Solution Overview

Problem

Existing devices for guiding and protecting lines, such as energy chains and protective hoses, face challenges including susceptibility to wind, high engineering effort for integration, limited mobility, difficulty in assembly and disassembly, maintenance intensity, inability to replace individual lines, and material selection issues, especially in extreme conditions.

Innovation Solution

A cable guideline chain with a link chain or steel rope as a central element, featuring cable guide elements with a central element contact area that surrounds and fixes the central element, allowing for two-point attachment, easy assembly and disassembly, and the ability to add, remove, or repair lines without specialized tools, while providing protection and heat dissipation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an energy chain is used to guide cables, then cable guidance and protection is achieved, but the device becomes complex to manufacture, install and maintain

Engineering Contradiction:
Improvecable guidance and protectionVSAvoidmanufacturing and installation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The energy chain is divided into individual link elements that can be separately manufactured and then assembled together. Each link element is a simple U-shaped component that can be produced independently, reducing manufacturing complexity while maintaining the overall functionality of cable guidance and protection.

Inventive Principle:
Principle #1Segmentation

2Reliability

If an energy chain is used to guide cables, then cable protection is provided, but maintenance becomes difficult and time-consuming

Engineering Contradiction:
Improvecable protectionVSAvoidmaintenance difficulty
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The chain is composed of modular link elements that can be individually removed and replaced. If one link becomes damaged or worn, only that specific link needs to be replaced rather than the entire chain, significantly reducing maintenance time and effort.

Inventive Principle:
Principle #1Segmentation

3Reliability

If an energy chain is used, then cables can be guided, but the chain is heavy when using metallic links

Engineering Contradiction:
Improvecable guidance capabilityVSAvoidchain weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The material of the link elements can be changed from heavy metallic materials to lighter materials such as reinforced plastics or composite materials. This parameter change maintains the structural integrity and cable guidance functionality while significantly reducing the overall weight of the chain.

Inventive Principle:
Principle #35Parameter changes

4Device complexity

If protective conduit is used instead of energy chain, then fewer individual parts are involved, but individual wires cannot be replaced or repaired

Engineering Contradiction:
Improvenumber of partsVSAvoidwire replaceability
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

The protective structure is segmented into individual removable link elements rather than being a continuous conduit. This segmentation allows the links to be opened and reconfigured, enabling access to individual wires for replacement or repair while maintaining overall structural protection.

Inventive Principle:
Principle #1Segmentation

5Reliability

If an energy chain is used, then cables can be guided, but significant engineering effort is required for integration with specified radii and guides

Engineering Contradiction:
Improvecable guidanceVSAvoidintegration engineering effort
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The chain structure provides inherent flexibility and adaptability, allowing it to conform to various installation paths and radii without requiring precise pre-engineering of guide structures. The individual links can articulate to accommodate different geometries, reducing the engineering effort needed for integration.

Inventive Principle:
Principle #15Dynamics
