Eyeglass Translating Clip for Neck Strain Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of multifocal eyeglasses often experience discomfort and strain due to the need to contort their head and neck to align the near portion of the lens with objects at or above eye level, and existing solutions do not adequately address these issues.
Innovation Solution
A translating clip that allows for infinitely variable adjustment of the eyeglass frame's height relative to the nose and eyes, combined with a detachable/attachable illumination system, such as LEDs, to provide comfortable and flexible positioning and lighting for various tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multifocal lenses are used to correct presbyopia, then distance and near vision are improved, but the user must contort head and neck to align the near portion with objects at or above eye level
Solution Approach 1:
The patent applies the dynamics principle by making the eyeglass frame height adjustable through a translating clip mechanism. The frame can be dynamically repositioned vertically along the temple arm, allowing users to adjust the near portion of the lens to different heights to match various viewing distances and angles, thereby eliminating the need for uncomfortable head contortions while maintaining proper vision correction.
Solution Approach 2:
The translating clip mechanism segments the eyeglass system into adjustable components. The clip separates the frame from the temple arm, creating an independent adjustment mechanism that allows the frame height to be modified without affecting the overall structure or the lens prescription, enabling flexible positioning for different viewing scenarios.
2Ease of operation
If existing adjustable bridge structures are used to move the eyeglass frame, then the near portion can be positioned higher, but the device complexity increases
Solution Approach 1:
The patent extracts the adjustment function from the traditional fixed bridge structure and relocates it to the temple arm area. The translating clip is positioned away from the nose bridge, utilizing the temple arm as the adjustment mechanism. This extraction simplifies the overall design by removing complex bridge structures while maintaining the ability to adjust frame height through a simpler clip mechanism on the temple arm.
Solution Approach 2:
The translating clip acts as an intermediary mechanism between the temple arm and the frame. Instead of modifying the bridge structure directly, the clip serves as a mediating component that transfers the adjustment capability from the temple arm to the frame, simplifying both the bridge and the adjustment mechanism while achieving the desired frame positioning flexibility.

AI summary
A translating clip, including a clip on portion adapted to grippingly engage an eyeglass frame, an adjustment portion, and a nose bridge engaging portion. The adjustment portion enables adjustment of an engagement distance between a lower end of the nose engaging portion and the eyeglass frame.
