Eyeglasses With Segmented Flexible Upper Rims
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeglasses with interchangeable lenses lack ease of lens replacement and secure lens retention, often requiring tools and risking lens damage during insertion and removal.
Innovation Solution
A pair of eyeglasses with a main frame and upper rim portions that are flexible and can be pulled away from rigid outer portions, allowing lenses to be easily swapped without tools, with lenses sandwiched between flexible inner and rigid outer portions for secure retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lenses are inserted upwardly into the frame as in prior art, then lens replacement is possible, but the lens may fall out if not inserted correctly
Solution Approach 1:
Instead of inserting lenses upwardly into the frame as in prior art, this invention inverts the insertion direction by having lenses inserted downwardly between the upper rim and lower rim. The flexible upper rim portions are pulled away from rigid outer portions to create insertion space, and lenses are pushed downward into position where they are retained by the lower rim portions. This inverted approach ensures proper insertion direction and secure retention.
2Reliability
If lenses are sandwiched between rigid portions as in prior art, then lens retention is improved, but the lens may break during insertion and removal
Solution Approach 1:
The upper rim portions incorporate flexible inner portions that can be pulled away from rigid outer portions. This flexibility allows the rim to open up during lens insertion and removal, creating sufficient clearance for users to manipulate lenses without excessive force. The flexible material deforms to accommodate lens insertion while the rigid outer portions maintain structural integrity and secure retention, preventing lens breakage.
3Adaptability or versatility
If a single pair of glasses is used with interchangeable lenses, then the need for multiple pairs is reduced, but the mechanism for lens replacement becomes complex
Solution Approach 1:
The upper rim is segmented into flexible inner portions and rigid outer portions, allowing independent movement of each segment. This segmentation enables the flexible portions to be pulled away to create insertion space while the rigid portions maintain structural support. The segmented design provides a simple, intuitive lens replacement mechanism that does not require complex tools or procedures, maintaining ease of use while enabling lens interchangeability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a single pair of glasses to accommodate multiple prescriptions, allowing users to quickly change lenses without tools and ensuring secure insertion and removal, reducing the need for multiple pairs and minimizing lens damage.
Implementation Method 1
Right and left upper rim inner portions are flexible and right and left upper outer portions are rigid, such that the right and left upper rim inner portions can be pulled away from said right and left upper outer portions
Implementation Method 2
These lenses are sandwiched between flexible inner portions and rigid outer portions of the upper rims of the eyeglasses

AI summary
A pair of eyeglasses having two-part upper rim portions. One part is made of a flexible material and the other part is made of a rigid material. The flexible portion can be pulled away from the rigid part by a user, allowing a user to interchange lenses without the use of any tools.
