Detachable Eyeglass Frame with Modular Hinge Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglass frames have complex hinge structures that make individual component accessibility difficult, leading to the potential abandonment of the entire frame when a single element is defective, as repairs are complicated and less accessible.
Innovation Solution
A detachable eyeglass frame design featuring a lens frame, temples, and joints with a resilient, asymmetrically V-shaped stainless steel hinge that allows for easy assembly and disassembly, enabling replacement of individual components, with the hinge comprising a temple insert, sleeve, and a screw-fastening mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a complex hinge structure is used to connect the lens frame and temples, then the connection strength and stability are improved, but the accessibility and ease of repair of individual components deteriorates
Solution Approach 1:
The hinge structure is divided into separate modular components including a temple insert, a hinge body, and a lens frame receiving component. These segmented parts can be independently accessed, removed, and replaced without affecting the entire eyeglass frame, thus improving repairability while maintaining connection strength through precise mechanical interfaces.
Solution Approach 2:
The temple insert is extracted as a separate removable component from the temple assembly. This allows the temple insert to be independently removed and replaced without disassembling the entire temple structure, significantly improving component accessibility and ease of repair while the hinge maintains robust connection through the extracted interface design.
2Stability of the object's composition
If a complex hinge structure is used to connect the lens frame and temples, then the connection stability is improved, but the ease of manufacture and assembly deteriorates
Solution Approach 1:
The hinge is segmented into distinct manufactured components (temple insert, hinge body, receiving component) that can be produced separately using standard manufacturing processes. This segmentation simplifies manufacturing of individual parts while the modular assembly provides stable connections through standardized interfaces.
Solution Approach 2:
The hinge components are designed with universal interfaces that can accommodate different lens frame and temple configurations. The standardized receiving ends and hinge structures allow the same hinge components to be used across multiple eyeglass frame types, improving ease of manufacture and assembly while maintaining connection stability.
3Ease of repair
If a detachable hinge design is used, then the ease of repair and component accessibility are improved, but the device complexity increases
Solution Approach 1:
The hinge is divided into three main segments: temple insert, hinge body, and lens frame receiving component. This segmentation enables easy repair and component replacement while the modular nature actually reduces overall system complexity by allowing independent optimization of each component without requiring complex integration.
Solution Approach 2:
The temple insert is received within the temple, which itself contains the hinge mechanism. This nested arrangement allows compact packaging of components while maintaining easy accessibility for repair. The temple insert nests within the temple structure, which in turn accommodates the hinge assembly, creating a space-efficient design that simplifies repair procedures.

AI summary
A detachable eyeglass frame includes a lens frame, a pair of hollow temples, a pair of temple inserts and a pair of hinges. The temple insert resembles a stick ending with a blade having a pocket for receiving the asymmetrical V-shaped hinge. The hinge has a column at one tip and a screw receiving column at the other. The temple insert is received by a sleeve formed within the temple and furthermore the hinge is inserted to the pocket of the temple insert for connecting the temple to the lens frame through a screw.
