Eyeglass Temple Arm Coupling Mechanism for Secure Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglasses with detachable temple arms require significant time and effort to assemble or disassemble due to loose screws, leading to inconvenient detachment and potential slipping off the frame.
Innovation Solution
The design features shoulder portions with upper and lower walls and a shaft member on the eyeglass frame, along with an inner flap and an anchoring section with an engaging and abutting portion on the temple arms, allowing for easy decoupling and secure pivoting within a predetermined range, reducing the complexity of attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to hinge the temple arms on the eyeglass frame, then the temple arms can be securely attached, but the screws become loose or worn after repeated use, requiring tool assistance for detachment
Solution Approach 1:
The temple arm attachment system is divided into separate functional components: the temple arm with its anchoring section, the shoulder portion with receiving slot, and the inner flap. This segmentation allows the temple arm to be easily detached by simply opening the inner flap, eliminating the need for tools while maintaining secure attachment during use.
Solution Approach 2:
The attachment mechanism transitions from a static screwed connection to a dynamic system where the inner flap can be opened and closed. The temple arm pivots between a closed position (parallel to frame) and an open position (perpendicular to frame), allowing easy detachment when needed while maintaining security during normal use.
2Ease of operation
If the temple arms are made detachable to save time and effort, then assembly and disassembly become easier, but the temple arms may slip off the eyeglass frame
Solution Approach 1:
The inner flap acts as an intermediary element between the temple arm and the eyeglass frame. When closed, it provides a secure retaining force that prevents the temple arm from slipping off. When opened, it allows easy detachment. This intermediary mechanism resolves the contradiction by providing both security and ease of operation.
Solution Approach 2:
The inner flap is pre-positioned to engage with the temple arm's anchoring section before the temple arm is fully attached to the frame. This preliminary engagement ensures that the temple arm is securely retained from the beginning, preventing slipping while maintaining ease of detachment when the flap is opened.
3Reliability
If the temple arms are confined to pivot within a pre-determined range, then secure coupling is achieved, but the range of motion is limited
Solution Approach 1:
The attachment mechanism utilizes the vertical dimension through the inner flap's opening and closing motion to control the temple arm's pivoting range. When the flap is closed, the temple arm is confined to a limited pivoting range for secure coupling. When the flap is opened, the temple arm can be detached completely. This dimensional approach resolves the contradiction by providing both secure coupling and controlled adaptability.

AI summary
The instant disclosure relates to a pair of eyeglasses, which includes an eyeglass frame and two temple arms pivotally connected thereto. Two shoulder portions are arranged on opposite ends of the eyeglass frame. Each one of the shoulder portions has an upper wall, a lower wall, and a shaft member. A receiving space is defined for each one of the shoulder portions. An inner flap is extended from the eyeglass frame toward the receiving space for each one of the shoulder portions. Each one of the temple arms has an anchoring section and an ear-resting section. Each one of the anchoring section has an engaging portion and an abutting portion. Each one of the temple arms can be at a closed position or an open position. At the open position, each one of the abutting portions is abutted to the corresponding flap.
