Solution Overview

Problem

Existing eyeglasses designs suffer from temple damage due to restricted swinging motion along a plane parallel to the hinge shaft, lack of outward swinging capability, and non-replaceable temple connecting assemblies, leading to resource waste.

Innovation Solution

A spectacle frame and temple connecting mechanism featuring a hinge member with a temple swing mechanism, including a hinge groove, radial relief grooves, and a reset mechanism, allowing temples to swing parallel to the hinge shaft, preventing axial play, and enabling easy disassembly for repair or replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the temple is hinged to the spectacle frame with a fixed connection structure, then the connection is simple and reliable, but the temple cannot swing along a plane parallel to the hinge shaft, causing easy damage when subjected to upward or downward swinging forces

Engineering Contradiction:
Improvetemple connection reliabilityVSAvoidtemple swinging motion capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The hinge main body is designed to rotate relative to the hinge member through a hinge shaft, transforming the fixed connection into a dynamic joint that allows the temple to swing along a plane parallel to the hinge shaft. This dynamic capability enables the temple to accommodate upward or downward swinging forces, resolving the contradiction between connection reliability and motion adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention introduces a new dimension of motion by enabling the temple to swing not only in the traditional hinge direction but also along a plane parallel to the hinge shaft through the hinge main body's rotation. This additional degree of freedom provides the temple with versatile motion capability while maintaining connection reliability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If the temple connecting assembly is fixedly installed in the temple, then the connection is stable, but the assembly cannot be removed for repair or replacement, causing unnecessary waste of resources

Engineering Contradiction:
Improvetemple connecting assembly stabilityVSAvoidtemple connecting assembly replaceability
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The temple connecting assembly is divided into separable components: the hinge member attached to the frame, the hinge main body, and the temple. This segmentation allows the hinge main body to be removed from the temple for repair or replacement while leaving the temple intact, resolving the contradiction between connection stability and repairability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design enables selective replacement of only the hinge main body when damaged, rather than discarding the entire temple. The hinge main body can be recovered and replaced independently, reducing resource waste while maintaining the stability of the overall connection system.

Inventive Principle:
Principle #34Discarding and recovering

3Device complexity

If the temple is subjected to outward swinging force when eyeglasses are in open state, then the temple structure is simple, but the temples cannot rotate outwards relative to the frame, likely to damage the eyeglasses temples

Engineering Contradiction:
Improvetemple structure complexityVSAvoidtemple damage resistance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The hinge main body's ability to rotate relative to the hinge member provides the temple with dynamic outward rotation capability. This simple dynamic mechanism allows the temple to rotate outward when subjected to external forces, preventing damage without adding complex structural elements.

Inventive Principle:
Principle #15Dynamics
