Spectacle Temple Elastic Member for Stable Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spectacles with non-elastic temples are prone to deformation, loosening, and falling off due to repeated outward pulling, leading to discomfort and instability when worn, and inability to securely fold inward when not in use.
Innovation Solution
Incorporating elastic members into the spectacle structure with pivoting parts, allowing temples to be elastically expanded outward for stable wear and firmly folded inward for secure storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If temples are made non-elastic and rigid, then manufacturing is simpler and structure is more stable, but temples deform and break when pulled outward during wear
Solution Approach 1:
The patent changes the physical parameter of the temple from rigid to elastic by incorporating an elastic member. This allows the temple to flex outward during wear without breaking, while maintaining structural integrity when folded inward. The elastic member transforms the temple from a static rigid component to a dynamic elastic component that can adapt to wear conditions.
2Ease of operation
If temples are pulled outward repeatedly for wear adjustment, then wearing comfort improves, but pivoting parts loosen and temples become unstable
Solution Approach 1:
The patent introduces dynamics to the temple system by adding an elastic member that allows controlled movement. The elastic member enables the temple to flex outward during wear while the pivoting part maintains its structural integrity through the elastic constraint, preventing loosening from repeated adjustments.
3Ease of operation
If temples are folded inward for storage, then portability improves, but temples randomly open outward and lose clamping function
Solution Approach 1:
The elastic member is pre-loaded in a compressed state when the temple is folded inward, creating a preliminary counteracting force that prevents the temple from randomly opening outward during storage. This stored elastic energy provides continuous resistance against unintended opening.
4Ease of manufacture
If pivoting parts are designed without elastic constraint, then manufacturing is simpler, but parts loosen after repeated use
Solution Approach 1:
The elastic member acts as an intermediary element between the pivoting part and the temple. It provides the necessary constraint to prevent loosening without requiring complex modifications to the pivoting part structure itself, maintaining manufacturing simplicity while improving reliability.

AI summary
The present invention provides a spectacle structure that includes a frame, two elastic members, and two temples, respectively, arranged thereon. The two elastic members are respectively assembled in the receiving grooves of two pivoting parts of the frame. The elastic member has a positioning end provided at one end thereof and snapped in an engaging groove of the frame, and a resisting end provided at the other end thereof and resisted to the temple. The temple has a pivoting lug provided at a front end thereof, and the front end surface of the pivoting lug is resisted by the resisting end of the elastic member when the temple is assembled in the pivoting part of the frame. Due to the elastic members between the temples and the frame, the temples can be unfolded elastically when worn, and the temples can be stably positioned when being unfolded or folded.
