Glasses Hinge Assembly With Elastic Clamping for Secure Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart glasses with butterfly hinges suffer from infirm wearing and low flexibility.
Innovation Solution
A connecting device with a first and second connecting member and an elastic member is used to hinge the glasses leg to the main body, allowing the elastic member to drive the glasses leg to clamp onto the head, enhancing flexibility and firm wearing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a butterfly hinge is used to fold the glasses leg inward, then the volume is reduced and storage is facilitated, but the wearing firmness deteriorates and flexibility is reduced
Solution Approach 1:
The connecting device is divided into multiple components: a first connecting member fixed to the main body, a second connecting member hinged to the glasses leg, and an elastic member connecting them. This segmentation allows the glasses leg to be folded inward for compact storage while the elastic member maintains continuous connection and provides automatic clamping force for firm wearing.
Solution Approach 2:
The connecting device incorporates a hinge joint between the first and second connecting members, enabling dynamic folding motion. The elastic member provides dynamic clamping force that automatically adjusts to secure the glasses leg to the wearer's head, transforming the static butterfly hinge into a dynamic system that adapts to wearing conditions.
2Volume of moving object
If a butterfly hinge is used to fold the glasses leg inward, then the volume is reduced and storage is facilitated, but the flexibility deteriorates
Solution Approach 1:
By segmenting the connecting device into multiple hinged components connected by an elastic member, the system achieves both compact folding capability and flexible adaptation to different head shapes and sizes, resolving the contradiction between volume reduction and flexibility.
Solution Approach 2:
The elastic member changes its physical state and dimensions dynamically during the folding and clamping process, allowing the glasses leg to adapt to different wearing conditions while maintaining a compact form when not in use.
3Reliability
If the glasses leg is made to automatically clamp onto the head, then the wearing firmness is improved, but the device complexity increases
Solution Approach 1:
The elastic member provides self-service functionality by automatically generating clamping force when the glasses leg is folded onto the head, eliminating the need for additional motors, sensors, or control systems. The elastic member's inherent physical properties enable the automatic clamping action, achieving reliable wearing firmness without significantly increasing device complexity.

AI summary
Disclosed in the present application are glasses, comprising a main body, temples and connecting devices. The temples are connected to the end of the main body by means of the connecting devices, such that the temples can rotate; the connecting devices comprise first connecting members, second connecting members and elastic members; the first connecting members are arranged at the end of the main body; first ends of the second connecting members are hinged to the first connecting members, and second ends of the second connecting members are hinged to the temples; the elastic members are located between the second connecting members and the temples; and first elastic ends of the elastic members abut against the temples, and second elastic ends of the elastic members abut against the second connecting members. Under the condition that the temples rotate far away from the main body, the elastic members drive the temples and the second connecting members to be far away from each other.
