Glasses Leg Elastic Hinge for Foldable, Flexible Wearing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart glasses with a butterfly hinge at the joint of the glasses legs and the frame face issues of infirm wearing and low flexibility.
Innovation Solution
A connecting device comprising a first connecting member, a second connecting member, and an elastic member, where the first end of the second connecting member is hinged with the first connecting member, the second end is hinged with the glasses leg, and the elastic member is located between them, allowing the glasses leg to rotate away from the main body while being driven by the elastic member to clamp onto the wearer's head, improving flexibility and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a butterfly hinge is used at the joint of the glasses legs and the frame, then the glasses can be folded inward to reduce volume and facilitate storage, but the wearing firmness and flexibility are insufficient
Solution Approach 1:
The connecting device is divided into multiple components: a first connecting member on the frame, a second connecting member on the glasses leg, and an elastic member connecting them. This segmentation allows each component to perform a specific function - the hinge enables folding while the elastic member provides clamping force, collectively solving both volume reduction and wearing firmness requirements
Solution Approach 2:
The connecting device transitions from a static hinge to a dynamic mechanism where the elastic member can deform and recover. The glasses leg can rotate away from the main body and the elastic member drives it back, providing automatic adjustment and firm wearing without rigid constraints, thus improving both flexibility and reliability
2Volume of moving object
If a butterfly hinge is used at the joint of the glasses legs and the frame, then the glasses can be folded inward to reduce volume and facilitate storage, but the flexibility of the glasses is reduced
Solution Approach 1:
The elastic member introduces dynamic characteristics to the connecting device, allowing the glasses leg to rotate freely within a certain range and then be automatically returned to its original position. This provides flexibility for different wearing scenarios while maintaining compact storage capability
Solution Approach 2:
The elastic member changes the mechanical parameters of the connecting device by introducing elastic deformation and recovery. This allows the system to accommodate different head sizes and wearing positions, enhancing adaptability while maintaining the folded storage function
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 the wearing experience by providing firm fit and flexibility, allowing the glasses to adapt to different head sizes without additional specifications, reducing production and procurement costs.
Implementation Method 1
the elastic member is located between the second connecting member and the glasses leg, where a first elastic end of the elastic member abuts against the glasses leg, a second elastic end of the elastic member abuts against the second connecting member, and in a case that the glasses leg rotates away from the main body, the elastic member drives the glasses leg and the second connecting member to be away from each other
