Temple and Side Shield Assembly with Elastic Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing side shield assembly structures for eyeglasses are not stable and can be easily separated from the temple, leading to unreliable protection against light and foreign objects.
Innovation Solution
The assembly structure includes a temple with a slot and engaging protrusions, and a side shield with an insert piece and second introduction slopes, allowing for stable assembly and secure engagement of the side shield on the temple without the need for hand tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the side shield is designed to be easily assembled and disassembled from the temple, then the ease of operation is improved, but the reliability of the connection deteriorates
Solution Approach 1:
The connection structure transitions from a static rigid connection to a dynamic controlled connection. The temple arm incorporates a resilient portion that can elastically deform, allowing the side shield to be easily inserted and removed while maintaining a stable connected state during normal use. The resilient portion acts as a spring mechanism that provides both ease of operation and connection reliability.
Solution Approach 2:
The temple arm is divided into distinct functional segments: a resilient portion with elastic deformation capability, a slot portion for guiding the side shield, and a fixed portion for stable mounting. This segmentation allows each part to perform its specific function optimally - the resilient portion provides ease of operation, while the fixed portion ensures connection reliability.
2Device complexity
If the side shield uses a simple insertion structure without complex engagement mechanisms, then the device complexity is reduced, but the reliability of protection deteriorates
Solution Approach 1:
The resilient portion of the temple arm provides dynamic elastic deformation that enables simple insertion of the side shield while ensuring reliable protection. The elastic property allows the structure to absorb impact forces and maintain secure connection without complex engagement mechanisms like screws or clips.
Solution Approach 2:
The resilient portion automatically provides the necessary engagement force through its elastic deformation, eliminating the need for additional fastening mechanisms. The side shield self-secures into the slot portion and is held in place by the elastic recovery force of the resilient portion, achieving reliable protection with minimal structural complexity.

AI summary
The invention relates to an assembly structure of temple and side shield, which includes a temple, a spectacles frame and a side shield. The temple comprises a slot provided on thereof, two engaging protrusions each provided on a pair of corresponding walls of the slot, and a first introduction bevel provided on each side of the two engaging protrusions. The side shield includes an insert piece upward protruded on the top end thereof, a through hole passing through the wall of the insert piece, and two second introduction slopes arranged on both sides of the tip of the insert piece. Insert the insert piece of the side shield, and under the guidance of the first introduction bevels and the second introduction slopes, after the tip of the insert piece passes through the two engaging protrusions, the two engaging protrusions are correspondingly embedded in the through hole of the insert piece.
