Eyeglass Frame Lens Lock via Split End Piece Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeglass frames lack an efficient mechanism for easily removing and replacing lenses without tools, limiting the ability to switch between different frames or lenses optimized for various conditions or styles.
Innovation Solution
The eyeglass frame lens lock system, featuring split end pieces and locks on the temples or bridge, allows for manual lens removal and replacement by disengaging the end pieces from the locks, enabling seamless transition between frames and lenses with different coatings or styles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional eyeglass frame design is used, then the structure is simple and easy to manufacture, but the lens cannot be easily removed or replaced without tools
Solution Approach 1:
The end piece is divided into a first portion and a second portion that can be separated from each other. The lock is configured to receive both portions and secure them together, allowing the lens to be removed by separating the portions and resecured by engaging them in the lock. This segmentation enables easy lens exchange while maintaining frame integrity.
Solution Approach 2:
The end piece is received within the lock structure, with the lock containing both portions of the end piece. The lock acts as a nested container that secures the end piece portions together, enabling tool-free lens removal and replacement through a simple separating and re-engaging action.
2Reliability
If a secure lens retention mechanism is used, then the lens is firmly held in place, but the mechanism becomes complex and requires tools for lens exchange
Solution Approach 1:
The end piece is segmented into separable portions that can be easily divided and re-engaged. The lock is designed to receive and secure both portions, providing reliable lens retention when engaged and easy removal when the portions are separated, thus resolving the contradiction between security and ease of operation.
Solution Approach 2:
The lock mechanism transitions between a locked state (when end piece portions are engaged) and an unlocked state (when portions are separated). This dynamic design allows the system to provide secure retention during normal wear and easy access during lens exchange, adapting to different operational requirements.
3Ease of operation
If a tool-free lens removal mechanism is implemented, then the lens can be exchanged easily, but the locking mechanism becomes more complex
Solution Approach 1:
The end piece is divided into two separable portions that can be easily separated by hand. The lock is configured to receive both portions and secure them together through a simple engagement action, enabling tool-free lens exchange while keeping the overall mechanism relatively simple despite the added locking functionality.

AI summary
An eyeglass frame is disclosed comprising a bridge and two rims connected by the bridge. Each rim is configured to contain a lens. The eyeglass frame also comprises two split end pieces. Each split end piece comprises a first portion and a second portion. Each split end piece is coupled to and extends outward from a corresponding rim of the two rims on a side of the corresponding rim opposite the bridge. The eyeglass frame further comprises two temples. Each temple comprises a lock on an end of the temple. The lock is configured to at least partially contain both the first portion and the second portion of the split end piece and secure the temple to the corresponding rim and secure the lens within the corresponding rim.
