Spherical Glasses Arm Interface for Adjustable Smart Eyewear Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional glasses adjustment methods, which involve bending, are not applicable to glasses with built-in electronic components, as bending can damage these components and is not possible with certain materials, necessitating an alternative method for adjusting glasses arms without deformation.
Innovation Solution
A spherically-shaped mechanical interface with a generally spherical curvature, featuring at least two holes for securing the glasses arm to the frame using fasteners, allowing for rotational freedom and adjustment while preventing overextension of electronic components, and incorporating features like nut retention brackets and IPX seals for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional bending method is used to adjust glasses, then glasses can be adapted to different head shapes, but electronic components may be damaged and certain materials cannot be bent
Solution Approach 1:
The invention divides the glasses arm into multiple segments that can rotate relative to each other at hinge joints. This segmentation allows adjustment without bending the entire arm, protecting electronic components while achieving adaptability to different head shapes through controlled rotational movement at discrete joints.
Solution Approach 2:
The invention introduces dynamic adjustment mechanisms with multiple degrees of freedom, allowing the glasses arms to rotate and adjust to different positions. This dynamic capability enables adaptation to various head shapes while maintaining structural integrity and protecting electronic components from damage during adjustment.
2Adaptability or versatility
If conventional mating interfaces are used for glasses arms, then adjustment is possible, but undesirable offsets occur at certain points along the arms
Solution Approach 1:
The invention employs spherical or spheroidal mating surfaces at the hinge joints, allowing rotational movement while maintaining precise alignment. The curved spherical interface enables adjustment through rotation without creating linear offsets, preserving manufacturing precision while achieving adaptability.
3Adaptability or versatility
If glasses frame or arms are bent for adjustment, then fit to head shape is improved, but structural integrity may be compromised and adjustment is limited
Solution Approach 1:
By segmenting the glasses arm into multiple rigid sections connected by rotational hinges, the invention maintains the structural integrity of each segment while achieving overall adaptability. The segmented structure avoids the need to bend individual components, preserving their strength while allowing adjustment through hinge rotation.
Solution Approach 2:
The hinge joint acts as an intermediary mechanism between the rigid glasses arm segments and the user's head. Instead of bending the arms directly, the hinge mediates the adjustment by providing controlled rotational movement, maintaining structural integrity while achieving the desired fit.

AI summary
A spherically-shaped mechanical interface is configured for coupling a glasses arm with a frame. The spherically-shaped mechanical interface comprises a surface having a generally spherical curvature and at least two holes extending through the surface. The surface is configured to be secured to a portion of a glasses arm by a fastener that is received along a first axis through a first hole of the at least two holes. The surface is configured to be secured to the portion of the glasses arm by another fastener that is received along a second axis, distinct from the first axis, through a second hole of the at least two holes.
