Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a snap-in slingshot structure is used for eyeglass temple connection, then elastic functionality is achieved, but structure complexity and cost increase
Solution Approach 1:
The connecting member is divided into distinct functional segments: a body portion inserted through the slot, a spring portion providing elastic force, and a limiting structure with grooves that work with the elastic member. This segmentation allows each part to perform its specific function while simplifying the overall assembly compared to a monolithic slingshot design.
Solution Approach 2:
The elastic limiting structure extracts the essential elastic functionality from the complex slingshot assembly and implements it through a simplified mechanism consisting of a connecting member with grooves and a separate elastic member. This extraction eliminates unnecessary components while retaining the core elastic function.
2Reliability
If laser welding and manual spring installation are used, then elastic connection is achieved, but installation efficiency decreases
Solution Approach 1:
The connecting member merges multiple functions into a single integrated component: it provides the mechanical connection through the slot, incorporates the elastic element through the groove structure, and integrates the limiting mechanism. This merging eliminates the need for separate spring installation and welding operations, significantly improving installation efficiency.
Solution Approach 2:
The connecting member is pre-formed with the groove structure and slot configuration during manufacturing, so that upon assembly, the elastic member automatically engages with the grooves to provide the limiting function. This preliminary preparation of the connecting member structure eliminates the need for complex on-site assembly operations.
3Ease of operation
If traditional elastic hinge connection is used, then temple rotation is enabled, but installation complexity and cost remain high
Solution Approach 1:
The connecting member serves multiple functions simultaneously: it enables temple rotation through the slot and notch mechanism, provides elastic force through the integrated spring portion, and implements the limiting function through the groove structure. This multi-functionality reduces installation complexity by eliminating the need for separate components for each function.

Function Achieved in This Case
This solution enhances installation efficiency, reduces costs, and provides a simple structure while offering elastic hand feedback and automatic pop-open functionality.
Implementation Method 1
the elastic member is abutted against the connecting member; and when the eyeglass temple is opened and closed in place, the elastic member is inserted in the first groove or the second groove to limit a rotation of the eyeglass temple
