility for stability. This parameter change allows the temple to achieve both adaptability and reliability in different regions.
3Weight of moving object
If the temples are made slim and light to reduce weight, then the overall weight is reduced, but the temples are easily displaced or detached due to movements of the user or external collisions
Solution Approach 1:
The temple structure is segmented into a front portion and a rear portion with different strength characteristics. The front portion is designed with higher strength and rigidity to resist collisions and protect the eye portion, while the rear portion maintains flexibility for comfort. This segmentation allows the temple to be overall lightweight while having localized strength where needed.
Solution Approach 2:
The rear portion of the temple is designed with high flexibility and friction to act as a buffer that absorbs collision forces before they can affect the front portion or the user's ear. This beforehand cushioning protects against external collisions while maintaining the lightweight design.
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
This configuration reduces sliding and irritation, provides adjustable fit, and effectively absorbs collision forces, enhancing overall comfort and protecting the eyeglasses from damage while maintaining secure wear.
Implementation Method 1
The rear portion of each of the flexible plastic temples is a flexible structure having high frictional force and adheres to the skin
Implementation Method 2
the rear portions which have excellent flexibility act as buffer for absorbing most of the colliding force

AI summary
The present disclosure provides an eyeglass structure having flexible temples, comprising: a main body; and two flexible plastic temples respective connected at two ends of the main body. The two flexible plastic temples each have a front portion proximal to the main body and a rear portion extending from the respective front portion. The degree of flexibility of the rear portions is greater than that of the front portions. The rear portions can be bent to from a support structure for the ear portion of a user. By this configuration the conformity and comfort of the eyeglass structure is improved.
