Abrasive Media Hose Line With Embedded Wear Detection Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hose lines used for transporting abrasive media often suffer from wear-induced damage, leading to leaks, which are difficult to detect externally and result in high repair costs and downtime due to the inability to visually assess inner wall wear.
Innovation Solution
Incorporating an electrically conductive insert embedded in the hose wall, separate from the reinforcing element, which forms an electrical circuit that can detect wear and breaks through changes in resistance or continuity, allowing for early warning and maintenance scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electrically conductive insert is embedded in the hose wall separate from the reinforcing element, then wear detection capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the wear detection function with the existing hose structure by embedding an electrically conductive insert within the hose wall. This insert forms part of an electrical circuit that detects wear through changes in electrical resistance or continuity, merging the monitoring function into the hose itself rather than adding separate external sensors.
Solution Approach 2:
The electrically conductive insert acts as an intermediary element between the hose wall and the monitoring system. It is embedded in the hose wall at a distance from the reinforcing element, serving as a mediator that translates physical wear into measurable electrical signal changes without requiring direct contact with the hose interior or exterior.
2Measurement precision
If the insert and reinforcing element are electrically insulated from one another, then wear measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by creating distinct electrical zones within the hose wall. The insert is positioned at a specific distance from the reinforcing element, and electrical insulation is applied locally between these two conductive elements. This localized differentiation allows precise measurement of wear-induced resistance changes while maintaining structural integrity.
3Reliability
If electrical conductors are embedded in the hose wall, then wear detection capability is improved, but ease of manufacture decreases
Solution Approach 1:
The electrically conductive insert is embedded in the hose wall during the manufacturing process, before the hose is put into service. This preliminary integration ensures proper positioning and insulation between the insert and reinforcing element, simplifying subsequent installation and monitoring operations while maintaining manufacturing feasibility through standardized production techniques.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables timely detection of hose line wear and potential leaks, reducing repair costs and downtime by providing a warning system that alerts users before significant damage occurs.
Implementation Method 1
the first end of the hose assembly and the first end of the insert are connected to an electrical resistance or continuity meter... the measured electrical resistance also changes. This change can be recorded and displayed by the ohmmeter
Implementation Method 2
an electrically conductive material is at least partially embedded in the hose wall and extends in the hose direction at a distance from the reinforcing element
