Solution Overview

Problem

Existing hinges in furniture and other pivoting elements face challenges in routing cables invisibly and protecting them from damage during pivoting movements, especially in applications like tables and doors where cables need to be routed for power supply and electronic connections.

Innovation Solution

A hinge design featuring a first and second hinge wing, each with a cable guide, and a connecting element with a cable channel that forms a continuous cable guide in the folding position, ensuring cables are guided smoothly and protected from damage while maintaining an invisible and compact arrangement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cables are routed openly on the table top, then cable accessibility is improved, but cable protection from damage and aesthetic appearance deteriorates

Engineering Contradiction:
Improvecable accessibilityVSAvoidcable damage and aesthetic appearance
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A cable guide system consisting of a first cable guide in the first hinge wing, a second cable guide in the second hinge wing, and a cable duct in the connecting element serves as an intermediary structure. This mediator channels cables through the hinge mechanism rather than across the table top surface, protecting cables from damage while maintaining routing functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The cable routing path is moved from the horizontal table top surface to the vertical/three-dimensional space within the hinge mechanism. By utilizing the depth and structure of the hinge wings and connecting element, the system routes cables through a different spatial dimension, achieving both protection and invisibility.

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

2Object-affected harmful factors

If cables are routed through the hinge mechanism, then cable protection and invisibility are improved, but cable routing complexity increases

Engineering Contradiction:
Improvecable protection and invisibilityVSAvoidcable routing structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The cable routing system is divided into three functional segments: a first cable guide in the first hinge wing, a second cable guide in the second hinge wing, and a cable duct in the connecting element. Each segment performs a specific function (guiding, transitioning, protecting), and together they form a complete routing solution without requiring a single complex structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hinge mechanism serves multiple functions: it provides the mechanical pivoting function for the table top sections and simultaneously serves as the cable routing infrastructure. The cable guides and duct integrated into the hinge components allow the same structural elements to fulfill both mechanical and electrical routing roles.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If the hinge is designed with integrated cable guides, then cable protection is improved, but hinge manufacturing complexity increases

Engineering Contradiction:
Improvecable protectionVSAvoidhinge manufacturing
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The cable guide features are merged with the existing hinge wing and connecting element structures. Rather than adding separate cable protection components, the patent integrates cable guides directly into the hinge wings and the duct into the connecting element, combining mechanical support and cable routing functions into unified components.

Inventive Principle:
Principle #5Merging (Combining)
