Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglasses with fixing portions suffer from structural weakness, deformation under external forces, and create blind spots, limiting their appearance and functionality.
Innovation Solution
A pair of eyeglasses featuring a primary lens and frame with snap-on units, including upper and lower engaging members and blocks, allowing the lens to be removably embedded, providing enhanced structural support and avoiding blind spots through a stable snapping engagement mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a fixing portion is added to connect upper and lower frame sections, then structural strength is improved, but blind spots are created and appearance is limited
Solution Approach 1:
The patent removes the traditional fixing portion that connects upper and lower frame sections from the front view of the eyeglasses. Instead, the connection is achieved through snap-on units located at the rear, allowing the frame sections to be interconnected without creating visible blind spots or limiting the appearance from the front.
2Strength
If a fixing portion is added to connect upper and lower frame sections, then structural strength is improved, but device complexity is increased
Solution Approach 1:
The patent divides the connection function into separate snap-on units that can be independently assembled. The upper and lower frame sections are segmented and connected through these modular snap-on units, which simplifies the overall structure compared to a continuous fixing portion while maintaining structural strength.
Solution Approach 2:
The snap-on units provide a dynamic connection mechanism that allows for easy assembly and disassembly of the frame sections. This replaces rigid permanent connections with flexible snap-fit connections, reducing structural complexity while maintaining strength.
3Strength
If fixing portion connects middle portions of frame sections, then bonding strength is enhanced, but frame deformation occurs under external force
Solution Approach 1:
The snap-on units are pre-designed with built-in elastic elements that are preliminarily configured to provide buffering capacity. When external forces are applied, these pre-configured elastic components absorb and distribute the stress, preventing frame deformation before it occurs.
4Ease of manufacture
If traditional embedding method is used, then manufacturing is simple, but connection strength is insufficient
Solution Approach 1:
The patent merges the lens embedding function with the snap-on connection mechanism. The snap-on units serve dual purposes: securing the lens to the frame while also providing enhanced connection strength through their elastic engagement, combining simplicity with strength.
Solution Approach 2:
The snap-on units incorporate elastic materials combined with rigid frame sections, creating a composite connection structure. This composite approach maintains ease of manufacture while significantly enhancing connection strength compared to traditional single-material embedding methods.
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
The snap-on units enhance the connection strength between the lens and frame, preventing deformation and blind spots, while offering a diverse appearance by eliminating the need for a fixing structure, thus improving the overall stability and aesthetics of the eyeglasses.
Implementation Method 1
an upper engaging block protruding from the upper frame section toward the primary lens for snapping engagement with the upper engaging member, a lower engaging member provided on a bottom portion of the primary lens, and a lower engaging block protruding from the lower frame section toward the primary lens for snapping engagement with the lower engaging member

AI summary
A pair of eyeglasses includes a primary lens, a primary lens frame including upper and lower frame sections, and at least one snap-on unit disposed between the primary lens and the primary lens frame and including upper and lower engaging members respectively provided on top and bottom portions of the primary lens, and upper and lower engaging blocks respectively protruding from the upper and lower frame sections toward the primary lens. The top and bottom portions of the primary lens are removably embedded in the upper and lower frame sections through snapping engagement between the upper engaging block and the upper engaging member and between the lower engaging block and the lower engaging member.
