Embedded Magnets in Eyeglass Frames for Secure Auxiliary Lenses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnetically coupled auxiliary lenses for eyeglasses often add weight, risk scratching the primary lenses, and are limited by complex manufacturing processes that restrict frame choices and aesthetics, while also being prone to detachment and lacking design finesse.
Innovation Solution
The solution involves embedding rare earth magnets within the primary eyeglass frame front, allowing for on-demand manufacturing of custom frames and lenses using CNC machining and 3D printing, which ensures a lightweight, aesthetically pleasing, and securely attachable auxiliary lens system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic appendages are used to attach auxiliary lenses to primary eyeglasses, then magnetic attachment is achieved, but weight is added and risk of scratching primary lenses increases
Solution Approach 1:
The patent removes the magnetic appendages from the auxiliary lenses and extracts only the essential magnetic attachment function. Magnets are embedded directly into the primary eyeglass frame front, eliminating the need for separate magnetic clips or appendages that add weight and scratching risk.
Solution Approach 2:
The magnets are nested within cavities in the primary eyeglass frame front, with the frame material encapsulating the magnets. This nesting approach integrates the magnetic function into the existing frame structure without adding external components.
2Productivity
If conventional manufacturing processes are used for eyeglass frames, then production efficiency is maintained, but frame choices are restricted and aesthetic design is limited
Solution Approach 1:
The patent incorporates magnet embedding as an integral step in the frame manufacturing process itself, rather than as a separate post-processing step. This preliminary integration allows for greater design flexibility while maintaining manufacturing efficiency.
Solution Approach 2:
The manufacturing process is designed to accommodate multiple frame styles and designs while incorporating the magnetic attachment function universally across different frame types, enabling both customization and mass production.
3Reliability
If magnets are embedded in the primary eyeglass frame front, then attachment security is improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the magnet embedding process with the frame manufacturing process, combining two operations into one integrated workflow. This reduces overall manufacturing complexity compared to separate steps.
Solution Approach 2:
The frame manufacturing process itself provides the means for magnet embedding through integrated CNC machining or 3D printing capabilities, allowing the system to self-configure the magnetic attachment features without requiring separate specialized equipment or processes.
4Adaptability or versatility
If on-demand manufacturing is used for custom frames and lenses, then design customization is improved, but manufacturing time increases
Solution Approach 1:
The patent uses digital modeling and parametric design approaches where frame and lens parameters can be easily adjusted and modified. This allows for rapid customization without requiring complete redesign or lengthy manufacturing processes.
Solution Approach 2:
Standardized components and pre-configured magnetic attachment systems are prepared in advance, allowing customizations to be made by assembling pre-manufactured elements rather than creating everything from scratch for each custom order.
