Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hoses used for conveying liquids with solids face issues with internal abrasion, leading to reduced strength and potential failure, which is difficult to detect efficiently, especially when multiple hoses are connected, causing interruptions in liquid delivery.
Innovation Solution
Incorporating sensor lines, either as helically wound metal wires or metal mesh strips, embedded in the hose wall to detect wear and damage, allowing for reliable detection through simple sensor technology, even under mechanical bending and stretching, without risking the sensor lines' integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inspection methods with colored markings are used to detect hose wear, then wear detection capability is provided, but inspection effort and expense increase significantly
Solution Approach 1:
The hose structure itself serves the dual function of containing fluid and detecting wear through embedded sensor lines. The sensor lines are integrated into the hose wall, allowing the hose to self-monitor its condition without requiring external inspection equipment or procedures
Solution Approach 2:
Manual inspection procedures are replaced with an automated sensor-based detection system. The sensor lines provide continuous monitoring through electrical or optical signals, eliminating the need for manual interruption, flushing, and visual inspection
2Measurement precision
If transponders are embedded in the hose wall for damage detection, then wear detection capability is improved, but manufacturing complexity and sensor vulnerability increase
Solution Approach 1:
The sensor lines are designed as simple, robust elements that can be easily manufactured and integrated into the hose. They are made from conventional materials like metal wires or conductive polymers that are inexpensive and can be produced using standard hose manufacturing processes
Solution Approach 2:
The sensor lines are made from materials and structures that are homogeneous with the hose wall environment. The sensor lines are embedded within the same elastomeric base material, creating a uniform structure that simplifies manufacturing and ensures consistent mechanical properties throughout
3Measurement precision
If rigid transponders are used for wear detection, then detection capability is provided, but reliability under mechanical stress decreases
Solution Approach 1:
The sensor lines are designed to be flexible and dynamic rather than rigid. They can bend, stretch, and deform with the hose wall without breaking, maintaining their sensing capability under various mechanical conditions including bending, stretching, and compression
