Solution Overview
Problem
Conventional eyeglasses require small screws for assembly, making it difficult and time-consuming to replace components quickly, and there is a risk of losing these small screws.
Innovation Solution
The eyeglasses feature a quick detachable structure with recesses and wedge units on the lens and temples, allowing for secure and rapid attachment and detachment without the need for screws, using protrusions, niches, and wedging bumps to facilitate easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional screw connection is used to attach temples to lens, then the connection is secure and reliable, but the replacement of components is time-consuming and requires small sized screwdrivers
Solution Approach 1:
The connection structure is segmented into separate modular components: a connection piece on the temple and a corresponding recess on the lens. This segmentation allows the temple to be quickly detached and replaced from the lens without affecting other components, enabling rapid component replacement while maintaining secure connection through the interlocking geometry of the segmented parts.
Solution Approach 2:
Instead of using screws that require rotational insertion and tightening, the invention inverts the approach by using a press-fit connection where the connection piece is inserted into the recess and secured through elastic deformation and geometric interlocking. This inversion eliminates the need for screwdrivers and small sized tools, making component replacement faster and easier.
2Device complexity
If small sized screws are used for assembly, then the connection is secure, but the screws may be lost and require specific small sized screwdrivers
Solution Approach 1:
The invention merges the connection function into an integrated connection piece that is part of the temple structure, eliminating the need for separate screws. The connection piece includes both the insertion portion and the elastic portion as unified components, simplifying the assembly by removing small sized screws and their associated tools while maintaining secure attachment through the elastic-deformation-based connection mechanism.
Solution Approach 2:
The invention extracts and eliminates the screw component from the assembly system. By replacing screws with a connection piece that uses elastic deformation and geometric interlocking, the design removes the need for small sized screws and specific screwdrivers, thereby simplifying the device and reducing the number of small parts that could be lost.
3Loss of time
If quick detachable structure is implemented, then component replacement is fast and easy, but the connection security must be maintained
Solution Approach 1:
The connection piece is pre-formed with specific geometric features including an insertion portion and an elastic portion positioned at predetermined locations. The elastic portion is pre-configured to deform during insertion and then recover to lock the temple securely to the lens. This preliminary structuring ensures that the quick detachable mechanism maintains reliable connection security while enabling fast replacement.
Solution Approach 2:
The invention utilizes parameter changes in the elastic portion of the connection piece. During insertion, the elastic portion deforms (changes in shape and position parameters) to allow passage through the recess. Once inserted, the elastic portion recovers its original shape, creating a secure locked connection. This dynamic parameter change enables both quick attachment and reliable connection security without requiring tools or complex mechanisms.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables quick and secure attachment and detachment of the temples to the lens, allowing for easy replacement of components without the need for small screws, enhancing user convenience and reducing the risk of loss.
Implementation Method 1
Each of the wedge units has a shallow groove wall, a deep groove wall, a settling bump, and a wedging bump... The first protrusion, the second protrusion, the first niche, and the second niche are wedged with the shallow groove wall, the deep groove wall, the settling bump, and the wedging bump respectively, so the temples are secured to the lens.

AI summary
An eyeglasses with quick detachable temple has a lens and two temples. Opposite sides at both ends of the lens are defined as terminal sides respectively, and recesses are formed on the terminal sides respectively. Each recess is formed with a first and second protrusions, and a first and second niches, wherein the first protrusion is opposite to the second protrusion. The first and second niches are adjacent to the first and second protrusions respectively. A distance between the first and second niches is greater than a distance between top ends of the first and second protrusions. Each temple has a wedge unit, and the shape of the wedge unit is corresponding to the shape of the recess. The wedge unit comprises a shallow groove wall, a deep groove wall, a settling bump, and a wedging bump.
