Eyeglass Temple Hinge Structure for Stable Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglass temple designs face challenges in maintaining a stable unfolded state and preventing deformation under external forces, often requiring additional coupling members that increase manufacturing costs and complexity.
Innovation Solution
The eyeglass temple design incorporates a hinge axis with extension portions and supports that provide elastic restoring forces through torsion bars and inclined angles, allowing for stable folding and unfolding without external components like hinges or screws, using a simple structure to connect directly to the glass frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate coupling members (bolts or hinges) are used to rotatably support eyeglass temples, then the eyeglass temples can be securely attached to the glass frame, but manufacturing costs increase and assembly process complexity increases
Solution Approach 1:
The patent merges the coupling member function into the eyeglass temple structure itself by forming hinge protrusions directly on the temple. The temple body integrates the coupling features through bent extension portions that engage with the glass frame, eliminating the need for separate bolts or hinges while maintaining secure attachment
Solution Approach 2:
The eyeglass temple structure performs its own coupling function through self-formed hinge protrusions. The extension portions are bent to create engagement features that automatically secure the temple to the glass frame during assembly, making the temple self-sufficient for attachment without requiring external coupling components
2Device complexity
If hinge protrusions are formed by bending eyeglass temples and inserted into hinge holes, then separate coupling members are eliminated, but the eyeglass temples are supported by only one surface and cannot prevent arrangement position changes under external force
Solution Approach 1:
The support function is segmented into multiple independent features: hinge protrusions for rotational support, extension portions for lateral positioning, and bending portions for angular stabilization. Each segment performs a specific support function, collectively providing multi-surface support that prevents arrangement position changes under external force
Solution Approach 2:
The patent transitions from single-surface support to multi-dimensional support by extending support features in multiple directions. The extension portions protrude laterally from the hinge protrusions, adding lateral dimension support, while the bending portions create angular support relationships, transforming the support system from one-dimensional to multi-dimensional
3Ease of manufacture
If a simple structure without separate coupling members is used, then manufacturing costs decrease and assembly efficiency increases, but the eyeglass temples cannot be stably maintained in folded or unfolded states
Solution Approach 1:
The patent incorporates elastic deformation capabilities into the temple structure through flexible bending portions. These portions can dynamically adjust during folding and unfolding operations, providing elastic restoring forces that help maintain the temple in either folded or unfolded states. The dynamic elastic behavior enables stable state maintenance without requiring additional locking mechanisms or complex structures

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 reduces manufacturing costs, enhances assembly efficiency, and ensures the eyeglass temples remain stable in both folded and unfolded states by utilizing elastic deformation to resist external forces, preventing damage and maintaining the intended arrangement.
Implementation Method 1
elastic restoring force through elastic distortion deformation of the second extension portion
Implementation Method 2
the second extension portion is a torsion bar providing elastic restraint or elastic restoring force against distortion between the first extension portion and the first support
Implementation Method 3
elastic restoring force through elastic deformation of an interval or an inclination angle between the first support and the second support
