Multi-Chamber Textile Hose for Media Guide Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective solutions for media lines in working devices, such as excavators and grippers, fail to adequately protect against mechanical loads and external disruptions like weather and impacts, leading to damage and kinking of cables and hoses.
Innovation Solution
A flexible textile hose with a multi-chamber system, featuring a central chamber and external chambers with protective elements, provides comprehensive protection against mechanical and thermal loads, ensuring secure hold and stability through elastic properties and inherent stability of the textile material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective sheath is used for media lines in working devices, then the media lines are protected against mechanical loads and external disruptions, but the protective sheath may kink or be damaged when connecting stationary base to moving equipment
Solution Approach 1:
The protective hose is divided into multiple chambers (central chamber for media guide, outer chambers for protective elements) separated by partition walls. This segmentation allows independent movement of each chamber, preventing kinking while maintaining protection. The central chamber can move with the media guide while outer chambers with rigid protective elements maintain structural integrity.
Solution Approach 2:
The protective hose combines flexible textile material with rigid protective elements (metal or plastic) within the multi-chamber structure. This composite construction provides both flexibility for movement and rigidity for protection against mechanical loads and external disruptions.
2Strength
If a rigid protective structure is used to protect against mechanical loads and impacts, then protection against buckling loads is improved, but flexibility and ability to accommodate movement are reduced
Solution Approach 1:
By dividing the hose into separate chambers, the invention allows rigid protective elements to be placed in outer chambers while the central chamber remains flexible for media guide movement. Each chamber can deform independently, maintaining overall flexibility while providing rigid protection where needed.
Solution Approach 2:
Different chambers have different properties: the central chamber is flexible to accommodate media guide movement, while outer chambers contain rigid protective elements for localized protection against mechanical loads. This local differentiation of properties resolves the contradiction between rigidity and flexibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents damage from mechanical loads and weather exposure, maintaining the integrity of media guides under high stress conditions, including buckling loads, while allowing for movement and flexibility.
Implementation Method 1
due to the elastic properties of the textile material of the hose, it stretches somewhat when the media guide is inserted into the central chamber and the protective elements are inserted into the outer chambers, so that the hose material is subjected to a certain tension on the media guide or the protective element applied, so that a secure hold is given
