Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional glasses structures that use screws to connect major components often experience loosening or detachment over time, causing inconvenience to users.
Innovation Solution
A screw-less glasses structure featuring a frame with elastic engagement members for linking temple arms and a bridge with an elastic clip member, eliminating the need for screws or soldering for assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If screws are used to connect frame, temple arms, and bridge, then the structure can be assembled, but the screws may easily loosen or fall off after use
Solution Approach 1:
The patent extracts and eliminates the screw components from the glasses structure, replacing them with elastic engagement members that are integrated into the temple arms and bridge. This removal of the problematic screw elements directly addresses the loosening issue while maintaining assembly capability through the elastic clipping mechanism.
Solution Approach 2:
The patent changes the connection mechanism from rigid screw-fastening to flexible elastic engagement. The elastic engagement members utilize material elasticity to provide continuous contact pressure, transforming the connection from a static, prone-to-loosening mechanical thread to a dynamic, self-maintaining elastic clamp that adapts to wear and maintains reliability.
2Reliability
If elastic engagement members are used to link temple arms to frame, then connection stability is improved, but device complexity increases
Solution Approach 1:
The patent merges the engagement member with the temple arm and bridge structures, creating integrated components rather than separate parts. The elastic engagement members are formed as part of the temple arms and bridge, eliminating the need for additional fastening hardware and reducing overall structural complexity while maintaining reliable connections.
Solution Approach 2:
The elastic engagement members serve multiple functions: they provide secure mechanical attachment, accommodate manufacturing tolerances through elastic deformation, and enable easy assembly and disassembly. This multi-functionality reduces the need for separate components for each function, thereby reducing overall device complexity.
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 structure provides secure and comfortable assembly without looseness, ensuring the glasses remain securely in place for the user.
Implementation Method 1
Each temple has an elastic engagement member at a front end thereof for clamping the respective end portion of the frame
Implementation Method 2
The bridge has an elastic clip member clamping the middle portion of the frame

AI summary
A glasses structure includes a frame, two temple arms and a bridge. The frame has two end portions arranged at lateral sides thereof and a middle portion connecting the two end portions. Each temple has a elastic engagement member at a front end thereof for clamping the respective end portion of the frame. The bridge has a elastic clip member clamping the middle portion of the frame. Therefore, the temple arms and the bridge could link to the frame without screw members.
