Solution Overview

Problem

Conventional eyeglass hinges are difficult to retrofit with cable guides for electronic eyeglasses, and they do not adequately protect cables while ensuring easy mounting and dismounting, particularly for maintenance purposes, and fail to define accurate functional positions for temple movement.

Innovation Solution

A central part for an eyeglass hinge with articulation regions and a cable guide opening that allows easy mounting and dismounting, protecting the cable and enabling accurate temple positioning through latching elements, while guiding cables from the temple to the frame with reduced bending angles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a conventional eyeglass hinge is used, then the structure is simple, but it cannot provide adequate cable protection and guidance for electronic eyeglasses

Engineering Contradiction:

Improvecable protectionVSAvoidhinge structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The hinge is divided into separate functional components: a first arm connecting to the frame, a second arm connecting to the temple, and a dedicated cable guide opening. This segmentation allows each component to perform its specific function optimally while maintaining overall structural simplicity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cable guide opening acts as an intermediary structure that provides a protected pathway for the cable between the temple and frame. This mediator protects the cable from external damage while allowing necessary movement, resolving the contradiction between protection and simplicity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the temple is hinged directly to the frame with a large pivoting angle, then the functional range is sufficient, but the cable bending angle becomes too large causing stress and potential damage

Engineering Contradiction:

Improvecable stress reductionVSAvoidpivoting angle

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The total pivoting movement is segmented into two separate partial pivoting movements at different articulation points. The first articulation region provides a first partial pivoting movement, and the second articulation region provides a second partial pivoting movement, distributing the bending stress across multiple smaller angles rather than one large angle.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cable path is extended into a third dimension by routing it through the cable guide opening that penetrates perpendicular to the articulation axes. This spatial arrangement allows the cable to follow a more gradual path, reducing bending stress while maintaining the necessary pivoting range.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Object-affected harmful factors

If the cable guide opening is closed on all sides, then cable protection is maximized, but cable insertion and maintenance become difficult

Engineering Contradiction:

Improvecable protectionVSAvoidcable access

Core Design Contradiction:

Object-affected harmful factorsVSEase of repair

Solution Approach 1:

The cable guide opening transitions from a closed state during operation to an open state during maintenance. The opening is configured to be accessible when the hinge is disassembled, allowing dynamic access to the cable for insertion and removal while maintaining protection during normal use.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The hinge structure is designed to be disassembled before cable maintenance is needed. By preliminarily preparing the disassembly process, the cable guide opening becomes accessible, allowing easy cable insertion or removal without requiring the opening to be permanently exposed.

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If conventional hinges are retrofitted for electronic functions, then existing eyeglasses can be upgraded, but the modification is difficult and expensive

Engineering Contradiction:

Improveretrofit capabilityVSAvoidmodification cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The hinge design incorporates universal features that can accommodate both traditional eyeglasses and electronic eyeglasses with cable requirements. The cable guide opening and articulation regions can be integrated into existing hinge designs without requiring complete redesign, enabling cost-effective retrofitting of conventional eyeglasses.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A central part for an eyeglass hinge includes first articulation region, which is designed to connect, with articulation about a first articulation axis, the central part to a frame of eyeglasses; a second articulation region, which is designed to connect, with articulation about a second articulation axis, the central part to a temple of the eyeglasses; and a cable guide opening, which extends through the central part perpendicularly to the articulation axes and is designed for the feeding of a cable from the temple to the frame through the central part, the cable guide opening being open in the direction of the articulation axes at least on one side.
