Hyperextending Eyewear Hinge With Spring-Biased Temple Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyewear devices, such as smart glasses, face challenges in providing a comfortable and stable fit due to limitations in temple extension mechanisms, which affect usability and user experience.
Innovation Solution
Incorporation of a hyperextendable temple mechanism using a hinge assembly with an extender and a spring bias system that allows temples to hyperextend, providing a secure fit and enhanced comfort by urging the temples against the user's head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional hinge mechanisms are used in eyewear devices, then the structure remains simple and manufacturing is easier, but the temple extension capability is limited and cannot accommodate various head sizes
Solution Approach 1:
The temple incorporates a telescopic mechanism with nested segments that can extend and retract, allowing the temple to adjust its length to accommodate different head sizes while maintaining a compact form when retracted
Solution Approach 2:
The hinge mechanism transitions from a static connection to a dynamic system with multiple degrees of freedom, including rotational movement and telescopic extension, enabling the temple to adapt to various wearing conditions
2Adaptability or versatility
If the temple is made longer to fit larger heads, then adaptability improves, but the stability and secure fit deteriorate
Solution Approach 1:
The spring mechanism dynamically adjusts the extension parameter of the temple based on the applied force from the user's head, providing optimal fit stability at different extension lengths
Solution Approach 2:
The spring bias force acts as a counterweight to gravity and external forces, continuously pushing the temple segments together to maintain a secure fit regardless of extension length
3Adaptability or versatility
If a hyperextendable mechanism is added to the hinge, then temple adjustability improves, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The temple is divided into multiple separable segments connected by the hyperextension mechanism, allowing each segment to be manufactured independently using standard components, which simplifies the overall manufacturing process

AI summary
Eyewear having a frame, a hinge, and a hyperextendable temple. An extender is coupled to the hinge and the temple, and the extender extends with respect to the hinge allowing hyperextension of the temple with respect to the frame. The extender may include a bushing and a spring that allows the temple hyperextension, and which also creates a bias force to urge the temple against a user's head during use.
