Eyeglass Nose Pad With Spherical Head for Adjustable Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nose pads for eyeglasses often lack adjustability and secure anchoring to the frame, leading to discomfort and limited positioning options.
Innovation Solution
A nose pad design featuring a first engagement means with vertical portions that elastically deform to couple with the eyeglass frame and a spherical head that allows rotation of a second engagement means, enabling adjustable positioning and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional nose pads are made with fixed metal structures, then anchoring strength is improved, but adjustability deteriorates
Solution Approach 1:
The nose pad is divided into two separate engagement means: a first engagement means fixed to the frame with a spherical head, and a second engagement means that can rotate around this spherical head. This segmentation allows the first part to provide strong anchoring while the second part provides adjustability for optimal positioning.
Solution Approach 2:
The second engagement means is designed to rotate around the spherical head of the first engagement means, introducing dynamic adjustability to the otherwise fixed structure. This rotational capability allows the nose pad to be positioned at different angles while maintaining secure attachment to the frame.
2Adaptability or versatility
If nose pads are made with adjustable mechanisms, then adaptability is improved, but device complexity deteriorates
Solution Approach 1:
The spherical head of the first engagement means provides a simple yet effective rotational interface. The curvature of the sphere allows for smooth rotation of the second engagement means without requiring complex mechanical joints, thereby maintaining structural simplicity while achieving adjustability.
3Ease of manufacture
If nose pads use insertion under pressure, then ease of manufacture is improved, but anchoring reliability deteriorates
Solution Approach 1:
The first engagement means is pre-formed with a spherical head that is already shaped to engage with the second engagement means. This preliminary shaping ensures that when assembled, the spherical head naturally guides and secures the second engagement means through rotation, providing reliable anchoring without requiring complex assembly procedures.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides a comfortable and stable fit with adjustable positioning, enhancing user comfort and ease of implementation while maintaining a secure attachment to the eyeglass frame.
Implementation Method 1
a first engagement means 2... provided with at least one vertical portion 5 and 6... which are elastically deformable, so that they can be coupled in the frame 4
Implementation Method 2
a substantially spherical head 8... adapted to engage in a corresponding cavity defined in a second engagement means 10, so that the second engagement means 10 can rotate about different axes around said substantially spherical head 8
